Toxic chemical releases, health effects, and productivity losses in the United States.

In this paper we examine the impacts of toxic chemical releases on labor productivity. The hypothesis is that exposure to releases results in chronic or acute illnesses, which increases number of work days lost. To test the hypothesis we combine data from the National Health Interview Survey with data from US Environmental Protection Agency's Toxic Release Inventory, using an instrumental variable approach to control for endogeneity of subjective binary health status.

Assessment of economic and water quality impacts of land use change using a simple bioeconomic model.

The objective of this study is to assess the economic and water quality impact of land use change in a small watershed in the Wiregrass region of Alabama. The study compares changes in water quality and revenue from agricultural and timber production due to changes in land use between years 1992 and 2001. The study was completed in two stages.

Environmental regulation through trade: the case of shrimp.

The implications of a potential ban on shrimp imports by the US from countries that do not utilize the Turtle Excluder Device on commercial shrimp nets is explored in this paper. A Linear Expenditure System (LES) was used to determine the own-price elasticities of demand for shrimp imports. The system of estimated equations was then solved for quantity levels under assumptions made about the trade restrictions, resulting in a set of prices for those import levels.
