beyond carbon pricing the role of banking and monetary policy in financing the transition to a low carbon economy it is widely acknowledged that introducing a price on carbon represents a crucial precondition for filling the current gap in low carbon investment however as this paper argues carbon pricing in itself may not be sufficient this is due to the existence of market failures in the process of creation and allocation of credit that may lead commercial banks the most important source of external finance for firms not to respond as expected to price signals under certain economic conditions banks would shy away from lending to low carbon activities even in the presence of a carbon price this possibility calls for the implementation of additional policies not based on prices in particular the paper discusses the potential role of monetary policies and macroprudential financial regulation modifying the incentives and constraints that banks face when deciding their lending strategy through for instance a differentiation of reserve requirements according to the destination of lending may fruitfully expand credit creation directed towards low carbon sectors this seems to be especially feasible in emerging economies where the central banking framework usually allows for a stronger public control on credit allocation and a wider range of monetary policy instruments than the sole interest rate

the value of corporate voting rights and control a cross country analysis this paper measures the value of corporate voting rights specifically of the control block of votes in a sample of 661 dual class firms in 18 countries in 1997 a consistent measure across countries is proposed the measure is adjusted for takeover probability block holding costs and dividend and liquidity differences between the share classes the value of controlblock votes varies widely across countries it is close to half of firm market value in south korea andclose to zero in finland the value of control block votes is interpretedas a lower bound for actual private benefits of the controlling shareholder the legal environment law enforcement investor protection takeover regulations andpower concentrating corporate charter provisions explain 68 of the cross country variation in the value of control block votes

cost competitive incentives for wind energy development in china institutional dynamics and policy changes abstract this paper presents an overview of the development of wind power in china the factors that affect the directions of wind power development are analyzed it examines the economics of windfarm development and compares it with conventional energy sources the major constraints in wind technology development and defects of the current policies are discussed it points out that wind power development should be subject to rational policy change and institutional adjustment it discusses the incentive mechanisms and institutional frameworks for future development particular importance is attributed to market incentives for wind power to reach the objectives of industrialization and commercialization a number of cost competitive incentive measures and policies are recommended i introducing market based mechanisms through standard power purchase agreement ii establishing effective investment policies and regulations to attract private investment iii promoting localization of wind turbine production iv adjusting tax and subsidy policies and v reforming governmental institutions to make clear rules and responsibilities for policymaking and enhancing communication coordination between relevant government agencies in order to formulate uniform and effective policies

antitakeover charter amendments and stockholder wealth abstract many large corporations have recently adopted antitakeover charter amendments which make the transfer of corporate control more difficult this paper develops and tests competing theoretical explanations for the passage of these amendments in one view antitakeover provisions are adopted because incumbent management seeks job protection at stockholders expense the alternative hypothesis is that antitakeover provisions benefit stockholders perhaps by extracting greater payment in exchange for corporate control although inconclusive the evidence provides weak preliminary support for the hypothesis that antitakeover amendments are best explained as a device for managerial entrenchment

implications of carbon cap and trade for us voluntary renewable energy markets many consumers today are purchasing renewable energy in large part for the greenhouse gas ghg emissions benefits that they provide emerging carbon regulation in the us has the potential to affect existing markets for renewable energy carbon cap and trade programs are now under development in the northeast under the regional greenhouse gas initiative rggi and in early stages of development in the west and midwest there is increasing discussion about carbon regulation at the national level as well while renewable energy will likely benefit from carbon cap and trade programs because compliance with the cap will increase the costs of fossil fuel generation cap and trade programs can also impact the ability of renewable energy generation to affect overall co2 emissions levels and obtain value for those emissions benefits this paper summarizes key issues for renewable energy markets that are emerging with carbon regulation such as the implications for emissions benefits claims and voluntary market demand and the use of renewable energy certificates recs in multiple markets it also explores policy options under consideration for designing carbon policies to enable carbon markets and renewable energy markets to work together published by elsevier ltd

lead markets and regulation a framework for analyzing the international diffusion of environmental innovations abstract environmental regulations are often intended to stimulate the generation and adoption of eco efficient innovations an important argument in the public debate is also the creation of new markets for environmentally benign products processes and services in other countries and the generation as a result of export opportunities for the pioneering country lead markets research on lead markets has not however focused on environmental innovations to date we therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations in particular the public good character of environmental benefits and the role of regulations this approach is applied to two case studies wind energy and fuel efficient passenger cars in both cases the innovation was initially adopted in one country other countries subsequently adopted the same innovation design favored by the lead market which in turn developed into a large exporter in the wind generation and car industries respectively we discuss the regulations employed and the reasons for the international success of the innovations induced by them our findings demonstrate that when supported by global demand or regulatory trends strict regulation results in the creation of lead markets finally we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy

relative prices of dual class shares empirical studies of dual class shares indicate that superior voting shares svs sell at a premium relative to their counterpart restricted shares rvs this paper uses toronto stock exchange data to show that svs price premium over rvs reflects the expected takeover premium paid to shareholders outside the control block thus marginal shareholders pay a higher svs price in anticipation of receiving a differential takeover bid as suggested by the extra merger hypothesis further analysis indicates that voting power increases the price premium while ownership size and the higher trading liquidity of rvs are inversely related to the premium

overcoming barriers to innovation and diffusion of cleaner technologies some features of a sustainable innovation policy regime despite a deepening understanding of systems and processes by which the innovation and diffusion of cleaner technologies occurs relatively little attention has been given to the development of policy processes that reflect this deeper understanding a set of guiding principles for improving sustainable innovation policy processes has been formulated and disseminated by the authors and colleagues in research drawing on theoretical and empirical analysis including a case study of low carbon energy innovation in the uk and interactions with policy makers and other stakeholders through a series of workshops this paper elaborates on two of the guiding principles 1 stimulating the development of a sustainable innovation policy regime bringing together innovation and environmental policy regimes 2 applying systems thinking engaging with the complexity and systemic interactions of innovation systems and policy making processes to promote a transition to sustainability

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

envisaging feed in tariffs for solar photovoltaic electricity european lessons for canada abstract while it is widely agreed that support schemes need to be put in place to promote the use of renewable electricity there is less consensus as to what are the best kinds of strategies to use what is attracting increasing attention in canada is a system of renewable portfolio standards in this all power suppliers are under an obligation to ensure that a certain percentage of the electricity they generate is from renewable resources they can either generate that electricity themselves or purchase green certificates from those who have used renewables to generate electricity recent experience from europe however suggests that a whole hearted commitment to this single strategy could be premature and potentially damaging for the development of all kinds of renewable electricity in canada solar photovoltaics included on the other side of the atlantic ocean the use of so called feed in tariffs that is an obligation for utilities to purchase at a set price the electricity generated by any renewable energy resource is widely credited with accelerating the development of renewable electricity in many countries the purpose of this article is to reflect upon this european experience with feed in tariffs to stimulate discussions regarding what promise they might hold for the development of solar photovoltaic electricity in canada the article is divided into three main sections in the first section policies to promote renewable electricity presently in place in different parts of canada are reviewed attention is then focused more specifically in the second section of this article upon feed in tariffs after defining and describing this alternative system experiences in the countries of the european union are reviewed the main strengths and weaknesses of feed in tariffs in the european experience are also examined the focus then moves back to canada in the third section of the article in this a system of feed in tariffs is proposed for the province of ontario in order to provide just one example of the kind of support that could be forthcoming

takeover bids and the relative prices of shares that differ in their voting rights the relative prices of shares that differ only in their voting rights are modelled in our model voting rights become valuable when a control contest is decided through takeover bids for outside votes the study shows how the value of the voting right depends on the initial ownership distribution the share structure and the ability of the incumbent manager versus a rival for control empirical support for the model is provided using swedish stock market data

managerial ownership of voting rights abstract managers of firms with dual classes of common stock can choose different quantities of votes for a given cash flow interest by choosing different quantities of the two securities we study managerial stock holdings in 45 dual class firms and find that vote ownership per se is an important motivation for these holdings in that corporate officers and their families hold a median 56 9 of the votes and 24 0 of the common stock cash flows we also find significant family involvement in many sample firms and document four case studies in which explicit acquisition premiums were paid for superior voting shares

accelerating the transition to sustainable energy systems abstract the slow pace of transition to sustainable energy systems is the result of several factors running in parallel the starting points are very low even 30 per annum increases in rated capacity for wind energy or solar pv for example take many years to make a big impact at the global level policy initiatives are for the most part ineffectual in relation to the urgency and scale of what is required and often fail to address the fundamental causes of this slow progress this reflects a top down approach often accompanied by unrealistic targets and simultaneously undermined by a lack of consistency across policies which reflect a utopian social engineering mentality made worse because the planner s response to failure of previous interventions is to do more intensive and comprehensive interventions as william easterly has put it in short there is little or no accountability this approach has failed to harness the sympathy imagination self interest or sound options of energy users although it may attract developers including those not hitherto noted for renewable energy projects or environmental concern targets are usually too short term and clearly unrealistic especially where fossil fuel use is rising very rapidly and renewable energy use expands modestly government subsidies for traditional energy forms continue insufficient attention is paid to what individuals might achieve in energy efficiency and renewable energy terms if permitted to have or retain in industrialized countries where the burden of taxation is often inhibiting the wherewithal to make the necessary investments subsidy systems often promote renewable energy schemes that are misdirected and buoyed up by grossly exaggerated claims one or two mature renewable energy technologies are pushed nationally with insufficient regard for their costs contribution to electricity generation transportation fuels needs or carbon emission avoidance investors are rewarded excessively under some national schemes for mature technologies that should not require support and that frequently do not make the contribution to renewable energy output or carbon emission avoidance they claim costs to business and domestic electricity consumers through the subsidy payments they make are much greater under some schemes than what other carbon abatement measures would cost higher cost less mature renewable energy technologies that have large potential for meeting global energy needs are not getting the support they warrant this is of grave concern given the minimum 30 50 year lead times required to make a large global contribution without departing from the sense of urgency required to address the pressing needs for sustainable energy systems it is imperative that the involvement of people at the grassroots level is harnessed and sound commercial and technical criteria are applied

the value of the corporate voting right evidence from switzerland abstract this paper analyzes the value of voting power of swiss firms which usually issue high voting rights stock low voting rights stock and non voting stock two variables measuring voting power inequality are constructed they are both useful in explaining the voting rights premia also the allocation of the voting rights is analyzed it is shown that majority shareholders hold the high voting rights stock

policies and market factors driving wind power development in the united states abstract in the united states there has been substantial recent growth in wind energy generating capacity with growth averaging 24 percent annually during the past five years about 1700 mw of wind energy capacity was installed in 2001 while another 410 mw became operational in 2002 during 2003 development activity has remained strong with an estimated 1600 mw of capacity installed with this growth an increasing number of states are experiencing investment in wind energy projects currently about half of all states host at least one wind power project this paper explores the key factors at play in the 12 states in which a substantial amount of wind energy capacity has been developed or planned some of the factors that are examined include policy drivers such as renewable portfolio standards rps federal and state financial incentives as well as market drivers such as consumer demand for green power natural gas price volatility and wholesale market rules

the price of policy risk empirical insights from choice experiments with european photovoltaic project developers managing the transition to a renewable energy future is an important policy priority in many countries solar photovoltaic pv technology is expected to make an important contribution but due to relatively higher cost its growth to date has been largely driven by public policy notably feed in tariffs feed in tariffs have been implemented in various countries however with widely differing outcomes in terms of installed pv capacity previous research indicates that the level of policy risk may be an important driver for differences in renewable energy policy effectiveness more specifically we suggest that investors who take a decision between pv investment opportunities in different countries carefully weigh feed in tariff induced returns against a set of policy risks and choose the country with the most favorable risk return profile we empirically test this model based on a stated preference survey among european pv project developers consisting of 1575 choice decisions by 63 investors the findings of our study demonstrate that risk matters in pv policy design and that a price tag can be attached to specific policy risks such as the duration of administrative processes or uncertainty induced by an approaching capacity cap governments can build on our empirical results to design policies that will be effective in attracting private pv investment while at the same time maintaining efficiency by providing an adequate compensation for policy risk

policy instruments fostering wind energy projects a multi perspective evaluation approach abstract during the last decade a large number of policy instruments have been developed and implemented all over europe aiming at supporting renewable energy project development however the success of the different policy approaches varies significantly given the very different mechanisms of the diverse instruments the design or the selection of appropriate instruments may cause methodological difficulties in order to support instrument selection economists have developed several evaluation criteria however this paper states that most of the typically proposed and applied criteria catalogues still neglect the interests and requirements of important stakeholder groups this paper therefore proposes a more integrated evaluation approach taking into account the different interests of all relevant stakeholder groups in the three fields renewable energy business especially wind industry policy making and conventional power business

comparing the innovation effects of support schemes for renewable electricity technologies a function of innovation approach abstract the aim of this paper is to provide a comparative assessment of the innovation effects of instruments which support the diffusion of renewable electricity technologies with a functions oriented technological innovation system perspective the paper provides a link between two major streams of the literature the functions of innovation systems and the literature on renewable electricity support schemes we show that when a functional perspective is adopted feed in tariffs are likely to be superior to other policy instruments quotas with tradable green certificates and tendering although they still need to be complemented with other instruments most importantly direct r d support furthermore those innovation effects are affected by the specific design elements of the instruments chosen

factors influencing the likelihood of regulatory changes in renewable electricity policies abstract the renewable electricity literature has expanded in recent years from the analysis of policies focused on research and development rd the coherence of the policies the size and variety of the coalitions supporting and opposing renewable electricity and the brussels effect the importance of these factors is evaluated in the case of three major markets of renewable electricity germany the netherlands and denmark

alternatives to coal and candles wind power in china china is in a unique position to be able to exploit her vast wind resources to satisfy both the rapidly growing energy demand which fuels her economy as well as needs of approximately 72 million people who live in rural areas and have no access to conventional electricity services china mainly through the e orts of the inner mongolia autonomous region has already successfully disseminated over 150 000 small scale wind electric generators which power households in rural areas through a well coordinated combination of local research and development technology transfer industry support end user incentives and an infrastructure for information dissemination and technical training in this paper we review china s utilization of wind energy and discuss how it can be increased for both rural electri cation and the rapidly growing power sector we nd that novel approaches in technical implementation of wind power use may help to better meet china s needs use of hybrid systems may help to provide higher quality more reliable power for rural households and villages than is currently provided through wind only systems grid connected wind power which currently is more costly and less reliable than coal power can become cost competitive and more reliable through local mass production of wind turbines combined with storage systems we examine governmental support through policy infrastructure development and nancial incentives that have fostered the successes of dissemination of small scale wind turbines and also the support or lack thereof that has hindered commercial development of large scale wind power we nd that a better policy and regulatory framework is the most important measure that china can take to increase the use of this indigenous clean resource 2000 elsevier science ltd all rights reserved

the effects of economic and policy incentives on carbon mitigation technologies the ability to estimate the likely effects of potential climate change policies on energy use and greenhouse gas ghg emissions requires an improved understanding of the relationship between different policy alternatives and energy saving and ghg reducing changes in technology a particularly important and understudied aspect of this set of issues is the conceptual and empirical modeling of how the various stages of technological change are interrelated how they unfold over time in response to market forces and the differential impact of various policies for example r d subsidies environmental taxes information programs we summarize several contributions to this literature and suggest promising areas for continued research on empirical analysis and modeling of induced technological change

r d investment strategy for climate change abstract the economic costs of stabilizing greenhouse gas concentrations over the coming century depend critically on the development of new technologies in the energy sector our research and development r d investment strategy is the control variable for technology availability this paper proposes an analytic framework for determining optimal r d investment allocation and presents some numerical results to demonstrate the implementation of the methodology the value of technological advance in three targeted areas fossil based generation renewables and carbon capture and storage is represented by the increase in expected welfare in the presence of an emissions policy constraint of initially uncertain stringency r d expenditure increases the probability of advance optimal investment is determined by its relationship with success probability which is assumed to exhibit decreasing returns to scale relative to the value of success while the numerical results are speculative the paper offers insights into the nature of an optimal technology strategy for addressing climate change

the two faces of market support how deployment policies affect technological exploration and exploitation in the solar photovoltaic industry the recent years have seen a strong rise in policies aiming to increase the diffusion of clean energy technologies while there is general agreement that such deployment policies have been very effective in bringing technologies to the market it is less understood how these policies affect technological innovation to shed more light on this important question we conducted comparative case studies with a global sample of 9 firms producing solar photovoltaic pv modules complemented by in depth interviews with 16 leading pv industry experts we propose that on the one hand policy induced market growth serves as an important catalyst for innovative activity as it raises the absolute level of firm investments in technological exploration on the other hand however deployment policies create an incentive for firms pursuing more mature technologies to shift their balance between exploitation and exploration toward exploitation firms focusing on less mature technologies cannot tap the potentials of exploitative learning to the same extent as those with more mature technologies therefore stimulating strong market growth may raise the barrier to market entry for less mature technologies we conclude that when designing deployment policies great care should be taken to avoid adverse effects on technological diversity and a premature lock in into more established technologies

governing sustainability transitions through business model innovation towards a systems understanding this paper examines the role of innovative business models in the transformation of socio technical systems focusing on decentralised energy technologies we explore business model innovation in the context of a transition towards a more sustainable energy system we conduct an empirical study of two energy services company esco models for the deployment of combined heat and power with district heating chp dh infrastructure in the uk based on these case studies we illustrate the different ways in which local authorities develop business models to create and capture value from more efficient resource use and to deploy sustainable technologies drawing from systems theories in the business model and socio technical literatures we analyse the interfaces between business models energy infrastructure and institutions we propose that a systems based approach to the analysis of business models as embedded in their socio technical contexts can offer new insights into the dynamics and governance of sustainability transitions

advanced solar r d combining economic analysis with expert elicitations to inform climate policy the relationship between r d investments and technical change is inherently uncertain in this paper we combine economics and decision analysis to incorporate the uncertainty of technical change into climate change policy analysis we present the results of an expert elicitation on the prospects for technical change in advanced solar photovoltaics we then use the results of the expert elicitations as inputs to the minicam integrated assessment model to derive probabilistic information about the impacts of r d investments on the costs of emissions abatement

incomplete information high low bidding and public information in first price auctions high low bidding refers to auctions of a series of objects where for a subset of the auctioned objects one of two buyers bids high on some objects and low on others while the other buyer does the reverse this paper shows that high low bidding does not imply collusive behavior among buyers in particular through a formal modeling of a noncooperative game of information acquisition and bidding decisions it shows that high low bidding can be obtained the paper also demonstrates that if the cost of information to a seller is less than the equilibrium joint expected information cost of the buyers then it pays the seller to provide public information finally if the provision of public information is not feasible but a seller can know whether buyers have acquired information then it pays the seller to make known to the buyers and to pursue a policy that just prior to the start of an auction the seller will announce which buyer has acquired information

the renewables portfolio standard in texas an early assessment texas has rapidly emerged as one of the leading wind power markets in the united states this development can be largely traced to a well designed and carefully implemented renewables portfolio standard rps the rps is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation though replacing existing renewable energy policies with an as of yet untested approach in the rps is risky early experience from texas suggests that an rps can effectively spur renewables development and encourage competition among renewable energy producers initial rps targets in texas were well exceeded by the end of 2001 with 915 mw of wind installed in that year alone rps compliance costs appear negligible with new wind projects reportedly contracted for well under 3 us cent k wh in part as a result of a 1 7 us cent kwh production tax credit an outstanding wind resource and an rps that is sizable enough to drive project economies of scale obliged retail suppliers have been willing to enter into long term contracts with renewable generators reducing important risks for both the developer and the retail supplier finally the country s first comprehensive renewable energy certificate program has been put into place to monitor and track rps compliance c 2002 published by elsevier science ltd less

barriers to energy efficiency a comparison across the german commercial and services sector abstract based on a large sample for the german commercial and services sector this paper econometrically assesses the relevance of various types of barriers to energy efficiency at the sectoral level and across fifteen sub sectors the results at the level of entire sectors suggest that the lack of information about energy consumption patterns and about energy efficiency measures lack of staff time priority setting within organizations and in particular the investor user dilemma are all relevant barriers allowing for sector specific differences in the relevance of these individual barriers yields a more heterogeneous picture the numbers and types of relevant barriers vary across sub sectors and the majority of sub sectors are subject to relatively few barriers the statistically most significant barriers are found for the sub sector of public administrations these findings are robust independent of whether the definition of an organization s energy efficiency performance includes only measures that have actually been realized or also those that are being planned for planned projects however organizations appear to underestimate internal priority setting as a barrier to energy efficiency

neither crowding in nor out public direct investment mobilising private investment into renewable electricity projects abstract rapid structural change towards a low carbon energy supply requires significant additional investments into innovative but high risk low carbon technologies mobilising greater private investments requires applying the right policy instruments but while fiscal measures and regulation have been well researched systematic quantitative evidence about the effect of public direct investment is lacking absent empirical evidence contradictory theoretical arguments claim that such public co investments either crowd out or crowd in private investors in this paper we show that the macroeconomic concept of crowding out in is inapplicable to sectoral studies such as of renewable electricity instead both neoclassical microeconomics and evolutionary economics suggest public direct investment to have a positive effect due to either externalities or market creation effects we also provide the first quantitative estimate of the effect of public direct investment on private investment into renewable electricity technologies for 17 countries in the period 2004 2014 using fgls and static and dynamic gmm estimators we find that public investments not only have a positive but also consistently the largest effect on private investment flows relative to feed in tariffs taxes and renewable portfolio standards in general and for wind and solar technologies separately implications for policy aimed at accelerating the low carbon transition are discussed

transforming the energy sector the evolution of technological systems in renewable energy technology this paper analyses the development and diffusion of technologies that utilize renewable energy sources in germany sweden and the netherlands the analysis enlarges the life cycle model of industry evolution to one where the focus is on the formation and evolution of new technological systems particular focus is on explaining success and failures in shifting from a formative phase into one characterized by positive feedbacks a set of challenges is identified for policy makers attempting to influence the process of transforming the energy sector

financing investment in the european electricity transmission network consequences on long term sustainability of the tsos financial structure this article focuses on the ability of european tsos to meet the demand for substantial investments in the electricity transmission grid over the next two decades we employ quantitative analysis to assess the impact of the required capital expenditures under a set of alternative financing strategies we consider a best case scenario of full cooperation between the european tsos it appears that under current trends in the evolution of transmission tariffs only half the volumes of investment currently planned could be funded a highly significant increase in transmission tariffs will be required to ensure the whole scale investments can be delivered finally alternative strategies can dampen the impact on tariffs but they can only partially substitute for this increase in charges paid by network users

rejecting renewables the socio technical impediments to renewable electricity in the united states if renewable power systems deliver such impressive benefits why do they still provide only 3 percent of national electricity generation in the united states as an answer this article demonstrates that the impediments to renewable power are socio technical a term that encompasses the technological social political regulatory and cultural aspects of electricity supply and use extensive interviews of public utility commissioners utility managers system operators manufacturers researchers business owners and ordinary consumers reveal that it is these socio technical barriers that often explain why wind solar biomass geothermal and hydroelectric power sources are not embraced utility operators reject renewable resources because they are trained to think only in terms of big conventional power plants consumers practically ignore renewable power systems because they are not given accurate price signals about electricity consumption intentional market distortions such as subsidies and unintentional market distortions such as split incentives prevent consumers from becoming fully invested in their electricity choices as a result newer and cleaner technologies that may offer social and environmental benefits but are not consistent with the dominant paradigm of the electricity industry continue to face comparative rejection

technological learning and renewable energy costs implications for us renewable energy policy abstract this paper analyzes the relationship between current renewable energy technology costs and cumulative production research development and demonstration expenditures and other institutional influences combining the theoretical framework of learning by doing and developments in learning by searching with the fields of organizational learning and institutional economics offers a complete methodological framework to examine the underlying capital cost trajectory when developing electricity cost estimates used in energy policy planning models sensitivities of the learning rates for global wind and solar photovoltaic technologies to changes in the model parameters are tested the implications of the results indicate that institutional policy instruments play an important role for these technologies to achieve cost reductions and further market adoption

strategic choices for renewable energy investment conceptual framework and opportunities for further research this paper introduces the special issue on strategic choices for renewable energy investment which is a collection of best papers presented at an international research conference held in st gallen switzerland in february 2010 substantial private investment is needed if public policy objectives to increase the share of renewable energy and prevent dangerous anthropogenic climate change are to be achieved the aim of this paper and the entire special issue is to draw scholarly attention to the processes underlying strategic choices for renewable energy investment and how they are influenced by energy policy we disentangle the role of risk return perceptions portfolio effects and path dependence in explaining energy investment decisions and suggest that the heterogeneous universe of investors requires a segmentation of policies the paper outlines some of the rich opportunities for further research in this emerging area

financing investments in renewable energy the impacts of policy design abstract the costs of electric power projects utilizing renewable energy technologies rets are highly sensitive to financing terms consequently as the electricity industry is restructured and new renewables policies are created it is important for policymakers to consider the impacts of renewables policy design on ret financing this paper reviews the power plant financing process for renewable energy projects estimates the impact of financing terms on levelized energy costs and provides insights to policymakers on the important nexus between renewables policy design and financing we review five case studies of renewable energy policies and find that one of the key reasons that ret policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy policies the case studies specifically show that policies that do not provide long term stability or that have negative secondary impacts on investment decisions will increase financing costs sometimes dramatically reducing the effectiveness of the program within u s electricity restructuring proceedings new renewable energy policies are being created and restructuring itself is changing the way rets are financed as these new policies are created and implemented it is essential that policymakers acknowledge the financing difficulties faced by renewables developers and pay special attention to the impacts of renewables policy design on financing as shown in this paper a renewables policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will in turn reduce financing risk premiums

economic evaluation of voting power of common stock this paper presents an economic evaluation of common stock voting rights an index of relative voting rights inequality for different classes of stock of the same corporation is constructed and the empirical relationship between the market premium on a superiorvoting stock and the voting inequality index is examined in only three out of the 25 cases could investors have arbitraged between the two classes of stock although in one case the arbitrage opportunity persisted for several months ownership and control of large corporations are two separate functions each shareholder typically holds a relatively small number of shares and hence lacks significant voting power as a result shareholders interest in the management of the firm is typically limited and a majority of them do not participate in the corporation s general meetings 1 thus the investment and financial decisions of the firm are made by a small group the management which effectively controls the firm the possible conflict of interest between these two groups and other various aspects of the separation of control and ownership are the subject of several studies 2 grossman and hart 5 show that even if the directors of the firm do not act in the best interest of the shareholders 3 it may be impossible for them to be disciplined and replaced by a takeover bid this raises the issue of whether theright to control the firm s activities has any economic value to focus the issue suppose a firm issues two classes of stock one with voting rights and the other with no voting rights and assume further that the two classes are entitled to the same pecuniary payoff in every state of the world according to traditional financial theory that asserts that two assets promising the same payoff in every state of nature must sell for the same price the voting rights would be worthless and we should expect the same market price for the two classes of stock however

technology policy and global warming why new policy models are needed or why putting new wine in old bottles won t work in recent years the threat of global climate change has come to be seen as one of the most serious confronting humanity to meet this challenge will require the development of new technologies and the substantial improvement of existing ones as well as ensuring their prompt and widespread deployment some have argued that the urgency of the situation requires a manhattan project or an apollo program this paper examines why such a policy model is inappropriate arguing that the nature of the policy context for confronting climate change necessitates a different kind of technology policy than that for building an atomic bomb or for achieving a manned lunar landing instead it seeks to draw lessons from three sectors that seem to be more pertinent and where government technological development and deployment programs have been pursued with some success in the united states namely agriculture biomedical research and information technology it compares and contrasts these with the policies pursued with regard to the first two of these sectors in the united kingdom the paper concludes by drawing out the implications for the design of policies supporting technological development and innovation to address the problem of global climate change

which renewable energy policy is a venture capitalist s best friend empirical evidence from a survey of international cleantech investors governments around the world have adopted ambitious targets to increase the share of renewable energy and reduce greenhouse gas emissions they pursue a variety of policy approaches to achieve these targets it has been a popular theme for contributions in energy policy to investigate the effectiveness of such policies this article adds a new perspective to the debate namely looking at the policy preferences of private investors in innovative clean energy technology firms we surveyed 60 investment professionals from european and north american venture capital and private equity funds and asked them to assess the effectiveness of various policies in terms of stimulating their interest to invest in innovative clean energy technologies in addition to quantitative rankings we use qualitative interview data to capture additional information on why investors prefer some policies over others the combined analysis compensates for the inherent limitations of a quantitative ranking using generic policy types the results of this exploratory analysis demonstrate that all other things being equal investors in our sample perceived feed in tariffs to be the most effective renewable energy policy the overall preference for feed in tariffs is even more pronounced among investors based in europe and with higher exposure to clean energy

u s energy research and development declining investment increasing need and the feasibility of expansion investment in energy research and development in the u s is declining despite calls for an enhancement of the nation s capacity for innovation to address environmental geopolitical and macroeconomic concerns we examine investments in research and development in the energy sector and observe broad based declines in funding since the mid 1990s the large reductions in investment by the private sector should be a particular area of concern for policy makers multiple measures of patenting activity reveal widespread declines in innovative activity that are correlated with research and development r d investment notably in the environmentally significant wind and solar areas trends in venture capital investment and fuel cell innovation are two promising cases that run counter to the overall trends in the sector we draw on prior work on the optimal level of energy r d to identify a range of values which would be adequate to address energy related concerns comparing simple scenarios based on this range to past public r d programs and industry investment data indicates that a five to ten fold increase in energy r d investment is both warranted and feasible

reputation and decision making under ambiguity a study of u s venture capital firms investments in the emerging clean energy sector this study examines the role of reputation on decision making under ambiguity drawing on social cognition and behavioral theories we propose that a firm s reputation exerts dual pressures on its decision making under ambiguity on the one hand a firm s reputation increases its aspirations for future performance and promotes its engagement in risky strategies to achieve them on the other hand preserving the already established reputation requires a firm to deliver consistent performance over time which promotes greater use of risk reduction strategies our analyses of the u s venture capital firms investments in the clean energy sector from 1990 to 2008 demonstrate that while reputable firms are more likely to invest in the emerging sector they also employ risk reduction strategies more extensively the sector s legitimation further influences these firms investment decisions both directly and through its interaction with firm reputation

investment barriers and incentives for marine renewable energy in the uk an analysis of investor preferences abstract deployment of marine renewable energy mre in the uk is desirable in order to address climate change meet mandatory eu renewable energy targets and provide significant economic development opportunities including new export markets public funding constraints in the uk mean that substantial investment is required from the private sector to commercialize the industry by focussing on investor attitudes and behaviours towards wave and tidal technologies this paper reveals significant observations from the investment community with serious implications for the future of the mre industry through a series of in depth interviews with individuals from the investment community device developers and industry support the research seeks to identify common barriers and incentives to investment the paper demonstrates that although investors attitudes are generally aligned they do appear to have changed over time of the participants that had previously invested in early stage mre device development none were likely to do so again it is concluded that this is a function of investors greater understanding of the scale and unpredictability of the costs and the length of time required to develop these technologies this presents a significant policy challenge for all actors interested in the commercialization of wave and tidal technologies

a tale of two market failures technology and environmental policy abstract market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies these combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives and can be cost effectively harnessed through the use of economic incentive based policy in the presence of weak or nonexistent environmental policies investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable positive knowledge and adoption spillovers and information problems can further weaken innovation incentives while environmental technology policy is fraught with difficulties a long term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

environmental policies and risk finance in the green sector cross country evidence abstract this paper provides a detailed description of venture capital investment in the green sector across 29 countries over the period 2005 2010 and identifies the role that policies might play in explaining observed cross country differences the analysis is based on a deal level database of businesses seeking financing combined with indicators of renewable policies and government r d expenditures the econometric analysis relates the number of deals and their volumes in a country to deployment and supply policies using count data and limited dependent variable tobit models the results suggest that both supply side policies and environmental deployment policies designed with a long term perspective of creating a market for environmental technologies are associated with higher levels of venture capital relative to more short term fiscal policies when focusing on policies related to renewable energy generation the results confirm the positive association of generous feed in tariffs fits with venture capital investment however in the solar sector excessively generous fits tend to discourage investment perhaps reflecting a lack of credibility over the longer term thus both sets of results point to long term policy stability sustainability and credibility as important policy features to ensure venture capital backing of innovative and risky ventures in a country s green sector

who invests in renewable electricity production empirical evidence and suggestions for further research transforming energy systems to fulfill the needs of a low carbon economy requires large investments in renewable electricity production res e recent literature underlines the need to take a closer look at the composition of the res e investor group in order to understand the motives and investment processes of different types of investors however existing energy policies generally consider res e investments made on a regional or national level and target investors who evaluate their res e investments according to least cost high profit criteria we present empirical evidence to show that res e investments are made by a heterogeneous group of investors that a variety of investors exist and that their formation varies among the different types of renewable sources this has direct implications for our understanding of the investment process in res e and for the study of motives and driving forces of res e investors we introduce a multi dimensional framework for analyzing differences between categories of investors which not only considers to the standard economic dimension which is predominant in the contemporary energy literature but also considers the entrepreneurship innovation adoption and institutional dimensions the framework emphasizes the influence of four main investor related factors on the investment process which should be studied in future research motives background resources and personal characteristics

uk innovation systems for new and renewable energy technologies drivers barriers and systems failures abstract a better understanding of the systemic processes by which innovation occurs is useful both conceptually and to inform policy making in support of innovation in more sustainable technologies this paper analyses current innovation systems in the uk for a range of new and renewable energy technologies and generates policy recommendations for improving the effectiveness of these innovation systems although incentives are in place in the uk to encourage innovation in these technologies system failures or gaps are identified in moving technologies along the innovation chain preventing their successful commercialisation sustained investment will be needed for these technologies to achieve their potential it is argued that a stable and consistent policy framework is required to help create the conditions for this in particular such a framework should be aimed at improving risk reward ratios for demonstration and pre commercial stage technologies this would enhance positive expectations stimulate learning effects leading to cost reductions and increase the likelihood of successful commercialisation

induced innovations and climate change policy with the recent progress in bonn and marrakech on the details required for implementing the kyoto protocol entry into force in 2003 is now a possibility this paper assesses the potential macroeconomic impacts of the kyoto protocol given the recent negotiated developments in addition given the recent attempts in the literature to model endogenous technical change in general equilibrium models a new methodology for incorporating the induced innovations hypothesis into a general equilibrium model is described and implemented in line with previous work it is found that incorporation of the hypothesis reduces abatement costs

support systems for the diffusion of renewable energy technologies an investor perspective concern over climate change impacts and the projected depletion of fossil fuels has urged more governments to adopt policies that stimulate the diffusion of renewable energy technologies ret with an increasingly diverse suite of support instruments the question emerges as to which instruments or combinations are able to achieve faster more substantial diffusion results although various support instruments were extensively addressed in policy studies there is still no consensus this is partly because many policy studies take a policy maker approach in comparing support instruments leaving relationships between policy design and policy results as a black box this paper proposes an investor oriented perspective to analyze the diffusion potential of support systems for ret the main argument is that it is not the type of support instrument but rather its risk profitability characteristics that influence investor behavior and the rate of diffusion the two instruments most frequently discussed and compared are the feed in tariff and the quota model the analysis in this paper concludes that policy design is crucial while often feed in tariffs are applauded and quota system feared feed in tariffs may also bring about disappointing diffusion results when poorly designed while quota systems may be also conceived as attractive instruments for independent power producers

does the energy efficiency paradox exist technological progress and uncertainty we explain why firms may choose not to undertake investments inenergy saving technologies that appear profitable from a net presentvalue perspective as future technological advances are inherentlyuncertain and investments in new technology are at least partly irreversible it may pay to postpone investments in energy savingand wait for the arrival of improved varieties this insight casts doubton the existence of so called low hanging fruits in energy saving although we do not wish to deny that organisational failures may alsobe important failure to appreciate the underlying stochasticity oftechnological progress may obscure the insight that there is value inwaiting and costs involved in terminating the option to invest theappetite for low hanging fruits will be less when these costs areincorporated in the analysis we demonstrate that the effect of thearrival rate of new technologies on the adoption lag for a rational firmis ambiguous the same holds for the effect of the expected jump inefficiency of new technologies government policies aimed at enhancingthe adoption of new technologies through stimulation of r d maytherefore be counterproductive

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

exploring technology diffusion in emerging markets the role of public policy for wind energy abstract this study challenges the implicit assumption of homogeneity in national institutional contexts made in past studies of renewable energy policy we propose that institutional differences matter by focusing on several technology specific and generic policy factors that can foster technology diffusion through private sector activity more specifically we explore perceptions of early adopters in emerging economy contexts using wind park project developers as an example by applying a parsimonious method for our questionnaire as well as qualitative data we make several contributions methodologically we introduce maximum difference scaling to the energy policy domain empirically we identify several public influences on private investment and assess their relative importance this leads to new insights challenging findings from industrialized economies we identified additional institutional barriers to diffusion hence the requirement of a combination of technology specific and generic policy measures

prospects for global market expansion of china s wind turbine manufacturing industry abstract emerging economies are increasingly contributing to global innovation including clean tech innovation the development of china s wind power sector has often been used to illustrate this point china s domestic wind power market is the largest in the world and is largely supplied by domestic manufacturers competition for market share in the domestic market may pressure firms to innovate which consecutively improves prospects for global expansion this paper reviews developments in china s domestic wind turbine market using the technological innovation system framework we analyze the pressure to innovate arising from market competition and assess the prospects for global expansion of chinese wind turbine manufacturers we conclude that domestic customers are not pressured or incentivized to perform with respect to power output such that turbine manufacturers are not pressured to perform with respect to turbine efficiency or maintenance needs pressure to innovate is further reduced by formalizing connections between wind farm developers and turbine manufacturers chinese turbine manufacturers cannot yet compete with leading global brands in technological leadership the prospects for exports are improved however by the preferential supply of project financing from institutional investors such as the china development bank from chinese utilities that seek global expansion and from the manufacturers themselves

uncertain r d backstop technology and ghgs stabilization abstract this paper analyses optimal investments in innovation when dealing with a stringent climate target and with the uncertain effectiveness of r d the innovation needed to achieve the deep cut in emissions is modeled by a backstop carbon free technology whose cost depends on r d investments to better represent the process of technological progress we assume that r d effectiveness is uncertain by means of a simple analytical model we show how accounting for the uncertainty that characterizes technological advancement yields higher investments in innovation and lower policy costs we then confirm the results via a numerical analysis performed with a stochastic version of witch an energy economy climate model the results stress the importance of a correct specification of the technological change process in economy climate models

the role of policy instruments in the innovation and diffusion of environmentally friendlier technologies popular claims versus case study experiences abstract moving towards sustainability will require that new environmentally friendlier technologies are developed and widely adopted policy instruments that promote eco efficiency are therefore necessary some claims frequently made in the literature on the relationship between policy instruments and technological development are examined the claims concern regulations environmental taxation and funding of research and development the claims are explored on the basis of empirical evidence from two sectors the pulp and paper industry and the marine engine industry little support was found for some of the claims in some cases even contradictory findings and for some claims the findings differed between the sectors and even within a sector depending on the issue

the governance of sustainable socio technical transitions a quasi evolutionary model of socio technical transitions is described in which regimes face selection pressures continuously differentiated transition contexts determine the form and direction of regime change in response to these pressures the articulation of pressures and the degree to which responses are coordinated and based on resources available within the regime define the transition context four alternative contexts are described endogenous renewal re orientation of trajectories emergent transformation and purposive transitions agency and power in the governance of regime transformation are analysed power to affect change depends on regime membership the distribution of resources for change and expectations

technological change and uncertainty in environmental economics abstract technological change is widely believed to play a crucial role in mastering the challenges of man made climate change the drivers and impacts of technological change have therefore become an important research issue in the field of climate economics while models to analyze the interactions between economy energy and the environment initially treated technological change as exogenous more recent modeling approaches often represent technological change as endogenously induced typically models of induced technological change in climate economics are based on perfect foresight in a deterministic world however both technological change and climate impacts are subject to large uncertainties that may substantially affect the design of efficient climate policies against this background the special issue presents five articles contributing to the study of uncertainty and technological change in climate change economics

general wisdom concerning the factors affecting the adoption of cleaner technologies a survey 1990 2007 abstract cleaner technologies ct have recently received much attention in diverse media and policy agendas this comes out of the clear role they play in environmental protection and sustainability and the large potential to contribute to economic growth and competitiveness the realization of both potentials depends on the level diffusion and exploitation achieved today very low this article presents a selective survey of papers that today represent the general wisdom concerning the factors affecting adoption as a primary condition to diffusion and exploitation of ct the paper helps to clarify the challenges facing diffusion modelers and policy makers when dealing with policy design assessing the levels of diffusion achieved as well as the factors affecting diffusion of a particular technology the paper ends outlining further research need in the field

on the selection of financing instruments to push the development of new technologies application to clean energy technologies abstract achieving climate policy goals requires mobilizing public funds to bring still immature clean technologies to competitiveness and create new technological options the format of direct public support must be tailored to the characteristics of technologies addressed based on the experience accumulated with innovation programs we have identified those features of innovation that should directly condition the choice of direct support instruments these include the funding gap between the cost of innovation activities and the amount of private funds leveraged the ability of technologies targeted to compete for public funds in the market the probability that these technologies fail to reach the market and the type of entity best suited to conduct these activities clean innovation features are matched to those of direct support instruments to provide recommendations on the use to be made of each type of instrument given the large financing gap of most clean energy innovation projects public grants and contracts should finance a large part of clean pre deployment innovation however public loans equity investments prizes and tax credits or rebates can successfully support certain innovation processes at a lower public cost principles derived are applied to identify the instrument best suited to a case example

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

policy mixes for sustainability transitions an extended concept and framework for analysis reaching a better understanding of the policies and politics of transitions presents a main agenda item in the emerging field of sustainability transitions one important requirement for these transitions such as the move towards a decarbonized energy system is the redirection and acceleration of technological change for which policies play a key role in this regard several studies have argued for the need to combine different policy instruments in so called policy mixes however existing policy mix studies often fall short of reflecting the complexity and dynamics of actual policy mixes the underlying politics and the evaluation of their impacts in this paper we take a first step towards an extended interdisciplinary policy mix concept based on a review of the bodies of literature on innovation studies environmental economics and policy analysis the concept introduces a clear terminology and consists of the three building blocks elements policy processes and characteristics which can be delineated by several dimensions based on this we discuss its application as analytical framework for empirical studies analyzing the impact of the policy mix on technological change throughout the paper we illustrate the proposed concept by using the example of the policy mix for fostering the transition of the german energy system to renewable power generation technologies finally we derive policy implications and suggest avenues for future research

renewable energy policies and private sector investment evidence from financial microdata this paper analyses the effect of government policies and other determinants on private finance investment in renewable energy a unique dataset of financial transactions for renewable energy projects is constructed using the bloomberg new energy finance database the dataset covers 87 countries six renewable energy sectors wind solar biomass small hydropower marine and geothermal and the 2000 2011 time span in a first set of models undertaken at the level of the financial deal we find that in contrast to quota based schemes price based support schemes are positively correlated with private finance contributions this result holds for complementary analyses undertaken at the level of the project however for those projects in which public finance complements private finance co financed projects neither quota based measures nor price based support schemes have a significant effect on private finance flows

mobilizing private finance for low carbon innovation a systematic review of barriers and solutions this paper analyses the field of innovation studies regarding barriers to low carbon innovation and consequences for finance investment and divestment and contributes to a more holistic understanding of the underlying mechanisms a combination of technological barriers combined with economic barriers institutional and political barriers contribute to sub optimal low carbon investment all along the innovation cycle policy makers need to take a systemic approach to enable the redirection of diverse private financial sources instruments range from cutting dirty r d subsidies and support for clean technology innovation and diffusion levelling the institutional playing field and making risks of high carbon and low carbon technologies transparent to providing a consistent but adaptive long term transition strategy this would allow financiers to gradually shift their investments away from high carbon mainstream markets and scale low carbon technology niche markets however financiers also need to sharpen their competencies with regard to new clean technologies and markets

impact of public policy uncertainty on renewable energy investment wind power and the production tax credit abstract it is generally understood that the pattern of repeated expiration and short term renewal of the federal production tax credit ptc causes a boom bust cycle in wind power plant investment in the us this on off pattern is detrimental to the wind industry since ramp up and ramp down costs are high and players are deterred from making long term investments it is often assumed that the severe downturn in investment during off years implies that wind power is unviable without the ptc this assumption turns out to be unsubstantiated this paper demonstrates that it is not the absence of the ptc that causes the investment downturn during off years but rather the uncertainty over its return specifically it is the dynamic of power purchase agreement ppa negotiations in the face of ptc renewal uncertainty that drives investment volatility with contract negotiations prevalent in the renewable energy industry this finding suggests that reducing uncertainty is a crucial component of effective renewable energy policy the ptc as currently structured is not the only means existing or potential for encouraging wind power investment using data from a survey of energy professionals various policy instruments are compared in terms of their perceived stability for supporting long term investment

are tradable green certificates a cost efficient policy driving technical change or a rent generating machine lessons from sweden 2003 2008 in the european policy debate tradable green certificates tgc have been suggested to be a superior regulatory framework for promoting the diffusion of renewable electricity technologies the purpose of this paper is to assess the performance of the swedish tgc system contributing to the european debate on the suitability of different types of frameworks the expectations of the tgc system were that it would a be effective in terms of increasing the supply of green electricity b do this in a cost effective manner from both a social and a consumer perspective c generate an equitable distribution of costs and benefits and d drive technical change so far it has performed adequately in terms of effectiveness and social cost effectiveness however consumer costs have been substantially higher than expected very large rents are generated and at best it contributes marginally to technical change thus a tgc framework should be selected if the overriding concern is to minimize short term social costs of reaching a certain goal with a high degree of predictability however it cannot be expected to also drive technical change keep consumer costs down and be equitable such trade offs need to be revealed and not obscured by analysts

state renewable energy electricity policies an empirical evaluation of effectiveness over the past decade state governments have emerged as us energy policy leaders across the country states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment one of the most prevalent and innovative policy instruments is a renewable portfolio standard rps which seeks to increase the share of renewable energy electrification in the electricity market this analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state rps policy implementation and the percentage of renewable energy electricity generation across states we use a variant of a standard fixed effects model referred to as a fixed effects vector decomposition with state level data from 1998 to 2006 results indicate that rps implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix yet for each additional year that a state has an rps policy they are found to increase the total amount of renewable energy generation these findings reveal a potentially significant shortcoming of rps policies political institutions natural resource endowments deregulation gross state product per capita electricity use per person electricity price and the presence of regional rps policies are also found to be significantly related to renewable energy deployment

legitimizing research technology and innovation policies for transformative change combining insights from innovation systems and multi level perspective in a comprehensive failures framework abstract the recent policy debates about orientating research technology and innovation policy towards societal challenges rather than economic growth objectives only call for new lines of argumentation to systematically legitimize policy interventions while the multi level perspective on long term transitions has attracted quite some interest over the past years as a framework for dealing with long term processes of transformative change but the innovation systems approach is still the dominant perspective for devising innovation policy innovation systems approaches stress the importance of improving innovation capabilities of firms and the institutional settings to support them but they are less suited for dealing with the strategic challenges of transforming systems of innovation production and consumption and thus with long term challenges such as climate change or resource depletion it is therefore suggested to consider insights from transition studies more prominently in a policy framework that is based on the innovation systems approach and the associated notion of failures we propose a comprehensive framework that allows legitimizing and devising policies for transformative change that draws on a combination of market failures structural system failures and transformational system failures

normal markets market imperfections and energy efficiency abstract the conventional distinction between economic and engineering approaches to energy analysis obscures key methodological issues concerning the measurement of the costs and benefits of policies to promote the adoption of energy efficient technologies the engineering approach is in fact based upon firm economic foundations the principle of lifecycle cost minimization that arises directly from the theory of rational investment thus evidence that so called market barriers impede the adoption of cost effective energy efficient technologies implies the existence of market failures as defined in the context of microeconomic theory problems of imperfect information and bounded rationality on the part of consumers for example may lead real world outcomes to deviate from the dictates of efficient resource allocation a widely held contrary view that the engineering view lacks economic justification is based on the fallacy that markets are normally efficient

identifying barriers in the diffusion of renewable energy sources abstract rapid diffusion of renewable energy sources res in the electricity power sector is crucial if the eu wants to fulfill its 2050 co2 reduction commitments for this reason identifying and alleviating all barriers that hinder the development of res is necessary to the successful deployment of these technologies this paper discusses the main barriers in the diffusion of wind and photovoltaic pv solar power in the greek electricity sector by drawing on the literature of technological innovation systems and system functions furthermore we provide an explanation of the different diffusion rates between the two technologies inadequate financial resources low grid capacity delays in the issuance of building permits opposition from local communities to the construction of wind farms and the lack of a stable institutional framework are among the most important barriers that inhibit the diffusion of the wind and pv solar power the nature of the barriers identified in this study calls for policy intervention

initiating a sustained diffusion of wind power the role of public private partnerships in spain the literature on policy approaches for the market support of renewable electricity is dominated by narrow conceptualizations of policy referring mostly to direct instruments for economic feasibility such approaches often led to unsatisfactory explanations of diffusion results this is the case of wind power diffusion in spain the success of which is typically credited to the feed in tariff instrument this paper offers an alternative explanatory account for wind power diffusion in spain it is argued that diffusion can be explained by a less obvious policy of stimulating investments by means of public private partnerships ppps the three legal frameworks for economic feasibility applicable up to 2004 harbored high economic risks although projects could have high profitability because of generous investment subsidies up to mid 1990s most investments were based on ppps to address the risk perceptions of early investors fully private partnerships now dominate investments though ppps have not disappeared next to winning investors confidence the ppp policy led to an investment culture whereby partnership investments dominate by 2000 95 7 of the installed wind capacity was owned by partnerships and only 4 3 by individual companies partnerships invest in larger projects have ambitious investment plans and these lead to a high diffusion tempo

three is a crowd exploring the potential of crowdfunding for renewable energy in the netherlands there is a huge gap between demand and supply of finance for energy transitions and the financial and economic crisis have had a negative impact in the already meagre funds for transforming the energy system towards renewable sources in this paper we explore whether crowdfunding for renewable energy as a novel sociotechnical practice developed in a niche has the potential to break through and transform both the energy and the financial regimes utilising the multi level perspective theory we empirically investigate crowdfunding platforms linked to renewable electricity projects in the netherlands the main conclusion is that the volume of crowdfunding today is low but the dynamic of these projects holds potential there is limited indication of learning processes until now as well as limited support from regime actors pointing at a low level of niche stabilization and break through potential which may however be related to the early stage of development of crowdfunding in the netherlands on the other hand the heterogeneity of crowdfunders is very promising platforms dedicated to renewable electricity exclusively and with an investment based business model seem to be the most successful we show how governmental market regulation and support mechanisms are shaping crowdfunding as a business model and discuss the implications for other countries

the value of information in competitive bidding abstract we consider the situation where two players compete to obtain a valuable object e g a stand of timber in a competitive sealed bid environment prior to submitting a bid each player may sample the stand while incurring a common non zero cost for each observation on one hand a player wishes to take as few observations as possible due to the cost of collecting information however one also wishes to obtain as many observations as possible to avoid a bid that overstates the value of the resource given different assumptions on the sampling process the informational structure and underlying distribution of value we derive equilibrium bidding strategies we use these bidding strategies to solve for equilibrium in an information collection problem from the forest products industry

mobilizing private finance to drive an energy industrial revolution abstract while uptake of renewable energies as a solution to climate change is widely discussed the issue of public vs private financing is not yet adequately explored the debates over the kyoto protocol and its successor culminating in the cop15 climate change conference in copenhagen in december 2009 maintained a strong preference for public over private financing yet it is also clear to most observers that the energy revolution will never happen without the involvement of private finance to drive private investment in this viewpoint we discuss the ways in which private financing could be mobilized to drive the energy industrial revolution that is needed if climate change mitigation is to succeed

auctions with resale markets an application to u s forest service timber sales when bidders anticipate an opportunity for resale trade the value of winning an auction is determined in part by the option values of buying and selling in the secondary market one implication is that a bidder s willingness to pay at an auction increases with the expected level of competition between resale buyers empirical evidence from auctions of timber contracts supports this prediction and rejects standard models that ignore resale the estimated effect is smaller after policy changes expected to diminish the prevalence of resale additional evidence supports the predicted presence of a common value element introduced by the resale opportunity

understanding the shadow impacts of investment and divestment decisions adapting economic input output models to calculate biophysical factors of financial returns abstract in recognition of the cumulative effects resulting from financial decisions a growing number of campaigns are advocating for the removal of investment funds from companies responsible for high levels of carbon emissions a systematic approach can aid in examining the social economic and environmental impacts that extend beyond political motivations to divest from fossil fuel companies we have adapted publicly available economic input output life cycle assessment models eio lca to develop a shadow impact calculator sic for examining the potential environmental impacts of investment decisions an investment portfolio s shadow impacts represent the economic social and environmental effects underlying an investor s decision to place their funds in particular financial instruments in this study we focus on greenhouse gas emissions to show which sectors of the united states economy have particularly large or small carbon shadows and place those results in the context of volatility and earnings to demonstrate how sic may be used we examine the endowment investments of a canadian university in the context of divesting from fossil fuel companies our analysis suggests that large pooled funds choosing to direct their investments away from heavy carbon emitters may have less of an impact than would otherwise be expected

public policy influence on renewable energy investments a panel data study across oecd countries this paper examines the impact of public policy measures on renewable energy re investments in electricity generating capacity made by institutional investors using a novel combination of datasets and a longitudinal research design we investigate the influence of different policy measures in a sample of oecd countries to suggest an effective policy mix which could tackle failures in the market for clean energy the results call for technology specific policies which take into account actual market conditions and technology maturity to improve the conditions for institutional investments advisable policy instruments include economic and fiscal incentives such as feed in tariffs fit especially for less mature technologies additionally market based instruments such as greenhouse gas ghg emission trading systems for mature technologies should be included these policy measures directly impact the risk and return structure of re projects supplementing these with regulatory measures such as codes and standards e g rps and long term strategic planning could further strengthen the context for re investments

differentiated bids for voting and restricted voting shares in public tender offers abstract this paper develops a model for takeover bid premiums of voting and restricted voting shares when the bidder wants 100 of the target firm for this special case a higher bid premium may be offered either to the voting or to the restricted voting shareholders we also analyze consequences of the equal offer and one share one vote principles and investigate the model s explanatory power on swedish data

evolutionary approaches for sustainable innovation policies from niche to paradigm fostering technological innovation is considered as an important element of policies towards sustainable development in the past 10 years evolutionary policy approaches have been increasingly advocated for several reasons they seem well equipped to underpin sustainable innovation policies they focus on dynamics of change and their drivers they allow for a substantive perspective on technologies beyond mere input output relations taking into account trajectories and different characteristics of innovation and they are able to describe circumstances under which established technologies might persist even when they are to some extent inferior to their new competitors lock in however the policy effectiveness of evolutionary approaches in cases in which radical or systemic changes are involved is not yet proven in this paper we assess the theoretical rationale instrumental aspects and the coping with policy constraints of three evolutionary policy approaches which have also been used in empirical studies strategic niche management transition management and time strategies each approach has its strengths and specific problems and all three have to be further developed and tested out but they hold promise for contributing to non incremental change with economic and environmental benefits by shaping processes of variation selection and retention with the outcomes feeding back into policy they may also be used in other areas in which innovation direction is important for instance health care or food
