Environmental regulations and innovation activity in UK manufacturing industries

We examine the relationship between environmental regulations and innovation, using data from UK manufacturing industry during 2000-2006. We estimate a dynamic model of innovation behaviour, and explicitly account for the likely endogeneity of our measure of the stringency of environmental regulations (pollution abatement costs). Our results indicate that while on the one hand environmental R&D and investment in environmental capital are stimulated by greater pollution abatement pressures, on the other hand there is not a positive impact of environmental regulation on total R&D or total capital accumulation. We find some evidence that this is because more stringent environmental regulations directly lower the optimal expenditure on non-environmental innovations. In addition, we find that environmental R&D may crowd out non-environmental R&D, although there is no evidence that environmental capital crowds out non-environmental capital.     

Environmental Regulations,Producer Responses,and Secondary Benefits: Carbon Dioxide Reductions Under the Acid Rain Program

This paper derives a production analysis framework for modeling secondary benefits from environmental regulation, i.e. induced changes in yet unregulated pollutants. We emphasize the various ways in which the producers can respond to environmental regulations, and evaluate them in terms of their costs and their generation of secondary benefits. An application on the US electricity sector illustrates our main point: In our case, abatement technologies that reduce regulated emissions while leaving the plants’ unregulated emissions unchanged appear to be among the least costly producer responses to the existing sulfur and nitrogen regulations, but at the expense of limited secondary reductions in carbon dioxide emissions. This finding raises questions about the magnitude of the much debated secondary benefits from future regulations on carbon dioxide emissions, since similar abatement technologies are currently being developed for carbon dioxide. With new environmental issues emerging over time, our findings suggest that regulators should signal the possibilities of new regulations on connected pollutants to producers. Such information may be relevant for producers when choosing current abatement strategies—with minor cost increases to deal with today’s issues, overall compliance costs for near-future environmental problems may be lowered.

Environmental regulation and trade pattern：a case of China

As a growing number of countries, including both developed and developing countries, have in recent yearstaken environmental regulation at different levels, a question of great concern has been raised： can the regulation alterthe existing trade volume and trade pattern, and ultimately drive pollution-intensive industries to countries with low-levelregulations or even those without regulations at all？ Starting from the three different propositions concerning therelationship between environmental regulation and trade pattern, this paper applies cointegration analysis and errorcorrection model to empirically testing the relationship between environmental regulation and trade in China during theperiod of 1985-2005. Our empirical results indicate that in the short run the collection of pollution discharge fees bearsa positive impact on the export share of clean products of total exports. Thus, higher pollution discharge fees raise theratio of clean products exports to total exports. This further indicates that more stringent environmental regulationpromotes the exports of clean products. In the long run pollution discharge fees are positively correlated with the exportshare of clean products but negatively associated with their import share. Such correlations imply that environmentalregulation tends to facilitate the international specialization in line with comparative advantages.     

The relationship between pollution abatement costs and environmental regulation: Evidence from the Chinese industrial sector

Since the 2000s, China has been trying to strengthen emission controls in response to increasing pollution problems. However, strict implementation of emission controls generates pollution abatement costs. Using regional data for 29 provinces in the Chinese industrial sector from 1995 to 2010, this study estimated the pollution abatement costs for each province through the measurement of environmental efficiency, by applying a directional distance function approach. Moreover, using panel data analysis, this study clarified whether there is a nonlinear relationship between pollution abatement costs and environmental regulations. The empirical results are as follows. The study confirmed that the burden of abatement costs tended not only to occur in the central and western regions but also to increase in the eastern region. Moreover, the nonlinear relationship is inverted U‐shaped; thus, pollution abatement costs increase, as a negative effect of environmental regulations, until a certain inflection point, after which they decrease.     

Environmental Regulations and Managerial Myopia

It has recently been claimed that, contrary totraditional neoclassical theory, suitably chosenenvironmental regulation is often beneficial for theregulated firms because it induces cost-reducinginnovations. I analyze the extent to which thisposition is compatible with microeconomic analysis. Itturns out that even in a framework in whichorganizational inefficiencies might lead tounderinvestment, environmental policy can onlyincrease firm profits if several very specificconditions are met. These conditions concern the typeof policy, the extent of inefficiencies, the costs ofpotential innovation projects and their effect onproductivity and abatement costs.     

Environmental regulation and technology transfers

This paper analyzes the situation in which a national government introduces environmental regulations. Within the framework of an international duopoly with environmental regulations, an environmental tax imposed by the government in the home country can induce a foreign firm with advanced abatement technology to license it to a domestic firm without this technology. Furthermore, when the domestic firm's production technology is less efficient than that of the foreign firm, the foreign firm may freely reveal its technology to the domestic firm. These improvements through the voluntary transfer of technology imply that environmental regulations have positive impacts on innovation.     

A Real Options Approach to Abatement Investments and Green Goodwill

In this paper we adopt the green goodwill argument as to why firms voluntarily invest in abatement capital. We investigate the effects on the abatement investment decision of changes in uncertainty about future green goodwill, competitor abatement investments, regulations, etc., using a real options framework. Our results indicate that increased uncertainty about consumers' willingness to pay for green products in the future discourage voluntary abatement investments. The model also suggests that voluntary abatement investments are promoted by an increased threat of regulation and competitor abatement investments. Furthermore, the benefit-cost ratio of the abatement investment project, at the point where it is optimal to invest, is independent of what regulatory regime (stringent or lenient) the firm operates in. We also conclude that despite the fact that voluntary abatement investment exists, there may still be room for environmental policy.     

中国环境规制对碳排放影响的空间异质性分析

基于1997—2017年中国30个省份的面板数据,将环境规制分成命令型、市场型和自愿型三类,以核密度估计分析碳排放分布的动态变化,采用空间杜宾模型探究了不同环境规制对碳排放影响的空间异质性。结果表明:1997—2017年中国三种环境规制与碳排放量变化表现同步增长,碳排放区域差异明显,命令型环境规制占据主体,市场型环境规制波动性变化特征明显,自愿型环境规制稳步增长;碳排放和环境规制具有明显的空间自相关特征,并且环境规制对邻近地区碳排放减少或增长的影响能力增强;三种环境规制对碳排放的影响均存在空间溢出,相比较而言,市场型环境规制的正向溢出效应最为明显,不同环境规制影响的区域差异特征表现为:命令型环境规制"东部>中部>西部",市场型环境规制"东部>西部>中部",自愿型环境规制"西部>东部>中部"。     

Regulating away competition: the effect of regulation on entrepreneurship and employment

Many scholars have worried that regulation deters entrepreneurship because it increases the cost of entry, reduces innovation in the regulated industry, and benefits large firms because they can overcome the costs of complying with regulations more easily than smaller firms. Using novel data on the extent of US federal regulations by industry and data on firm births and employment from the Statistics of US Businesses, we run fixed effects regressions to show that more-regulated industries experienced fewer new firm births and slower employment growth in the period 1998–2011. Large firms may even successfully lobby government officials to increase regulations to raise their smaller rivals’ costs. We also find that regulations inhibit employment growth in all firms and that large firms are less likely to exit a heavily regulated industry than small firms.     

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 S?o 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.     

Intertemporal Emission Permits Trading Under Uncertainty and Irreversibility

This paper analyzes the effect of emission permit banking on clean technology investment and abatement under conditions where the stringency of the future cap is uncertain. We examine the problem of heterogeneous firms minimizing the cost of intertemporal emission control in the presence of stochastic future pollution standards and emission permits that are tradable across firms and through time. A firm can invest in clean capital (an improved pollution abatement technology) to reduce its abatement cost. We consider two possibilities: that investment is reversible or irreversible. Uncertainty is captured within a two period model: only the current period cap is known. We show that if banking is positive and marginal abatement costs are sufficiently convex, there will be more abatement and investment in clean technology under uncertainty than there would be under certainty and no banking. These results are at odds with the common belief that uncertainty on future environmental policy is a barrier to investment in clean capital. Moreover, under uncertainty and irreversibility, we find that there are cases where banking enables firms to invest more in clean capital.     

政企合谋、环境规制与企业全要素生产率*

本文利用中国工业企业数据库和地级市层面的企业治污投资数据构建了一个2003—2007年的面板,实证检验了环境规制对企业全要素生产率的影响以及政企合谋在背后的作用。实证结果表明,用企业治污投资占工业增加值比重衡量的环境规制强度每上升1%,企业当期的生产率下降约1%。当政企合谋可能性上升时,环境规制对企业生产率的边际影响在减弱,说明政企合谋带来的监管放松和处罚不力弱化了环境规制对合谋企业生产率的影响。本文的政策启示在于中央政府应加强环保领域统一执法,破解囚徒困境式的环境规制。同时,本文的发现为环保机构监测监察执法垂直管理制度改革提供了合理性依据。     

Environmental Abatement Costs and Establishment Size

The impact of environmental abatement costs on the size distribution of manufacturing establishments in pollution-intensive industries is analyzed. Utilizing both state- and industry-specific measures of environmental regulation, a new and important interaction is discovered: Establishment size increases with state environmental abatement costs, but only in industries during periods of relatively high (national) pollution abatement intensity. Increased state environmental stringency during times when similar industries located in other states are not undertaking sufficient abatement expenditures leads to a decrease in establishment size.

Environmental regulations,induced R&D,and productivity: Evidence from Taiwan's manufacturing industries

This paper examines whether stringent environmental regulations induce more R&D and promote further productivity in Taiwan. Using an industry-level panel dataset for the 1997–2003 period, empirical results show that pollution abatement fees, a proxy for environmental regulations, is positively related to R&D expenditure, implying that stronger environment protection induces more R&D. On the other hand, pollution abatement capital expenditures do not have a statistically significant influence on R&D. Further evaluation of the influence of induced R&D by environment regulations on industrial productivity shows a significant positive association between them. This finding supports the Porter hypothesis that more stringent environmental regulations may enhance rather than lower industrial competitiveness.     

The impact of environmental regulation on productivity in German industries

The objective of this paper is to adjust a traditional total factor productivity (TFP) measure for the direct effect of environmental regulation on material and capital input. For this purpose we consider the fact that part of material input and pollution abatement capital have not been used to increase output but to cover the cost of using the environment as a factor of production. Therefore TFP growth rates are lower if part of the material input is allocated to abatement activities instead of producing output. We propose to treat compliance with environmental regulation as an unproductive input linked to the use of productive material input. Our aim is to answer and discuss two questions: How to measure the effect of environmental regulation on TFP, and does the effect matter. We examine data from 1975–1991 for ten pollution intensive German industries.We would like to thank Cornelia Oßwald for valuable research assistance. We are especially grateful to two anonymous referees for many helpful comments.     

Growth, welfare and transitional dynamics in an endogenously growing economy with abatement labor

This paper sets up a simple endogenous growth model that highlights the importance of the endogenous labor-leisure choice and the allocation between production labor and abatement labor. We show that, in contrast to the common notion (e.g. [Bovenberg, A.L., Smulders, S., 1996. Transitional impacts of environmental policy in an endogenous growth model. International Economic Review 37, 861–893] and [Bovenberg, A.L., de Mooij, R.A., 1997. Environmental tax reform and endogenous growth. Journal of Public Economics 63, 207–237]), the existence of an environmental production externality is a sufficient (but not necessary) condition for environmental policies to stimulate economic growth if the labor-leisure choice is endogenously determined. In particular, since there are complementarities between public abatement and private abatement, the public abatement expenditure will have a more powerful enhancing effect on economic growth when it is accompanied by more efficient private abatement. This result also leads to a corollary to the effect that it is easier to achieve double dividends in terms of enhancing both growth and welfare if the endogenous labor-leisure choice is taken into account.In our dynamic analysis, we show that if public abatement is substantially large, dynamic indeterminacy may occur despite the absence of a positive labor externality and interestingly, this is more likely to be the case when abatement labor plays a more significant role. Besides, the transitional effects of an increase in public abatement are also investigated.     

自愿参与型环境规制与企业技术创新——公众关注度和市场进程的调节作用

“波特假说”有效性一直是学术界颇具争议的话题，然而现有文献对于自愿参与型环境规制与企业技术创新的关系讨论较少，也缺乏对其作用情景因素的关注。基于2011—2019年730家沪深A股上市企业面板数据，采用负二项回归模型和倾向得分匹配法，分析我国上市企业在市场化进程影响下，自愿参与型环境规制、公众关注度对企业技术创新的影响。结果发现，自愿参与型环境规制对企业技术创新具有正向影响；公众关注度在自愿参与型环境规制对企业技术创新的影响过程中起正向调节作用；自愿参与型环境规制、公众关注度和市场化进程交互项结果表明，企业位于市场化程度较高地区时，公众关注度对自愿参与型环境规制与企业技术创新的调节作用更显著。结论不仅丰富了“波特假说”相关研究，还为我国企业提高信息共享意识以及政府优化市场环境提供了微观证据。     

Do environment regulations matter for EU-MENA trade?

This study examines the impact of environmental regulations stringency on agricultural trade between European Union (EU) and Middle East and North Africa (MENA countries). Using a gravity model and applying the zero-inflated Poisson (ZIP) model, we estimate the impact of environmental regulations stringency on bilateral agricultural exports between 28 EU and 20 MENA countries during the period 2001–2014. The results have showed that environmental regulations do matter for agricultural trade between both regions because in the presence of excessive zero trade observations, they act as significant fixed export costs that affect the probability of trade. More stringent environmental regulations stimulate innovative efforts in cost-saving green technologies, which increase productivity and positively affect agricultural exports. The results have favoured the revisionist Porter hypothesis (PH), according to which environmental regulations may stimulate innovative efforts, which mitigate the negative effects of higher fixed abatement costs and enhance trade competitiveness.     

SO2 policy and input substitution under spatial monopoly

Following the U.S. Clean Air Act Amendments of 1990, electric utilities dramatically increased their utilization of low-sulfur coal from the Powder River Basin (PRB). Recent studies indicate that railroads hauling PRB coal exercise a substantial degree of market power and that relative price changes in the mining and transportation sectors were contributing factors to the observed pattern of input substitution. This paper asks the related question: To what extent does more stringent SO₂ policy stimulate input substitution from high-sulfur coal to low-sulfur coal when railroads hauling low-sulfur coal exercise spatial monopoly power? The question underpins the effectiveness of incentive-based environmental policies given the essential role of market performance in input, output, and abatement markets in determining the social cost of regulation. Our analysis indicates that environmental regulation leads to negligible input substitution effects when clean and dirty inputs are highly substitutable and the clean input market is mediated by a spatial monopolist.
