analysing the interactions between renewable energy promotion and energy efficiency support schemes the impact of different instruments and design elements abstract co2 emissions reduction renewable energy deployment and energy efficiency are three main energy environmental goals particularly in europe their relevance has led to the implementation of support schemes in these realms their coexistence may lead to overlaps synergies and conflicts between them the aim of this paper is to analyse the interactions between energy efficiency measures and renewable energy promotion whereas previous analyses have focused on the interactions between emissions trading schemes ets and energy efficiency measures and ets and renewable energy promotion schemes furthermore the analysis in this paper transcends the certificate debate i e tradable green and white certificates and considers other instruments particularly feed in tariffs for renewable electricity the goal is to identify positive and negative interactions between energy efficiency and renewable electricity promotion and to assess whether the choice of specific instruments and design elements within those instruments affects the results of the interactions

international scientist mobility and the locus of knowledge and technology transfer abstract despite the growing interest of scholars and policymakers to better understand the determinants for researchers in public science to transfer knowledge and technology to firms little is known how temporary international mobility of scientists affects both their propensity to engage in knowledge and technology transfer ktt as well as the locus of such transfer based on a sample of more than 950 german academics from science and engineering faculties we investigate how the duration and the frequency of scientists visits at research institutions outside their home country affect ktt activities we find that most mobile scientists engage in ktt to firms both in the host and in their home country suggesting that ktt activities to firms abroad do not substitute or crowd out but complement ktt to firms in the home country we further find that the longer research visits abroad are the higher the likelihood that scientists engage in ktt to firms again both in the host and the home country however the more frequently scientists visit institutions abroad the more likely they are to engage in ktt to firms only in their home country our results therefore provide evidence for the benefits of brain circulation the article contributes to the growing strand of the literature on scientist mobility and on the determinants of industry science linkages at the individual level

the impact of institutional and social context on corporate environmental social and governance performance of companies committed to voluntary corporate social responsibility initiatives abstract using a neo institutional framework this paper discusses the role of national specific social cultural legal regulatory and economic differences when determining the way that companies committed to a specific voluntary corporate social responsibility csr initiative operate in different sustainability dimensions the differences between companies environmental social and governance esg performance of the companies operating in the three countries with highest number of firms committed to the united nations global compact ungc spain france and japan is assessed through a multidimensional hj biplot technique which is a statistical technique that provides a joint graphical representation in a low dimensional euclidean space usually a plane of a multivariate data matrix this research contributes to the existing literature providing quantitative evidence of how different country specific social and institutional schemes influence companies esg performance the main results reveal the existence of two clusters of companies behaving in different ways with regard of sustainability issues first spanish and french companies exhibit similar levels of social and corporate governance performance higher than those of japanese firms second japanese firms seem more committed to environmental issues than spanish and french companies these results confirm that the different countries with different institutional backgrounds induce different priorities among their firms in terms of esg performance even under a common commitment to the same principles of adopted csr initiative

using a policy mix for pollution control a review of economic literature this article provides a review of economic studies analyzing the use of multiple policies a socalled policy mix to cope with single pollution problems to guide and structure the review an analytical framework is developed and applied the framework integrates transaction costs into the analysis of pollution problems and policies to overcome them moreover it understands a pollution externality not only as a market failure but more generally as the failure of private governance structures based on this insight two rationales for using a policy mix are identified first a policy mix may help to correct for multiple reinforcing failures of private governance structures such as pollution externalities and technological spillovers second a policy mix can be employed if the implementation of single first best policies brings about high transaction costs e g when marginal pollution damages are heterogeneous or polluters are unlikely to comply with the policy for each rationale the relevant literature is presented based on the review avenues for future research are identified

does foreign environmental policy influence domestic innovation evidence from the wind industry this paper analyses the relative influence of domestic and foreign demand pull policies in wind power across oecd countries on the rate of innovation in this technology we use annual wind power generation to capture the stringency of the portfolio of demand pull policies in place e g guaranteed tariffs investment and production tax credits and patent data as an indicator of innovation activity we find that wind technology improvements respond positively to policies both home and abroad but the marginal effect of domestic policies is 12 times greater the influence of foreign polices is reduced by barriers to technology diffusion in particular lax intellectual property rights reducing such barriers therefore constitutes a powerful policy leverage for boosting environmental innovation globally

subsidy and networking the effects of direct and indirect support programs of the cluster policy abstract industrial clusters have attracted considerable attention worldwide for their expected contribution to regional innovation recently policymakers in various countries have developed specific cluster policies however there exist few empirical studies on cluster policies focusing on the industrial cluster project icp in japan initiated by the ministry of economy trade and industry in 2001 we address two research questions on the support programs of the cluster policies if the project participants who exploit various support programs are more successful in network formation within the cluster than others and which kind of support program contributes to firm performance we pay special attention to the differences between direct rd firms should therefore select the program that is most aligned with their aims indirect support programs have an extensive and strong impact on output whereas direct r d support has only a weak effect

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

demand pull technology push and government led incentives for non incremental technical change abstract rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations how well does this notion of demand pull apply to non incremental technological change when demand is largely attributable to actions by governments in this case inventors of the most important inventions did not respond positively to strong demand pull policies filing of highly cited patents declined precipitously just as demand for wind power created a multi billion dollar market three explanations for this apparent inconsistency with the demand pull hypothesis played a role 1 the rapid convergence on a single dominant design limited the market opportunity for non incremental technical improvements 2 even though the policies implemented were stringent enough to stimulate demand uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off and 3 alternative explanations such as declining r d funding and weakening presidential engagement on energy appear to have been important

the information content of current cost income relative to dividends and historical cost income in september 1979 the financial accounting standards board fasb issued statement no 33 financial reporting and changing prices one of the items required by this statement is current cost income from continuing operations ccifco this item is considered by the fasb to be useful in assessing distributable income that is the amount of cash that may be distributed without reducing the operating capability of an enterprise sfas no 33 para 124 in essence a current cost income measure is claimed to remove the illusory inflation profit component and as such is potentially a better indicator of dividend paying ability evidence also exists that current dividends have information content which is consistent with the notion that they provide information on future income and dividends see for example pettit 1972 1976 griffin 1976 and aharony and swary 1980 however dividends are somewhat discretionary in which case ccifco may provide a basis for determining which dividend signals have implications for firm value and which do not since the accounting profession is currently in the process of assessing the desirability of continued disclosure of current cost information it

demand and innovation schmookler re examined schmookler s demand pull hypothesis implying that innovation is a function of market demand has been widely accepted re reading schmookler s invention and economic growth we discover a statistical inadequacy re estimating his cross section results in a different way we find somewhat lower coefficients moreover the direction of causality appears to be far from obvious an independent cross sectional test of the schmookler hypothesis in the netherlands based on r d instead of patent data shows similar results the relationship between indicators of demand and innovation turns out to be generally weaker but in most cases still significant and the results suggest that there is a simultaneous relationship between demand and innovation the latter may be explained by the concept of the innovation multiplier which has implications for macro economic modelling 1 re reading schmookler schmookler s 13 finding of a strong relationship between investment in capital goods users industries and patent applications by capital goods producing sectors has been generally accepted by economists as evidence that patenting is a function of effective demand demand pull hypothesis quite a number of case studies have followed schmookier s seminal work but there have been

firm incentives to promote technological change in pollution control reply abstract the process of technological change in pollution control is broken into three basic steps innovation diffusion and optimal agency response firm incentives to promote these steps are then examined under five regulatory regimes direct controls emission subsidies emission taxes free marketable permits and auctioned marketable permits on a relative basis emission taxes and auctioned permits provide the highest firm incentives to promote technological change at times free permits generate lower incentives direct controls which are common regulatory tools usually provide the lowest relative firm incentives to promote technological change

incentives and uncertainty an empirical analysis of the impact of demand on innovation we study the impact of demand on innovation by focusing on a sample of small and medium sized enterprises in several industries and european countries we analyse how demand stimulates innovation by providing economic incentives and reducing uncertainty considering the size of the market as a proxy for the presence of demand we find support for the idea that the presence of incentives stimulates innovation this is particularly true for process innovation in considering interaction with customers as a way to reduce uncertainty we find that firms that see customers as the most important sources of information for both innovation ideas and completion tend to introduce product innovations firm size r d expenditure and sectoral effects also matter

corporate social responsibility theories mapping the territory the corporate social responsibility csr field presents not only a landscape of theories but also a proliferation of approaches which are controversial complex and unclear this article tries to clarify the sit uation mapping the territory by classifying the main csr theories and related approaches in four groups 1 instrumental theories in which the corporation is seen as only an instrument for wealth creation and its social activities are only a means to achieve economic results 2 political theories which concern themselves with the power of corporations in society and a responsible use of this power in the political arena 3 integrative theories in which the corporation is focused on the satisfaction of social demands and 4 ethical theories based on ethical responsibilities of corporations to society in practice each csr theory presents four dimensions related to profits political performance social demands and ethical values the findings suggest the necessity to develop a new theory on the business and society relationship which should integrate these four dimensions

danish and norwegian wind industry the relationship between policy instruments innovation and diffusion this article compares the role of policy instruments in stimulating long term technological change in danish and norwegian wind industry it concludes that although predictability has periodically been low denmark s broad portfolio of policies and measures has been well adapted to the different stages in the development of its wind industry this has contributed to a high degree of innovation successful establishment in niche markets high degree of diffusion and establishment of domestic and international mass markets and in recent years an increasingly successful replacement of senescent technology with new the motivation of norway s wind energy policies and measures at least up until the late 1990s has been to increase power supply rather than to stimulate industrial development and technological change policies and measures have been weaker than in denmark have been less stable over time and stimulated the demand side much less they have not sufficiently covered the wind industry s perceived needs on different stages in the development of new technology and have not sufficiently stimulated continuous improvement learning and new product development dynamic efficiency in industry this has been part of the reason why there has been only a limited extent of innovation and diffusion of wind technology in norway

the impact of replacement cost disclosure on security prices new evidence abstract a number of studies have tested for information content in the asr 190 disclosure by comparing the conditional and unconditional distribution of abnormal security returns around the time of disclosure since no differences were observed it was concluded that asr 190 had no information content the study reported below performs a similar test by estimating the regression function of the conditional distribution of abnormal returns this test procedure controls for the information content in contemporaneous historical cost disclosure and uses a conditioning variable not considered in earlier tests it finds statistically significant stock price effects however because most of the effects appear to precede the official announcement date by several months it is unclear whether stock prices were responding to the leakage of the information content of asr 190 prior to disclosure to private production of information contained in asr 190 or to a variable omitted from the study which happens to be correlated with replacement costs

when does it pay to be good a contingency perspective on corporate social and financial performance would it work abstract the findings on corporate social and financial performance research has exposed the universal approach as tenuous and questionable so the current approach of corporate social and financial performance research has been subject to severe criticism instead of exploring a universal corporate social and financial performance link scholars have called for a contingency perspective in order to determine the conditions and context that catalyzes positive connections between the constructs this study systematically reviews the literature on the moderators exploited in corporate social and financial performance research and finds by and large that a positive corporate social and financial performance association dominates although the relationship is stronger in advanced economies and institutionalized contexts although research on the contingency perspective has progressed theoretical support for this relationship is thin and the lack of appropriate research design and stereotyped constructs thwart its positive implications a review of the literature shows that although organizational factors seem to moderating the corporate social and financial performance relationship strongly yet industry and country factors also tend to affect this association important consistencies included that a dynamic business environment reinforces the corporate social and financial performance relationship differentiation in social responsibility practices moderates the responsibility performance link but not often positively the effect of r d intensity is equivocal and advertising intensity did not strengthen this relationship across the level avenues for future research conclude our discussion

is public r d a complement or substitute for private r d a review of the econometric evidence is public r d spending complementary and thus additional to private r d spending or does it substitute for and tend to crowd out private r d conflicting answers are given to this question we survey the body of available econometric evidence accumulated over the past 35 years a framework for analysis of the problem is developed to help organize and summarize the findings of econometric studies based on time series and cross section data from various levels of aggregation laboratory firm industry country the findings overall are ambivalent and the existing literature as a whole is subject to the criticism that the nature of the experiment s that the investigators envisage is not adequately specified we conclude by offering suggestions for improving future empirical research on this issue

rationales for technology specific res support and their relevance for german policy in order to achieve cost effective res e deployment it is often argued that technology neutral support schemes for renewables are indispensable against this background res e support policies making widely use of technology differentiation in remuneration settings e g across the eu are frequently criticized from a theoretical point of view however in this paper we provide a systematic critique of the technology neutrality concept as a foundation for designing policy support schemes in the res e technology field specifically the main objective of the paper is to scrutinize the arguments for technology neutrality and discuss three conceptual arguments for why technology specific support schemes could in fact help minimize the societal costs of reaching future res e targets we also briefly address different political economy concerns which could constrain the choice of cost effective policy support schemes and that have to be taken into account for economic policy advice for empirical illustration of the key arguments we refer to the case of german res e policy making the central conclusion from this paper is that technology specific res e support schemes may generate significant economic benefits particularly if technology markets work imperfectly and in second best policy settings with additional non internalized market failures

a model of cultural differences and international alliance performance we propose a model of cultural differences and international alliance performance to explain the ambiguous findings regarding the influence of national culture differences on alliance performance building on research on national organizational and professional cultures we argue that the closer the domain of a social group is to the value creating activities of an alliance the more disruptive cultural differences between the partners members of that social group will be organizational culture differences will tend to be more disruptive than national culture differences and differences in the professional culture most relevant to alliance value creation typically will be the most disruptive implications for research and managerial practice are discussed and the model s relevance for international r d alliances is highlighted

supply and demand factors of cleaner technologies some empirical evidence this article identifies and analyzes factors that affect the willingness of firms and consumers to develop and adopt cleaner technologies cleaner technologies is used as a general term for pollution abatement technologies re use systems and environmentally sound consumer products and materials the article also contains the findings of three case studies on cleaner technologies cfc substitutes low solvent paints and coatings and membrane technology in which the importance of the identified factors is investigated from the case studies some general conclusions are drawn about these factors and the way in which policy instruments can be used to stimulate innovation in and diffusion of cleaner technologies no single policy instrument is considered to be optimal instead a policy mix is needed involving a much wider use of economic instruments

the influence of market demand upon innovation a critical review of some recent empirical studies abstract a number of recent empirical studies of technical change at the level of the individual firm have concluded that market demand is the dominant influence upon the innovation process calling forth innovations in market economies the pace of innovation in the private sector heavily influences the growth of national output and productivity and these studies and their conclusions have therefore received much attention having been extensively quoted in discussions of appropriate government policy for the encouragement of innovation this paper reviews a number of these studies and concludes that their findings and the interpretations of their findings in the secondary literature are seriously flawed and in many cases invalid the proposition that market demand governs the innovation process is by no means conclusively demonstrated in these studies and they are therefore inadequate and inappropriate guides for the formulation of policy most of the studies examined employ a working definition of demand factors which is so broad as to embrace a range of possible influences upon innovation which should more properly be classified elsewhere the concept of demand utilized in these studies bears little resemblance to the more restrictive and precise definition of market demand found in economics in addition the phenomena analyzed in these studies are a very heterogeneous lot the studies do not address identical empirical questions and their findings are as a result neither uniform nor unambiguous both demand and supply side influences are crucial to understanding the innovation process and it is the exclusive preoccupation with only one set of these forces which is criticized in this paper some implications of the criticism for government policy toward innovation are discussed in the conclusion

determinants of corporate social disclosure in spanish local governments this paper contributes to previous country level analyses of non financial reporting in the public sector by studying public transparency in relation to sustainability as well as by assessing the determinants of sustainability disclosure practices in spanish municipalities we have carried out a content analysis of the websites of 102 spanish local governments subsequently we have employed different statistical techniques biplots and dependence models to analyse the extent of disclosure and to determine the impact of certain contextual and political factors on transparency in matters of sustainability when compared to the amount of information that is revealed concerning financial issues disclosure practices regarding social and environmental information are rather scarce we have also observed that several political factors more specifically the presence of conservative governments and political rivalry may become genuine barriers to municipal transparency based on these findings we can make two policy recommendations first it seems necessary to establish national policies laws or recommendations that generate similar levels of transparency among local governments in order to avoid social dilemmas in this sense similar accountability processes limit non sustainable behaviours playing a similar role to that of markets for the private sector second accountability processes should focus on the addition of information concerning social and environmental actions and on informing of the effects of municipalities on them going beyond the strictly economic dimension

evidence on income measurement properties of asr no 190 and sfas no 33 data a number of studies have tested the association between security returns or levels of market value and current cost accounting data as reported under sec accounting series release no 190 asr 190 and statement of financial accounting standards no 33 sfas 33 for example beaver griffin and landsman 1982 henceforth bgl beaver and landsman 1983 henceforth bl and olsen 1985 found no association while bublitz frecka and mckeown 1985 henceforth bfm and murdoch 1986 found a weak association 1 in this paper we estimate cross section regressions of security returns on historical cost net income and holding gains as was done previously but with several extensions first we define our variables in terms of realizations of returns income and holding gains rather than in terms of unexpected changes thus we

assessing policy strategies for the promotion of environmental technologies a review of india s national solar mission abstract there is widespread consensus that no individual policy instrument but rather a policy mix is needed to effectively drive the development and diffusion of environmental technologies however what exactly constitutes such a policy mix remains largely undefined this paper takes this discussion a step further by developing a comprehensive framework for assessing and comparing policy approaches for the promotion of environmental technologies it begins with a critical review of existing policy mix concepts pointing out key shortcomings to address the identified challenges it proposes the concept of a policy strategy as an alternative framework for policy assessment and comparison this serves as the basis for integrating findings from the literature on environmental innovation and technological change in a comprehensive framework for assessing policy strategies for the promotion of environmental technologies the framework is then applied for the assessment of india s national solar mission the country s strategy for promoting solar energy technologies based on the resulting findings the potential and limitations of the proposed framework are discussed

the relationship between r d collaboration subsidies and r d performance empirical evidence from finland and germany this study focuses on the impact of innovation policies and r d collaboration in germany and finland we consider collaboration and subsidies as heterogeneous treatments and perform an econometric matching to analyze r d and patent activity at the firm level in general we find that collaboration has positive effects in germany subsidies for individual research do neither exhibit a significant impact on r d nor on patenting but the innovative performance could be improved by additional incentives for collaboration for finnish companies public funding is an important source of finance for r d without subsidies recipients would show less r d and patenting activity whilst those firms not receiving subsidies would perform significantly better if they were publicly funded copyright 2007 john wiley sons ltd

does energy policy hurt international competitiveness of firms a comparative study for germany switzerland and austria this paper investigates the impact of energy policies on the export performance of firms there has been a long policy debate on potentially negative impacts of cost increasing energy policies on international competitiveness we use firm level data from three countries with similar industry structure but different energy policies germany switzerland and austria we rely on firm manager assessments on the relevance of energy policy in terms of taxes regulations standards subsidies and demand stimulation for their firm operation and link data on the adoption and development of new energy technologies regression analyses and matching approaches both show very few impacts of energy policy on export performance suggesting that either policy impacts on firms cost are negligible in the period of study 2012 to 2014 or likely negative impacts are balanced by the adoption of new technology

the impact of carbon emissions trading on the directed technical change in china abstract this paper focuses on whether carbon emissions trading cet has different impacts on the heterogeneous low carbon innovation and how cet affects the direction of technical change taking six cet pilot regions in china as research objectives we set two types of technology as the clean and the gray with cpc y02 patent codes and use the synthetic control method scm in quasi natural experiment moreover this paper analyzes how cet moderates the effects of other three factors that is control and command environment regulation foreign capital inflow and industry structure with different innovations the results show that the effects of cet on the direction of technical change are different across regions cet successfully induces technical change to the clean direction and restrains the gray direction in beijing and shanghai while promoting both innovations in tianjin and hubei only intensifying the gray in guangdong and chongqing these results indicate cet has a significant impact on both innovations but its impact on the direction of technical change seems to be neutral depending more on the balance between the new regulation and existing dependence on technological path in each region further research finds that cet amplifies the positive effect of industry structure upgrading on both kinds of innovations but the response of the clean is more sensitive than that of the gray moreover foreign capital inflow can promote the clean in the current period and inhibit the gray with lags and the significant interaction between cet and foreign capital inflow can not be found however the policy mixed cet with control and command regulation leads to more gray innovation the further analyses imply that cet can be a useful instrument leading to the right direction of technical change under certain backgrounds where industry structure is upgrading more open for foreign investment with less control and command regulations

characterizing the policy mix and its impact on eco innovation a patent analysis of energy efficient technologies abstract this paper provides an empirical investigation of the role played by selected characteristics of the policy mix in inducing innovation in energy efficiency technologies an original dataset covering 23 oecd countries over the period 1990 2010 combines the full set of policies in the energy efficiency domain for the residential sector with data on patents applied over the same period in this specific technological sector the econometric results suggest that when the policy mix is characterised by a more balanced use in demand pull and technology push instruments its positive effects on eco innovation tend to be greater moreover a more comprehensive policy mix is shown to be able to enhance innovation activities for the generation of new energy efficient technologies however the simple addition of an indiscriminate number of simultaneous policy instruments may reduce policy mix effectiveness finally the empirical findings confirm previous evidence on the importance of policy spillover effects and suggest that policy similarity between countries may represent an important aspect to be accounted for in policy mix design

the relevance of the value relevance literature for financial accounting standard setting another view this paper explains that value relevance research assesses how well accounting amounts reflect information used by equity investors and provides insights into questions of interest to standard setters a primary focus of financial statements is equity investment other uses of financial statement information such as contracting do not diminish the importance of value relevance research value relevance questions can be addressed using extant valuation models value relevance studies address econometric issues that otherwise could limit inferences and can accommodate and be used to study the implications of accounting conservatism r 2001 elsevier science b v all rights reserved jel classification m41 m44 g12

the diffusion of clean technologies a review with suggestions for future diffusion analysis abstract this article gives an overview of the literature on clean technology diffusion followed by suggestions for future analysis findings from diffusion analysis are presented in the form of 10 stylised facts helping the reader to see the forest for the trees the overall conclusion is that the diffusion of clean technology same as the diffusion of normal innovations is governed by endogenous mechanism epidemic learning and learning economies and by exogenous mechanisms policy is important for clean technology diffusion but other factors are important too the characteristics of the clean technology absorptive capacities of potential adopters and the age structure of capital it is often overlooked that companies have a choice they can choose between an end of pipe solution a process change adaptation and a change of process substitution this means that the diffusion and evolution of one clean technology will be at the expense of the diffusion of another clean technology something overlooked in studies on clean technology diffusion further research is needed on the influence of public policy on clean technology choice expectations about learning economies and prices adjustment costs network externalities and complementary innovations on clean technology adoption choices

the innovation effects of environmental policy instruments a typical case of the blind men and the elephant abstract in this paper we examine the innovation effects of environmental policy instruments in four literatures theoretical models on incentives for eco innovation econometric studies based on observed data survey analysis based on stated information and technology case studies the aim of this paper is to critically examine the methods and the results we argue that the case studies literature even when its results are specific and difficult to generalise is a necessary source of empirical evidence about policy impacts and the factors responsible for these impacts pointing to issues that are neglected in the theoretical and econometric literature such as the specifics of the innovation context and policy interaction effects the paper states five synthesised findings and makes a plea for multi method analysis one other important synthesised finding is that the influence of market based instruments on innovation such as emission trading and taxes is far weaker than assumed

price cap regulation and technical change abstract existing analyses of the implications of price cap regulation for the development of cost reducing technologies assume that all r d is done by the regulated industry this is unrealistic we present a simple model of non cooperative r d by a regulated firm and a single external developer under a price cap regime of the sort characterised by cabral and riordan in equilibrium the external developer exerts less r d than is socially optimal the regulated firm may exert more or less a tightening of the regulatory regime impacts the r d incentives of both players though in different ways the optimal regulatory adjustment parameter may be bigger or smaller than that suggested by existing studies despite the scope for duplication of results research by an outsider necessarily enhances welfare

comprehensive effectiveness assessment of renewable energy generation policy a partial equilibrium analysis in china abstract in order to stimulate renewable energy and control carbon dioxide emissions the chinese government has already introduced lots of renewable energy generation policies under this background it is of great significant to figure out the economic environmental and social effectiveness of these polices firstly this paper systematically studied the framework and content of renewable energy generation policies secondly this paper built a basic partial equilibrium model to calculate the equilibrium state of electricity market and carbon emissions on this base the effectiveness of seven renewable energy generation policies was analyzed by introducing policies into the basic model and comparing relevant indicators in different policy scenarios with that in basic scenario further an empirical analysis was made to estimate the actual benefits of these policies in china this paper proposed an analysis method for evaluating the mechanism effectiveness and efficiency of renewable energy generation policies all the results and discussions in this paper can provide specific suggestions for chinese government to shape a blueprint for implementing different kinds of policies

the impact of r d on innovation for wind energy in denmark germany and the united kingdom this paper examines the impact of public research and development r d support on cost reducing innovation for wind turbine farms in denmark germany and the united kingdom uk first we survey the literature in this field the literature indicates that in denmark r d policy has been more successful than in germany or the uk in promoting innovation of wind turbines furthermore such studies point out that subsidy induced capacity expansions were more effective in the uk and denmark in promoting cost reducing innovation than in germany the second part of the paper describes the quantitative analysis of the impact of r d and capacity expansion on innovation this is calculated using the two factor learning curve 2flc model in which investment cost reductions are explained by cumulative capacity and the r d based knowledge stock time series data were collected for the three countries and organized as a panel data set the parameters of the 2flc model were estimated focusing on the homogeneity and heterogeneity of the parameters across countries we arrived at robust estimations of a learning by doing rate of 5 4 and a learning by searching rate of 12 6 the analysis underlines the homogeneity of the learning parameters enhancing the validity of the 2flc formulation

induced innovation and energy prices this paper uses u s patent data from 1970 to 1994 to study the impact of energy prices on energy efficient innovations theories of technological change have focused both on demand side factors which spur innovative activity by increasing the value of new innovations and supply side factors such as scientific advancements that make new innovations possible data on demand side factors are easily obtained but data on supply side factors that influence innovation are not readily available this paper uses patent citations as a measure of the usefulness of the existing base of scientific knowledge citations to previous patents are used to construct productivity estimates which measure the usefulness of the existing stock of knowledge to inventors in a given energy field for any given year these estimates are then combined with data on demand side factors to estimate a model of induced innovation in energy technologies the results indicate that both energy prices and the supply of knowledge have strongly significant positive effects on innovation the paper concludes with a discussion of the implication of this work for environmental policy

imitation costs and patents an empirical study it has long been recognised that the costs of imitating new products have an important effect on the incentives for innovation in a market economy as arrow i962 and others have pointed out if firms can imitate an innovation at a cost that is substantially below the cost to the innovator of developing the innovation there may be little or no incentive for the innovator to carry out the innovation in their discussions of the innovation process economists frequently have called attention to the major role played by the costs of imitation but there has been little or no attempt to measure these costs to test various hypotheses concerning the factors influencing them or to estimate their effects in this paper we report some findings of what seems to be the first study of this topic in addition we present data regarding the effects of patents on imitation costs and on the rate of innovation

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

elements of a schumpeterian catalytic research and innovation policy in this article we take a fresh look at research and innovation r i hereinafter policy and define a new notion schumpeterian catalytic r i policy such policy style amends and enriches the new mission oriented framework for innovation policy by assigning more weight to the microeconomic dimension of private actors actions and by being more concerned with the temporary nature of interventions we relate our argument to recent empirical trends in productivity dynamics and innovative activities these suggest that an innovation slowdown is taking place and consequently that a renewed interest in the re direction rather than on the intensity of innovative activities is key to the design of r i policy capable to tackle current challenges we use the evidence to build a schematic theoretical framework to inform policy design and we outlined the defining features of our proposed policy style

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

do policy mix characteristics matter for low carbon innovation a survey based exploration of renewable power generation technologies in germany abstract policy mixes may play a crucial role in redirecting and accelerating innovation towards low carbon solutions thus addressing a key societal challenge towards this end some argue that the characteristics of such policy mixes matter greatly yet with little empirical evidence backing up such claims in this paper we explore this link between policy mix characteristics and low carbon innovation using the research case of the transition of the german electricity system towards renewable energy our empirical insights are based on an innovation survey administered to german manufacturers of renewable power generation technologies which builds on the community innovation survey for our purposes we adjusted the survey to better capture companies perceptions of policy mixes employing a bivariate tobit model we find evidence that companies perceptions regarding the consistency and credibility of the policy mix are positively associated with their innovation expenditures for renewable energies and this positive link intensifies when considering the mutual interdependence of these policy mix characteristics in contrast neither the comprehensiveness of the instrument mix nor the coherence of policy processes were found to be related to innovation expenditures overall these findings suggest that future research on low carbon and eco innovation should pay greater attention to the characteristics of policy mixes rather than focusing on policy instruments only finally our findings indicate a need to consider how policy may be measured in innovation surveys to generate better informed policy advice regarding the greening of innovation

japanese research consortia a microeconometric analysis of industrial policy despite the existence of much theoretical research analyzing the potential benefits and costs of r d consortia there has been little corresponding empirical work on their efficacy in this paper we undertake a large sample econometric study of japanese government sponsored research consortia we find evidence that frequent participation in these consortia has a positive impact on research expenditure and research productivity these results hold after controlling for the potential endogeneity of intensity of participation in consortia to participating firms research productivity furthermore we find evidence that part of this impact arises from the increased knowledge spillovers that take place within these consortia

are firms that received r d subsidies more innovative this paper looks at the effectiveness of r d grants for canadian plants that already benefit from r d tax credits using a non parametric matching estimator we find that firms that benefited from both policy measures introduced more new products than their counterparts that only benefited from r d tax incentives they also made more world first product innovations and were more successful in commercializing their innovations

corporate governance social responsibility information disclosure and enterprise value in china abstract social responsibility information disclosure relates to the long term development of enterprises all social layers pay increasing attention to social responsibility of enterprises especially those in heavy pollution industries that are listed on stock exchanges this study takes chinese companies in heavy pollution industries that were listed during 2008 2014 as objects of study to test the relationships among corporate governance social responsibility information disclosure and enterprise value the study finds that there is a declining level of social responsibility information disclosure of listed enterprises in heavy pollution industries in addition different corporate governance factors affect the social responsibility information disclosure of listed companies in heavy pollution industries to a certain extent furthermore we find that social responsibility information disclosure is not beneficial for the short term profit of an enterprise but can increase its long term value generally a high level of corporate governance is favorable for legitimacy management as well as disclosure of social responsibility information

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

alternative measures of profit margin an empirical study of the potential information content of current cost accounting the primary purpose of this study is to investigate the link between price changes in product markets and price changes in financial markets the nature of the association is central to evaluating the information content of current cost accounting measurements such as those promulgated in the sec s accounting series release no 190 asr 190 and the fasb s statement of financial accounting standards no 33 sfas 33 although both asr 190 and sfas 33 state that financial statements based only on historical costs do not provide investors with sufficient information to assess the underlying economics of firms in periods of rapidly changing prices empirical evidence suggests there was no apparent reaction to the initial replacement cost releases mandated by asr 190 e g see beaver christie and griffin 1980 1 this study offers one explanation for the lack of an observed market

reconceptualising the policy mix for innovation abstract recent years have seen the emergence take up and use of the term policy mix by innovation policy makers and by policy analysts and scholars alike imported from economic policy debates the term implies a focus on the interactions and interdependencies between different policies as they affect the extent to which intended policy outcomes are achieved however the meaning of the term remains ambiguous nonetheless we argue that the emergence of the policy mix concept into common use in the field of innovation policy studies provides us with a window of opportunity to reconsider some basic and often hidden assumptions in order to better deal with a messy and complex multi level multi actor reality we draw upon a range of literatures to re conceptualise the basic building blocks of innovation policy studies in order to arrive at a useful definition of policy mix tensions and interactions of different kinds across a series of dimensions we suggest that this reconceptualisation has important implications for the future scope and focus of prescriptive and analytical innovation policy studies

glass houses market reactions to firms joining the un global compact we examine market reactions to publicly held multinational firms announcing their affiliation with the united nations global compact ungc the ungc is a voluntary initiative to support four areas of united nations viz human rights labor environmental and anti corruption because firms must file annual communication on progress cop reports toward these initiatives we argue this creates a differentiating transparency of interest to stakeholders using a sample of 175 global firms we find support to the theory for joining the ungc returns differ markedly however between multinational firms headquartered in the united states negative and europe positive we also find that failing to complete the annual cop generates a negative market reaction

in search of complementarity in innovation strategy internal r d and external knowledge acquisition empirical research on complementarity between organizational design decisions has traditionally focused on the question of existence of complementarity in this paper we take a broader approach to the issue combining a productivity and an adoption approach while including a search for contextual variables in the firms strategy that affects complementarity analysis of contextual variables is not only interesting per se but also improves the productivity test for the existence of complementarity we use our empirical methodology to analyze complementarity between innovation activities internal research and development r d and external knowledge acquisition our results suggest that internal r d and external knowledge acquisition are complementary innovation activities but that the degree of complementarity is sensitive to other elements of the firms strategic environment we identify reliance on basic r dthe importance of universities and research centers as an information source for the innovation processas an important contextual variable affecting complementarity between internal and external innovation activities

assessing the effect of public subsidies on firm r d investment a survey this survey examines the empirical literature on the relationship between public r d subsidies and private r d investment over the past five decades the survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues we aim to provide further explanations of the possible causes of that heterogeneity in particular we emphasise a set of issues that in our view are critical to understanding the potential effect of public r d subsidies on private r d spending special attention is paid to the dynamic aspects and composition of firm r d the constraints faced by the firm such as financial constraints and the amount and source of public subsidies none of these issues have been investigated in depth we formulate a set of research assumptions to guide future empirical research in this field

do support systems for res e reduce eu ets driven electricity prices abstract support systems for electricity from renewable energy sources res e can reduce electricity prices which have also been influenced by a co2 emission trading scheme ets additional res e substitutes electricity from fossil fuels and thus co2 emissions are reduced the demand for emission reductions is lowered as a result the co2 price is also reduced consequently the wholesale price for electricity decreases however most res e support systems are financed via the electricity market which increases the retail electricity price an assessment for germany shows that retail electricity prices in the first trading period of the eu ets 2005 2007 are lowered by 2 6 euro mwh due to additional res e considering the complete eu the effect is substantially higher this paper describes the effect and the influence of different policy designs it develops an approach for assessing the effect and applies it for the case of germany and roughly estimates the effect for the eu

innovation in pollution control comparisons of the various institutional arrangements for controlling pollutant emissions from individual sources effluent fees effluent control subsidies marketable permits and direct command and control regulation have usually focused on their static efficiency properties and institutional feasibility e g dales 1968 zerbe 1970 baumol and oates 1975 kneese and schultze 1975 marin 1978 mills and white 1978 spence and weitzman 1978 russell 1979 a relatively neglected area has been the study of how each arrangement influences innovation in pollution control a few studies e g kneese and schultze 1975 marin 1978 mills and white 1978 russell 1979 have casually claimed that the control methods that rely on economic incentives provide superior incentives for innovation but there have been few systematic studies of the question this paper provides a simple model of pollution control innovation by a profitmaximizing polluter who is subject to the various control methods the consequences of the methods will be explored in three major contexts first we assume that the polluter and the innovation is a small enough part of the overall pollution problem so that none of the important marginal conditions are changed by the innovation second we assume that the polluter and the innovation are important enough so that marginal conditions are changed by the innovations but that the governmental authority determining pollution control incentives or levels fails to make the appropriate adjustments third we again assume that the innovation causes marginal conditions to change but in this case the governmental authority makes the appropriate adjustments we use the term ratcheting to describe this last phenomenon in all cases we assume that the innovating polluter correctly predicts the reactions of the governmental authority and bases his innovation decisions on that prediction a profit maximizing entrepreneur would normally be expected to adopt any innovation that promised gains present discounted value to him in excess of initial

exploring the effects of social responsibility on coordination and profit division in a supply chain abstract this paper explores channel coordination and profit division in a socially responsible manufacturer retailer chain through sub game perfect equilibrium and extended alternative offer bargaining the channel members jointly intend to swell stakeholder s welfare by exhibiting corporate social responsibility csr in a proportion it is found that i the channel s non profit maximizing motive through csr practice generates higher profit margin than would the profit maximizing objective ii the manufacturer s wholesale price is below its marginal cost or negative above some thresholds of csr and csr sharing fraction iii the csr and csr sharing fractions are key determining factors for the pure profits of the channel members because variations in choosing these two factors can lead to increment or decrement even negative pure profits on the other hand for the csr manufacturer the wholesale price is less than the marginal cost for csr practice above a threshold and is negative for heavy csr practice though always larger than the marginal cost for the csr retailer so the manufacturer s pure profit may be negative moreover a channel member always prefers the other s csr practice thus in cooperative environment equitable share of csr may be a compromise solution

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

network structure and the diffusion of knowledge this paper models knowledge diffusion as a barter process in which agents exchange different types of knowledge this is intended to capture the observed practice of informal knowledge trading agents are located on a network and are directly connected with a small number of other agents agents repeatedly meet those with whom direct connections exist and trade if mutually profitable trades exist in this way knowledge diffuses throughout the economy we examine the relationship between network architecture and diffusion performance we consider the space of structures that fall between at one extreme a network in which every agent is connected to n nearest neighbours and at the other extreme a network with each agent being connected to on average n randomly chosen agents we find that the performance of the system exhibits clear small world properties in that the steady state level of average knowledge is maximal when the structure is a small world that is when most connections are local but roughly 10 percent of them are long distance the variance of knowledge levels among agents is maximal in the small world region whereas the coefficient of variation is minimal we explain these results as reflecting the dynamics of knowledge transmission as affected by the architecture of connections among agents

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

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

the incremental information content of replacement cost earnings abstract the study explores the incremental explanatory power of replacement cost earnings variables derived from asr 190 data with respect to explaining cross sectional differences in security returns as such the study is a natural extension of previous research including analyses of the effect of security returns of asr 190 data at the time of disclosure investigations of cross sectional relationships between security returns and historical cost earnings and studies of multiple signals the basic finding is that pre holding gain net income provides no incremental explanatory powerm given knowledge of historical cost earnings however the converse does not hold taken together the findings are consistent with the contention that pre holding gain net income is a garbled version of historical cost earnings the basic finding is robust under several extensions of the initial research design the research design incorporates a two stage approach which permits a determination of the incremental explanatory power of collinear variables the findings are in contrast to those of a previous study by easman et al 1979 the nature of the difference in research design inducing the difference is identified potential reasons for the difference in findings are provided

realizing innovative public waterworks aligning administrative capacities in collaborative innovation processes abstract the importance of government support for innovation is widely acknowledged but the way governments support innovation is changing we discern three trends local innovation policies are gaining importance governments increasingly choose a bottom up tailor made approach to support specific innovations and there is more collaboration between public and private actors we analyse these trends and investigate how modern governments employ their administrative capacities to support innovation we conduct a comparative case study of four attempts to realize integrated energy and waterworks combining water safety and sustainable energy generation despite broad support attempts to realize such innovative multifunctional works in the netherlands have had varying degrees of success we examine the governmental support for these attempts and assess how governments actions affect the innovation process we conclude that all governmental administrative capacities have to be employed and that public alignment is crucial for a synchronized endeavour we elucidate the growing importance and special role of local authorities in innovation and demonstrate how modern governments spur innovation with tailor made support in close collaboration with the private sector we further conclude that encouraging interaction is an insufficient public contribution to innovation and that expectations must be carefully managed to avoid role confusion in public private innovation

demand side vs supply side technology policies hidden treatment and new empirical evidence on the policy mix this paper provides new empirical evidence about the impact of various technological policies upon firms innovative behaviour we take into consideration the role of policies for innovative activities and we focus on their interaction while supply side policies such as r d subsidies and tax credits have been both extensively discussed in the literature and empirically investigated the analysis of innovative public procurement is a growing trend in the literature which still lacks robust empirical evidence in this paper we replicate the existing results on supply side policies surmise fresh empirical evidence on the outcome of innovative public procurement and address the issue of possible interaction among the various tools when controlling for the interaction with other policies supply side subsidies cease to be as effective as reported in previous studies and innovative public procurement seems to be more effective than other tools the preliminary evidence suggests that technology policies exert the highest impact when different policies interact

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

corporate social responsibility in europe and the u s insights from businesses self presentations the paper compares the extent and content of businesses communications about corporate social responsibility csr in france the netherlands the u k and the u s in particular the study investigates the nature of csr principles processes and stakeholder issues discussed in web pages the results show that businesses in the four countries do not display the same eagerness to appear as socially responsible and employ diverse means to convey social responsibility images

compulsive policy making the evolution of the german feed in tariff system for solar photovoltaic power abstract in recent years policy approaches that build upon the notion of innovation systems have enjoyed increasing attention in science technology and innovation policy but while the usefulness of systemic thinking in policy making has been demonstrated in a large number of empirical settings we still lack a detailed understanding of the dynamics at play when policy makers address systemic problems in this paper we show how complex interdependencies and the uncertain nature of technological change shape the process of targeted policy interventions in socio technical systems toward this end we analyzed the evolution of the german feed in tariff fit system for solar photovoltaic power a highly effective and widely copied policy instrument targeted at fostering the diffusion and development of renewable energy technologies we find that the policy has been subject to a considerable amount of changes many of which are the result of policy makers addressing specific system issues and bottlenecks interestingly however often these issues themselves were driven by unforeseen technological developments induced by previous policy interventions we argue that the pattern of policy serving as both a solution to and a driver of technological bottlenecks shows strong similarities with what rosenberg 1969 called compulsive sequences in the development of technical systems by shedding more light on how the characteristics of socio technical systems affect policy interventions our framework represents a first step toward more closely integrating the literature on innovation systems with the work on policy learning

governing corporate social responsibility an assessment of the contribution of the un global compact to csr strategies in the telecommunications industry csr has become an important element in the business strategy of a growing number of companies worldwide a large number of initiatives have been developed that aim to support companies in developing implementing and communicating about csr the global compact gc initiated by the united nations stands out since its launch in 2000 it has grown to about 2900 companies and 3800 members in total the gc combines several mechanisms to support csr strategies normative principles networks for learning and co operation and communication and transparency about csr activities however up to now only a few empirical evaluations of the contribution of the gc to csr strategies have been conducted that however have not differentiated between different types of companies regarding type of industry or regarding the maturity of csr this paper aims to partly fill this knowledge gap by a case study examination of three frontrunner companies in the telecommunications industry the results show that the gc is only one of the many initiatives that these companies employ in shaping implementing and reporting about their csr strategies and that its role is at most modest there are two important reasons one is that many of the csr issues that these companies deal with are industry specific and are hence addressed in specific networks the second reason is that the gc principles are perceived as minimum requirements that do not provide many incentives to the three case study companies to perform better a differentiation of norms for gc members is expected to enhance the contribution of the gc to csr strategy employment not only for frontrunner companies but as well for other categories of companies

valuation and accounting for inflation and foreign exchange inflation and foreign exchange raise new issues with respect to accounting representations of equity value for example inflation creates an earnings illusion as an artifact of the mismatching of expenses based on allocations of historical costs with current revenues in determining earnings this mismatching distorts mappings of aggregate earnings and book values into equity value such that value relevant information is lost in this article we consider the consequences of inflation and foreign exchange accounting policies including those contained in accounting standards on the value relevance of bottom line accounting numbers policies are identified that achieve efficient accounting in the sense that aggregate comprehensive earnings and book values are sufficient for an accounting representation of equity value the linear relations that emerge provide predictions on capitalization coefficients that help explain results of empirical inquiries as well our analysis provides a theoretical foundation for policies contained in accounting standards that contributes to the resolution of controversies such as that concerning foreign exchange accounting

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

inventor networks in renewable energies the influence of the policy mix in germany technological change and gains in efficiency of renewable power generation technologies are to a large extent driven by governmental support various policy instruments that can broadly be categorized as technology push demand pull or systemic constitute part of the policy mix for renewable energies our goal is to gain insights into the influence of this policy mix on the intensity and organization of inventive activities for wind power and photovoltaics in germany since the 1980s we examine the effect of different instruments on the size and structure of co inventor networks based on patent data our results indicate notable differences between the technologies the network size for wind power is driven by technology push and systemic instruments while in photovoltaics demand pull is decisive for network growth by and large the instruments complement each other and form a consistent mix of policy instruments the structure of the networks is driven by demand pull for both technologies systemic instruments increase interaction especially in the wind power network and are complementary to demand pull in fostering collaboration

demand pull and technology push public support for eco innovation the case of the biofuels sector the purpose of this paper is to explore the differentiated impact of demand pull and technology push policies in shaping technological patterns in the biofuels sector the empirical analysis is based on a novel and original database biopat containing patents in the field of biofuels selected using appropriate keywords and classified according to the technological content of the invention our results generally show that technological capabilities and environmental regulation spur innovative activities in the biofuels sector both demand pull and technology push factors are found to be important drivers of innovation in the biofuels sector however technology exploitation activities in first generation technologies are found to be mainly driven by quantity and price based demand pull policies on the contrary the pace of technology exploration efforts in advanced generation biofuels is shown to react positively to price based demand pull incentives but also to technology push policy the clear diversity in the impact of different public support instruments provides new insights which fuel discussion on the optimal policy mix debate and offers new elements for the design of future policy strategies

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
