Liberalizing trade in environmental goods and services

We examine the effects of trade liberalization in environmental goods in a model with one domestic downstream polluting firm and two upstream firms (one domestic, one foreign). The upstream firms offer their technologies to the downstream firm at a flat fee. The domestic government sets the emission tax rate after the outcome of R&D is known. The effect of liberalization on the domestic upstream firm's R&D incentive is ambiguous. Liberalization usually results in cleaner production, which allows the country to reach higher welfare. However this increase in welfare is typically achieved at the expense of the environment (a backfire effect)

Environmental Protection for Sale: Strategic Green Industrial Policy and Climate Finance

Industrial policy has long been criticized as subject to protectionist interests; accordingly, subsidies to domestic producers face disciplines under World Trade Organization agreements, without exceptions for environmental purposes. Now green industrial policy is gaining popularity as governments search for low-carbon solutions that also provide jobs at home. The strategic trade literature has largely ignored the issue of market failures related to green goods. I consider the market for a new environmental good (like low-carbon technology) whose downstream consumption provides external benefits (like reduced emissions). Governments may have some preference for supporting domestic production, such as by interest-group lobbying, introducing a political distortion in their objective function. I examine the national incentives and global rationales for offering production (upstream) and deployment (downstream) subsidies in producer countries, allowing that some of the downstream market may lie in nonregulating third-party countries. Restraints on upstream subsidies erode global welfare when environmental externalities are large enough relative to political distortions. Climate finance is an effective alternative if political distortions are large and governments do not undervalue carbon costs. Numerical simulations of the case of renewable energy indicate that a modest social cost of carbon can imply benefits from allowing upstream subsidies

Strategic Subsidies for Green Goods

Globally and locally, government support policies for green goods (like renewable energy) are much more popular internationally than raising the cost of bads (as through carbon taxes). These support policies may encourage downstream consumption (renewable energy deployment) or upstream development and manufacturing of those technologies. The use of subsidies—particularly upstream ones—is disciplined by World Trade Organization agreements, and its subsidies code lacks exceptions for transboundary externalities like human health or resource conservation, including those related to combating global climate change. The strategic trade literature has devoted little attention to the range of market failures related to green goods. This paper considers the market for a new environmental good that when consumed downstream may provide external benefits like reduced emissions. The technology is traded internationally but provided by a limited set of upstream suppliers that may operate in imperfect markets, such as with market power or external scale economies. We examine the national incentives and global rationales for offering production and consumption subsidies in producer countries, allowing that some of the downstream market may lie in nonregulating third-party countries. Although technology producer countries can benefit from restraints on upstream subsidies, global welfare is higher without them, and market failures imply that optimal subsidies are even higher. We supplement the analysis with numerical simulations of the case of renewable energy, exploring optimal subsidies for the major renewable energy producing and consuming regions and the cost of restrictions on upstream subsidies
