power systems expansion planning with time varying co2 tax abstract this article analyzes the effects of implementing a two stage carbon tax on a ten year power expansion planning model the timing effect of the tax is analyzed by studying the costs capacity investments economic dispatch and co 2 emissions in fixed flat and two stage tax schemes results show that under the absence of political economy constraints the most cost effective solution is to have a low co 2 tax in the first stage and an optimal higher tax in the final stage however early actions can be justified depending on how relevant the policy maker considers the beneficial economic and not economic outcomes of a higher first stage tax consequently focusing on a final period goal may not be the best way of facing the global warming problem if emissions saved early have an important value when preventing the consequences of climate change

knowledge spillovers and patent citations evidence from a survey of inventors it is well understood that the non rival nature of knowledge as a productive asset creates the possibility of knowledge spillovers whereby investments in knowledge creation by one party produce external benefits by facilitating innovation by other parties at least since zvi griliches s 1979 seminal paper on measuring the contributions of r d to economic growth economists have been attempting to quantify the extent and impact of knowledge spillovers one line of research of this type has utilized patent citations to identify a paper trail that may be associated with knowledge flows between firms very little of this research has attempted to determine the modes or mechanisms of communication that actually permit knowledge to flow further most of the work has simply assumed that citations or other proxies are sufficiently correlated with knowledge flows to allow statistical analysis of the proxies to be informative regarding the underlying phenomenon of interest this paper reports on a preliminary attempt to improve this situation the idea for this survey came from r d managers whom we were interviewing to test whether the picture of knowledge flows produced by patent citations was consistent with the managers impressions one of these managers commented that he could not let us talk to the scientists who worked for him but that he could not stop uls from contacting them via the postal address that appears on their issued patents the survey results suggest that communication between inventors is reasonably irnportant and that patent citations do provide an indication of communication albeit one that also carries a fair amount of noise

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

measuring entrepreneurship over time abstract this article is a review of three measurement issues that impact the study of entrepreneurship over time 1 level of analysis difference between firms and individuals 2 differences between rate and stock measures and 3 the effects of choosing particular time frames on subsequent analytical results based on theory that views entrepreneurship as depending on ownership rights hawley 1907 this article develops a longitudinal measure of entrepreneurship in the united states the number of organizations per capita the problems and advantages of using a measure based on organizations per capita as an indicator of entrepreneurship is examined understanding how and what is being measured in studies of changes in entrepreneurship over time is an important issue for academic researchers and public policy makers measurement of changes in entrepreneurship over time can shed light on important research questions and public policy issues about entrepreneurship for example is entrepreneurship increasing in the united states if entrepreneurship is increasing is this trend comparable to any previous time periods or is the current increase in entrepreneurship a new or unique social phenomenon what influences changes in entrepreneurship over time the choice of certain measures of entrepreneurship is likely to influence the answers to these questions for example the measures used in an entrepreneurship study are an implicit specification of one s views of entrepreneurship e g entrepreneurship as self employment or firm creation and few measures of entrepreneurship reflect critical changes in important environmental influences e g technological change because of short measurement time frames therefore determining the contribution of entrepreneurship to the well being of an economy is dependent on understanding what measures of entrepreneurship are utilized for making these evaluations and the time frame used for these measures we review three measurement issues that impact the study of entrepreneurship over time 1 level of analysis differences between firms and individuals 2 differences between rate and stock measures and 3 the effects of choosing particular time frames on subsequent analytical results based on theory that views entrepreneurship as depending on ownership rights hawley 1907 this article develops a longitudinal measure of entrepreneurship in the united states the number of organizations per capita studies of entrepreneurship focus on either individual level activity e g self employment or on firm level activity e g new incorporations self employment research focuses on individuals who employ themselves that is individuals who report wages but not wages paid to them by other individuals or organizations in most studies of the self employed firm founders would therefore be classified as wage earners and not as entrepreneurs new firm research focuses on the rate of new firm entrants typically measured as new incorporations so such businesses as proprietorships or partnerships will not be counted a rate is a change from one state to another e g the number of people who become self employed for a specific year or the number of new firms created for a specific year whereas a stock specifies a particular level e g much like a stock of inventory such as the number of self employed or a particular number of firms for a specific time period it is important to recognize that entry into business does not necessarily guarantee remaining in business for example although the number of people who become self employed may increase for a specific year the number of people who remain self employed may actually decrease if more of the self employed fail to remain in business than those that enter the stock of the self employed can decrease if the outflow of self employed is greater than the inflow for those persons interested in whether entrepreneurial activity results in wealth creation either individually or societally the realization that entry into business may not lead to a sustainable business and therefore no creation of wealth should be a signal that measuring rates of business formation and rates of self employment may not be appropriate for this type of research the factors that drive changes in the rate of entrepreneurship are not likely to be manifest over short timeperiods changes in values attitudes technology government regulations and world economic and social changes have a significant influence on changes in entrepreneurship over time studies that have measured entrepreneurship over recent time periods are therefore likely to miss the influence of these variables we introduce a measure of entrepreneurship organizations per capita based on a theory of entrepreneurship as ownership this measure shows the stock of organizations in the u s economy over time from 1857 to 1992 the problems and advantages of using a measure based on organizations per capita as an indicator of entrepreneurship is examined we conclude with some suggestions for improving entrepreneurship research by recognizing the limitations of particular longitudinal entrepreneurship measures and by challenging the field to seek convergent validity among measures

is the efficiency wage efficient the social norm and organizational corruption the effectiveness of efficiency wage incentives is often jeopardized by perverse organizational corruption we model organizational corruption as a phenomenon of social interaction and relate the substantial psychological role characterizing the social norm to the corruption problem we find that if the status quo bribery rate within the firm is high social norms can no longer serve as a sufficient sanction against a corrupt supervisor pandemic organizational corruption tends to generate a critical mass effect the snowball effect which intensifies the corruption effect this intensified effect due to the snowballing character of social norms may more than offset the usual incentive effect of wages resulting in more widespread shirking in the firm jel classification d82 j41

carbon tax or emissions trading an analysis of economic and political feasibility of policy mechanisms for greenhouse gas emissions reduction in the mexican power sector this study provides a comparative assessment of carbon pricing instruments for the mexican electricity sector contrasting a carbon tax with an emissions trading scheme ets the assessment is per

identifying barriers toward a post growth economy a political economy view abstract in this paper we take a political economy perspective on barriers that inhibit a transition beyond the growth paradigm that is we frame transition barriers as looming conflicts of interest specifically we investigate potential transition barriers within three case studies first unemployment represents the most commonly cited reason why economic growth is considered indispensable second alternative indicators to gross domestic product gdp have not succeeded in replacing gdp as a standard metric of economic welfare third pension schemes rely on economic growth to offset demographic change in each of these three examples we identify actor interest constellations that foster the status quo of a growth economy we conclude that compensating some of those actors who would presumably be worse off in a post growth economy may be necessary though not sufficient for a transition

valuing carbon assets for high tech with application to the wind energy industry abstract in contrast to the traditional methods for high tech evaluation we introduce a new more active idea for considering the carbon asset effect in addition to the economic and technological considerations for strategic significance the method proposed in this paper considers a reduced amount of carbon emissions less than that of the current industry baseline to be an asset that is beneficial to a firm that adopts a new technology the measured carbon asset values vary across different technologies in different industries and over time the new method is applied to the valuing of wind energy technology and uses the weibull distribution to estimate the wind energy capacity and a concrete sensitivity analysis these applications support the validity of the new method and show that the impact of the fluctuations of carbon sinks on the values of carbon assets is significantly greater than that of volatility in the production output the paper also presents some policy recommendations based on the results

collusion under asymmetric information when applied to groups the revelation principle postulates a bayesian nash behavior between agents their binding agreements are unenforceable or the principal can prevent them at no cost we analyze instead a mechanism design problem in which the agents can communicate between themselves and collude under asymmetric information we characterize the set of implementable collusion proof contracts both when the principal offers anonymous and nonanonymous contracts after having isolated the nexi and the stakes of collusion we proceed to a normative analysis perform some comparative statics discuss our concept of collusion proofness and provide some insights about transaction costs in side contracting

fuel taxes an important instrument for climate policy abstract this article shows that fuel taxes serve a very important role for the environment and that we risk a backlash of increased emissions if they are abolished fuel taxes have restrained growth in fuel demand and associated carbon emissions although fuel demand is large and growing our analysis shows that it would have been much higher in the absence of domestic fuel taxes people often assert that fuel demand is inelastic but there is strong research evidence showing the opposite the price elasticity is in fact quite high but only in the long run in the short run it may be quite inelastic which has important implications for policy makers had europe not followed a policy of high fuel taxation but had low us taxes then fuel demand would have been twice as large hypothetical transport demand in the whole oecd area is calculated for various tax scenarios and the results show that fuel taxes are the single most powerful climate policy instrument implemented to date yet this fact is not usually given due attention in the debate

cooperation in ongoing organizations this paper argues that overlapping games can provide a natural theory of long lived organizations it shows that participation in organizations of infinite duration changes the incentives of agents with finite lives and will induce more cooperation than a static model would predict after developing the general theory we apply it to the description of career paths in organizations and show that it can be optimal to give the youngest workers the most arduous tasks

supplementing an emissions tax by a feed in tariff for renewable electricity to address learning spillovers abstract in the presence of learning spillovers related to renewable energy technologies an optimal strategy to mitigate climate change should complement an emissions tax by a subsidy for renewables this article addresses the question how such subsidy should be designed it is shown that the widely used approach of a revenue neutral fixed feed in tariff can yield an optimal outcome under restrictive conditions only it has to be adapted continuously as the electricity price changes moreover funding the tariff by a surcharge on the electricity price has important implications for the design of the emission tax the optimal tax rate has to be below the pigovian level differentiated across fossil fuels and adapted over time as the patterns of technological development change these requirements may pose a formidable challenge for practical decision making however it is important to point out that the eventual choices made with respect to the design and funding of a feed in tariff have to be based on a careful and more comprehensive policy assessment including inter alia economic effects beyond the electricity sector and existing institutional constraints

energy consumption and co2 emissions convergence in european union member countries a tonneau des danaides abstract as the consumption of energy is responsible for approximately 80 of ghg in eu iea 2008 the impact of energy activity on the environment has received increasing attention over the last decades from scholars researchers politicians and society as a whole within eu member countries it is commonly accepted that the design of energy and mitigation policies either at national or at european level require a detailed and integrated investigation of convergence divergence pattern among the participating countries in this paper we examine the distribution dynamics of energy consumption and co2 emissions their intensities as well as the carbonization index in 23 european countries over a forty one year period in particular from 1970 to 2010 for this purpose we used quah s methodology which is based on the dynamics of cross section distributions the main conclusion is that for all the examined variables the hypothesis of convergence patterns for the eu sample is not valid moreover regarding each examined variable different groups of polarization established important differences occur across eu countries according to the climate type with respect to the examined variables our analysis provides strong evidence supporting the fact that national and european energy and mitigation policies should be implemented according to the non convergence paradigm the body of evidence provided by our analysis is of great importance to energy policy makers and for issues related to climate change

reducing energy demand a review of issues challenges and approaches most commentators expect improved energy efficiency and reduced energy demand to provide the dominant contribution to tackling global climate change but at the global level the correlation between increased wealth and increased energy consumption is very strong and the impact of policies to reduce energy demand is both limited and contested different academic disciplines approach energy demand reduction in different ways emphasising some mechanisms and neglecting others being more or less optimistic about the potential for reducing energy demand and providing insights that are more or less useful for policymakers this article provides an overview of the main issues and challenges associated with energy demand reduction summarises how this challenge is framed by key academic disciplines indicates how these can provide complementary insights for policymakers and argues that a sociotechnical perspective can provide a deeper understanding of the nature of this challenge and the processes through which it can be achieved the article integrates ideas from the natural sciences economics psychology innovation studies and sociology but does not give equal weight to each it argues that reducing energy demand will prove more difficult than is commonly assumed and current approaches will be insufficient to deliver the transformation required

addressing climate change with a comprehensive us cap and trade system there is growing impetus for a domestic us climate policy that can provide meaningful reductions in emissions of carbon dioxide co2 and other greenhouse gases i describe and analyse an up stream economy wide co2 cap and trade system which implements a gradual trajectory of emissions reductions with inclusion over time of non co2 greenhouse gases and includes mechanisms to reduce cost uncertainty initially half of the allowances are allocated through auction and half through free distribution with the share being auctioned gradually increasing to 100 per cent over 25 years the system provides for linkage with emission reduction credit projects in other countries harmonization over time with effective cap and trade systems in other countries and regions and appropriate linkage with actions taken in other countries in order to establish a level playing field among domestically produced and imported products

businesses without glamour an analysis of resources on performance by size and age in small service and retail firms abstract research on factors influencing performance in new and small companies is extensive earlier work found that strategies e g cost quality differentiation etc affected performance contingent on industry conditions the environment and the entrepreneur s background although this work provides a solid basis for understanding differences in entrepreneurial performance some firms are limited in their choices of strategy due to size age or industry often these firms are in industries where entry barriers are low and competitive advantages are easily imitated small service and retail businesses operate in sectors where these conditions are apparent comprising more than 50 of all small firms they require minimal start up investments but face intense competition lacking the glamour of high innovation high growth firms service and retail companies are at the end of the value chain their fortunes rising and falling as a result of the direct influence of the owner founder hence performance variation may be better explained by the capabilities of the firm or individual competencies of the owner founder that is the resource base and resource combinations rather than strategy the strategic importance of an organization s resources and capabilities is the foundation of resource based theory resources are tangible and intangible assets tied to the firm in a relatively permanent fashion their combinations are heterogeneous and form the basis for product market strategies studies of resources strategies and performance are emerging in the entrepreneurial area research shows that various resources in concert with different strategy types can lead to above average performance over the business life cycle and that combinations of resources are related to survival yet the vast majority of work focuses on high growth high tech or manufacturing businesses less is known about the relationships of resources to performance in less glamorous sectors in these small service and retail businesses we speculate that resources in particular human and organizational resources may play a greater role in explaining performance than strategy further as other authors have suggested it is expected that the combinations of these resources will vary across age and size this study examines the influence of human and organizational resources on performance in a sample of 195 service and retail firms operating in central new jersey using a structured questionnaire all companies utilized a focus strategy either focused cost or focused differentiation and employed a minimum of 3 to a maximum of 100 employees all measures had theoretical and or empirical precedent and were tested statistically for reliability we used factor analysis to reduce the independent variables to two human resource variables owner resources and commitment one organizational resource variable comprised of planning systems and staff skills and one strategy variable focused cost and focused differentiation control variables were business age business size environmental benignness and industry growth the dependent variable performance was measured in two ways net cash flow and log of growth in employees over 3 years the study first examined whether strategy or resources had a greater influence on performance results showed that strategy influenced performance less than human and organizational resources both individually and interactively the influence of owner resources background and attitudes on net cash flow was stronger than on growth where the only significant variable was industry market growth to analyze effects of resources on performance by size we divided the sample by size groupings selecting the smallest maximum five employees and largest quartiles minimum 16 employees which were comprised of 55 and 50 companies respectively these analyses showed that owner resources commitment and organizational resources contributed positively to net cash flow in very small firms however interactive effects of these resource combinations were negative for instance owner resources and organizational resources together and organizational resources and commitment together resulted in less positive cash flow than when analyzed separately this implies that different resource combinations can have negative influences in these very small firms we examined age effects in the same manner as size dividing the sample into age group quartiles and conducting an analysis only for very young fewer than 5 years and very old minimum 19 years groups which comprised 54 and 52 companies respectively these analyses showed that although growth was more rapid among the youngest firms there were no distinctive resource based correlates to growth in either age group substantive increases in formalized systems and procedures were not apparent among the oldest of these companies compared with the youngest contrary to previous work showing the evolution of these over business life cycles results of this study are applicable only in the context of service and retail firms and readers should note this sample was nonrandom and geographically concentrated our purpose was not to predict but describe associations between resources and performance this study shows that for firms in competitive industries at the end of the value chain type of strategy is less important than resource combinations for certain types of performance human and organizational resources are associated with more positive cash flow whereas industry and market factors are related to growth these results imply that firms seeking growth are best served by selecting and entering growth markets and industries on the other hand if strong positive cash flows are the primary objective attention to combinations of resources is more important for instance owner founders having a strong business and managerial background and industry experience will need less formalized systems whereas those owner founders with weaker managerial resources might benefit from more formalized procedures and skilled staff

tail hedge discounting and the social cost of carbon the choice of an overall discount rate for climate change investments depends critically on how different components of investment payoffs are discounted at differing rates reflecting their underlying risk characteristics such underlying rates can vary enormously from 1 percent for idiosyncratic diversifiable risk to 7 percent for systematic nondiversifiable risk which risk adjusted rate is chosen can have a huge impact on cost benefit analysis in this expository paper i attempt to set forth in accessible language with a simple linear model what i think are some of the basic issues involved in discounting climate risks the paper introduces a new concept that may be relevant for climate change discounting the degree to which an investment hedges against the bad tail of catastrophic damages by insuring positive expected payoffs even under the worst circumstances the prototype application is calculating the social cost of carbon jel c51 q54 q58

carbon pricing and deep decarbonisation abstract experts frequently point to carbon pricing as the most cost effective tool for reducing greenhouse gas emissions empirical studies show that carbon pricing can successfully incentivise incremental emissions reductions but meeting temperature targets within defined timelines as agreed under the paris agreement requires more than incremental improvements it requires achieving net zero emissions within a few decades to date there is little evidence that carbon pricing has produced deep emission reductions even at high prices while much steeper carbon prices may deliver greater abatement political economy constraints render their feasibility doubtful an approach with multiple instruments including technology mandates and targeted support for innovation is indispensable to avoid path dependencies and lock in of long lived high carbon assets we argue that carbon pricing serves several important purposes in such an instrument mix but also that the global commitment to deep decarbonisation requires acknowledging the vital role of instruments other than carbon pricing

how will the chinese national carbon emissions trading scheme work the assessment of regional potential gains abstract the implementation of a national emissions trading scheme ets in china is likely to have an important effect on potential regional gains this study proposes a unified analytical framework for anticipating such gains in 2020 and estimates the key factors involved using data envelopment analysis based models the results indicate that 1 when the value of the marginal abatement cost is higher than the carbon price no regions will have an incentive to reduce emissions by technological improvements the only source of direct potential gains is from the amounts of carbon quota 2 as carbon price increases from cny 10 to 4000 per ton the indirect potential gains will increase because the strategies for carbon reduction are technological innovation or limit economic activities however jiangsu and shanghai will suffer potential losses even though the price is high because they have no more carbon reduction potential 3 most central provinces will have potential gains when the carbon price is lower in ets while regions rich in fossil energy sources will suffer potential losses however a middle price interval of cny 1000 2000 ton is more rational because it helps motivate market transactions and benefits low carbon technological innovations

political economy constraints on carbon pricing policies what are the implications for economic efficiency environmental efficacy and climate policy design abstract economists traditionally view a pigouvian fee on carbon dioxide and other greenhouse gas emissions either via carbon taxes or emissions caps and permit trading cap and trade as the economically optimal or first best policy to address climate change related externalities yet several political economy factors can severely constrain the implementation of these carbon pricing policies including opposition of industrial sectors with a concentration of assets that would lose considerable value under such policies the collective action nature of climate mitigation efforts principal agent failures and a low willingness to pay for climate mitigation by citizens real world implementations of carbon pricing policies can thus fall short of the economically optimal outcomes envisioned in theory consistent with the general theory of the second best the presence of binding political economy constraints opens a significant opportunity space for the design of creative climate policy instruments with superior political feasibility economic efficiency and environmental efficacy relative to the constrained implementation of carbon pricing policies this paper presents theoretical political economy frameworks relevant to climate policy design and provides corroborating evidence from the united states context it concludes with a series of implications for climate policy making and argues for the creative pursuit of a mix of second best policy instruments

carbon trading in the policy mix the kyoto protocol is stimulating the development of emissions trading schemes at the national and international levels these are being introduced alongside existing policy instruments such as carbon taxes and negotiated agreements leading to complex problems of policy interaction but the topic of policy interaction remains under researched this paper aims to improve understanding of such interactions by examining the conditions under which a cap and trade scheme for carbon dioxide emissions may usefully coexist with carbon energy taxes support mechanisms for renewable electricity and policies to promote energy efficiency the paper argues that each of these instrument combinations may be acceptable provided they contribute to either improving the static or dynamic efficiency of the trading scheme or delivering other valued policy objectives but since the coexisting instruments may raise overall abatement costs while contributing nothing further to emission reductions the objectives and trade offs within the policy mix must be explicit

solar feed in tariffs in a post grid parity world the role of risk investor diversity and business models over the past decade feed in tariffs have spurred significant deployment of solar photovoltaics in germany and other countries with recent cost trends several countries are approaching retail grid parity some policymakers conclude that now is the time to remove feed in tariffs as grid parity creates a self sustaining market where economically rational investors will invest even in the absence of government incentives recent experience in key european solar markets however shows that with the advent of grid parity and the reduction of feed in tariffs investment in new solar capacity has decreased rather than increased making it questionable whether low carbon energy policy targets will be reached we conduct a cross case study analysis of three pv markets germany italy and switzerland to investigate the role of feed in tariffs for the near and post grid parity stages of diffusion accounting for investor diversity and distinguishing between implications for revenue based and savings based business models we find that recent market trends are strongly driven by increased levels of risk especially policy risk and exposure to revenue risk we therefore suggest that relatively frugal but stable policy environments may be conducive to further growth of investment in photovoltaics and minimize cost to society

a theory of bureaucratization based on reciprocity and collusive behavior this paper addresses how an organization becomes a bureaucracy bureaucratization emerges from a self enforced norm of reciprocity between agents in an organization who exchange favors and promote subgoals which differ from the objective of the firm such collusive behavior becomes harder and harder to prevent over time as a result incentive schemes lose their flexibility and bureaucratization becomes a necessary equilibrium phenomenon in the long run the distribution of agents private information their preferences for the future and the force of the social norm of reciprocity are analyzed in terms of their effects on the long run behavior of the organization and on the speed of the bureaucratization process i introduction any theory of bureaucracy concerned with the analysis of the public sector or designed to understand the behavior of private organizations2 must find out why states and firms end up being more and more inefficient over time why organizations become routinized as they grow older and why unflexible rules unavoidably emerge in the long run in other words any theory of bureaucracy should also be accompanied by a theory of bureaucratization which could help us to understand organizations from a dynamic point of view following weber 1978 we hereafter define the bureaucratization of an organization as the process by which it adopts less flexible rules over time the aim of this paper is to explain this process in the case of the theory of the firm the formation of a dynamic theory of organizations has been on the research agenda at least since marshall who was the first to point out that old organizations and firms tend to decline over time first such

the folk theorem with imperfect public information the authors study repeated games in which players observe a public outcome that imperfectly signals the actions played they provide conditions guaranteeing that any feasible individually rational payoff vector of the stage game can arise as a perfect equilibrium of the repeated game with sufficiently little discounting the central condition requires that there exist action profiles with the property that for any two players no two deviations one by either player give rise to the same probability distribution over public outcomes the results apply to principal agent partnership oligopoly and mechanism design models and to one shot games with transferable utilities copyright 1994 by the econometric society

designing climate mitigation policy this us paper provides an exhaustive review of critical issues in the design of climate mitigation policy by pulling together key findings and controversies from diverse literatures on mitigation costs damage valuation policy instrument choice technological innovation and international climate policy the authors begin with the broadest issue of how high assessments suggest the near and medium term price on greenhouse gases would need to be both under cost effective stabilization of global climate and under net benefit maximization or pigouvian emissions pricing the remainder of the paper focuses on the appropriate scope of regulation issues in policy instrument choice complementary technology policy and international policy architectures

emissions pricing spillovers and public investment in environmentally friendly technologies in a second best world of below optimal pollution pricing the public return to r d may be greater than under pigouvian pricing due to excess benefits of increasing abatement or it may be lower since private actors lack the incentives to take full advantage of the new cleaner technologies this paper uses a simple model to demonstrate the interaction between environmental policies r d externalities and the social return to innovation the results indicate that strong public support for innovation in abatement technologies is only justified if at least a moderate emissions policy is in place and spillover effects are significant if emissions policy can adjust to cost changes the public role may be enhanced since private actors will prefer to avoid ratcheting social gains from innovation increase only if innovation can allow emissions to be more fully priced technology policy is more effective with fuller emissions pricing and is better viewed as a complement to than a substitute for mitigation policy

what explains carbon pricing variation between countries abstract economists generally view carbon pricing as an efficient policy to address externalities from energy use but political feasibility can be a persistent issue this paper aims to comprehensively consider underlying factors contributing to carbon pricing magnitude including environmental social political and economic variables we use the between estimator and focus on exogenous variables to explain continuous carbon pricing variables for a global sample of countries we find that larger coal reserves per capita have a negative effect on the log of the product of carbon price levels and coverage control of corruption is a key governance variable that is positively associated with carbon pricing outcomes another important political dimension is the degree of political globalisation for economic resources there is evidence that larger stocks of domestic credit help to enable carbon pricing there is some evidence that climate change awareness is positively associated with carbon pricing but the proportion perceiving climate change as a serious threat is negatively associated with carbon pricing our global results complement case study approaches that consider carbon pricing design for local contexts

a comparison of the personality type dimensions of the 1987 inc 500 company founders ceos with those of slower growth firms abstract a popular misconception holds that most new businesses experience similar growth stages of start up rapid growth maturity and decline yet business statistics show that only a small number of firms grow into large organizations a few experience some growth but the majority have such small growth that they provide only a marginal income to the founder while market conditions impact on the growth of the firm they do not explain growth differences when they occur under similar market conditions in this paper the authors have compared psychological type preferences of founders ceos of fast growth firms with those of slow growth firms under the assumption that differences in psychological preferences as they relate to gathering assimilating and processing information would have an impact on the strategic or growth orientation of the firm the results are based on the administration of the myers briggs type indicator to the founders cofounders of 143 firms included in the 1987 inc 500 list of the fastest growing private companies in the united states and the comparison of these results with those of an earlier study of 150 founders ceos of successful yet slower growing firms the primary personality traits under consideration were an individual s preferred method of gathering information from the environment making decisions and drawing conclusions from the information the results indicate that founders of rapid growth firms have psychological preferences that are significantly different from those of their slower growth counterparts growth oriented founders prefer an intuitive approach or consideration of future possibilities when gathering information and a thinking or planned and organized approach to drawing conclusions these preferences represent those facets most frequently used in strategic or growth planning investors in new firms that place importance on the capabilities and orientations of the management team as an evaluation criteria are currently limited to consideration of past experiences an awareness of the management team s experiences can provide an indication of management ability but unless their experience involves management of growth the information related to growth propensities or orientations is limited a measure of a person s preferences in gathering assimilating and processing information can indicate their desires for strategic and or growth planning hence investors may have another tool that can be used in the investment decision making process in addition government policy makers may have the opportunity for increased effectiveness in assistance programs by recognizing that the needs and preferences of founders of rapid growth companies are significantly different from those of their slower growing counterparts and that these differences should be considered in the development of assistance programs

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

contracts under wage compression a case of beneficial collusion this paper considers a principal agent model with adverse selection and limited wage discrimination under wage compression an agent may have an incentive to free ride on other agents by manipulating his private information when collusion among the agents is not possible the principal distorts the output schedule to reduce information rent associated with the free riding opportunity under collusion however the principal can reduce the information rent by inducing side contracts among the agents thus partly removing the distortion in the output schedule we show that side contracts among the agents take place in equilibrium and that the prospect of collusion is beneficial

guiding the future energy transition to net zero emissions lessons from exploring the differences between france and sweden abstract despite similarities in their current energy mixes france and sweden s pathways have been very different since the 1970s when both systems were highly dependent on fossil fuels after the oil crisis both countries chose to reduce their oil consumption by developing nuclear power however sweden pursued a more diversified energy policy that has subsequently allowed it to reduce its co2 emissions today both countries have committed to a carbon neutrality goal by 2045 for sweden and 2050 for france in order to understand the key factors that can drive energy transition toward a carbon neutrality goal we propose to compare the past energy transitions in france and sweden two countries that have significantly reduced their co2 emissions and fossil fuel dependency to assess the impacts of the current energy system and its regulations on the feasibility of meeting carbon neutrality we use times bottom up energy system optimization models the results show that france faces more challenges in transforming its energy system than sweden i e an increase in power production a decrease in gas consumption the replacement of heating systems in buildings and the electrification of industry thus confirming that its energy policy has to be driven with a long run perspective

the impacts of the trade liberalization of environmental goods on power system and co2 emissions abstract the trade liberalization of environmental goods eg through as environmental goods agreement ega is crucial in low carbon electricity technology diffusion however there is a big gap of the eg definition lists and the integrated effectiveness analysis of ega this paper analyses the effects of the trade liberalization of eg based on macroeconomic and electricity sector models and attempts to find a more efficient eg trade policy by comparing different eg lists considering end use control and combining the eg policy with a carbon tax the results show that the trade liberalization of eg does not necessarily benefit the environment without other policies as the effects of the multiple end uses of eg on conventional energy might result in environmental damage we find that merging an ega into a global carbon tax system would enhance the effects of carbon tax on co2 reduction by 33 and simultaneously lower the gdp loss due to the carbon tax by 75 the economic benefits from the ega could offset the costs of other environmental policies thus end use control and other environmental policies should be considered at both the global and regional levels in the setting of international trade agreements that target eg

a public choice view on the climate and energy policy mix in the eu how do the emissions trading scheme and support for renewable energies interact abstract in this paper we analyze the rationale for an energy policy mix when the european emissions trading scheme ets is considered from a public choice perspective that is we argue that the economic textbook model of the ets implausibly assumes 1 efficient policy design and 2 climate protection as the single objective of policy intervention contrary to these assumptions we propose that the ets originates from a political bargaining game within a context of multiple policy objectives in particular the emissions cap is negotiated between regulators and emitters with the emitters abatement costs as crucial bargaining variable this public choice view yields striking implications for an optimal policy mix comprising res supporting policies whereas the textbook model implies that the ets alone provides sufficient climate protection our analysis suggests that support for renewable energies 1 contributes to a more effective ets design and 2 may even increase the overall efficiency of climate and energy policy if other externalities and policy objectives besides climate protection are considered thus our analysis also shows that a public choice view not necessarily entails negative evaluations concerning efficiency and effectiveness of a policy mix

dominant strategy implementation of bayesian incentive compatible allocation rules abstract a large literature on incentive mechanisms represents incentive constraints by the requirement that truthful reporting be a bayesian equilibrium this paper identifies mechanism design problems for which there is no loss in replacing bayesian incentive compatibility by the stronger requirement of dominant strategies we identify contexts where it is possible to change the transfer payments of an optimal bayesian mechanism so as to create dominant strategies and yet leave every participant s expected utility unchanged we also address the issue of multiple equilibria and unique implementation contexts where these results apply include auctions bilateral bargaining procurement contracting and intrafirm resource allocation

research on a single policy or policy mix in carbon emissions reduction abstract existing literature on the optimal type of carbon mitigation policy and whether it is better to apply a policy mix instead of a single policy is still unclear this paper assesses the policy effectiveness under exogenous shocks by applying a dynamic stochastic general equilibrium dsge model comparing the differences between the carbon mitigation and economic impacts of a policy mix versus a single policy carbon tax or carbon trading scheme the results showed that energy demand is rigid in response to technological shocks therefore there is no significant difference for the energy consumption related carbon emissions in response to the technological progress under three different policy scenarios a carbon tax scenario i a carbon trading scheme scenario ii and a carbon policy mix scenario iii overall carbon emissions policy has a negative impact on the economy compared to the other two policies a carbon trading scheme has a relatively slight impact on the economy a mandatory carbon price would have a more significant impact than would a market based carbon price the policy mix formed by a carbon tax and a carbon trading is comprehensive in terms of both price flexibility and coverage scope

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

the evolution of new technology ventures over 20 years patterns of failure merger and survival abstract relatively few studies of entrepreneurs have examined the evolution of business ventures over a long period of time this paper summarizes the fate of 250 technology based companies founded in northern california during the 1960s the three outcomes studied are failure merger and continued operation in addition interviews with a dozen founders of firms that survived the entire 20 year period shed light on the founders own interpretations of why they succeeded by 1988 50 of the firms in the sample had failed 32 had merged or been acquired and 18 had survived as independent businesses there was a steady and occasionally sharp erosion in the number of survivors throughout the period a striking finding was that fully 78 of the surviving firms in 1988 still had one or more of the original founders in place among the factors predicting failure were product market problems such as product timing difficulties problems of product design or inappropriate distribution channels financial difficulties such as initial undercapitalization or problems with the venture capital relationship and managerial key employee problems such as imbalance in the management team or succumbing to the trappings of success the firms in the data base which were subsequently merged or acquired exhibited a number of macro and micro characteristics from a macro point of view the merger acquisition rates seem to have been lower than the national rate in the late 1960s higher in the later 1970s and similar in the 1980s from a micro point of view discernible patterns existed among acquired firms such as size and year since founding interviews with surviving founders suggested that relations between founders banking and credit problems attempted takeovers and international expansion were among the key crises that had to be overcome by the surviving firms of particular interest was the diversity of motives for founding the business reported by the survivors in addition to the desire to achieve wealth or to be independent we heard mentioned loyalty to a product or technology which would otherwise disappear and commitment to satisfying a customer group also noted were founders who indicated that their career as an entrepreneur came about primarily by accident five themes emerging from the interviews were characterized by the surviving founders as business lessons learned 1 know yourself 2 love your product 3 honor your customer 4 treat your people well and 5 keep your integrity the interviews in conjunction with the data on surviving firms are useful in expanding our understanding of the type of person that starts a business and why some start ups succeed over the long term particularly noteworthy is the number affirms who survived without ever growing larger theories of long term entrepreneurial success may need to take risk aversion into account

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

willingness to pay and policy instrument choice for climate change policy in the united states abstract this paper provides the first willingness to pay wtp estimates in support of a national climate change policy that are comparable with the costs of actual legislative efforts in the u s congress based on a survey of 2034 american adults we find that households are on average willing to pay between 79 and 89 per year in support of reducing domestic greenhouse gas ghg emissions 17 by 2020 even very conservative estimates yield an average wtp at or above 60 per year taking advantage of randomized treatments within the survey valuation question we find that mean wtp does not vary substantially among the policy instruments of a cap and trade program a carbon tax or a ghg regulation but there are differences in the sociodemographic characteristics of those willing to pay across policy instruments greater education always increases wtp older individuals have a lower wtp for a carbon tax and a ghg regulation while greater household income increases wtp for these same two policy instruments republicans along with those indicating no political party affiliation have a significantly lower wtp regardless of the policy instrument but many of these differences are no longer evident after controlling for respondent opinions about whether global warming is actually happening

reciprocal supervision collusion and organizational design we study the design of supervisory functions in an organization with one principal and two agents each agent can perform supervision activities regarding the other agent we characterize the way the principal must structure incentive payments to avoid any collusive activity between agents in particular it is shown that better mutual information between agents may hurt the principal the other main result is the possibility that it may be better to give up one supervisory function or to have a third party be the supervisor if possible finally we show that such a dual supervisory structure raises the possibility that letting collusion happen may be the best policy
