Environmental regulation and intra-industry trade

The paper analyses complex interactions between intra-industry trade (IIT) and environment by extending Krugman's model of monopolistic competition and trade. It is found that an increase in exogenous environmental tax by a country leads to a fall in its output (the scale effect) and aggregate pollution, and an increase in its number of varieties (the selection effect). With IIT, if Home is a net exporter, an increase in its environmental stringency leads to a negative scale effect, which reduces its export demand and raises its import demand. In contrast, a positive selection effect reduces its import demand. However, the first-order scale effect on exports dominates the second-order effect on imports, implying a rise in Home's share of IIT with Foreign. The opposite holds true when Home is a net importer. Furthermore, the impact of a rise in environmental tax on aggregate welfare comprises the following counteracting effects: a negative scale effect, a positive selection effect, a lower level of aggregate pollution and a higher environmental tax revenue in autarky, and two additional effects, namely, changes in the level of exports and imports, under free trade. The overall change in aggregate welfare, in both autarky and free trade, is in general ambiguous.     

Environmental regulation and international trade

In this paper, we investigate how a country's choice of environmental policy instrument affects the international competitiveness of its firms. We show that in a Cournot-Nash equilibrium, the total market share of firms regulated through tradeable emission permits increases relative to that of the firms operating under command and control due to better allocation of total abatement among the firms in the country. Our work suggests that free trade situations should not only result in similar environmental standards but also in similar regulatory regimes. It may come as no surprise that the environmental authorities in Canada are seriously considering following the United States in instituting a tradeable emission permits mechanism.Most of the work was completed during the time that E.S.

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.     

环境规制对现存企业迁移行为的影响研究

在城市化发展过程企业渐渐由中心区迁往外围区域,鲜有研究从这一视角观察企业迁移行为。本文从环境规制的角度对现存企业的迁移行为进行了探讨。实证分析发现在省级层面,废水污染费征收率提升显著减少企业在城市之间迁移的数量,废气污染费征收率提高增加企业城市之间迁移的数量。在企业层面环境规制增强显著提升企业在县区之间迁移的概率。利用国家贫困县名录,进一步发现废气污染费率增加显著提升企业往县和贫困县迁移的概率。进一步分析发现加入WTO、2003年污染费征收改革后污染费上升时企业显著提高向贫困县迁移的概率。最后本文发现环境规制提高了企业的创新水平以规避环境规制成本从而降低了迁移的概率。     

Environmental regulation and production structure for the Korean iron and steel industry

The most important obstacle to studying the structure of production under environmental regulations is the lack of price data for abatement capital. The use of a restricted cost function circumvents the problem of missing prices for some inputs. This paper estimates a restricted cost function for the Korean iron and steel industry based on the quantities of raw material and abatement capital over the period 1982–2001. The Allen elasticities of substitution between abatement capital and other inputs are calculated, and the shadow price of abatement capital is derived.     

Environmental regulation of technically inefficient firms

This paper presents a model in which a technically inefficient firm is responsible for the emissions of pollutants. We derive second-best regulatory schemes (tax and quota) assuming that the firm’s technical efficiency is unknown to the regulator.     

Environmental regulation and firm location choice in China

How may environmental regulation affect firm location choice? While this question has generated great research interest from high-standard, industrial economies, in this article we turn the spotlight to low-standard, developing countries and use China’s Census of Manufactures data during 2003–2008 to explore how firms with different ownership, during different policy regimes as well as from different industries may respond to environmental regulations in different ways. Results show environmental stringency has a positive effect on state-owned enterprises’ location choice during 2003–2005, but the effect becomes insignificant during 2006–2008. Private-owned enterprises, foreign-owned enterprises and collective-owned enterprises are more likely to enter areas with less stringent environmental regulations during 2003–2005. However, this pattern is reversed for the period of 2006–2008. Furthermore, the above relationships are more pronounced for firms in polluting industries.     

Environmental regulation and the productivity of Japanese manufacturing industries

This paper attempts to provide empirical evidence on issues concerning: (a) the effect of the stringency of environmental regulations (as measured by pollution control expenditures) on innovative activity (as measured by R&D expenditures) and on the average age of capital stock and (b) the productivity enhancement effect of environmental regulations in Japanese manufacturing industries. The empirical findings in the paper show that the pollution control expenditures have a positive relationship with the R&D expenditures and have a negative relationship with the average age of capital stock. It is also shown that increases in R&D investment stimulated by the regulatory stringency have a significant positive effect on the growth rate of total factor productivity.     

Environmental regulation and investment: Evidence from European industry data

This paper contributes to the empirical literature on the effects of environmental regulation on investment. In particular, we ask whether and how strongly an industry's investment responds to stringency in environmental regulation. Environmental regulation is measured as (i) an industry's total current expenditure on environmental protection, and (ii) a country-industry's revenue from environmental taxes. Focusing on European data of manufacturing industries between 1998 and 2007, we estimate the differential impact of environmental stringency on four types of investment: gross investment in tangible goods, in new buildings, in machinery, and in ‘productive’ investment (investment in tangible goods minus investment in abatement technologies). Both environmental variables enter positively, and their quadratic terms exhibit significantly negative parameter estimates. This, in turn, indicates a positive but diminishing impact of environmental regulation on investment.     

Environmental regulation,political incentives,and mortality in China

China enacted an environmental regulation policy in 1998, the “Two Control Zones” (TCZ) policy, to control air pollution in selected cities. Using a panel dataset of 208 prefectural cities for 2001–2012, this study applies a difference-in-differences approach to examine the policy's impact on mortality and identify the role of political incentives. We find the following aspects. (1) The policy significantly reduces mortality in TCZ cities relative to that in non-TCZ cities by 0.305‰ in the period when the policy is strictly enforced. On average, it translates into a 5.2% reduction in mortality. (2) The effect is particularly salient in the years when local officers are evaluated for political promotion and/or when they face stronger pressure for promotion, thus suggesting that political incentives play an important role in determining the effectiveness of environmental regulation policy. (3) The policy reduces industrial emissions of sulfur dioxide instantaneously, while the accumulation of which eventually leads to a lagged reduction in mortality in the cities. (4) The policy yields health benefits worth 1.1 trillion yuan for the treatment period in our sample (i.e., 2006–2012), which accounts for approximately 5.1% of GDP in 2006.     

Environmental regulation and U.S. states' technical inefficiency

Using data on 48 states from 1982–1994, we estimate the impact of environmental regulation on technical inefficiency of U.S. states' manufacturing sector. The result indicates that environmental stringency has significant and positive impacts on U.S. states' technical inefficiency.     

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.     

Environmental regulation and trade openness in the presence of private mitigation

Acknowledging the differential ability of individuals to privately mitigate the consequences of domestic pollution for their health is essential for an understanding of their demands for regulation of the environment and of trade in dirty goods, and for analysis of the implications of these demands for equilibrium policy choices. In a small open economy with exogenous policy, we first explain how private mitigation at a cost results in an unequal distribution of the health consequences of pollution in a manner consistent with epidemiologic studies, and consequently how the benefits and costs of trade in dirty goods interact with choices concerning private mitigation to further polarize the interests of citizens concerning environmental stringency. The economy is then embedded in a broader political economy setting, and simulated to investigate the role of private mitigation in shaping political equilibria. We show that when citizens can choose between mitigating the health consequences of domestic pollution privately and reducing pollution through public policy, the same polarization of interests underlies equilibrium policy choices in both democratic and autocratic regimes.     

Environmental regulation: choice of instruments under imperfect compliance

Compliance is an important issue in environmental regulation. We discuss some of the key elements of the problem and analyze a situation where emissions are not random and firms are risk-neutral. We study the firm’s decision on emissions and compliance when the environmental regulation is based on standards and the enforcement agency audits the firm with a certain probability. We compare total emissions when environmental regulation is based on different instruments: standards, taxes, and tradable permits. We show that when compliance is an issue, environmental taxes are superior to the other instruments, and we analyze the (static) efficiency of the solution. This paper originated from the AEE/REE presidential address for the XXX Simposio de Análisis Económico (Murcia 2005). It builds on the research project on optimal enforcement in environmental problems done in collaboration with David Pérez-Castrillo. I would like to thank David Pérez-Castrillo and Pau Olivella for their useful comments.

Environmental taxation for environmental regulation and fiscal policy: An analysis of a Clinton-type BTU tax

This paper provides an empirical study of energy taxes for achieving environmental and fiscal policy objectives. Based on an energy tax structured like Clinton's 1993 BTU tax proposal, we demonstrate that the optimal tax will be higher the greater the environmental costs associated with energy consumption and the larger the economic distortions associated with alternative revenue-raising policies. Greater environmental damages and higher revenue-raising costs also have a fiscal policy implication; they shift the least-cost tax mix for raising additional revenue toward energy taxes and away from conventional tax alternatives.The authors wish to acknowledge the assistance of two anonymous referees, who provided very helpful feedback. We also wish to acknowledge outstanding research assistance from Tracy Terry of the School of Public and Environmental Affairs, Indiana University Bloomington.

Environmental regulation and safety outcomes: Evidence from energy pipelines in Canada

This paper investigates the effects of more stringent environmental regulation—specifically, paying amortized abandonment fees as accrued and absolute liability for adverse events—on the safety performance of Canadian oil and gas pipelines. We construct a comprehensive dataset that includes pipeline adverse events, throughput, and regulatory intensiveness for fourteen federally-regulated energy pipelines in Canada. We find that abandonment fees are significantly and positively associated with pipeline events. On average, a 1% increase in abandonment fees is associated with 1.3 more events per month. In contrast, establishing absolute liability is associated with significant decreases in the number of pipeline events: on average, absolute liability is responsible for eliminating 80% of quarterly events for Canadian major oil pipelines and 20% for smaller pipelines.     

Standardization and variety

In the tradeoff between standardization and variety, there can be too much or too little variety. The latter possibility can only happen if there are several equilibria.     

Environmental regulation and profitability: An application to Swedish pulp and paper mills

In this paper we analyze the impact on firm profits of the environmental regulations in the Swedish pulp and paper industry. The approach taken is a non-parametric programming model of the technology. A feature of this industry is that environmental regulations are determined individually for each mill. A question, then, is if these individual regulations have a similar impact on firm profits. The approach in this paper allows us to calculate both the regulated and unregulated profits, which means that the severity of the regulations, in terms of foregone profits, can be calculated for each mill. The empirical result shows that the impact on the mills varies substantially, and that the burden from the regulations is less severe in 1990 than in 1989.
