This essay revisits the question of instrument choice for the regulation of externalities in the context of climate change. The central point is that the Pigouvian prescription to equate marginal control costs with the expected marginal benefits of damage reduction should guide the design of...

Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of India's environmental regulations. The air pollution regulations were effective at reducing...

We study the determinants of comparative advantage in polluting industries. We combine data on environmental policy at the country level with data on pollution intensity at the industry level to show that countries with laxer environmental regulation have a comparative advantage in polluting...

China's extremely high levels of urban air, water and greenhouse gas emissions levels pose local and global environmental challenges. China's urban leaders have substantial influence and discretion over the evolution of economic activity that generates such externalities. This paper examines the...

Public policies for pollution control, including climate change policies, sometimes allow polluters in one sector subject to an emissions cap to offset excessive emissions in that sector with pollution abatement in another sector. The government may often find it more costly to verify offset...

This paper develops a simple model of a polluting industry and an innovating firm. The polluting industry is faced with regulation and costly abatement. Regulation may be taxes or marketable permits. The innovating firm invests in R&D and develops technologies which reduce the cost of pollution...

Governments support particular firms or sectors by granting low interest financing, reduced regulation, tax relief, price supports, monopoly rights, and a variety of other subsidies. Previous work in partial equilibrium shows that subsidies to environmentally sensitive industries increases...

In our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production, we study the effects of a tax on one pollutant in two cases: one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy. In...

China's environmental regulators have sought to reduce the Yangtze River's water pollution. We document that this regulatory effort has had two unintended consequences. First, the regulation's spatial differential stringency has displaced economic activity upstream. As polluting activity...

Fears that globalization necessarily hurts the environment are not well-founded. A survey reveals little statistical evidence, on average across countries, that openness to international trade undermines national attempts at environmental regulation through a race to the bottom' effect. If...
