environmental regulation industrial innovation and green development of chinese manufacturing based on an extended cdm model abstract as for the academics and policymakers more attention has been given to the issue on how to drive green development of the manufacturing through regulations and innovations we construct the extended crepon duguet mairesse cdm model and employ the panel data of chinese manufacturing industries during 2003 2014 to examine the effects of environmental regulation on industrial innovation and green development the findings reveal that 1 in the long term environmental regulation has crowded out r d investment 2 environmental regulation has inhibited patent outputs so that the weak version of porter hypothesis is not underpinned 3 in the short term environmental regulation has promoted the improvements of labor productivity energy efficiency and environmental efficiency in the manufacturing industry excluding green total factor productivity gtfp whereas in the long term environmental regulation only has increased energy efficiency while it has obstructed labor productivity which provides no support for the strong version of porter hypothesis 4 different innovation outputs have distinct influences on labor productivity energy efficiency environmental efficiency and gtfp finally this paper provides pertinent policy implications

stock returns before and after calls of convertible bonds ofer and natarajan 1987 report negative statistically significant cumulative average abnormal returns over five years following convertible bond calls we show that these results are obtained only if returns preceding the call dates are used for market model parameter estimation returns preceding calls tend to be positive and unusually large this means that predicted post call returns based on pre call parameter estimates are biased upward consequently the corresponding abnormal returns are biased downward we also discuss a corrected test statistic we conclude that the evidence does not indicate market inefficiency in the stock price reaction to convertible calls

does environmental policy stringency foster innovation and productivity in oecd countries abstract in this paper we test the weak and strong versions of the porter hypothesis using data from 14 oecd countries over the period 1990 2011 our analysis makes two contributions to the literature on the topic first we use a newly released environmental policy stringency index eps provided by the oecd as an indicator for the stringency of environmental regulations which addresses the multi dimensionality of environmental regulations second as a suitable method to deal with asymmetric distributions of the dependent variables we use a panel quantile regression model which allow us to test whether or not the hypothesis holds for all quantiles of the distribution of the corresponding dependent variable the findings indicate that in the short term a more strict environmental policy is associated with an increase in the number of patent applications and in total factor productivity tfp for the highest quantiles of the distribution of patents and for all quantiles of tfp respectively moreover environmental stringency has a positive effect on research and development expenditures rd only in the lower quantiles 10 25 in the long term the eps is affecting rd patents and tfp in all quantiles and hence more stringent environmental regulations promote cleaner production processes that could help improving energy efficiency

ownership and environmental regulation evidence from the european electricity industry abstract the paper investigates how ownership affects the environmental performance in developed countries where environmental regulation is introduced in the form of market based instrument by looking at a cross country panel dataset of 29 power markets around europe over the period 1990 2012 we find empirical evidence that an increase of public ownership as measured by the oecd etcr index is associated with a reduction of both greenhouse gas emissions and carbon intensity we also find that the implementation of the european emissions trading scheme ets had a limited impact on emissions reduction due to lax allocation of allowances the positive effect of public ownership on environmental performance has been significant even after the introduction of the ets giving additional incentives to mitigate emissions when the ets cap was not stringent enough this evidence suggests that government control over power companies in europe can has created idiosyncratic incentives to improve environmental quality complementing environmental regulation in the achievement of environmental goals when the latter was absent or sub optimal

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

the strategic interaction between firms and formulary committees effects on the prices of new drugs we study the strategic interaction between the pricing decisions of a pharmaceutical firm and the reimbursement decisions of a government agency which grants reimbursement rights to patients for whom new drugs are most cost effective if the reimbursement decision precedes pricing the agency only reimburses some patients if the drug s private and public health benefits diverge this is there are consumption externalities and the variable cost of the drug exceeds the alternative s contrarily if the firm can commit to a price before reimbursement a strategic effect implies that by setting a sufficiently high price the firm can make the agency more willing to reimburse than without commitment

plant vintage technology and environmental regulation abstract we use data on productivity and pollution abatement costs at individual pulp and paper mills to test whether the impact of environmental regulation on productivity differs by plant vintage and technology plants with higher pollution abatement costs have significantly lower productivity levels this relationship differs greatly based on a plant s technology with productivity at integrated mills being greatly affected by abatement costs while the impact at non integrated mills is negligible plant vintage does not seem to matter with older and newer plants showing similar impacts reported abatement costs appear to substantially understate the true costs of abatement accounting for the impact of technology differences makes some difference in the estimated overall impact of environmental regulation

monopoly pricing with negative network effects the case of vaccines abstract we study the market for vaccinations considering income heterogeneity on the demand side and monopoly power on the supply side a monopolist has an incentive to exploit the external effect of vaccinations and leave the poor susceptible in order to increase the willingness to pay the rich even the possibility of price discrimination does not remove this incentive we demonstrate that the weaknesses of standard policy measures are mitigated when income heterogeneity is taken into account this offers an efficiency based rationale for distribution oriented national or international public health interventions

attitudes towards climate policies in a macrodynamic model of the economy abstract in a recent article published in this journal guarini and porcile 2016 expanded the balance of payments constraint bopc growth model suggesting a way to make it possible to address some of the challenges posed by greenhouse gas emissions building on their set up we formalise into the model a mechanism that explains how people with different environmental attitudes or sentiments influence each other and contribute to the design of environmental policies we detail the concept of transition probabilities for the agent s switching from pro to anti environmental positions and vice versa and discuss the macroeconomic results that follow numerical simulations allow us to investigate in more detail the implications of the validity of porter s hypothesis as well as to discuss the feasibility of decoupling conditions a policy implication of our analysis is that we should encourage the dissemination of pro environmental attitudes among the public because this could lead to a more desirable equilibrium as important as enhancing public knowledge of climate change is to keep alive the debate at the collective level so as to influence the probability of switching sides

the two faces of competition dynamic resourcefulness and the hypercompetitive shift competition in the american economy has fundamentally changed over the last few decades from static to dynamic this study labels this important change the hypercompetitive shift and documents it across 200 industries of the us manufacturing sector during i958 to 1991 for industries that undergo a hypercompetitive shift there is an increase in the cross firm variance in performance and a rotation in the value rivalry relationship from a negative association to an inverted u as a consequence of these competitive changes the strategic focus of firms shifts from careful exploitation of given highly durable strategic assets to the steady creation of many new rapidly depreciable ones the key driver of hypercompetitive shift is the dynamic resourcefulness of an industry or the ease with which new strategic assets can be created determinants of dynamic resourcefulness include the dynamism of related transactors notably consumers and suppliers the knowledge base of the industry and structural condi

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

is environmental policy a secondary trade barrier an empirical analysis should international trade agreements be extended to include negotiations over environmental policy the answer depends on whether countries distort levels of environmental regulations as a secondary means of providing protection to domestic industries our results suggest that they do previous studies of this relationship have treated the level of environmental regulation as exogenous and found a negligible correlation between environmental regulation and trade flows in contrast we find that when the level of environmental regulation is modelled as an endogenous variable its estimated effect on trade flows is significantly higher than previously reported jel classification fl f14 f18 est ce que la politique environnementale est une barriere commerciale secondaire une analyse empirique est ce que les accords commerciaux internationaux doivent etre etendus pour couvrir la politique environnementale la reponse depend du degre de distorsion que les pays introduisent dans leur politique environnementale pour proteger leurs industries nationales nos resultats suggerent que cet impact est important des etudes anterieures de cette relation ont traite la politique environnementale comme exogene et ont montre qu il existe une co relation negligeable entre politique envir onnementale et flux commerciaux au contraire nous revelons que quand la politique environnementale est consideree comme variable endoge ne son effet sur les flux com merciaux est plus eleve de maniere significative que ce qu on a note anterieurement

interaction protection and epidemics abstract individuals respond to the risk of contagious infections by restricting interaction and by investing in protection we develop a model that examines the trade off between these two actions and the consequences for infection rates there exists a unique equilibrium individuals who invest in protection choose to interact more relative to those who do not invest in protection changes in the contagiousness of the disease have non monotonic effects as a result interaction initially falls and then rises while infection rates too may initial increase and then decline we then consider a society with two communities that differ in their returns from interaction high and low individuals in isolated communities exhibit different behavior the high community has a higher rate of protection and interaction and a lower rate of infection integration amplifies these differences

the control of invasive species on private property with neighbor to neighbor spillovers invasive pests cross property boundaries property managers may have private incentives to control invasive species despite not having sufficient incentive to fully internalize the external costs of their role in spreading the invasion each property manager has a right to future use of his own property but his property may abut others properties enabling spread of an invasive species the incentives for a foresighted property manager to control invasive species have received little attention we consider the efforts of a foresighted property manager who has rights to future use of a property and has the ability to engage in repeated discrete control activities we find that higher rates of dispersal associated with proximity to neighboring properties reduce the private incentives for control controlling species at one location provides incentives to control at a neighboring location control at neighboring locations are strategic complements and coupled with spatial heterogeneity lead to a weaker link public good problem in which each property owner is unable to fully appropriate the benefits of his own control activity future use rights and private costs suggest that there is scope for a series of coase like exchanges to internalize much of the costs associated with species invasion pigouvian taxes on invasive species potentially have qualitatively perverse behavioral effects a tax with a strong income effect e g failure of effective revenue recycling can reduce the value of property assets and diminish the incentive to manage insects on one s own property

does china s carbon emission trading policy have an employment double dividend and a porter effect abstract the implementation of china s carbon emission trading policy has targeted achieving emission reduction and environmental protection as well as promoting economic development and technological innovation the analysis is made through applying the difference in differences model and using the ordinary least squares method and the least square dummy variable method in the paper results show that the pilot carbon emission trading policy leads to the expansion of employment scales and the reduction of carbon emissions after controlling for the environmental regulation population size economic level and other important variables thus it implies that an employment double dividend exists for the porter effect it is found in the pilot carbon emission trading policy only without adding any control variable the effect is further verified based on a robustness checks and a placebo test furthermore from the perspective of market oriented environmental regulation policy this study explains that the carbon emission trading system launched in 2017 needs to be improved to spread both the employment double dividend and the porter effect to the whole nation china also needs to form a complete set of strict ecological environment protection policies and administrative measures to achieve sustainable development of the economy

schumpeterian competition in experimental markets abstract we report on a series of laboratory experiments that capture key elements of research and development r d rivalry the experimental environment has a small number of sellers who compete in terms of pricing and production decisions and in terms of cost reducing r d rewards for innovation depend on the profitability of product market competition the experiments capture a kind of dynamic schumpeterian competition there is a sharp contrast in experimental results between monopolies and four seller competitive markets aggregate r d is higher under competition than under monopoly and prices follow marginal cost reductions much more quickly under competition than under monopoly the paper examines market performance in the experiments and the sources of market performance problems

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

the effects of environmental regulation on china s total factor productivity an empirical study of carbon intensive industries abstract in this paper we first identify china s carbon intensive industries ciis by constructing a carbon intensive index taking both the scale and intensity of co2 emission into account then the strong version of porter hypothesis ph i e the positive effect of environmental regulation on total factor productivity tfp of china s ciis is tested in order to overcome the endogenous issue of model specification two stage least squares 2sls method is employed the results indicate that there is a significant inverted u shape relationship between environmental regulation intensity and the tfp of china s ciis demonstrating the inexistence of strong ph effect in a long run and the impact of environmental regulation on ciis is changing gradually from innovation offsets to compliance costs in addition optimal environmental regulation intensities for different ciis are also studied according to their locations on the inverted u shaped curve the production and supply of electric power and heat power industry has exceeded the optimal environmental regulation intensity while the remaining ciis have not reached their inflection points therefore specific policy proposals should be formulated according to the different stages of environmental regulation in various industries

structural innovation and efficiency effects of environmental regulation evidence from china s carbon emissions trading pilot conventional wisdom argues that environmental regulation can trigger both structural adjustments and enhanced innovation we test this conjecture by using a difference in differences approach to analyze the impacts of china s carbon emission trading cet pilot policy on energy consumption we find that compliance with the cet regulation has triggered statistically significant adjustments in energy structure industrial structure and technological innovation adjustments in industrial structure also contribute to enhanced total factor energy efficiency whereas increased technological innovation has mixed effects on energy efficiency we show that in the short run government led innovation does not immediately contribute to improvement in energy efficiency whereas enterprise led innovation has a negative impact it indicates that cet regulation can affect energy efficiency through industrial structure and technological innovation overall our results provide new evidence for the strong version of the porter hypothesis our results also provide strong scientific support for china s recent transition towards market based carbon mitigation strategies

environmental innovation and environmental performance abstract by estimating a simultaneous panel data model of environmental innovation and toxic air pollution this paper identifies bi directional causal links between the two we study a panel of 127 manufacturing industries over the period 1989 2004 pollutant emissions are an implicit measure of policy stringency and environmental patent counts are used to measure environmental innovation after accounting for the joint endogeneity we find that environmental innovation is an important driver of reductions in us toxic emissions conversely we find that tightened pollution targets induce environmental innovation however our estimates indicate that the environmental policy multiplier the proportionate contribution of induced innovation to long run emission reduction is small

non adherence to a low fat diet an economic perspective abstract despite bearing increased risk of suffering a heart attack failure to adhere to a low fat dietary regimen is wide spread the paper applies an expected utility maximization model to inquire into the individual s decision to deviate from a prescribed low fat diet offering an economic explanation for excess high fat consumption the implications of self protection against the risk of dying from an attack are further examined the analysis reveals that self protection and dietary adherence can be complements suggesting that public health policy may help reduce both the risk of an attack and the risk of dying from an attack through providing incentives for self protection

optimal tax subsidy combinations for the flu season this paper uses a dynamic susceptible infected recovered sir epidemic model to identify optimal vaccination policy mixes for the flu season it begins with the solution to the relevant optimal control problem and then gives the derivation of a perfect foresight equilibrium outcome for vaccination behavior in an unregulated market both the optimal and market outcomes are characterized by switching curves in s i state space exact expressions for these are derived the final section discusses taxes and subsidies that can be used to attain the optimal outcome

liquidity costs and stock price response to convertible security calls firms announcements to call in the money convertible securities for redemption essentially force their conversion into common stock and such announcements are generally met with significant reductions in the calling firms equity values an explanation based on liquidity costs is advanced and tested the explanation implies that investors who choose to sell their shares early in the conversion period bear liquidity costs by selling at reduced prices consistent with the explanation the average share price decline is short lived lasting most of the conversion period thus a component of the call announcement effect appears to be due to liquidity costs copyright 1992 by university of chicago press

r d appropriability opportunity and market structure new evidence on some schumpeterian hypotheses one of the largest bodies of literature in the field of industrial organization is devoted to the interpretation and testing of several hypotheses advanced by joseph schumpeter 1950 concerning innovation and industrial market structure one set of hypotheses focuses on the role of firm size as a determinant of r d spending and the rate of technological advance another set focuses on the effect of market concentration on r d and technological advance in this paper we reexamine the latter set of hypotheses at the industry level using new data on r d appropriability and technological opportunity collected by levin et al 1984 in a survey of r d executives in 130 industries

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

stock reaction to dividend savings of convertible preferred calls free cash flow or price pressure effects abstract calls of in the money convertible preferred stock typically induce dividend savings for the firm since preferred dividends exceed common stock dividends prior research finds that these savings are negatively related to stock returns at call announcement and argues that the market expects managers to abuse the increased free cash flow this paper finds that dividend savings are closely related to call size suggesting other explanations larger calls experience a more negative announcement reaction consistent with temporary liquidity effects there is a price reversal during the conversion period which is greater for larger calls

economic growth energy prices and technological innovation energy economists are repeatedly asked to analyze the short run and long run macroeconomic effects of energy price shocks the authors examine the effect of energy prices in a dynamic model of economic growth as a function of capital labor energy prices and technological innovation their approach extends earlier studies in two ways first they depart from the standard approach of modeling strictly in either levels or differences by using an error correction model the advantage of this approach is that both short run and long run information is used in the model second they construct a measure of technological innovation with patent filings typically deterministic trends have been used to capture technological growth the increase in energy efficiency since 1974 had been due to energy conservation and improvements in energy intensive capital stock and production processes they authors try to simultaneously use energy prices and technological innovation in a model of macroeconomic growth if energy price symmetry is imposed they conclude that the short run energy price effects are approximately half the long run energy price effects when the restriction is relaxed short run price symmetry does not hold in particular short run price increases are associated with economicmore downturns while short run price declines have no significant impact on economic activity also the results show that technological innovation measured through the stock of patents contributes both directly to economic growth and indirectly through improvements in the economy s capital stock less

market structure and communicable diseases communicable diseases pose a formidable challenge for public policy using numerical simulations we show under which scenarios a monopolist s price and prevalence paths converge to a non zero steady state in contrast a planner typically eradicates the disease if eradication is impossible the planner subsidizes treatments as long as the prevalence can be controlled drug resistance exacerbates the welfare difference between monopoly and first best outcomes nevertheless because the negative externalities from resistance compete with the positive externalities of treatment a mixed competition monopoly regime may perform better than competition alone this result has important implications for the design of many drug patents les maladies contagieuses posent un defi important a la politique publique a l aide de simulations numeriques on montre dans quels scenarios les prix de monopole et le sentier de prevalence tendent a engendrer un regime permanent ou la maladie ne disparait pas un planificateur typiquement elimine la maladie si l eradication est impossible le planificateur subventionne les traitements aussi longtemps que la prevalence peut etre controlee la resistance au remede agrandit l ecart de bien etre entre le cas du monopole et l optimum cependant comme les effets externes negatifs de la resistance au traitement sont en conflit avec les effets externes positifs des traitements un regime mixte concurrence monopole peut donner de meilleurs resultats que la seule concurrence ce resultat a des implications importantes pour l elaboration de nombreux brevets pharmaceutiques

tax shields sample selection bias and the information content of conversion forcing bond calls the information content of conversion forcing bond calls depends on the after tax cash flow to bondholders if the dividend after conversion exceeds the after tax coupon but is less than the before tax coupon the call reveals unanticipated decreases in dividends and or earnings that reduce the tax shield from interest payments in contrast a call when the dividend is less than the after tax coupon reveals the timing of an anticipated shift from exceptional firm specific positive growth to the industry norm efforts to document properties of convertible calls are subject to sample selection bias because calls are disproportionately associated with positive pre call firm specific growth brennan and schwartz 1977 1980 and ingersoll 1977a show that if capital markets are perfect the optimal policy is to call and force conversion the first time the bond s conversion value exceeds its cash redemption value however ingersoll 1977b 1 and constantinides and grundy 1987 provide evidence that firms delay calling convertible debt and mikkelson 1980 1981 ofer and natarajan 1987 and singh cowan and nayar 1990 document a statistically significant negative return to equity at the call announcement to explain these results which are inconsistent with the optimal call policy and its predicted effect on equity value in a perfect capital market several asymmetric information hypotheses have been put forth mikkelson 1981 1985 hypothesizes that the negative market reaction results from the market inferring that management expects a decline in the present value of the debt s tax shield possibly due to a decline in future earnings this suggests that managers refrain from calling due to the tax shields provided by the debt harris and raviv 1985 present a signaling model in which a

public control of rational and unpredictable epidemics abstract efforts to improve disease forecasting are often justified on the grounds that accurate and reliable forecasts offer opportunities to improve response to epidemics yet little is known about how disease forecasts influence the responsiveness to public health interventions this paper couples an optimal stopping model and rational disease prevention with a stochastic compartmental epidemiological model of disease spread to develop a framework for evaluating the timing of public health interventions in response to rational but unpredictable epidemics optimal behavior by a public health agency is characterized by a pair of critical prevalence thresholds that trigger implementation and suspension of a public prevention program unlike existing economic thresholds for disease prevention our decision thresholds account for time varying probabilities of different levels of infection prevention by private individuals and the likelihood of crossing epidemiological thresholds that determine disease persistence

determinants of innovation the study examines how firm size market structure profitability and growth influence innovative activity in small to medium sized australian manufacturing businesses using the recently released confidentialised unit record file drawn from the business longitudinal survey of the australian bureau of statistics regression analysis is conducted to determine the factors that effect subsequent innovative activity for the full sample of businesses as well as for sub samples of firms from high and low technological opportunity industries most variables including size r d intensity market structure and trade shares are found to be conducive to further innovative activity for the full sample and for high tech firms for low tech industries fewer variables are significant

is a convertible bond call really bad news we test and reject the hypothesis that managers call in the money convertibles when they view a decline in the value of the firm as likely inconsistent with this view we find that insiders generally buy equity before conversion forcing calls also analysts tend to raise their earnings forecasts following a call thus our evidence supports the alternative hypothesis that the price decline immediately following conversion forcing calls is a purely transitory decline caused by the anticipated increase in the supply of equity indeed our evidence confirms that the initial price decline is reversed in the weeks following the announcement

environmental regulation and green productivity growth empirical evidence on the porter hypothesis from oecd industrial sectors abstract green growth has become an important development strategy for oecd countries and governments have correspondingly implemented various environmental regulation policies whereas few studies have discussed the impacts of environmental regulation on green productivity growth in oecd countries based on a panel data of oecd countries industrial sectors this study analyzes the stringency of environmental regulation policies and measures green productivity growth using an extended sbm ddf approach the dynamic panel regression investigates the impacts and mechanism of environmental policy stringency on green productivity growth in oecd countries industrial sectors the main results are i porter hypothesis is validated that the environmental policy has a positive impact on green productivity growth within a certain level of stringency lower than 3 08 ii the impact turns to be adverse when the environmental regulation policy is stringent over a certain level as the compliance cost effect is higher than innovation offset effect the findings provide new empirical evidence for the strong version of the porter hypothesis and some implications for oecd countries to further promote green growth

productivity growth and environmental regulation in mexican and u s food manufacturing many argued during the nafta debate that trade liberalization would favor mexican over u s food processors especially because of lax environmental laws south of the border we find through an examination of profit functions that productivity growth in mexico has outstripped that in the united states suggesting free trade indeed will benefit mexican suppliers u s pollution regulations have had no impact on the profitability or productivity of u s food manufacturing in contrast mexico s swiftly rising environmental standards have enhanced food processors productivity growth corroborating the porter hypothesis pollution law therefore has favored mexican over u s food processing but for reasons few had anticipated

global disease eradication an infectious disease can only be eradicated globally if it is eliminated in every country but does this require only international coordination or does it require cooperation using a model that blends epidemiology economics and game theory this paper shows that coordination will not always suffice even when the global benefits of eradication exceed the costs in general eradication will require strong international institutions jel h41 i18 k33 o19

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

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

tax subsidy policies toward vector borne infectious diseases abstract vector borne diseases especially rife in poor countries pose sectoral tax subsidy issues preventions and therapies mitigate these diseases in a numerical optimization model combining dynamic epidemiology and economics the medical distinction between prevention and therapy does not distinguish economic properties of preventions and therapies some interventions increase and others decrease moving to the steady state depending on the utility function the targeting of interventions and the disease process interventions display negative own price but indeterminate cross price effects juxtaposing the social planner s with decentralized choices quantifies externalities and shows how subsidies implement the first best one prevention and the therapy are equally subsidized

the microeconomics of market making this paper examines the influence of risk aversion on the pricing policies of a market maker for securities it is shown that a market maker s bid ask spread can be decomposed into a portion for the known limit orders a risk neutral adjustment for expected market orders and a risk adjustment for market order and inventory value uncertainty it is dem onstrated that a risk averse market maker may set a smaller spread than a risk neutral specialist finally this paper demonstrates the pervasive role of inventory in affecting both the placement and size ofthe spread

how do environmental regulation and environmental decentralization affect green total factor energy efficiency evidence from china abstract green development is critical for china s economic transformation enhancing green total factor energy efficiency hereafter gtfee is vital to emission reduction and to win win industrial development this study uses the panel data of 30 chinese provinces for the period 2005 2016 to investigate the relationship between environmental regulation and china s gtfee the spatial durbin model is employed to control for the possible spatial spillover effect a dynamic threshold panel model that can effectively address the endogeneity problem and regional heterogeneity is utilized to examine the potential non linear relationship between environmental regulation and gtfee under different conditions of environmental decentralization the estimation results indicate that there is a significant u shaped relationship between environmental regulation and china s gtfee with the further expansion of environmental decentralization the local government s autonomous choice of pollution control is improved the improvement of environmental decentralization can lead to negative moderating effect of environmental regulation on gtfee additionally the regression results of dynamic threshold model show that environmental decentralization can increase the negative influences of environmental regulation on gtfee interestingly the non linear impact of environmental regulation on gtfee is dependent on the specific type of environmental decentralization higher degree of environmental decentralization can lead to an increase in the restraining effect of environmental regulation on gtfee however an improvement in the decentralization of environmental supervision and environmental monitoring can increase the negative influences of environmental regulation on gtfee

challenges for r d and innovation in energy abstract in recent years there has been a growing interest in the role of r d and innovation in energy efficiency and dealing with climate change to improve our knowledge in these matters a workshop was organized in barcelona spain in january 2014 this introduction to the special issue first presents some insights from the literature on challenges for r d and innovation in energy the second section summarises the articles from this workshop that make up this special issue and that provide new insights into innovation in energy all the articles include energy policy recommendations based on the empirical analyses carried out

the effect of within sector upstream and downstream energy taxes on innovation and productivity the aim of this paper is to investigate the effect of environmental regulatory stringency on innovation and productivity using a panel of 8 european countries for 13 manufacturing sectors over the years 2001 2007 this research topic falls under the heading of the porter hypothesis ph of which different versions have been tested we consider both the strong and the weak versions of the ph while also adding some peculiar features to the analysis firstly we assess the role played by environmental taxes that is an instrument rarely tested as a factor which can support the ph secondly we analyse not only the effect of environmental taxes within a given sector within sector but also the role played by environmental taxes in upstream and downstream sectors in terms of input output relationships thirdly we test these relationships also indirectly by verifying whether innovation is one of the channels through which higher sectoral productivity can be achieved by imposing tighter environmental regulations our main findings suggest that downstream stringency is the most relevant driver of innovation and productivity while within sector regulations only affect productivity but not innovation moreover the effect of regulations on productivity is mostly direct while the part of the effect mediated by induced innovations as measured by patents is relevant only for what concerns downstream regulations

equilibrium vaccination patterns in incomplete and heterogeneous networks abstract under vaccination is a usual concern of disease control studies but this paper employs a simultaneous move game in a three agent contagion network to show that it is only one of the three inefficient patterns when the network structure is incomplete or individual characteristics are heterogeneous there exist new types of nash equilibrium outcomes with either the right number but wrong set of people getting vaccinated or too many vaccinations and these equilibria are robust to standard refinements while untargeted policies can correct the standard under vaccination problem targeted policies are more palatable for correcting the new inefficiencies universal mandates can never improve on any nash equilibria

different types of environmental regulations and heterogeneous influence on green productivity evidence from china this paper attempts to examine if the strong version of porter hypothesis is supported in china by investigating how different regulatory instruments and the relative stringency impact green productivity we use a slacks based measure sbm and luenberger productivity index accounting for undesirable outputs to evaluate the industrial green productivity growth rates of china s 30 provinces the estimates imply an unsustainable development model in china with significant regional differences by employing a panel threshold model and a province level panel dataset during 2000 2012 empirical results show that both command and control and market based regulation have a non linear relationship with and can be positively related to green productivity but with different constrains on regulation stringency there are double thresholds with the command and control and exists an optimal range of stringency for productivity improvement while a single threshold has been found with the market based regulation and its current stringency is reasonable for most of provinces moreover based on china s reality the productivity effect driven by market based regulation is much stronger than that of the command and control the mechanism of informal regulation is much more complicated consequently we find evidence to support the strong porter hypothesis that reasonable stringency of environmental regulations may enhance rather than lower industrial competitiveness

network software security and user incentives we study the effect of user incentives on software security in a network of individual users under costly patching and negative network security externalities for proprietary software or freeware we compare four alternative policies to manage network security i consumer self patching where no external incentives are provided for patching or purchasing ii mandatory patching iii patching rebate and iv usage tax we show that for proprietary software when the software security risk and the patching costs are high for both a welfare maximizing social planner and a profit maximizing vendor a patching rebate dominates the other policies however when the patching cost or the security risk is low self patching is best we also show that when a rebate is effective the profit maximizing rebate is decreasing in the security risk and increasing in patching costs the welfare maximizing rebates are also increasing in patching costs but can be increasing in the effective security risk when patching costs are high for freeware a usage tax is the most effective policy except when both patching costs and security risk are low in which case a patching rebate prevails optimal patching rebates and taxes tend to increase with increased security risk and patching costs but can decrease in the security risk for high risk levels our results suggest that both the value generated from software and vendor profits can be significantly improved by mechanisms that target user incentives to maintain software security

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

evaluating the efficiency of industrial environmental regulation in china a three stage data envelopment analysis approach abstract environmental regulation is of great concern to international academics and policy makers previous studies often regarded environmental regulation as an influencing factor when calculating eco efficiency or energy efficiency more attention should be given to the efficiency of environmental regulation especially in industrial field according to exiting studies industrial environmental regulation efficiency iere may be influenced by external environmental factors to explore the influence and obtain an actual efficiency this paper calculated iere in china by using the panel data of 30 regions from 2011 to 2015 the 12th five year plan period through the three stage data envelopment analysis approach firstly the undesirable slacks based model method was used to calculate the original iere secondly the economic base industrial structure urbanization level and education level were taken as external environmental variables and the effect of external environmental factors and stochastic disturbance were excluded thirdly the actual iere can be calculated after adjusting input values the results showed that china s iere was underestimated due to the impact from external environmental factors moreover the iere was more influenced by pure technical efficiency than scale efficiency the iere of each region varied thus targeted policies should be formulated according to local conditions this research provided a new analytical method for calculating environmental regulation efficiency the method can be applied either in other countries or in other sectors

heterogeneous impacts of regulatory policy stringency on the eu electricity industry a bayesian shrinkage dynamic analysis abstract environmental and technical efficiency in the electricity sector is a major focus of regulatory policies aimed at hastening greenhouse gas reduction and lowering energy prices for final consumers understanding the impact of market and environmental regulations on efficiency is crucial for the design and choice of policy packages at the national level the productivity response to regulations depends on unobserved country specific factors that current empirical analyses have not modelled in this framework we analyse the regulation effects on efficiency in the electricity sector for a panel of european union countries we explicitly consider the effects of the environmental regulation along with the market regulation our estimation strategy uses the bayesian shrinkage estimator which can deal with the bias aggregation problem and cross country heterogeneity it allows us to identify the different transmission channels through which regulatory policy is implemented the results highlight divergent behaviours at the country level the direct impacts of the market and environmental regulatory policies on productivity are negative around 2 7 and 2 3 respectively but the countries vary in the degree to which they are able to compensate these negative effects

why are convertible bond announcements associated with increasingly negative issuer stock returns an arbitrage based explanation while convertible offerings announced between 1984 and 1999 induce average abnormal stock returns of 1 69 convertible announcement effects over the period 2000 2008 are more than twice as negative 4 59 we hypothesize that this evolution is attributable to a shift in the convertible bond investor base from long only investors towards convertible arbitrage funds these funds buy convertibles and short the underlying stocks causing downward price pressure consistent with this hypothesis we find that the differences in announcement returns between the traditional investor period 1984 1999 and the arbitrage period 2000 september 2008 disappear when controlling for arbitrage induced short selling associated with a range of hedging strategies post issuance stock returns are also in line with the arbitrage explanation average announcement effects of convertibles issued during the global financial crisis are even more negative 9 12 due to a combination of short selling price pressure and issuer issue and macroeconomic characteristics associated with these offerings

externalities and compulsary vaccinations abstract this paper challenges the conventional wisdom that because of the free rider problem a case can be made for compulsary vaccination against infectious disease for a very general class of models requiring that all individuals be vaccinated is strictly dominated by free choice the market allocation is not optimum and in the full information optimum some individuals would be compelled to be vaccinated this allocation can be achieved by taxes and subsidies however the government can exploit the revelation properties of vaccination and achieve an even better allocation than the full information optimum

dynamic epidemiology and the market for vaccinations abstract the intent of this paper is to raise the question of how and when externalities can arise in the market for vaccinations static and dynamic models of such markets are developed and compared a special case in a continuous time dynamic framework is examined and is found to be efficient i e there is no externality this is in contrast to the results from the static formulation raising doubts about the suitability of a static approach these results indicate that the question of whether there are externalities in individual immunization decisions is more involved than is generally supposed

preventives versus treatments preventives are sold ex ante before disease status is realized while treatments are sold ex post even if the mean of the ex ante distribution of consumer values is the same as that ex post the shape of the distributions may differ generating a difference between the surplus each product can extract if for example consumers differ only in ex ante disease risk then a monopolist would have more difficulty extracting surplus with a preventive than with a treatment because treatment consumers having contracted the disease no longer differ in disease risk we show that the ratio of preventive to treatment producer surplus can be arbitrarily small in particular when the distribution of consumer values has a zipf shape and the disease is rare the firm s bias toward treatments can be reversed for example if the source of private information is disease severity learned ex post the difference between the producer surplus earned from the products can result in distorted rd the deadweight loss from this distortion can be as large as the entire producer surplus difference calibrations for hiv and heart attacks based on risk factors in the u s population suggest that the distribution of disease risk is sufficiently zipf similar to generate substantial differences between producer surplus from preventives and treatments empirically we find that proxies for the zipf similarity of the disease risk distribution are associated a significantly lower likelihood of vaccine development but not drug development jel codes o31 l11 i18 d42

adverse selection and convertible bonds informational asymmetries between a firm and investors may lead to adverse selection in capital markets this paper demonstrates that when the market obtains noisy information about a firm over time this adverse selection problem can be costlessly solved by issuing callable convertible bonds with restrictive call provisions such securities can be designed to make the payoff to new claimholders independent of the private information of the manager this eliminates the possibility of any dilution of equity or underinvestment and implements the symmetric information outcome in either a pooling or a separating equilibrium the same first best efficient outcome can also be implemented by issuing floating price and mandatory convertibles

stock price effects and costs of secondary distributions abstract this study does not support the view that a large number of shares can be sold at the prevailing market price and at a small cost a significant stock price decrease is observed at the initial announcement of secondary distributions the price declines are greater for offerings by officers and directors and for larger offerings but are significant for all types of sellers and for large and small offerings there is no significant price decline at the offering when secondaries are announced in advance underwriting and other selling costs are substantial and are positively related to relative offering size

preference heterogeneity in the structural estimation of efficient pigovian incentives for insecticide spraying to reduce malaria this paper bridges the theoretical and empirical literatures on the role of preference heterogeneity in characterizing externalities related to disease transmission we use a theoretical structure similar to locational sorting models which characterize equilibria in terms of marginal individuals who are indifferent between locations in our case the locations are binary consisting of whether or not to take a discrete preventative action individual heterogeneity arises in this structure due to variation in the costs and disutility associated with prevention we demonstrate application of this approach in the context of participation in insecticide based indoor residual spraying programs for malaria control in northern uganda we identify the parameters of our theoretical model using a stated preference choice experiment combined with estimates from published epidemiological studies the model implies that pigovian subsidies for participation in this context should decrease household malaria risk by 19 25 our approach can be applied to other bioeconomic externalities with spillovers from discrete preventative actions including agricultural pest management and the control of pest infestations and invasive species

why are governmental r d and private r d complements it is well known that government r d and private r d have a complementary relationship however no previous study has provided an explanation for why that complementary relationship exists this paper argues that infratechnology is the critical link between governmental and private r d and that the observed complementarity is the result of technical complementarity at the production level between funding infratechnology and knowledge sharing a theoritical framework based on this argument is developed and examined empirically for supporting evidence evidence of technical complementary is found as well as evidence that governmental r d stimulates the sharing of knowledge

linking induced technological change and environmental regulation evidence from patenting in the u s auto industry a b s t r a c t this article uses a carefully screened patent database in automobile emission control technologies and a detailed regulatory action analysis to examine firms innovation in response to u s technology forcing auto emissions standards enacted between 1970 and 1998 the study finds that under the performance based technology forcing pbtf auto emissions regulations both automakers and compo nent suppliers innovated and introduced more advanced emission control technologies for automobile applications the study also shows that stringent pbtf regulation temporarily induced domestic u s firms to become more innovative than foreign firms that operated in the local u s market during the early phase of the regulatory regime findings of this research strongly imply that government intervention in the form of technology forcing regulation can drive firms to invest in technological innovation

environmental regulation and the export dynamics of energy technologies abstract the pollution haven hypothesis affirms that an open market regime will encourage the flow of low technology polluting industries toward developing countries because of potential comparative advantages related to low environmental standards in contrast the hypothesis suggested by porter and van der linde claims that innovating firms operate in a dynamic competitive situation which allows global diffusion of environmental friendly technologies environmental regulation may represent a relevant mechanism through which technological change is induced in this way countries that are subject to more stringent environmental regulations may become net exporters of environmental technologies this paper provides new evidence on the evolution of export flows of environmental technologies across different countries for the energy sector advanced economies particularly the european union have increasingly focused on the role of energy policies as tools for sustaining the development path the kyoto protocol commitments together with growing import dependence on energy products have brought attention to the analysis of innovation processes in this specific sector the analysis uses a gravity model in order to test the determinants and the transmission channels through which environmental technologies for renewable energies and energy efficiency are exported to advanced and developing countries our results are consistent with the porter and van der linde hypothesis where environmental regulation represents a significant source of comparative advantages what strongly emerges is that the stringency of environmental regulation supplemented by the strength of the national innovation system is a crucial driver of export performance in the field of energy technologies

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

convertible call policies an empirical analysis of an information signaling hypothesis abstract this paper tests an information signaling hypothesis as a potential explanation for corporate convertible bond call policies and for the negative share price reaction to the announcement of the calls we test this hypothesis by trying to ascertain whether the information signaled is realized our results show an unexpected decline in the firm s performance subsequent to the call we also find significant negative cumulative returns during a sixty month period following the calls

the international economics of intellectual property right protection a welfare theoretic trade policy analysis abstract this paper provides an analytical construct for examining the trade policy effects of greater intellectual property protection in technology importing countries it is shown that two types of conflict are likely to arise between net technology importers and exporters the first relates to the level of protection with importers preferring a low level and exporters a high one the second conflict hitherto unexplored relates to the manner of protection with importers likely to prefer discriminatory regimes favoring local r d creation whereas exporters would prefer nondiscriminatory protection in importing countries

innovation and the international diffusion of environmentally responsive technology abstract new evidence is presented on environmental innovation and diffusion over the 1970s and 1980s at a global level a substantial amount of innovations occurred in the united states japan and germany the share of environmental patents in all patents varied between 0 6 and 3 and as such was higher than the corresponding share of pollution abatement expenditure in gdp japanese environmental innovation rates were consistently high certain plausible connections between environmental regulation and innovation also emerge across these three countries and over time innovation responded to pollution abatement expenditure an indicator of the severity of environmental regulations environmental patenting rates in developing countries were also high reaching 2 in many years in brazil developing country innovators obtained a non trivial number of patents most of which appear geared towards adapting imported technologies to local conditions however domestic innovation was only one path to new technologies imports of disembodied environmental technologies foreign patents registered in developing countries were substantial foreign patents were typically important or generic patents evidence also suggests that such patents protected intellectual property in equipment exported developing countries especially in east asia often chose to obtain technologies embodied in pollution abatement equipment

environmental protection innovation and price setting behavior in spanish manufacturing firms abstract in this paper we analyze the effects of environmental protection regulation on process and product innovation decisions and their impact on price setting behavior in spanish manufacturing firms throughout 2009 2014 to this end we estimate several discrete choice probit models using firm level data our results show a positive relationship between the existence of environmental regulations environmental expenditures as a proxy and innovation however the magnitude of the effects and their significance depend on the type of innovation and the size of the firms environmental regulation positively impacts process innovation only in large firms 200 workers while it positively impacts product innovation exclusively in small firms up to 200 workers taking into account innovation activities we additionally explore the behavior of product prices we obtain that process innovation increases the probability of reducing prices for both small and large firms while product innovation only raises the likelihood of increasing prices for the former finally we look into the determinants of investment in environmental protection and find a positive impact of environmental regulation

environmental innovations and firm profitability unmasking the porter hypothesis we examine impacts of different types of environmental innovations on firm profits following porter s sci am 264 4 168 1991 hypothesis that environmental regulation can improve firms competitiveness we distinguish between regulation induced and voluntary environmental innovations we find that innovations which do not improve firms resource efficiency do not provide positive returns to profitability however innovations that increase a firm s resource efficiency in terms of material or energy consumption per unit of output have a positive impact on profitability this positive result holds for both regulation induced and voluntary innovations although the effect is greater for regulation driven innovation we conclude that the porter hypothesis does not hold in general for its strong version but depends on the type of environmental innovation our findings rest on firm level data from the german part of the community innovation survey 2008 cis 2008

environmental regulation and environmental productivity the case of china abstract constrained by the dual mission of supporting industrial growth and reducing emissions china s traditional emission reduction oriented environmental policies unavoidably face a dilemma this study adopts the gml index to calculate china s industrial productivity by considering environmental factors in addition based on the assumption of industry heterogeneity the author examines the non linear relationship between china s environmental regulation and environmental productivity and calculated the optimal regulation environment for industries according to this study when impact of undesirable outputs pollutant emissions is considered environmental regulation and environmental productivity are positively correlated which to some degree validates the porter hypothesis at present environmental regulation has significant positive effects on clean production industries but shows a lag effect on pollution intensive industries the degree of environmental regulation and environmental productivity show an inverted u shaped relation and display three thresholds it should be noted however that the relationship between regulation and productivity may vary across industries these findings have clear policy implications rather than continually increasing the level of environmental regulation the government should establish standards for individual industries that emphasize flexibility
