International production fragmentation,trade in intermediate goods and environment

This paper examines the implications of growing international production fragmentation-induced trade in intermediate goods on environmental quality. Specifically, by making use of a general equilibrium framework, this paper explores the link between trade in intermediate goods and pollution in a setting of endogenous environmental policy. The paper shows that international trade in intermediate goods, through an increase in the number of components available to the international producers, affects the level of pollution and environmental quality. Specifically, developed countries may reduce pollution at the cost of more pollution in developing countries.     

Inequality,growth, and environmental quality trade‐offs in a model with human capital accumulation

This paper develops a simple endogenous growth model where pollution exposure and vulnerability are unequally spread across the population, and growth and distribution are endogenous. In this set‐up, we investigate whether trade‐offs between growth, distributional, and environmental concerns may emerge. We show that a tighter environmental policy reduces income inequality and can improve both growth and total welfare. Immediate welfare losses, though, do occur, and are larger for countries that start at low levels of environmental quality (e.g. developing countries).     

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.     

FDI and the Capital Intensity of "Dirty" Sectors: A Missing Piece of the Pollution Haven Puzzle

In an increasingly integrated world, falling trade barriers mean that the role environmental regulations play in shaping a country's comparative advantage is greater than ever. This has lead to fears that “dirty” industries will relocate to developing regions where environmental regulations may be less stringent. A number of reasons have been offered to explain why, despite anecdotal evidence and the predictions of theoretical studies, little empirical verification for the existence of pollution havens has been found. Little attention, however, has been paid to the capital intensity of pollution intensive sectors. We investigate the relationship between US outward FDI and factor endowments across sectors to two developing countries. We highlight the role of capital and believe it partially explains why pollution havens are not more widespread. Our approach also highlights those countries that are likeliest to become pollution havens. A multivariate analysis reveals some evidence of pollution haven consistent behavior.

Open-access renewable resources and pollution: Trade and policy implications in a two-country model

We examine the interaction between the relative inter-industry pollution externality and resource stock externality of harvesting in deciding trade patterns and welfare gains from trade in a two-country model (less-developed countries) with renewable resources in the absence of resource management. This paper focuses on the impacts of trade policies on resource conservation and welfare outcomes in two countries with different environmental management regimes. Differences in pollution management standards between both countries determine the direction of trade flow and gains from trade in a diversified production case. The country with a lower pollution intensity parameter, an exporter of resource goods, certainly experiences welfare loss in the post-trade steady-state and may also suffer a decline in utility throughout the transition path. However, a country with higher pollution intensity and importers of resource goods tend to gain from trade. Under national open-access resources, given that pollution is regulated up to a certain point in both countries, this study finds that implementing better restrictions on only one externality factor is not optimal from a post-trade welfare perspective. Lastly, from the point of view of policy suggestion, this paper offers an optimal trade policy that the economic and environmental effects of enforcing import tax on resource goods are likely to be Pareto-improving consequences compared to the implications of using an export tax.     

Does ecologically unequal exchange occur?

The hypothesis of ecologically unequal exchange posits that low and middle income developing nations maintain an ecological deficit with wealthy developed nations, exporting natural resources and high impact commodities thereby allowing wealthy economies to avoid operating ecologically impactful industries at home. In this survey we assess the footprint of consumption of 187 countries using eight indicators of environmental pressure in order to determine whether or not this phenomenon occurs. We use input–output analysis with a new high resolution global Multi-Region Input–Output table to calculate each trading pair's balance of trade in biophysical terms of: GHG emissions, embodied water, and scarcity-weighted water content, air pollution, threatened species, Human Appropriated Net Primary Productivity, total material flow, and ecological footprint. We test three hypotheses that should be true if ecologically unequal exchange occurs. One: The inter-regional balance of trade in biophysical terms is disproportional to the balance of trade in financial terms. We find this is true, though not strongly so. Two: Exports from developing nations are more ecologically intensive than those from developed nations. We find this is true. Three: High-income nations disproportionately exert ecological impacts in lower income nations. We find this is false: high income nations are mostly exporters, not importers, of biophysical resources.     

Trade liberalization in environmental goods

Trade negotiations have started to pay attention to liberalization in environmental goods (EGs), whose production may require dirty intermediate goods. We construct a two-country trade model to explore the effects of trade liberalization in EGs on the local pollution, the global environment and welfare in the presence of such an environmental conundrum. We find that countries do not necessarily benefit from trade liberalization in EGs in the absence of an environmental policy. With the assistance of an upstream pollution tax, trade liberalization in EGs improves each country's welfare. This result holds independent of whether the upstream market is competitive or not, or whether we have upstream trade across countries. For asymmetric countries, trade liberalization in EGs improves the world welfare and the welfare for the country if it has a smaller demand for EGs; or experiences less damage from the production of dirty inputs; or values environment improvement more.     

Strategic Environmental Policies and the Gains from Trade Liberalization

The literature on strategic environmental policy has not fully addressed welfare effects of trade liberalization from autarky. In a reciprocal market model of duopoly with transboundary pollution, we study how reductions in transport costs and import tariffs affect the Nash‐equilibrium welfare of an environmental policy game as compared to any initial state including autarky. We show three patterns of gainfulness of trade depending on the interaction between marginal damage from pollution and the degree of transboundary pollution.     

The trade-induced degradation hypothesis

This paper develops a simple two-sector dynamic model to examine the effects of international trade when government policy regarding the environment is short sighted, but still responsive to changes in income levels and in the quality of the environment. We show that free trade can usher in a negatively reinforcing cycle of increased pollution, lower environmental quality, and lower real incomes. Such cycles are not possible in autarky. We link the potential for trade to cause ‘large’ environmental consequences to the structure of tastes and technologies and the attributes of industrial pollution.     

Developing Country Second‐Mover Advantage in Competition Over Environmental Standards and Taxes

We show that, in competition between a developed country and a developing country over environmental standards and taxes, the developing country may have a “second‐mover advantage.” In our model, firms do not unanimously prefer lower environmental standard levels. We introduce this feature to an otherwise familiar model of fiscal competition. Four distinct outcomes can be characterized by varying the marginal cost to firms of an environmental externality: (1) the outcome may be efficient; (2) the developing country may be a “pollution haven”—a place to escape excessively high environmental standards in the developed country; (3) the developing country may “undercut” the developed country and attract all firms; (4) the developed country may be a pollution haven.     

Democracy,inequality and the environment when citizens can mitigate health consequences of pollution privately or act collectively

We study the political economy of the environment in autocratic, weak and strong democracies when individuals can mitigate the health consequences of domestic pollution privately as well as control pollution collectively through public policies. We consider a small open economy with comparative advantage in dirty goods. With costly private mitigation, income inequality leads to an unequal distribution of the burdens of pollution (in accordance with the evidence). We show that the eco-friendliness ranking of political regime types varies with the cost of private mitigation and that increased inequality has non-monotonous effects on equilibrium pollution levels. In weak democracies, the political equilibrium may be characterized by low environmental standards but highly restricted trade, thus leading to ambiguous outcomes regarding pollution levels.     

Trade,Strategic Environmental Policy,and Global Pollution

This paper examines the effects of international trade in a model with global pollution that accumulates over time because of production emissions in each country. If countries cooperatively determine their environmental policies, autarky and free trade in the absence of trade costs generate the same optimal solution. By contrast, if environmental policies are determined noncooperatively, the effects of trade on global pollution and welfare are ambiguous because policy games can result in multiple equilibria. Although trade increases both the lower and upper bounds of the pollution stock, whether trade expands the range of possible steady‐state pollution levels is ambiguous. The analysis then extends to consider trade costs.     

Is Corporate Environmentalism Good for Domestic Welfare?

Many private firms voluntarily care about the environment and declare that their products and production processes are environmentally friendly. This paper shows that corporate environmentalism may reduce the effectiveness of government policies. A simple third‐market trade model with strategic environmental and trade policy is employed, in which an environmentally conscious domestic firm competes with a profit‐maximizing foreign firm. It is shown that even if emission taxes and export subsidies are both available, corporate environmentalism may reduce domestic welfare when pollution is transboundary. In the realistic situation where export subsidies are prohibited, welfare may fall even if pollution is local.     

Free trade and the burden of domestic policy

Abstract. Consider a small economy facing accession to a exogenously defined trade agreement. Before accession, the government controls trade and pollution policy. After accession, it retains control over pollution policy, but must allow free trade in all goods. This is a choice many governments face while joining trade agreements today. They decide whether greater market access to other members is more valuable than control over trade policy. I ask two questions. All else being equal what happens to environmental policy after accession? Second, what affects the choice of accession and how does this choice impact aggregate welfare? I show that a loss in control over trade policy alters the political incentives determining environmental policy. Before accession, producers can transfer a portion of their burden of environmental regulation to consumers through price increases. After accession the same regulation is borne entirely by producers. Owing to the change in burden, there exist plausible conditions under which the adoption of free trade can lead to more stringent environmental regulation, a reduction in the preferential treatment of special interest groups, and an increase in aggregate welfare.     

Environmental Pollution in an Open Economy*

This paper attempts to analyze an interaction between international trade and domestic environmental pollution. A country engaging in international trade biases its domestic economic structure toward exportable sectors. The bias thus caused has a significant impact on the quality of the environment. It will be shown that a country can and should control international trade activities as a means of dealing with pollution problems. One of the paper's main purposes is to give a warning to a country which expands its international trade activities without taking serious consideration of its domestic environment.     

International treaties on trade and global pollution

The paper shows that global pollution need not rise under free trade in goods and/or emissions even in the complete absence of income effects. Differences in environmental concerns across the countries lead to differences in the pollution intensity of production and, thus, generate the possibility of increasing world output and income without increasing the world pollution by shifting the production of the polluting good from the country with higher pollution intensity of production to the country with lower one. We show that free trade in goods and/or emissions can induce precisely such a shifting of production with the country with greater environmental concern exporting the polluting good. The paper also demonstrates the possibility of a first-best international treaty on global pollution in which each country or group of countries is better-off.

环境壁垒在处理跨界污染问题中的运用

由于缺乏能够有力约束各国政府的组织存在,而各国仅从自身利益最大化来考虑污染排放,故如何让各国自愿并积极地参与环境保护协议以解决跨界污染一直是环境经济主要研究的问题之一。另外,环境壁垒一直被认为是新贸易保护主义所采取的一种贸易保护政策的新形式,其阻碍了贸易自由化的发展。然而,本文从另一角度重新审视环境壁垒,通过把它引入跨界污染博弈中形成关联博弈,最终得出环境壁垒有助于解决国家间的跨界污染问题的结论。
