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

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

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

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

effects of pollution control on industry productivity a factor demand approach four major manufacturing industries are examined the abatement effect on capital and labor productivity are determined from parameters of a system of factor demand equations which allow for disequilibrium in factor markets the system is estimated for each industry with annual time series data from 1960 to 1980 abatement requirements were found to retard both average capital productivity and average labor productivity in three of the four industries paper chemicals and primary metals for several industries in which factor productivity was slower after 1973 environmental controls accounted for a significant proportion of that slow down

an empirical analysis of the co2 shadow price in chinese thermal power enterprises abstract this paper estimates the shadow price of co2 and explores its determinants for thermal power enterprises in china using a parametric quadratic directional distance function we evaluate the inefficiency and shadow price of co2 for 124 power enterprises in 2004 applying deterministic and econometric methods a regression analysis is undertaken to examine the factors that drive shadow prices our results indicate that there are large inefficiencies in terms of electricity production and co2 emissions the shadow price is a negative function of firm size age and coal share and is positively correlated with the technology level this correlation between shadow prices and its determinants is not sensitive to changing assumptions regarding directional vectors although such changes do alter the distribution of shadow prices the large variation witnessed in shadow prices across power enterprises argues in favor of market based regulation such as an emissions trading system as opposed to the command and control regulation currently used in china to minimize overall abatement cost

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

clean and productive empirical evidence from the german manufacturing industry abstract in view of the controversial policy debate on green growth and corresponding stimulus packages we empirically investigate the production effects of environmental investment as well as of environmental and energy expenditures using a panel dataset of german manufacturing sectors our econometric analysis identifies a positive impact of environmental investment on production growth in contrast our estimation results cannot support the hypothesis of positive production impacts induced by environmental or energy expenditures we thus conclude that environmental regulation should in particular stimulate environmental investment in order to be compatible with the pursuit of production growth

software industry entry strategies for developing countries a walking on two legs proposition abstract two themes run through the following analysis first countries without a relatively active and up to date software sector will find it increasingly difficult to catch up in terms of capital outlays labor skills and the growing importance of technology changes organization and management in software production they will not have for example software management experience to undertake increasingly large and complex software development projects a quality consciousness and the institutional and support infrastructure for marketing and forming product development alliances with dominant international firms in the sector second the learning curves for domestic and international market activities are quite different the domestic software market being an important base for skills experience and establishing a track record that may later be applied to exports two developing countries india and brazil have used different development strategies for their software industries and as could be expected with disparate results both the brazilian and the indian software industries are trying to walk on one leg the domestic leg in the case of brazil and the export leg in the case of india both countries have at least some potential for moving to a two legged model assessment of these two industries suggests that countries need to pay more attention to domestic opportunities since these have high returns in terms of gaining experience and innovation in software production and provide training that allows a broadening of software exports

why can modern governments tax so much an agency model of firms as fiscal intermediaries we develop an agency model explaining why third party information reporting by firms makes tax enforcement successful while third party reporting would be ineffective with frictionless collusion between firms and employees collusive evasion is impossible to sustain in firms with many employees and accurate business records as any single employee may reveal evasion we embed our agency model into a macro model where the number of employees grows with development showing that the tax take evolves as an s shape driven by changes in third party information we show that our model is consistent with a set of stylized facts on taxation and development

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

using differences in knowledge across neighborhoods to uncover the impacts of the eitc on earnings we develop a new method of estimating the impacts of tax policies that uses areas with little knowledge about the policy s marginal incentives as counterfactuals for behavior in the absence of the policy we apply this method to characterize the impacts of the earned income tax credit eitc on earnings using administrative tax records covering all eitc eligible lers from 19962009 we begin by developing a proxy for local knowledge about the eitc schedule the degree of sharp bunching at the exact income level that maximizes eitc refunds by individuals who report self employment income the degree of self employed sharp bunching varies signi cantly

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

expected consumer s surplus and the welfare effects of price stabilization suppose a consumer faces a price which is uncertain ex ante a question which often arises is whether the consumer would benefit from a stabilization policy under which the price would then be fixed and known with certainty many authors have addressed this question by calculating the expected compensating variation of the price change others have used expected marshallian consumer s surplus often with the explanation that it is a good approximation to expected compensating variation 2 an important unresolved issue however is whether expected compensating variation does in fact provide a valid ranking of stochastic prices against stabilized prices i e a ranking in agreement with that given by expected utility in section 2 we demonstrate that expected compensating variation is not in general a valid utility indicator in essence while utility comparisons under uncertainty require the use of the cardinal properties of von neumannmorgenstern utility functions the expected surplus measures depend only on ordinal preference rankings expected compensating variation then is completely insensitive to and cannot reflect the precise factor of interest in suchstudies the consumer s attitudes toward risk we then derive a set of restrictions on the utility function which are necessary in order for expected compensating variation to be a valid measure we see that price stabilization policies can only be evaluated with compensating variation if consumer preferences are assumed to satisfy quite stringent requirements this is in constrast to the familiar certainty case in which compensating variation always provides correct rankings

differentiated regulation the case of auto emissions standards this paper presents an analysis of automotive emissions regulation that explicitly considers the link between regulation and the composition of the vehicle stock the adoption of more stringent emissions standards for new vehicles is shown to prolong the retention of old high emission rate vehicles in the fleet for this reason tighter new source standards actually increase aggregate emissions in the short run this result is of general as well as specific interest given the widespread use of differentiated regulatory tools incorporating a bias against new sources in many regulatory programs 3 references 1 table

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

import substitution and late industrialization latin america and asia compared abstract asymmetries between the profit risk perceptions of foreign and domestic investors are unavoidable aspects of late development import substitution strategies that try to advance industrialization by compensating for the asymmetries have therefore been part of the development efforts of asian and latin american nics current explanations of the greater success of asian nics with isi are examined and an alternative is advanced that stresses the impact of culture and history on consumer preference formation and through this on the survival and modernizing of craft industry partial evidence plus suggestions for deeper testing are offered

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

issue in pollution control interplant cost differences and economies of scale debate on interplant pollution control cost differences focuses on the question of whether a system of taxes or transferable discharge permits should require those plants with low treatment costs to control a higher share of effluents another issue under debate is whether those industries with a large minimum size may be effectively barred by pollution control requirements evidence of the inefficiency of present institutional arrangements is shown by studying production function estimations of 30 pulp and paper mills in wisconsin and michigan a more efficient reallocation of pollution control resources could be effected with more market oriented regimes 58 references 6 tables dck

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

using notches to uncover optimization frictions and structural elasticities theory and evidence from pakistan we develop a framework for nonparametrically identifying optimization frictions and structural elasticities using notches discontinuities in the choice sets of agents introduced by tax and transfer policies notches create excess bunching on the low tax side and missing mass on the high tax side of a cutoff and they are often associated with a region of strictly dominated choice that would have zero mass in a frictionless world by combining excess bunching observed response attenuated by frictions with missing mass in the dominated region frictions it is possible to uncover the structural elasticity that would govern behavior in the absence of frictions and arguably capture long run behavior we apply our framework to tax notches in pakistan using rich administrative data while observed bunching is large and sharp optimization frictions are also very large as the majority of taxpayers in dominated ranges are unresponsive to tax incentives the combination of large observed bunching and large frictions implies that the frictionless behavioral response to notches is extremely large but the underlying structural elasticity driving this response is nevertheless modest this highlights the inefficiency of notches by creating extremely strong price distortions they induce large behavioral responses even when structural elasticities are small

impact of corruption in public sector on environmental quality implications for sustainability in brics and next 11 countries abstract this study investigates the impact of corruption in public sector on carbon emissions in presence of energy use segregation following the environmental kuznets curve ekc framework the study has been carried out for brazil russia india china south africa brics and next 11 countries over the period of 1990 2017 along with the finding of inverted n shaped ekc for both the cases we find that incidents of corruption enhance environmental degradation by reducing the positive impact of renewable energy consumption on environmental quality and increasing the negative impact of fossil fuel consumption this study has also divulged that the corruptive practices are more prone in case of the countries where the development is mature and institutionalization is more stringent based on these findings we suggest that environmental policies should take account of the corruption and thereby making the policies more robust and effective

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

case study evidence that direct regulation remains the main driver of industrial pollution avoidance and may benefit operational efficiency abstract environmental regulation is required to reduce industrial pollution to levels that are socially acceptable and economically efficient but there is debate over the most efficient form of such regulation typically a limited range of environmental and economic parameters are accounted for in the econometric studies that inform that debate this paper integrates evidence from two separate studies to assess a broad range of parameters related to the efficiency of industrial environmental regulation questionnaire responses from 25 italian manufacturers of building chemicals and 28 irish pharmaceutical manufacturers provided evidence on the environmental effectiveness and operational impacts of different regulatory instruments combined with extensive emissions data from irish pharmaceutical manufacturers survey results enabled a quantitative estimation of pollution avoidance specifically attributable to direct regulation the monetised social benefit of avoided pollution was found to be equal to direct compliance costs chemical manufacturers in italy and ireland stated that direct regulation is a more important driver of industrial environmental performance than economic or voluntary regulation and their responses indicated that direct compliance costs may be countered somewhat by stimulated operational improvements it was concluded that direct regulation is an effective approach for multi pollutant control in an industrial context and that the efficiency of such regulation may be underestimated in studies that do not consider the full range of pollutants and operational effects

assessing the impact of formal and informal regulations on environmental and economic performance of brazilian manufacturing firms this study investigates the impact of formal and informal regulations on environmental and economic performance of brazilian manufacturing firms we adopt a dual approach where production technology is represented by a cost function approximated by a translog form pollution is considered as a negative by product that can be modified trough using either formal regulation inspections or sanctions or informal regulation community pressure a simultaneous equation model is estimated by three stage least squares on a sample of 404 industrial establishments located in the state of sao paulo brazil we show that pollution abatement costs for the brazilian manufacturing sector are different from zero which suggests that pollution emissions are affected by environmental regulation we also demonstrate that environmental performance of firms is jointly affected by formal and informal regulation lastly formal regulation is largely influenced by informal regulation and more specifically by community pressure

synchronizing export orientation with import substitution creating competitive indigenous high tech companies in china summary this paper examines how the synergy between china s domestic and the international market has affected its most competitive indigenous companies through case study in china s ict sectors in the 1990s the paper shows that when export upgrades and domestic market growth intersect in timing and sectors that is when they synchronize chinese companies found conditions most favorable to compete with foreign companies within the domestic market the synchronization has significant impact on sectors for both mature products and technologically advanced products it is thus necessary to reexamine the role of import substitution practices under the new context of globalization and in conjunction with exports

differential environmental regulation effects on electric utility capital turnover and emissions this paper tests the hypothesis that differential regulations reduced the rate of capital turnover in the electric utility industry resulting in increased emissions of sulfur dioxide based on a sample of forty four privately owned electric utilities operating over the period 1969 83 the authors results indicate that 1 regulation increased the age of capital by an average of 3 29 years 24 6 percent 2 increases in the age of capital have no statistically significant impact on emissions and 3 in the absence of regulation emissions would have increased by 3 79 tons per million kwhs 34 6 percent copyright 1993 by mit press

economic liberalization and the computer industry comparing outcomes in brazil and mexico abstract market liberalization has been carried out by many developing countries in the hopes of stimulating trade investment and technology transfer in order to analyze the impacts of liberalization on a specific industry sector this paper compares the experiences of brazil and mexico in liberalizing the computer industry in the 1990s the authors conclude that liberalization leads to lower prices and more rapid diffusion of computer use throughout the economy but at a cost to domestic computer firms who were harmed by foreign competition both countries saw an increase in computer production but mexico s production was mainly for export to the united states while brazil was producing for the domestic market the differences between outcomes in the two countries have been determined more by environmental factors than by the nature and pace of liberalization

pollution abatement and productivity growth evidence from germany japan the netherlands and the united states the passage of environmental legislation was accompanied by concerns about its potential detrimental effect on productivity we assume inputs can be assigned to either abatement activities or good output production this allows us to specify regulated and unregulated production frontiers to determine the association between pollution abatement and productivity growth we then employ our assigned input model to determine the association between productivity and abatement activities for manufacturing industries in germany japan the netherlands and the united states

do environmental regulations hamper productivity growth how accounting for improvements of plants environmental performance can change the conclusion abstract many economists maintain that environmental regulations hamper productivity growth a view supported by several empirical studies on industry or state level data however there is little research of the relationship between the stringency of environmental regulation and productivity growth at the plant level and the results of the few existing studies are ambiguous moreover the measures of productivity growth applied in previous studies do not credit plants for emission reductions and this may result in understatement of productivity growth we perform regression analyses of productivity growth on regulatory stringency using plant level data to credit a plant for emission reductions we include emissions as inputs when calculating an environmental malmquist productivity index emi and do not include emissions when calculation the traditional malmquist productivity index mi the regression analyses show that the overall effect of the regulatory stringency faced by plants on plants productivity growth is statistically insignificant when mi is applied to measure productivity growth however when we apply emi the effect is positive and statistically significant this indicates that not accounting for emission reductions when measuring productivity growth can result in too pessimistic conclusions regarding the effect of regulatory stringency on productivity growth

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
