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...

The introduction of the U.S. SO2 allowance-trading program to address the threat of acid rain as part of the Clean Air Act Amendments of 1990 is a landmark event in the history of environmental regulation. The program was a great success by almost all measures. This paper, which draws upon a...

Intertemporal tradability allows an emissions market to reduce abatement costs. We study intertemporal trading of nitrogen oxides permits in the RECLAIM program in Southern California. A theoretical model captures the program's key intertemporal features: two overlapping permit cycles, two...

This study quantifies the cost savings from the Acid Rain Program (ARP) compared with a command-and-control alternative and also examines the impact of trading under the ARP on health damages. To quantify cost savings, we compare compliance costs for non-NSPS (New Source Performance Standards)...

Title IV of the Clean Air Act Amendments of 1990 created a market for electric utility emissions of sulfur dioxide (SO2). Recent papers have argued that flaws in the design of the auctions that are part of this market have adversely affected its performance. These papers incorrectly assume that...

We conduct the first study on the impacts of prenatal exposure to a uniquely identified large polluter, a coal-fired power plant located near the border of two states, on the birth outcomes of the downwind state. For mothers who live as far as 20 to 40 miles away but downwind of the power plant,...

Electric utilities can reduce sulfur dioxide emissions through a variety of strategies such as adding scrubbers, switching to low- sulfur coal, or shifting output between generating plants with different emissions. The cost of achieving a given emission target can be minimized using a market for...

A sizeable number of papers beginning with Roberts and Spence (1976) have studied the use of price floors and ceilings (or "collars") to manage prices in tradable permit markets. In contrast, economists have only recently begun examining polices to manage quantities under a pollution tax....

Willingness to pay for air quality is a function of health and the costly defensive investments that contribute to health, but there is little research assessing the empirical importance of defensive investments. The setting for this paper is a large US emissions cap and trade market - the NOx...

Cap and trade programs have considerable heterogeneity in permit validity and compliance timing. For example, permits have different validity across time (e.g., banking, borrowing, and seasons) and space (e.g., zonal restrictions), and compliance timing can be annual, in overlapping cycles, or...
