design and analysis of simulated consumer choice or allocation experiments an approach based on aggregate data the authors integrate concepts in conjoint analysis and discrete choice theory in econometrics to develop a new approach to the design and analysis of controlled consumer choice or resource allocat

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

cross hedging and forward contract pricing of electricity we consider the problem of an electric power marketer offering a fixed price forward contract to provide electricity that it purchases from a potentially volatile and unpredictable fledgling spot energy market one option for the risk averse marketer who wants to hedge against the spot price volatility is to engage in cross hedging to reduce the contract s profit variance and to determine the forward contract price as a risk adjusted price the sum of a baseline price and a risk premium we show how the marketer can estimate the spot price relationship between two wholesale energy markets for the purpose of cross hedging as well as the optimal hedge and the forward contract s baseline price and risk premium

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 money talk the effect of a monetary attribute on the marginal values in a choice experiment when designing choice experiments for nonmarket valuation the role of the price attribute is of major importance in the energy sector the uncertainty of future direction of changes in prices makes it difficult to include an adequate price vector in the design we separately investigate the implication of using price vectors with increases and decreases in tariffs from current levels on marginal value estimate from choice experiment data developed using prospect theory in addition we also analyse the effect of excluding the price vector on these marginal values by and large our results support the neoclassical theory as we find that the means of the conditional estimates of the marginal values of attributes are unaffected by the direction of the price change and from exclusion of the price attribute however the distributions show a larger spread of values when the choice experiment implies a tariff decrease which may have policy implications

evaluation of the importance of fisheries management objectives using choice experiments abstract fisheries management is characterised by multiple objectives decision making is often impeded by different stakeholders placing different importance on these objectives while compromise solutions are often achieved more efficient solutions might be possible if the preference structure of stakeholders was known in this paper the potential of choice modelling for evaluating the importance of potentially conflicting fisheries management objectives is examined the fisheries of the english channel are used as an example results from a survey of the key stakeholders in these fisheries are presented showing that regional employment and sustainable yields are of key concern overall the importance between objectives can be measured appropriately and the methodology can offer useful information to the management process

european schemes for promoting renewables in liberalised markets abstract the paper describes possibilities and problems for penetration of supply systems based on renewable energy sources in liberalised markets the analysis is based on recent development in eu with different models for support of installations based on renewable energy these include feed in models with guaranteed minimum tariffs tender models for different bands of technologies and green certificates trading models with obligatory consumer quota the paper describes the market situation in selected european countries including germany the uk holland and denmark an eu directive from september 2001 has postponed the decision on a possible harmonisation of promotional models until at least 2005 in order to obtain more practical experience with the different support schemes a critical evaluation is given in this paper of the different models with proposals for a balanced development between environmental and trading concerns it is argued that too much emphasis is presently given to the side of free trade at the expense of long range planning for a sustainable energy development

project finance and international energy development this paper explores the preference for and the features unique to project finance one of the favoured vehicles for funding energy development our main focus is on the interests of project sponsors commercial banks and host governments inclusion of the latter reflects the fact host governments are often leading participants in primary energy and energy related projects more recently they have come to use limited recourse structures to finance local infrastructure development traditional analyses whilst providing useful insights into the interests of leading project participants are incapable of isolating a single motive or set of motives that can comprehensively account for all of the features common to this form of debt within an options theoretic framework most of these ambiguities are resolved risk management long recognised as one of the primary reasons for choosing project finance over rival debt structures is affirmed as a key explanatory factor on the other hand options pricing theory provides a radically different perspective on how project finance contributes to the realisation of these objectives

the investor specific price of renewable energy project risk a choice experiment with incumbent utilities and institutional investors abstract renewable energy investments in germany have recently soared trebling the output of wind and solar power generation in only ten years while incumbent utilities have lagged behind in terms of investment new entrants have significantly contributed to this growth existing literature has primarily focused on explaining the lethargy of incumbents former investments although there is a growing need to investigate recent investment drivers to secure the necessary power plant capacity at a moderate cost from incumbents and new entrants alike to close this gap a choice experiment involving 1 659 investment choices by 52 european professional investors was conducted in significant contrast to the case with altruistic investors this survey underlines the importance of using financial incentives to attract professional investors given full exposure to electricity price risk incumbent utilities would facilitate projects at a 3 04 risk premium whereas institutional investors demand 6 61 generally incumbent utilities and institutional investors are equally attracted by low risk projects however when risk increases institutional investors are more hesitant to become involved while incumbent utilities confidently navigate these higher risk projects

capital budgeting technological innovation and the emerging competitive environment of the electric power industry abstract for most of this century the electric utility industry has operated as a regulated natural monopoly which produced a commodity product in an environment of low technological progress and sold it to a homogeneous captive market given these conditions the primary capital budgeting issues involved the timing of capacity additions and the mix of base load and peaking capacity this relatively simple and stable situation however has been eroded by market regulatory and technological changes as a consequence old embedded capital budgeting approaches are hindering the pursuit of efficiency with respect to the production and distribution of electric energy our purpose in this paper is to assess traditional utility capital budgeting procedures and to explore possibilities for improvement we begin with a review of traditional capital budgeting decision processes next we overview the changes that have emerged over the last two decades and explore capital budgeting processes more appropriate to this early competitive environment finally we project the changes a bit further and explore the capital budgeting techniques that may be useful in an advanced competitive environment

investment in competitive electricity scope for incentive contracts abstract there is considerable interest in investment in electric power but few projects have actually taken off the situation with investor owned plant is that recovery of the total costs of a new power station via tariffs in the usual way is not automatic the difficulty most often is that the investor and the host system or government need to negotiate on issues such as long term energy pricing the rate of return risk sharing and long term guarantees this paper argues that incentive contracts incorporating risk sharing parameters whose values are set to account for perceptions of risk magnitude and the degree of willingness to take risk are a promising approach to the problem the scope of incentive power contracts the spatial relationship between return and parameters and the methods of deciding parameter values are discussed

financing energy projects experience of the international finance corporation this paper provides an overview of the recent trend towards private ownership and financing of power projects in the developing countries focusing on the role played by both private and public agencies in meeting the large financing challenges the paper draws upon the operational experience of the international finance corporation which has been involved in the financing of more than 30 private power projects in the developing countries over the past three decades among the issues that affect implementation of private power projects is the balancing of risk and reward to equity investors and to commercial lenders the paper discusses the principal sources of risk and the strategies used to manage them a related issue is the competition for capital on the international markets and the techniques that are being devised to bring more finance to the power sector finally the paper considers the role of government in bringing private investors to the power sector and the approaches being adopted to balance the needs of investors with the needs of the public

biomass power exploring the diffusion challenges in spain the use of biomass resources for power generation offers numerous benefits of interest for political decision makers fuel security rural and industrial development ecological benefits in spain policy instruments have been used since 1980 to stimulate biomass power generation however the diffusion outcome by 2007 was very disappointing only 525 mw this paper argues that two factors lie at the core of this the conceptualization of biomass resources by political decision makers in the instruments used and the desire that policy instruments be in line with market liberalization principles these generated a persistent economic obstacle for biomass power generation and impeded the development of markets for the supply of biomass resources the policy learning regarding the heterogeneity of biomass resources and the investors expectations on risks profitability and resource markets was very slow among political decision makers the paper contributes to the understanding of diffusion outcomes by proposing to analyse diffusion by means of five indicators types of resources technologies developers motivations to invest and project sizes besides the paper shows the usefulness of investigating policy instruments in terms of their risk and profitability characteristics this enables a better understanding of the diffusion patterns and outcomes

motives to adopt renewable electricity technologies evidence from sweden the diffusion of renewable electricity technologies rets has to speed up for countries to reach their often ambitious targets for renewable energy generation this requires a large number of actors including individuals companies and other organizations to adopt rets policies will most likely be needed to induce adoption but there is limited knowledge about what motivates ret adoption the purpose of this paper is to complement and expand the available empirical evidence regarding motives to adopt rets through a survey to over 600 ret adopters in sweden the main finding of the study is that there are many different motives to adopt rets and that ret adopters are a heterogeneous group with regard to motives although environmental concerns interest in the technology access to an re resource and prospects to generate economic revenues are important motives in general adopters differ with regard to how large importance they attach to the same motive and each adopter can also have several different motives to adopt there are also differences in motives between adopter categories especially independent power producers vs individuals and diversified companies and between rets especially wind power vs solar power this implies that a variety of policy instruments might be needed to induce further adoption of a variety of rets by a variety of adopter categories

renewable energy certificate mechanism in india a preliminary assessment abstract the indian national action plan for climate change napcc envisages several measures to address global climate change one of the important measures identified involves increasing the share of renewable energy in total electricity consumption in the country this would mean napcc envisages renewable energy to constitute approximately 15 of the energy mix of india by 2020 to achieve the target set by the napcc indian ministry of power launched renewable energy certificate rec mechanism in november 2010 however participation in the rec markets is low and recs have failed to attract significant investment so far in this study a preliminary attempt has been made to assess the performance of existing rec mechanism in india after highlighting the salient features of the indian renewable energy policy framework a brief description of renewable purchase obligation rpo and source specific rpos for different states is discussed along with an overview of rec market in india to date the performance of indian rec mechanism is evaluated by cost competiveness decentralized distributed generation and renewable energy portfolio diversity and their effectiveness has also been measured on the basis of the available data although it is difficult to make any conclusive remark on the success or failure of rec mechanism due to its short experience this study examines the process to date to come out with some recommendations which can be used to fine tune the functioning of existing rec market in india for instance rec price bounds should be revised because it has been not explicitly supporting cost competiveness by offering 60 33 higher average price than the existing average feed in tariff fit it is also observed that state wise contribution in registered capacity is skewed towards few states like tamil nadu 27 maharashtra 23 and uttar pradesh 22 which puts pressure on policy makers to restructure the existing rec mechanism

the production tax credit for wind turbine powerplants is an ineffective incentive abstract the us energy policy act epact of 1992 created a production tax credit of 1 5 kwh available for 10 years to promote certain renewable energy technologies including wind turbines this paper argues that the impact of the wind turbine production tax credit will be minimal the argument depends entirely on the nature of the project finance structure used by the private power industry for wind turbine development we show that tax credits can only be absorbed by equity investors if there is a large fraction of equity in the project capital structure this raises the financing cost of wind turbine projects compared to conventional power technology which relies on a large fraction of low cost debt if the tax credit were paid as a cash subsidy the capital structure could be shifted to low cost debt and financing costs could be significantly reduced

a critique of renewables policy in the uk the contribution of renewables to the reduction of co2 emissions is hampered by the operation of neta in two ways by its reflection of the high balancing costs within the context of the existing generation and network capacity and the scarcity of long term contracts in traded markets the government s approach of imposing contracts through the renewables obligation is inferior to the development of a carbon tax and risks picking winners from existing technologies rather than exploiting the full range of options

emergent complexity in agent based computational economics abstract in this paper we shall review two kinds of emergent complexity in agent based computational economics ace the first kind is based on the complex systems initiated in the 1980s or even earlier by mathematicians and physicists whereas the second kind is based on the idea of complex adaptive systems composed of autonomous agents for which many representative works have been collected in rosser for the latter we shall go further to examine the two elements which have just recently been incorporated in agent based economic modelling namely intelligence and modularity this augmentation leads to the development of neurocognitive software agents which can guide the generation and direction of future ace studies with a multistage brain behaviour to emergency to brain behaviour approach

fixed feed in tariff versus premium a review of the current spanish system a b s t r a c t since 1998 the spanish government established a feed in system where res e generators could choose between two alternatives fixed feed in tariff and premium nowadays all res e 1 can be sold in the electricity market getting an additional premium except for solar photovoltaic one important novelty established in 2007 is a cap and floor system for facilities under the premium option the aim of this paper is to analyze and compare these two alternative options fixed fit and premiums which coexist at the same time in spain describe the evolution of both systems and evaluate its performance the introduction of this support system in spain led to very good results in terms of res e deployment the main advantage of the premium option is that it is a scheme integrated in the electricity market one disadvantage is that it can occasionally lead to overcompensation one way to try to avoid it is to set a cap value in order to evaluate the performance of this dual support system not only res e deployment has been assessed but also the policy stability the adequacy of res e production to the electricity demand pattern and the changes in the investors behaviour

iq and economic growth further augmentation of mankiw romer weil model abstract solow s growth model is further augmented to include iq in addition to proxies for education and health the estimates indicate that iq variable greatly erodes the size and significance of education and health parameters and dominates even a measure of institutional quality

iq in the production function evidence from immigrant earnings the cross country growth literature especially sala i martin 1997 sala i martin doppelhofer and miller 2004 has found that traditional education measures rarely have a robust relationship with growth and productivity elementary education being a rare exception by contrast a new empirical growth literature jones and schneider 2006 lynn and vanhanen 2002 ram 2007 weede 2004 weede and kampf 2002 has shown that a nation s average iq has a remarkably robust relationship with its productivity figure 1 that a test designed by psychologists should have such a robust relationship with economic variables is a puzzle that demands explanation for instance jones and schneider showed that national average iq was more robust than other human capital variables and was statistically significant at the 1 level in all 455 growth regressions that controlled for all 18 factors that passed sala i martin doppelhofer and miller s 2004 robustness tests of course as with all the growth regression literature a key difficulty is disentangling cause and effect thus in this article we run no growth regressions whatsoever instead we perform a simple calibration of the iq productivity relationship based on widely agreed upon microeconomic parameters that means we can directly estimate one causal channel running from cognitive ability to productivity in the process we learn the following 1 if one knows the average iq of a nation s citizens as estimated by lynn and vanhanen 2002 2006 one can predict the average wages that immigrants from that country will earn upon their arrival in the united states whether or not one controls for immigrant education and even if the test is completely visual rather than verbal in other words national average iq predicts part of what hendricks 2002 calls unmeasured worker skill 2 we find that a 1 point increase in national average iq predicts 1 higher immigrant wages precisely the value found repeatedly in microeconometric studies note that by construction 1 iq point approximately equal to 1 15th of a standard deviation within any large national population together points 1 and 2 provide further evidence that cross country iq tests are valid predictors of worker productivity 3 when iq is added to the production function in the form implied by traditional externality free human capital theory differences in national average iq are quantitatively significant in explaining cross country income differences that said our productivity accounting exercise does not resolve the puzzle of why high iq countries are 15 times richer than low iq countries in a related vein hanushek and kimko 2000 use national math and science test scores to verify that cognitive skills appear to matter more for groups than for individuals like us they use immigrants to the united states as a way to test whether immigrants bring their home country productivity levels along with them when they immigrate to the united states when they interpret their results within a solow type framework they conclude that the cross country growth equation results are much larger than the corresponding results for individual earnings in sum our article rigorously explores the quantitative magnitude of the puzzle uncovered by hanushek and kimko 2000 and hanushek and woessman 2007 but by using iq tests rather than other widely used math and science test scores we can often double our sample size while simultaneously using the most widely analyzed best understood form of cognitive test we begin with an overview of the recent psychological literature on the validity of iq tests and then proceed to our discussion of the link between iq and immigrant wages the discussion of iq and immigrant wages yields a key parameter gamma the iq semi elasticity of wages which we use in our development accounting exercise we then discuss the questions of reverse causality and trends in the iq productivity relationship over the past 40 yr and conclude by discussing how our results fit into the growth literature

the renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

policies to accelerate the growth of offshore wind energy sector in india abstract india s power generation capacity needs to be augmented to support the growing demands for electricity india which has predominantly used fossil fuels to power its generators need to make a switch to clean energy fuels but renewable sources form a miniscule portion 26 gw 12 of india s overall installed power capacity 210 gw there is no contribution from offshore wind farms to the energy basket for india as there is no policy framework to encourage the development of offshore wind farms several european countries have tapped the offshore wind energy potential to reduce their dependence on adopted by these countries to identify the core components 21 of them of robust policy intervention a detailed questionnaire was administered to 181 stakeholders of wind energy in india to seek their feedback on these building blocks these core components variables in research parlance are then subjected to factor analysis to understand the underlying structure of the variables the factor analysis logically reduces these 21 variables into five factors government support fiscal and quota based incentives availability of local expertise capital for investments and building an enabling r d ecosystem which are then fed into a logistic regression model as independent variables to predict the probability of growth of offshore wind energy dependent variable in the country the logistic regression model gives the weight the impact of these independent variables in influencing the growth of offshore wind energy in india it emerges that government support fiscal and quota based incentives and building an enabling r d ecosystem have a much higher impact on the growth of offshore wind energy for india this paper fills the gap of absence of an empirically tested framework on offshore wind energy policy for india

new directions in electric power financing this paper argues that it is necessary to raise the eyes from the current focus on independent power projects buttressed by guarantees to the longer horizon of electric power financing in open markets transitional strategies will need to move beyond the commonly seen ipp activity that occurs without fundamental sector reform and demand side incentives that introduce further market distortions these efforts will have to focus on macroeconomic stabilization removal of price distortions as well as sector and corporate reform mobilization of domestic capital will be essential for sustainable sector financing although guarantees to encourage power sector investment can be designed to selectively cover risks their elimination through fundamental sector reform should be the ultimate goal over the longer term traditional corporate finance should become a more common financing strategy than project finance innovations in performance risk management and consumer credit will be crucial to the financing of energy efficiency

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

socio technical analysis of the electricity sector of mexico its historical evolution and implications for a transition towards low carbon development abstract the electricity sector of mexico has been found itself in continuous transitions since its beginning in the 19th century however the historical reform to the sector that recently took place together with new energy market configurations around the globe may pose an important challenge to transitioning towards a low carbon sector the work presented here was aimed at understanding in a qualitative manner the complex interactions between the main social technical and environmental aspects that have guided the sector in the past their influence on the current structure and its future development through the application of the multi level perspective mlp with a governance and agency perspective additionally the work tried to elucidate the implications of the incumbent position of the natural gas industry and the possibilities for low carbon technologies the conclusions remark the importance of previous sector configurations in the present structure the important role of government in promoting low carbon technologies together with investment by market actors and the possible window of opportunity that the natural gas industry in mexico may provide to low carbon energy technologies

property rights regimes in complex fishery management systems a choice experiment application the tonle sap wetland fishery was previously divided into 3 different management zones for conservation open access fishing and private fishing rights to the private fishing zone involved auctions for exclusive rights to temporarily designated plots this paper aims to explore the auction based system by investigating how this fishery management system affects different groups of small scale fishermen and how different characteristics of the fishing lots affect the bidding a choice experiment approach was used to model fishermen s choices in a hypothetical auction market by offering fishermen the choice between purchasing different potential fishing lots and a no purchase option implying fishing only in the communal fishing grounds the preferred latent class model with two segments of fishermen showed that the bidding behavior of the more privileged group out competes the other group irrespective of the lot characteristics this result suggests that it is unlikely that the redesign of the auction system itself would be an effective way of securing access to fishing resources for the two observed groups of fishermen this implies that open access fishing grounds and or other regulations may also be needed in future management as they serve an important role for the poorer segments

the financing of the mexican electrical sector abstract this paper analyses the financial pattern of the mexican electricity sector its financial limits in both development and modernization of this strategic sector and the main options for resolving this financing problem including the proposals of the president fox government our allocation of risks and profitability analysis explain the present success in attracting private investments to expand both generation and transmission capacity through blt and ipp projects the financial limitation is nevertheless the low self financing of federal electricity commission cfe that will make it very difficult to obtain financing to fulfil blt and ipp contract compromises and to invest large sums in the expansion and modernization of the electricity sector the main options to resolve the financial problems of the mexican electricity sector are 1 the improvement of the present financial pattern 2 the opening of generation and supply segments to private capital with the preservation of the vertically integrated state owned utilities and 3 the proposals of the president fox economic transition team that consider the opening of generation and supply segments the setting up of an independent state owned company to operate both the electrical dispatching and a power pool and finally the transformation of cfe into a holding of state owned utilities of generation distribution and transmission

financial risks for green electricity investors and producers in a tradable green certificate market this paper analyzes financial risks in a market for tradable green certificates tgc from two perspectives existing renewable producers and potential investors in new renewable electricity generation capacity the equilibrium pricing mechanism for a consumer based tgc market is described and a market with wind turbines as the sole renewable technology is analyzed in this framework tgc prices and fluctuations in production from wind turbines will be negatively correlated and as a result tgc price fluctuations can actually help decrease the total financial risk based on this recognition analytical expressions for revenue variance minimizing trading strategies are derived and an analysis of the demand and supply for financial hedging is used to show that forward contracts will be traded at a risk premium

the mexican electricity sector policy analysis and reform 1992 2009 this article analyses the cause effect relation of the structural reform in the mexican electricity sector called the public electricity service act from 1992 to 2009 one of the main arguments of the reform is to attract private investment in order to reduce the financial load of the government in infrastructure for the development of the national electric power system by means of six modalities power self supply cogeneration small power production independent power production power export and power import the article presents the global context of reforms adopted in 1990 the major policies and events are presented in chronological order before and after reform in addition it analyses the new institutional framework the evolution of modalities technologies of electricity generation and tariffs the main conclusion is that the result of reform could be considered a partial progress the independent power production modality shows greater participation while power self supply and cogeneration are lower the subsidy policy is maintained progress is needed in policies and strengthening and also in updating regulatory and normative frameworks

small streams diverse sources who invests in renewable energy in finland during the financial downturn this article addresses the investment gap in renewable energy sources identified by several authors examining the case of a country finland which introduced policy measures to diversify its renewable energy portfolio we analyse the development of investments in renewable heat and power in response to new policy measures and contextual factors during the downturn period 2009 2013 we investigate investor heterogeneity i e the diversity of logics employed by different types of res investors in spite of a severe financial recession we find an emergence of new sources of investment among these new investor types we find diversity in investment drivers and available options these include investors mobilized by the feed in tariff to seek profitable targets and investors such as real estate owners investing in heat pumps for their own use and benefiting from low interest rates we find that the diversification of investors supports the diversification in res sources and brings in new investors undeterred by the financial downturn our findings imply that policy makers should recognize that the responses to distinct incentives and pressures vary by investor types this also means that a mix of policies is required to maximize the contribution of different sectors to filling the renewable energy investment gap

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

avoided cost contracts can undermine least cost planning abstract utilities and regulatory agencies are increasingly turning to non utility sources of electric power in the usa many contracts with independent power producers ipps contain indexing terms under which an ipp s energy rates vary in response to energy cost changes on the purchasing utility system such indexing is often used to ensure that ipp rates track utility avoided costs unfortunately such indexing can undermine least cost planning if utility decisions can alter established ipp rates such indexing can also cause ratepayer interests to conflict with those of society the use of regional cost indices can solve the utility planning problem preventing the conflict between ratepayers and society however may require some use of cost based rather than value based ratemaking for ipps

health capital and cross country variation in income per capita in the mankiw romer weil model abstract this paper examines the effects of incorporating a proxy for health capital in mankiw romer and weil s empirical growth model results suggest a stronger and more robust relationship between income per capita and health capital than between income per capita and educational human capital

investigating fishers preferences for the design of marine payments for environmental services schemes we determine the effects of various management restrictions on adoption rates of marine payments for environmental services pes schemes choice experiments are used in order to determine how fisher participation rates change under different marine pes programme designs various designs with differing restriction rates show different rates of adoption however fishers show a high utility loss associated with any move away from the current management situation irrespective of restriction levels this indicates that pes scheme costs may be high and creating an enabling environment could be important to reducing perceived losses as could investment into conditional in kind compensation mechanisms the paper also shows choice experiments to be a useful tool in marine pes design

deregulation and restructuring of the global electricity supply industry and its impact upon power plant suppliers abstract this paper analyses the deregulation and restructuring of the global electricity supply industry and its impact upon fuel usage generation technologies and suppliers of power plant deregulation encouraged the growth of new independent power producers whose business requirements transformed the power plant industry the plant suppliers had to develop new capabilities and services to compete in the global market economies of scale and scope became crucial given the cost of developing the new technologies and providing the services required by the operators this led to the global consolidation of the power plant industry because only large integrated power engineering companies had the necessary resources and capabilities to compete in the new global environment

fair trade and harmonization of climate change policies in europe abstract in march 2000 the european commission presented a green paper on greenhouse gas emissions trading within europe supporting implementation of a community wide scheme in which the design and regulation of all essential elements would be harmonized at the community level the present paper analyzes economic arguments used to justify such a coordinated scenario showing these arguments to be based on misleading rhetoric about fair trade and harmonization diverse allocations of emissions allowances across member states are justified in theory in practice too no empirical evidence or model based results demonstrate that an uncoordinated european trading scheme would adversely affect competitiveness to any significant extent or substantially increase industrial relocations

the effect of financial constraints technological progress and long term contracts on tradable green certificates tradable green certificates tgcs have recently become a diffuse instrument to support renewable electricity in oecd countries although it is perhaps too early to draw a conclusive judgement on the effectiveness of this instrument in increasing renewable capacity and decreasing the price of certificates one view in the literature maintains that long term contracts are of particular importance for tgcs to be effective this paper contributes to this debate by analysing how financial constraints and technological progress can induce investors to hold pessimistic expectations of their ability to sell green certificates and still make a profit clearly these expectations will prevent investors from building new capacity to fulfil the quota comprised in tgcs and will keep the price of certificates traded in the market high as this kind of expectation is not influenced by most design features of tgcs one can conclude that long term contracts are particularly important in determining the effectiveness and cost effectiveness of these instruments some attention should therefore be paid to the features of the tgcs which induce obliged parties to offer long term contracts to renewable generators

designing choice sets for stated preference methods the effects of complexity on choice consistency abstract we vary the complexity of choice sets used in stated preference methods to evaluate the impact on choice consistency we define five measures of complexity that capture either the amount of information or the correlational structure of information in a choice set using these measures as randomly assigned treatments in a large experiment we analyze the consistency of respondents choices using a heteroskedastic multinomial logit model we find that i all of our measures of choice set complexity affect choice consistency ii changes in the correlational structure of information have the largest impact on choice consistency and iii choice complexity significantly distorts welfare estimates our results confirm economists initial worry that moving from contingent valuation to conjoint methods will increase complexity induced choice inconsistency however our analysis also shows that these negative impacts may be mitigated if precautions are taken at the design and estimation stages of stated preference methods

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

financing the energy sector in developing countries context and overview abstract traditional business as usual financing methods will no longer be adequate to meet the unprecedented demands for capital to finance energy sector expansion in the developing countries in recognition many countries are opening up their power sectors to private investment initially through the establishment of independent power projects but in some cases through sector privatization project financing has many advantages but further sectoral reorganization including tariff reform will be needed to attract resources on the scale required especially from domestic investors in oil and gas in contrast to power private capital from the international oil companies has always played a major role in the developing countries however sharply increasing investment requirements require a growing role for external finance there should in principle be no shortage of investible funds to finance energy sector expansion in developing countries so long as host countries establish conditions which are attractive to private investors the augmented role of private finance requires a continuing if different role for the public sector in both host countries and official aid agencies

are entrepreneurship and cognitive skills related some international evidence do national differences in cognitive skills cs predict a nation s likelihood of generating high quality entrepreneurs who create and expand high value businesses we answer this question by estimating cross country regressions that use the acs and szerb global entrepreneurship development index gedi and a measure of national cs after including conventional controls we find for a sample of 60 countries that our measure of cs robustly predicts the gedi unconditional correlation 0 65 standardized beta 0 42 an index that gives weight to both entrepreneurial attitudes within a nation and the institutional and economic prerequisites for creating high value high growth firms we find that this result also holds for an alternative measure of entrepreneurship

assessment of current dutch energy transition policy instruments for the existing housing stock abstract this research assesses to what extent current dutch energy transition policy instruments for the existing housing stock can fulfil local executive actors needs and instigate adoption of energy efficiency measures by them this is done by studying energy policy instruments for the existing housing stock in the netherlands and in other european countries and by an empirical research which analyses barriers and needs of local executive actors we found that despite current dutch energy transition policy instruments for the existing housing stock seem to fulfil local executive actors needs to a large extent complementary policy instruments are needed to stimulate and pressure the incumbent renovation regime a long term oriented financial rewarding system is needed to build up a structural market for the deployment of renewables to increase the number of specialist jobs in the building sector and to stimulate the development of integrated standardized building components furthermore a long term oriented financial rewarding system for energy efficiency investments in housing renovation projects and a low vat rate applied to energy efficient renovation measures are needed finally enforcement possibilities and sanctions fines should become an integrative part of dutch energy certification regulation to make the certificate become part of a value chain

real world performance of choice based conjoint models conjoint analysis is one of the most important tools to support product development pricing and positioning decisions in management practice for this purpose various models have been developed it is widely accepted that models that take consumer heterogeneity into account outperform aggregate models in terms of hold out tasks the aim of our study is to investigate empirically whether predictions of choice based conjoint models which incorporate heterogeneity can successfully be generalized to a whole market to date no studies exist that examine the real world performance of choice based conjoint models by use of aggregate scanner panel data our analysis is based on four commercial choice based conjoint pricing studies including a total of 43 stock keeping units sku and the corresponding weekly scanning data for approximately two years an aggregate model serves as a benchmark for the performance of two models that take heterogeneity into account hierarchical bayes and latent class our empirical analysis demonstrates that in contrast to the performance using hold out tasks the real world performance of hierarchical bayes and latent class is similar to the performance of the aggregate model our results indicate that heterogeneity cannot be generalized to a whole market and suggest that aggregate models are sufficient to predict market shares author s abstract

a comparison of stated preference methods for environmental valuation this paper presents an empirical comparison of contingent valuation cvm and choice experiments which are used to value environmental quality changes both of these methods require individuals to state their preferences for environmental qualities however choice experiments differ from cvm in that environmental attributes are varied in an experimental design which requires respondents to make repeated choices between bundles of attributes the empirical application involved the effect of environmental quality changes arising from forest management practices on recreational moose hunting values significant differences were found between the values derived from the two methods however detailed examination of the implied choice behaviour suggested that respondents ignored substitute recreation areas in the cvm question restricting the choice experiment model to consider only the one site where quality was varied resulted in welfare estimates similar to the cvm model this highlights the importance of substitutes in environmental valuation and suggests that choice experiments may be more appropriate than cvm in some cases
