why you can t find a taxi in the rain and other labor supply lessons from cab drivers i replicate and extend the seminal work of camerer et al labor supply of new york city cabdrivers one day at a time quarterly journal of economics 112 1997 407 441 who find that the wage elasticity of daily hours of work for new york city taxi drivers is negative and conclude that their labor supply behavior is consistent with reference dependence in contrast my analysis of the complete record of all trips taken in nyc taxi cabs from 2009 to 2013 shows that drivers tend to respond positively to unanticipated as well as anticipated increases in earnings opportunities additionally using a discrete choice stopping model the probability of a shift ending is strongly positively related to hours worked but at best weakly related to income earned i find substantial heterogeneity across drivers in their elasticities but the estimated elasticities are generally positive and rarely substantially negative i find that new drivers with smaller elasticities are more likely to exit the industry whereas drivers who remain quickly learn to be better optimizers have positive labor supply elasticities that grow with experience these results are consistent with the neoclassical optimizing model of labor supply and suggest that consideration of gain loss utility and income reference dependence is not an important factor in the daily labor supply decisions of taxi drivers jel codes d01 d03 j22

environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

beyond the question does it pay to be green how much green and when abstract this research investigates the relationship between green management and performance in italian firms the analysis compares innovation and productivity of firms with similar features but different environmental activities firms are matched on a rich set of covariates extending the coarsened exact matching to survey data matched data are analysed with parametric and non parametric tests and endogenous treatment regression the analysis shows that the relationship between green management and performance is u shaped green firms are performing no better than firms with no environmental activity especially in energy intensive sectors among green firms more advanced environmental management is associated with higher performance overall the results suggest that green management has strong sectoral patterns and no linear relationship with performance findings suggest that green managers should pursue a comprehensive environmental management system sectoral specific policies to promote environmentally friendly activities are needed when green activities are not paying off

a theoretical foundation of the porter hypothesis abstract this letter shows that by reducing agency costs an environmental regulation may enhance pollution reducing innovation while at the same time increasing firms private benefit

assessing the relationship between economic and ecological performance distinguishing system levels and the role of innovation in this article we critically discuss the different perspectives that are currently in use for assessing the relationship between ecological and economic performance based on a review of the literature we propose that research up till now has made use of four distinct system boundaries the firm markets production and consumption systems and economic systems making these boundaries explicit is helpful in interpreting the mixed results that have been obtained we describe the consequences of the choice for each of these system boundaries and look at implications for innovation we also argue that the production and consumption system boundary offers potential for further advances in the field and deserves more attention in future research

overcoming scarcities through innovation what do technologists do when faced with constraints abstract the question that still divides many debates about sustainability is the possibility of technological substitution of scarce natural resources while there is considerable debate among economists whether technology can mitigate scarcities through development of substitutes there is little actual research on the mechanisms and limitations of this substitution process in this study i seek to build a bridge between scarcity and innovation literatures to study when technologists decide to develop technological substitutes my starting point is the theory of technology as a recombination of existing mental and physical components combining this theory with modern scarcity literature that differentiates between absolute relative and quasi scarcities yields a more nuanced framework for understanding both different types of scarcities and how technologists decide whether or not to develop or adopt technological substitutes this improves our understanding of the possibilities and limitations of scarcity induced innovation i then illustrate the use of this framework with two brief historical case studies about constraint induced innovation i conclude that the mainstream economic practice of assuming that substitution will occur automatically even in cases of absolute scarcity may hide extremely important phenomena from discussion and debate behind a veil of circular reasoning

the cost of regulation osha epa and the productivity slowdown the slowdown in productivity growth in the u s economy during the 1970 s has been a matter of great concern to policymakers associated as it is with inflation unemployment and declining real wage growth this paper examines the impact on productivity growth of government regulation specifically worker health and safety regulation by the occupational safety and health administration osha and environmental regulation by the environmental protection agency epa looking at data for 450 manufacturing industries between 1958 and 1978 the study finds a large negative relationship between such regulation and productivity growth using these results about 30 percent of the decline in productivity growth in manufacturing during the 1970 s may be attributed to such regulation several previous studies have looked at the contribution of regulation to the productivity slowdown many of these have inferred that the contribution must be small on the basis of the relatively small amount spent on complying with such regulations edward denison 1979 estimates that only about 16 percent of the productivity slowdown in the 1972 75 period was due to regulation 35 percentage points out of a slowdown of 2 17 percentage points paul portney 1981 notes that little of gnp is spent on pollution control under 2 percent concluding that therefore pollution regulations could have little effect on productivity growth norsworthy et al 1979 also find a small impact of pollution abatement capital expenditures on productivity growth studies based on econometric estimation of the regulation productivity relationship have found a wide range of results gregory christainsen and robert haveman 1981 find regulation reduced labor productivity growth by 27 percentage points using time series data and measures of total federal regulation robert crandall 1981 finds a strong relationship between pollution abatement capital and productivity growth but this relationship disappears when a measure of energy intensity is included robin siegel 1979 observes a significant contribution 5 percentage points from pollution control expenditures to the productivity slowdown for 1965 73 but not for later years finally frank gollop and mark roberts 1983 examine data for a set of electric utilities and find that regulation of emissions had a large impact on total factor productivity growth lowering it for regulated firms by 59 percentage points many other factors might help to explain the productivity slowdown including the rise in energy prices the long and severe recession and declines in research and development expenditures there have been a variety of studies examining the contributions of each factor to the slowdown they generally conclude that many factors contributed to the slowdown but that a sizable fraction of the slowdown remains unexplained by the estimated contributions of all the factors considered

macro economic and development indexes and iso14001 certificates a cross national analysis abstract environmental management systems emss implemented according to the iso14001 standard have been examined by many authors especially focussing on its impact at the firm level however only a few papers have investigated the impact of iso14001 from a country perspective this paper aims to contribute to bridging this gap the aim is to study the relation between iso14001 growth and the trend in selected macro economic and development indexes by applying the growth mixture model to a panel of 73 countries for the period 1999 2012 we assess the following hypotheses a the increase in numbers of iso14001 certifications corresponds to an increase in economic indexes b the increase in iso14001 corresponds to an increase in development indexes c the trends of iso14001 adoption and macro economic indexes confirm the relationship described by the environmental kuznets curve the results confirm a positive relation among the trends of some variables such as iso14001 and gross domestic product gdp iso14001 and industry value added while no significant results were found when observing the relation between iso14001 and the selected development indexes in addition using the industry added value as the variable to measure economic development our results support the theory of the environmental kuznets curve

sustainability in a post keynesian growth model for an open economy the paper expands the bop constraint growth model and kaldorian regimes productivity and demand regimes in order to include some of the concerns raised by ecological economics in post keynesian models for open economies the demand regime is modified by taking into account porter s hypothesis which suggests that environmental innovations spurred by environmental policies can foster competitiveness as a result the equilibrium bop constrained rate of growth increases leading to a different version of thirlwall s law which opens room for analyzing the impact of environmental innovations on convergence between developing and developed economies the productivity regime in turn considers the growth and employment implications of innovations in labor productivity standard innovations and environmental efficiency environmental innovations it is argued that the fiscal policy and composition of public expenditure matter for long run growth employment and sustainability

the potential of environmental regulation to change managerial perception environmental management competitiveness and financial performance abstract this research presents an overview of where the gaps in the literature exist in relation to the link between environmental regulation and proactive environmental management and competitiveness and incorporates them in a whole model different papers have highlighted only partial aspects of these relationships specifically this research evaluates the relationship between managerial perception and the different styles of environmental regulations command and control versus voluntary norms the mediator role of environmental management in the link between environmental regulations and competitiveness the effect of competitiveness on financial performance and the two way relationship between proactive environmental management and financial performance finally this paper uses statistical evidence to test and estimate causal relationships through a structural equation modelling of 208 firms affected by ippc law in spain there is a lack of systematic statistical evidence on this topic in the literature which mainly focuses on case studies the results show that when environmental regulation stems from command and control legislation its influence on managerial perception and proactive environmental management is not significant however when environmental regulation stems from voluntary norms its effects are positive moreover investment in proactive environmental management contributes to increasing the competitiveness of the firm cost and differentiation competitive advantage have a positive impact on financial performance finally the link between proactive environmental management and financial performance may follow different paths 1 neither direct nor single because it can depend on competitive advantage and 2 direct because there is a significant two way relationship between these variables proactive environmental management influences financial performance and financial performance influences proactive environmental management

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 impact of standards and regulation on innovation in uncertain markets abstract this study analyses the impact of formal standards and regulation on firms innovation efficiency considering different levels of market uncertainty we argue that formal standards and regulation have different effects depending on the extent of market uncertainty derived from theoretical considerations about information asymmetry and regulatory capture our empirical analysis is based on the german community innovation survey cis the results show that formal standards lead to lower innovation efficiency in markets with low uncertainty while regulations have the opposite effect in cases of high market uncertainty we observe that regulation leads to lower innovation efficiency while formal standards have the reverse effect our results have important implications for the future application of both instruments showing that their benefits heavily depend on the market environment

international investment location decisions abstract in international location tournaments governments compete for foreign investment with tax and other short run incentives such tournaments can be won if agglomeration economies are sufficiently powerful to overcome investors desire to spread investments as a hedge against risk we focus on manufacturing investments by u s multinationals in the 1980s our econometric results suggest that agglomeration economies are indeed the dominant influence on investor calculations paradoxically short run incentives have limited apparent impact on location choice we conclude that high cost tournament play is unnecessary for countries with good infrastructure development specialized input suppliers and an expanding domestic market

information processing and organizational structure abstract standard economic theories of the firm and other organizations stress profit maximization as the foundation for derivation of predictable behavior yet statistical and case study evidence continues to accumulate that real firms do not act as required by the neoclassical framework instead of being represented by ever more elaborate maximization models the firm can be modeled simply as a network of information processing agents the actions of the firm are then a function only of the network structure and the information processing capabilities of the agents this approach can be used to explain a number of features of organizational behavior including the process of technological diffusion it also suggests that derivation of the optimal organizational structure may be computationally complex with a number of implications for economic theory and policy development

measuring environmental policy stringency approaches validity and impact on environmental innovation and energy efficiency abstract solid tests of the impact of environmental and energy policy on important economic outcomes such as innovation productivity competitiveness and energy and carbon efficiency are impaired by the lack of appropriate empirical proxies for the commitment to and stringency of environmental policy we contribute to the literature by 1 computing different indicators of environmental policy stringency 2 testing to what extent they convey similar insights through a statistical comparison exercise and 3 showing the implications of using one or the other indicator in two illustrative empirical applications focused on environmental innovation and energy efficiency we conclude by highlighting the implications of our analysis for empirical research focusing on the evaluation of policy impacts and highlight fruitful future research avenues

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd

the effect of environmental regulation on the locational choice of japanese foreign direct investment this article assesses the impact of environmental regulation er in host countries on japanese foreign direct investment fdi decision making it tests the pollution haven hypothesis using data on national er standards and japanese inward fdi in five dirty industries iron and steel industry nonferrous metals industry chemicals industry paper and pulp industry nonmetallic products industry the results do not support the pollution hypothesis on the contrary inward japanese fdi appears to be attracted to countries which have committed themselves to a transparent and stable environment regulatory environment suggesting that the quality of the regulatory framework in terms of its certainty and transparency has a greater influence on foreign investors choice of location than the level of environmental regulatory measures

an analysis of the climate change architecture abstract this paper examines the complexity of the current negotiations to avert climate change under the united nations framework convention on climate change drawing on economic game theory modelling it interprets the latest developments within the international negotiations and provides a political economy analysis of the climate change architecture it places the pursuit of international co operation via the kyoto protocol s second commitment period in the context of a country s maintenance of national interest and a flexible emissions abatement strategy accepting that countries will reject an international agreement or obligation that is seen as inimical to their economic competitiveness it incorporates a new game theory model considers how learning from such models can influence agreement design and proposes a new approach from a non monotonic polluting payoff function attention is placed on enabling conditions that entice countries to ratify a climate agreement thereby encouraging participation and accelerating a near term deployment of low carbon technologies

the efficiency paradox bureaucratic and organizational barriers to profitable energy saving investments abstract the paradox of why profitable energy saving investments are not undertaken continues to provoke debate the underlying phenomenon might be called the efficiency paradox because it represents a case in which business firms which are often presumed or taken axiomatically to be economically efficient make decisions that do not maximize profits new data from one of the us environmental protection agency s voluntary pollution prevention programs enables this paradox to be explored statistically the data show that both the level and variation in returns to lighting upgrade investments cannot be explained by standard economic models substantial gains in energy efficiency can be achieved without sacrificing profitability both economic and organizational factors account for some of the variation in observed returns to these investments but the results suggest a need for improved and more comprehensive theories of the investment behavior of firms and other organizations

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

model of efficient and sustainable improvements in a lean production system through processes of environmental innovation abstract globalization has changed the world as well as how a customer judges the value of a product which has created a new business focus different approaches have been oriented on this direction such as the lean manufacturing system and the concept of sustainability however these two notions are not easy to implement simultaneously besides several authors have declared doubts with respect to reaching this target difficulty persists in identifying the tools required and quantifying the improvements achieved this research develops a general approach based on environmental innovation to help firms harmonize efficiency and sustainability the goal is to add extra value to the product which provides the potential to enhance competitiveness in the 21st century globalized market a case study demonstrates that the costs the incomes the social responsibility and the sustainability can be improved when environmental innovation is applied transforming the traditional production system into a lean system

new york city cab drivers labor supply revisited reference dependent preferences with rational expectations targets for hours and income this paper reconsiders whether cabdrivers labor supply decisions reflect reference dependent preferences following botond koszegi and matthew rabin 2006 we construct a model with targets for hours as well as income both determined by rational expectations estimating using henry s farber s 2005 2008 data we show that the reference dependent model can reconcile his 2005 finding that drivers stopping probabilities are significantly related to hours but not income with the negative wage elasticity of hours found by colin camerer et al 1997 and farber 2005 2008 the model yields sensible estimates that avoid farber s 2008 criticism that drivers income targets are too unstable to allow a useful reference dependent model of labor supply

is tomorrow another day the labor supply of new york city cabdrivers the labor supply of taxi drivers is consistent with the existence of intertemporal substitution my analysis of the stopping behavior of new york city cabdrivers shows that daily income effects are small and that the decision to stop work at a particular point on a given day is primarily related to cumulative daily hours to that point this is in contrast to the analysis of camerer et al who find that the daily wage elasticity of labor supply of new york city cabdrivers is substantially negative implying large daily income effects this difference in findings is due to important differences in empirical methods and to problems with the conception and measurement of the daily wage rate used by camerer et al

a free lunch in the commons we derive conditions under which raising costs through a regulatory constraint or a fully expropriated tax can increase the profits arising from a common pool resource the basic model assumes a fixed number of identical agents with linear costs selling in a single period at an exogenous price a necessary and sufficient condition for a cost increase to be profitable is that aggregate output from the resource be locally convex in aggregate effort we also show that cost increases can be profitable even if price is endogenous agents are heterogeneous entry is costless or agents are playing a markov perfect equilibrium of a dynamic game we also discuss more general welfare implications of the result along with its relation to existing results for a cournot oligopoly

is environmental efficiency trade inducing or trade hindering abstract global efforts to identify strategies for sustainable economic growth and development underline the need for understanding important links between environmental policies and international trade in this paper by constructing an environmental efficiency index for 111 countries from 1980 to 2009 we are able to empirically test for one such link an improvement in the environmental efficiency index in terms of carbon dioxide emissions reflects a decrease in the cost of efforts to mitigate the environmental costs associated with growth countries that improve their environmental efficiency are found to experience strong international trade effects both through increased exports and increased imports while the positive link between efficiency improvements and exports is supportive of the porter hypothesis the positive link between efficiency improvements and imports is supportive of strong positive income effects on account of environmental efforts these results which are robust to alternative estimation strategies lend strong support to global efforts to improve countries environmental efficiencies

learning together growing apart global warming energy policy and international trust abstract standard models of uncertainty in economics imply that sharing information can reduce uncertainty and help identify welfare improving policies in international relations epistemic communities of scientists are thought to help provide information for these purposes however conflicting preferences can frustrate the transmission of information and prevent effective information sharing in addition opportunities for information sharing can deepen distrust as actors observe each other s reaction to what to them is credible information a model that assumes uncertainty both about the state of the world and the parties motivations is applied to international climate change negotiations

regulatory taxation of fossil fuels theory and policy abstract research on energy taxation is often based on purely theoretical deductions this paper stays closer to the real world using empirical data and interpreting results in a political economic setting of risk and uncertainty economic growth in developing countries will boost energy demand increasing the risk of shortages of oil and natural gas half way through the next century and of coal towards the year 2100 furthermore there is mounting evidence that emissions of co 2 trigger harmful climate changes a timely introduction of regulatory taxes will reduce demand for fossil fuels and accelerate the introduction of sustainable technology the empirical results presented show moreover that such taxes may claim a substantial part of the rent on energy extraction for the energy importing countries it is argued that optimal control and the avoidance of displacement effects require a tax affecting marginal use with exceptions to safeguard competitive positions exceptions may be scaled down as the jurisdiction is enlarged

pollution havens and the trade in toxic chemicals evidence from u s trade flows national registries of toxic chemical emissions and facilities are increasingly used to raise public awareness of potential health hazards in local areas but an unintended consequence may be the offshoring of production to less regulated countries using disaggregated u s trade data this study examines the impact of registry listing on subsequent bilateral trade flows estimates from a difference in differences model indicate a significant shift toward imports from poorer countries following registry listing assuming that environmental protection is a normal good this result suggests the emergence of pollution havens due to more stringent u s environmental regulation

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

total factor carbon emission performance of fossil fuel power plants in china a metafrontier non radial malmquist index analysis article i nfo this paper proposes the metafrontier non radial malmquist co2 emission performance index mnmcpi for measuring dynamic changes in total factor co2 emission performance over time the mnmcpi method allows for the incorporation of group heterogeneity and non radial slack into the previously introduced malmquist co2 emission performance index mcpi we derive the mnmcpi by solving several non radial data envelop ment analysis dea models we decompose the mnmcpi into an efficiency change ec index a best practice gap change bpc index and a technology gap change tgc index and based on the proposed indices we examine the dynamic changes in co2 emission performance and its decomposition of fossil fuel power plants in china for the 2005 2010 period the empirical results show a 0 38 increase in total factor co2 emission performance as a whole and a u shaped mnmcpi curve for the sample period because companies owned by the central government lack innovation and technological leadership the results suggest a missing link in the role of the central government in promoting co2 emission performance

corporate social responsibility and corporate performance evidence from a panel of us listed companies we investigate whether inclusion and permanence in the domini social index dsi affects corporate performance on a sample of around 1000 firms in a 13 year interval by controlling for size industry business cycle and time invariant firm idiosyncratic characteristics our results find partial support to the hypothesis that corporate social responsibility is a move from the shareholders wealth to a multi stakeholders welfare target on the one side permanence into the domini index di is shown to increase reduce significantly total sales per employee returns on equity but not when large and r d investing firms are excluded from the sample on the other side lower returns on equity for domini firms seem nonetheless to be accompanied by relatively lower conditional volatility and lower reaction to extreme shocks with respect to the control sample an explanation for these findings suggested by the inspection of domini criteria is that social responsibility implies on the one side decisions leadi

total factor carbon emission performance of the chinese transportation industry a bootstrapped non radial malmquist index analysis this paper proposes a non radial malmquist co2 emission performance index nmcpi for measuring dynamic changes in total factor co2 emission performance over time this index enables the consideration of non radial slacks in the conventional malmquist co2 emission index mcpi the nmcpi is calculated based on a non radial directional distance function derived by several data envelopment analysis dea models furthermore nmcpi could be decomposed into an efficiency change ec index and technological change tc index a bootstrapping approach is conducted to introduce statistical inferences into the nmcpi and its decompositions based on the proposed indices the dynamic co2 emission performance change and its decompositions of the chinese regional transportation industry from 2002 to 2010 are investigated the empirical results demonstrate that the total factor carbon emission performance of the transportation industry as a whole decreased by 32 8 over the period and this reduction was primarily caused by technological decline

understanding developing country stances on post 2012 climate change negotiations comparative analysis of brazil china india mexico and south africa abstract an essential issue in future climate negotiations is how to bring developing countries on board this paper proposes and applies the two level interest based model to analyze the factors that affect the likely stances of the plus five countries brazil china india mexico and south africa on international climate negotiations this study finds mitigation capability to be a crucial factor which consists of at least such sub factors as per capita income energy endowment and economic structure while ecological vulnerability does not seem to play an important role which includes reductions in agricultural outputs sea level rise climate related natural disasters and others the paper proposes six options in an ascending order of stringency that the plus five are likely to adopt the paper suggests that the basic four the plus five excluding mexico particularly china and india are less likely to adopt a voluntary commitment to an emissions cap on the national economy in the near future than mexico which has the highest mitigation capability among all five the basic four are likely to adopt more stringent climate polices with increasing mitigation capabilities suggesting the importance of effective international financial and technology transfer mechanisms and further tighten emission reduction targets from developed countries

can a carbon trading system promote the transformation of a low carbon economy under the framework of the porter hypothesis empirical analysis based on the psm did method abstract global warming is one of the issues of great concern in the world the large scale use of fossil fuels has led to the continuous increase in carbon emissions resulting in global energy shortages and environmental pollution reasonable and strict environmental regulation promotes technological innovation by enterprises to achieve a win win situation between the economy and environment which is the core idea of the porter hypothesis the choice of china as the world s largest energy consumer and carbon emitter is not only related to the country s own mode of economic growth but also determines the development of the world s low carbon economy we used the panel data from 2000 to 2016 of 30 provincial level administrative regions in china and adopted the propensity score matching difference in differences method to test the impact of china s carbon trading pilot system on the transformation of a low carbon economy the empirical results show that under the constraints of the established resources and environment there is a positive relationship to some extent between china s carbon trading system and low carbon economic transformation this relationship can realize the win win situation of environmental and economic benefits as advocated by the porter hypothesis and further verify the applicability of the porter hypothesis

the effects of deregulation de unionization technology and human capital on the work and work lives of truck drivers this paper investigates the sources of wage decline among truck drivers the authors first present an overview of the work and work life of truck drivers and then take two complementary approaches to disentangling the forces that reduced driver earnings the earnings of truck drivers fell by 21 between 1973 and 1995 using current population survey data the authors find that deregulation accounted for one third of the decline in drivers wages with a larger negative effect for non union workers the other two thirds of the decline was due to economic forces that broadly affected the blue collar economy using unique survey data the authors explore the effects of factors frequently cited as sources of blue collar wage decline this analysis indicates that only one new technology satellite communication systems had meaningful effects on drivers earnings which rose as a consequence of superior efficiency and work intensification union membership remains an important determinant of wages the authors conclude that the primary sources of wage decline and increased wage inequality have been deregulation de unionization and a declining manufacturing wage

taxing variable cost environmental regulation as industrial policy abstract conventional wisdom has it that a country that enacts strict environmental regulations will place its firms at a competitive disadvantage this view has been challenged recently some commentators argue that stricter regulation will enhance domestic competitiveness strict regulations induce innovation we evaluate this argument in a strategic trade model in very special cases a strengthening of regulation may result in a shift of profits from foreign to domestic firms this is not a general result however environmental regulation should of course be imposed to control externalities but it is unlikely that it will serve to generate industrial advantage

comparing systems approaches to innovation and technological change for sustainable and competitive economies an explorative study into conceptual commonalities differences and complementarities this paper makes a distinction between three theoretical frameworks that have been highly influential in the discourse on innovation competitiveness and sustainability sectoral systems of innovation ssi technological innovation systems tis and socio technical systems st systems these frameworks share a common systems approach to innovation but are often positioned as different bodies of literature that correspond to different epistemic communities this paper is explorative and conceptual in nature it presents a systematic comparative review of ssi tis and st systems based on the following analytical dimensions 1 system boundaries 2 actors and networks 3 institutions 4 knowledge 5 dynamics and 6 policy approach in the concluding section commonalities and differences of the three approaches are presented and suggestions for complimentarily are made c 2010 elsevier ltd all rights reserved

game theory and climate diplomacy abstract starting with the new periodic table npt of 2 2 order games introduced by robinson and goforth 2005 we provide an exhaustive treatment of the possible game theoretic characterizations of climate negotiations between two players e g great powers or coalitions of states of the 144 distinct 2 2 games in which the players have strict ordinally ranked utilities 25 are potentially relevant to climate problem the negotiations may be characterized as a no conflict game prisoner s dilemma coordination game chicken type game or cycle depending on the payoff matrix which game corresponds to the actual state of the world depends both on the severity of risks associated with climate change and the perceptions of the governments engaged in the negotiations nash equilibrium or maxi min equilibrium or neither may be the outcome achieving universal abatement of greenhouse gas emissions may require side payments or enforcement mechanisms outside the game framework but we show how the negotiations themselves may offer opportunities to select between nash equilibria or alter the payoff rankings and strategic choices of the players in particular scientific information pointing to the severity of the risks of climate change suggests characterization of the negotiations as a coordination game rather than a prisoner s dilemma

collective bargaining after deregulation do the teamsters still count using data from the american trucking associations and a 1991 telephone survey of 223 major firms in the general freight segment of the trucking industry sic 4213 the author describes the restructuring of the trucking industry that occurred following economic deregulation that began in 1977 and examines how that restructuring affected industrial relations outcomes such as wages and union strength he finds that both market concentration and competition increased after 1977 he also concludes that regulatory restructuring led the general freight industry to divide into two sectors one handling full truckload shipments shipments of 10 000 pounds or more and one handling less than truckload shipments the teamsters union lost bargaining power in the truckload sector but it retained much of its bargaining power within the less than truckload sector

should the personal computer be considered a technological revolution evidence from u s metropolitan areas the introduction and diffusion of personal computers are widely viewed as a technological revolution using u s metropolitan area level panel data this paper asks whether links between pc adoption educational attainment and the return to skill conform to a model of technological revolutions in which the speed and extent of adoption are endogenous the model implies that cities will adjust differently to the arrival of a more skill intensive means of production with the returns to skill increasing most where skill is abundant and its return is low we show that the cross city data fit many of the predictions of the model during the period 1980 2000 the pc diffusion era

drivers of disruption estimating the uber effect abstract a frequent belief is that the rise of so called gig work has led to the displacement of workers in a wide range of traditional jobs this paper examines the impacts of the flagship of the gig economy uber on workers employed in conventional taxi services our analysis exploits newly collected data on the staggered rollout of uber across metropolitan areas in the united states and a difference in differences design to document that incumbent taxi drivers experienced a relative earnings decline of about 10 percent subsequent to uber s entry into a new market while there are no significant effects on their labor supply additional evidence from a battery of placebo tests event study estimates and specifications using google trends data to capture differences in treatment intensity underlines these findings a triple differences design that compares changes among taxi drivers relative to bus tractor and truck drivers that were unaffected by the arrival of uber provides further supporting evidence that the diffusion of uber has reduced the earnings potential of incumbent drivers in conventional taxi services in the united states

the institutionalisation of trust in the international climate regime abstract in the extensive literature on international environmental co operation trust is usually treated in terms of compliance and verification mechanisms on the assumption that there will always be incentives for parties to international agreements to cheat or to free ride indeed the establishment of adequate assurances that such behaviour will be detected and punished is frequently the sine qua non of agreement in the first place technical and legal compliance mechanisms have developed rapidly in environmental treaty making over the last two decades the climate regime is no exception and its provisions in this regard are briefly described and analysed however it will be argued that the development of trust amongst the parties goes well beyond formal compliance and depends upon the institutionalised relationships often amongst officials and technical experts that have grown up since the negotiations for a climate treaty commenced in the late 1980s

extended producer responsibility instruments and innovation in eco design an exploration through a simulation model abstract this paper presents an agent based simulation model that models both economical and physical relations between firms recyclers and consumers this framework allows an investigation into the connection between physical environmental variables waste flows virgin material flows and economic decisions of agents in the product chain i e firms innovation strategies consumers choices and development of recycling activities the paper highlights the value of using agent based modeling as an operational tool to investigate the effect of waste prevention policy on economic and technological decisions of agents we focus on three types of extended producer responsibility epr instruments which are recycling fees tax subsidy and norms the simulation results show that the impact of each instrument depends on the policy design in particular on the level of stringency and on the reward system which is implemented we show that only tax subsidy systems and stringent norms can lead to radical innovations and to significant changes in product designs in the case of tax subsidy the impact relies more on an innovation effect while in the case of norm it mainly relies on a selection effect

renewable energy and employment in germany abstract the positive impacts of an increasing share of renewable energy on the mitigation of climate change as well as on the decrease of the dependency of energy imports are indisputable however one persistent problem for the german economy has been its high level of unemployment in the recent past therefore any policy strategy will be measured also by its net impact on the labor market the paper describes the results of a study that models this impact and is novel within three respects firstly an input output vector for the renewable energy sector was developed based on the results of more than 1000 interviews with an extensive questionnaire secondly gross and net effect of two different policy scenarios for germany until 2030 were calculated and thirdly the approach varies from earlier studies by its explicit modeling of export and foreign trade effects

the environmental consequences of trade evidence from subnational trade flows abstract the debate over the environmental consequences of free trade is not only quite heated but also entails significant policy ramifications recently cross sectional analysis at the country level has made use of exogenous determinants of trade to identify the causal effect of trade on the environment finding moderate evidence of a beneficial impact of expanded trade on environmental quality given the stakes involved we revisit this finding using subnational data on trade flows across us states and several measures of pollution not only does the analysis shed further light on the debate at the international level but also addresses a heretofore unexamined question does greater inter regional commerce at the subnational level harm the environment our findings are striking providing further evidence against a negative environmental impact of trade for the majority of measures analyzed however several sources of heterogeneity arise that are noteworthy

a new global deal on climate change a global target of stabilizing greenhouse gas concentrations at between 450 and 550 parts per million carbon dioxide equivalent ppm co2e has proven robust to recent developments in the science and economics of climate change retrospective analysis of the stern review 2007 suggests that the risks were underestimated indicating a stabilization target closer to 450 ppm co2e climate policy at the international level is now moving rapidly towards agreeing an emissions pathway and distributing responsibilities between countries a feasible framework can be constructed in which each country takes on its own responsibilities and targets based on a shared understanding of the risks and the need for action and collaboration on climate change the global deal should contain six key features i a pathway to achieve the world target of 50 per cent reductions by 2050 where rich countries contribute at least 75 per cent of the reductions ii global emissions trading to reduce costs iii reform of the clean development mechanism to scale up emission reductions on a sectoral or benchmark level iv scaling up of rd v an agreement on deforestation and vi adaptation finance

efficiency gains within firms under voluntary environmental initiatives this paper focuses on efficiency gains that voluntary environmental initiatives may achieve within the firm current debate concerning the extent and significance of inefficiencies within firms is critically important to the progress of energy and environmental policies several recent lines of inquiry in microeconomics help explain the persistence of inefficiencies within firms in addition two of the most prominent new approaches in the field of business strategy resource based strategy and the capabilities perspective focus on the heterogeneity among firms and the resulting pockets of inefficiency within firms they suggest at least three generic strategies for voluntary environmental initiatives challenging outdated organizational routines creating opportunities for differentiation or complementing firms resource investment trajectories these generic approaches suggest that there is considerable scope for further experimentation with voluntary environmental initiatives

does host market regulation induce cross border environmental innovation this paper evaluates the effect of host country environmental policy stringency on the offshoring of environmental patents for 2000 top world r d performers it is shown that a more stringent environmental regulation triggers both the extensive and intensive margin of patent offshoring in the field of environmental technologies results are robust to various different specifications alternative definitions of innovation offshoring and of regulation restrictions and to the consideration of possible endogeneity of regulation it is suggested inter alia that r d subsidies and non market based regulatory measures are more important than market based instruments as drivers of cross border environmental innovation length 26 pages

the value of flexible work evidence from uber drivers technology has facilitated new nontraditional work arrangements including the ride sharing company uber uber drivers provide rides anytime they choose using data on hourly earnings and driving

the reputational penalties for environmental violations empirical evidence abstract this paper examines the sizes of the fines damage awards remediation costs and market value losses imposed on companies that violate environmental regulations firms that violate environmental laws suffer statistically significant losses in the market value of firm equity the losses however are of similar magnitudes to the legal penalties imposed and in the cross section the market value loss is related to the size of the legal penalty thus environmental violations are disciplined largely through legal and regulatory penalties not through reputational penalties

trucking deregulation and labor earnings is the union premium a compensating differential this article examines wage determination among union and nonunion truck drivers using the 96 monthly current population surveys for 1983 90 union density in the previously regulated for hire sector of the trucking industry fell from about 60 during the regulatory period of the 1970s to about 25 by 1990 union log wage premiums fell from 0 40 in the 1970s to 0 30 or below in the 1980s longitudinal estimates from multiple panels for 1983 84 through 1989 90 suggest far smaller union premiums supporting the thesis that part of the wage differential following deregulation is a compensating premium for driver quality

exploring new ways of assessing the effect of regulation on environmental management abstract studies indicate that while a variety of factors positively influence voluntary environmental management regulatory pressures are among the most important however most research examines samples representing large manufacturers or single industries essentially assuming a level of regulatory constraint using a sample of heterogeneous facilities this study finds that facilities can be classified according to the level of regulatory constraint and that group membership impacts the choice of environmental management strategy when assessed within a utility maximization framework more extensively regulated facilities implement more individual environmental management practices but participate in fewer formal voluntary environmental programs veps compared to other facilities

labor supply of new york city cabdrivers one day at a time life cycle models of labor supply predict a positive relationship between hours supplied and transitory changes in wages because such changes have virtually no effect on life cycle wealth previous attempts to test this hypothesis empirically with time series data have not been supportive estimated elasticities are typically negative or nonsignificant such analyses however are vulnerable to measurement error and other estimation problems we use data on daily observations of wages and hours for new york city cab drivers to estimate the supply response to transitory fluctuations in wages cab drivers decide daily how many hours to supply and face wages that are positively correlated within days but largely uncorrelated between days using these data our central finding is that wage elasticities are persistently negative from 5 to 1 in three different samples even after correcting for measurement error using instrumental variables these negative wage elasticities challenge the notion that cab drivers trade off labor and leisure at different points in time and question the empirical adequacy of life cycle formulations of labor supply

environmental value chain in green sme networks the threat of the abilene paradox abstract demand side policies are an important complement to subsidies in fostering green product service markets green public procurement gpp in particular presents valuable characteristics in terms of directionality volumes and measurability despite being widely analysed from a public perspective gpp development is still under explored from a corporate point of view to shed some light on the strategic attitude of firms towards gpp this paper discusses an exploratory research in the field of road construction an inductive analysis of direct observations and theoretical contributions suggests the potential for the so called abilene paradox to hamper gpp opportunities for small and medium enterprises in fact in times of crisis increased pressures to improve performance and reduce risk resistance to change and strategic myopia can easily impair inter organizational interactions and thus prevent potentially innovative networks from pressuring public investments in green supply chains the related policy suggestions represent a first attempt to enter the realm of systemic approaches to gpp

technical change external economies and the porter hypothesis abstract michael porter introduces the idea that environmental regulations may benefit affected firms this paper derives results consistent with porter s hypothesis by employing a general equilibrium framework with a large number of agents external economies of scale in production and discrete changes in technology the model shows that endogenous technical change makes porter s hypothesis feasible however a policy that produces results consistent with porter s hypothesis is not necessarily optimal

a shred of credible evidence on the long run elasticity of labor supply all public policies regarding taxation and the redistribution of income rely on assumptions about the long run effect of wages rates on labour supply the variation in existing estimates calls for a simple natural experiment in which men can change their hours of work and in which wages have been exogenously and permanently changed we use a panel dataset of taxi drivers who choose their own hours and who experienced two exogenous permanent fare increases and estimate an elasticity of labour supply of 0 2 implying that income effects dominate substitution effects in the long run labour supply of males

environmental regulation technological innovation and energy consumption a cross region analysis in china abstract china has encountered the environmental issues and energy pressures in the middle income stage strengthening environmental regulation is a crucial measure to prevent environment deterioration and energy dilemma this paper investigates the three types of environmental regulations on energy consumption using feasible generalized least squares method during 1997 2015 in direct and indirect path the main conclusions are as follows in the direct path the economical and supervised types of environmental regulations have inhibited energy consumption whilst legal environmental regulation has no significant impact as for indirect path the rebound effect of energy is greater than the energy conservation generated by technological innovation which is embodied as an inhibitory effect the effects of environmental regulation display regional difference the legal and supervised types of environmental regulations have significant cost effect and rebound effect on energy consumption in the entire samples on the contrary the economical environmental regulation shows the opposite sigh in eastern regions the counterfactual simulation results show that the net effects of environmental regulations on energy consumption are negative which is beneficial for relieving energy pressures based on the findings this paper provides pertinent policy implications

governance pressures and performance outcomes of sustainable supply chain management an empirical analysis of uk manufacturing industry although sustainable supply chain management sscm has recently received increasing attention among uk manufacturing firms there is a concern as to whether sscm practices are being implemented because they are profitable or only because of governance coercive pressure thus the aims of this paper are twofold first determining the role of governance in the adoption of sscm practices second investigating whether sscm practices can be both environmentally beneficial and commercially viable in light of these issues this paper develops and empirically assesses an integrated model of governance pressures sscm practices performance data was collected from 146 uk manufacturing managers and analysed using the structural equation modelling method exogenous driving forces of governance were found to be precursors to the successful implementation of sscm practices the empirical results further suggest that while the implementation of sustainable supply chain management has a positive effect on environmental performance it does not necessarily lead to improved economic performance as only sustainable procurement was found to have a positive effect on economic performance this paper contributes to the literature by highlighting the role of governance in sscm adoption and performance gains in environmental protection while economic performance is partially compromised the results also provide useful insights for both managers seeking to adopt sustainable practices and policy makers seeking to further promote sustainable supply chain

environmental regulation and competitiveness empirical evidence on the porter hypothesis from european manufacturing sectors abstract this paper investigates the weak and strong versions of porter hypothesis ph focusing on the manufacturing sectors of 17 european countries between 1997 and 2009 the hypothesis that well crafted and well enforced regulation would benefit both the environment and the firm was originally proposed by porter 1991 and porter and van der linde 1995 to date the literature has analyzed the impact of environmental regulation on innovation and on productivity mostly in separate analyses and focusing on the usa the few existing contributions on europe study the effect of environmental regulation either on green innovation or on performance indicators such as exports we instead look at overall innovation and productivity impacts first focusing on overall innovative activity allows us to account for potential opportunity costs of induced innovations second productivity impacts are arguably the most relevant indicators for the strong ph as a proxy of environmental policy stringency we use pollution abatement and control expenditures pace one of the few sectoral level indicators available we remedy upon its main drawback namely potential endogeneity by adopting an instrumental variable estimation approach we find evidence of a positive impact of environmental regulation on the output of innovation activity as proxied by patents thus providing support in favor of the weak ph this result is in line with most of the literature on the other front we find no evidence in favor of the strong ph as productivity appears to be unaffected by the degree of pollution control and abatement efforts

social cost of environmental quality regulations a general equilibrium analysis the use of cost benefit analysis by federal regulatory agencies has expanded greatly in scope and sophistication unfortunately agencies continue to employ private cost rather than social cost to evaluate environmental quality regulations furthermore general equilibrium impacts and intertemporal effects of regulations are typically not included in the evaluation in this paper we estimate the social cost of environmental quality regulations mandated by the clean air and clean water acts we construct an econometric general equilibrium model of the united states to demonstrate that social cost estimates diverge sharply from private cost estimates we also demonstrate that general equilibrium impacts are significant and pervasive and that intertemporal effects of the regulations heretofore ignored are significant

disruptive change in the taxi business the case of uber in most cities the taxi industry is highly regulated and utilizes technology developed in the 1940s ride sharing services such as uber and lyft which use modern internet based mobile technology to connect passengers and drivers have begun to compete with traditional taxis this paper examines the efficiency of ride sharing services vis a vis taxis by comparing the capacity utilization rate of uberx drivers with that of traditional taxi drivers in five cities the capacity utilization rate is measured by the fraction of time a driver has a fare paying passenger in the car while he or she is working and by the share of total miles that drivers log in which a passenger is in their car the main conclusion is that in most cities with data available uberx drivers spend a significantly higher fraction of their time and drive a substantially higher share of miles with a passenger in their car than do taxi drivers four factors likely contribute to the higher capacity utilization rate of uberx drivers 1 uber s more efficient driver passenger matching technology 2 the larger scale of uber than taxi companies 3 inefficient taxi regulations and 4 uber s flexible labor supply model and surge pricing more closely match supply with demand throughout the day

industrial eco efficiency in china a provincial quantification using three stage data envelopment analysis abstract the coordinated development of industrialization and the ecological environment is vital to achieve ecological civilization in china integratively considering the economy energy and resources and environment this study aims to measure the industrial eco efficiency of 30 provinces autonomous regions and municipalities in china between 2005 and 2013 a three stage data envelopment analysis dea modeling approach is adopted to eliminate interference of the external environment and statistical noise with industrial eco efficiency measurement the results show that regional industrial eco efficiency in china is affected by the factors of the environmental regulation technological innovation level of economic development and industrial structure after eliminating the impacts of external environment and statistical noise china s national average industrial eco efficiency declines by 30 between 2005 and 2013 the industrial eco efficiency of the 30 provinces increases but at different rates of growth the variation of overall regional industrial eco efficiency is primarily caused by scale efficiency furthermore all the 30 provinces are classified into four groups to interpret the causes of variation and differences of regional industrial eco efficiency in general the management and technology level and the economy of scale of industries should be improved simultaneously even though specific opportunities for industrial eco efficiency improvement vary across provinces in china

data envelopment analysis for environmental assessment comparison between public and private ownership in petroleum industry abstract environmental assessment recently becomes a major policy issue in the world this study discusses how to apply data envelopment analysis dea for environmental assessment an important feature of the dea environmental assessment is that it needs to classify outputs into desirable good and undesirable bad outputs because private and public entities often produce not only desirable outputs but also undesirable outputs as a result of their production activities this study proposes the three types of unification for dea environmental assessment by using non radial dea models the first unification considers both an increase and a decrease in the input vector along with a decrease in the direction vector of undesirable outputs this type of unification measures unified efficiency the second unification considers a decrease in an input vector along with a decrease in the vector of undesirable outputs this type of unification is referred to as natural disposability and measures unified efficiency under natural disposability the third unification considers an increase in an input vector but a decrease in the vector of undesirable outputs this type of unification is referred to as managerial disposability and measures unified efficiency under managerial disposability all the unifications increase the vector of desirable outputs to document their practical implications this study has applied the proposed approach to compare the performance of national oil firms with that of international oil firms this study identifies two important findings on the petroleum industry one of the two findings is that national oil companies under public ownership outperform international oil companies under private ownership in terms of unified operational and environmental efficiency and unified efficiency under natural disposability however the performance of international oil companies exhibits an increasing trend in unified efficiency the other finding is that national oil companies need to satisfy the environmental standard of its own country while international oil companies need to satisfy the international standard that is more restricted than the national standards as a consequence international oil companies outperform national oil companies in terms of unified efficiency under managerial disposability

economic convergence and climate policy abstract this paper addresses the relevance of the economic convergence hypotheses between the developing and the developed world in international greenhouse gas ghg emissions negotiations the results are based on a two region the oecd and the rest of the world row neo classical growth model with exogenous technical progress different technological diffusion patterns and a set of geophysical relationships that consider an environmental externality linked to ghg emissions a game framework is taken into account in the model to capture the strategic interactions between agents the outcome of the negotiations seems indeed to depend on the economic convergence hypotheses faster economic growth of the row countries would encourage them to further mitigate carbon emissions

assessing whether corporate social responsibility influence corporate value abstractthis study used the corporate social responsibility csr index to gauge the corporate value and social responsibility performance of corporations in taiwan we investigated whether csr influences corporate value and whether the extent of that influence varies with corporate value or time the results indicate that the influence of csr on corporate value does not change with time csr exerts a positive influence on company value and this influence does not change over time however the extent of the influence significantly varies with corporate value when the corporate value of a company is not high investing in csr would only increase costs and fail to effectively increase corporate value in contrast if the corporate value of the company is high investments in csr in this circumstance would instead promote the effective increase of corporate value

environmental innovations and profitability how does it pay to be green an empirical analysis on the german innovation survey much of the empirical literature analysing the relation between environmental innovation and competitiveness has focused on the question whether it pays to be green we differentiate between different types of environmental innovations which will be disentangled in those aiming at reducing the negative externalities and those allowing for efficiency increases and cost savings what we analyze is at first the extent to which these two typologies have impacts on firms profitability with opposite signs and secondly whether the motivations driving the adoption of those innovations make the difference in terms of economic gains we find empirical evidence that both the typology of environmental innovation and the driver of their adoption affect the sign of the relationship between competitiveness and environmental performance the empirical strategy is based on a sample of german firms and makes use of a merge of two waves of the mannheim innovation panel in 2011 and 2009 that allow overcoming some endogeneity issues which may arise in a cross section setting

environmental policy and the equilibrium rate of unemployment abstract this paper integrates environmental policy instruments with the theory of equilibrium unemployment we investigate the question of whether a low equilibrium rate of unemployment and a high quality of the environment are complementary policy goals or must be traded off it turns out that an interval exists for a tax on emissions where the two goals are indeed complementary the tax stimulates the emergence of an abatement sector which provides pollution control and vacancies for the job seekers for constrained efficiency the policy maker operates five instruments to internalize the environmental and the search externalities a tax on emissions employment subsidies and recruiting allowances for the polluting industries are sufficient to implement the first best the optimal emission tax is an increasing function of the workers bargaining strength for labor markets where workers have a strong bargaining position the optimal pollution tax may easily exceed the pigouvian tax

are long term wage elasticities of labor supply more negative than short term ones standard models imply that the wage elasticity of labor supply is more negative the longer a wage change lasts i observe decreasing daily hours during short term wage increases but not during a long term one daily income goals adjusted in the long term

environmental regulation a value theoretic and class based analysis following a value theoretic and class based approach it is argued in this paper that ecological problems are inseparably linked to the process of extracting surplus value in capitalism and owing to their adverse impacts instigate struggles over the appropriation of nature these struggles fought within and outside the state by competing agents shape environmental regulation in particular taxes permits command and control measures and subsidies affect prices profits and rents and have class and other social implications evidence of current environmental regulation shows that it takes places under the great influence of capitalist concerns

when green isn t mean economic theory and the heuristics of the impact of environmental regulations on competitiveness and opportunity cost abstract the conventional neoclassical economic wisdom argues that the opportunity costs of environmental regulations are high with negative implications for costs and profits and by implication for growth and per capita gross domestic product gdp the minority view that environmental controls induce cost offsets that minimise such opportunity costs is marginalised by the conventional wisdom which assumes that economic agents are x efficient in production a behavioral model of the firm is presented in this paper whereby x inefficiency in production prevails even in a world of perfect product market competition that is dominated by rational economic agents in this model environmental regulations affect both the level of x efficiency and the extent of technological change and greener firms can be cost competitive and profitable however private economic agents cannot be expected to adopt green economic policy independent of regulations since in this model there need not be any economic advantage accruing to the affected firms in becoming greener

public preferences for carbon tax attributes the impacts of climate change are already visible throughout the world recognizing the threats posed by climate change the durban platform the 17th session of the conference of parties cop 17 underscores that the global nature of climate change calls for the widest possible cooperation and ambitious action by all countries a crucial starting point for the design of effective and publicly acceptable policies is to explore public preferences for climate policy instruments using a choice experiment this study investigates public preferences for carbon tax attributes in a developing country context the results account for heterogeneity in preferences and show that turkish people prefer a carbon tax with a progressive cost distribution rather than one with a regressive cost distribution the private cost has a negative effect on the probability of choosing the tax earmarking carbon tax revenues increases the public acceptability of the tax moreover there is a preference for a carbon tax that promotes public awareness of climate change

reviewing the business case for corporate social responsibility new evidence and analysis this study complements previous empirical research on the business case for corporate social responsibility csr by employing hitherto unused data on corporate social performance csp and proposing statistical analyses to account for bi directional causality between social and financial performance by allowing for differences in the importance of single components of csp between industries the data in this study overcome certain limitations of the databases used in earlier studies the econometrics employed offer a rigorous way of addressing the problem of endogeneity due to simultaneous causality although the study s results provide no evidence that there is a generic or universal business case for csr they indicate that there is a strong link between single stakeholder related issues of csr and financial performance however the analysis does not establish causality within these relationships

the impact of green innovation on energy intensity an empirical analysis for 14 industrial sectors in oecd countries abstract this paper analyses the impact of green innovation on energy intensity in a set of 14 industrial sectors in 17 oecd countries over the 1975 2005 period we create a stock of green patents for each industrial sector and estimate a translog cost function to measure the impact of green innovation on energy intensity next to other factors such as input substitution and autonomous technical change we find that green innovation has contributed to the decline in energy intensity in the majority of sectors the median elasticity of energy intensity with respect to green patenting is estimated at 0 03 in our sample hence a 1 increase in green patenting activities in a given sector is associated with a 0 03 decline in energy intensity the magnitude of the effect is robust across various specifications and is larger in more recent years a decomposition exercise shows that overall half of the decrease in energy intensity over the sample period is related to changes in input prices and half to changes in production technologies

strategic policy and environmental quality helping the domestic industry to provide credible information this paper shows that a country can improve an industry s competitiveness by requiring domestic firms to produce at the environmental standards at which they claim to produce or otherwise impose a penalty on those firms found cheating competitiveness will improve because this regulation will help the domestic industry to provide credible information about the environmental quality of its production the credible information will differentiate domestic products from other products on the world market and in this way increase consumers willingness to pay for domestic products even if the government has no preferences for environmental quality it has incentives to regulate its cheaters in order to help the domestic industry to provide credible information and thereby improve competitiveness

game theoretic models for climate change negotiations abstract negotiations to reduce greenhouse gas accumulation in the atmosphere are modeled as extensive games of perfect information various solution concepts such as nash equilibrium reaction function equilibrium correlated equilibrium and bargaining solutions are applied analyzed and computed special reduction techniques are used when the size of the game tree becomes excessive a new solution concept the tree correlated equilibrium is also introduced main features of an excel add in designed to compute various solutions are briefly described and a sample policy analysis for a special negotiating scenario is discussed

international technology oriented agreements to address climate change much discussion has surrounded possible alternatives for international agreements on climate change particularly post 2012 among these alternatives technology oriented agreements toas are perhaps the least well defined we explore what toas may consist of why they might be sensible which toas already exist in international energy and environmental governance and whether they could make a valuable contribution to addressing climate change we find that toas aimed at knowledge sharing and coordination research development or demonstration could increase the overall efficiency and effectiveness of international climate cooperation but are likely to have limited environmental effectiveness on their own technology transfer agreements are likely to have similar properties unless the level of resources expended is large in which case they could be environmentally significant technology specific mandates or incentives could be environmentally effective within the applicable sector but are more likely to make a cost effective contribution when viewed as a complement to rather than a substitute for flexible emissions based policies these results indicate that toas could potentially provide a valuable contribution to the global response to climate change the success of specific toas will depend on their design implementation and the role they are expected to play relative to other components of the policy portfolio

empirics on the long run effects of building energy codes in the housing market we study the effectiveness of building energy codes taking a long run perspective the focus is on regulation s impact on energy demand in both high and low quality residences in other words the diffusion and the entry of green buildings in the housing market we develop a measure for regulation intensity and apply this to a panel error correction regression model for energy requirements of a large sample of german apartment houses built between 1950 and 2005 we show that regulation is effective in saving energy in particular regulation pushes investors in the low quality housing market segment toward the technological frontier indirectly it also affects the high quality segment jel q41 r52
