Since 2000, approximately $50 million per year has been spent to control infestations of the Glassy-Winged Sharpshooter (GWSS), an insect that spreads Pierce’s Disease (PD). This amount includes the costs of state and federal efforts to monitor and control the GWSS, research on PD/GWSS, and compliance with the PD Control Program. Using a simulation model of the market for California wine grapes, we estimate that under the current program, PD costs winegrape growers and consumers $92 million annually. If the program ended and the GWSS became widespread throughout California, the annual cost borne by growers and consumers would increase by an estimated $185 million.

This paper considers the economic and environmental implications of regulating water and air nitrogen emissions under single and multi-environmental media policies in the U.S. hog industry. We examine tradeoffs from policies designed to correct an externality in one medium, when there are multiple environmental externalities. We separately and jointly analyze: (a) nitrogen land application restrictions consistent with recently adopted EPA requirements under the Clean Water Act, and (b) hypothetical air quality restrictions under the Clean Air Act, both with and without EQIP payments available to mitigate the costs of complying with nutrient application regulations.
