Using farm-level data from the 1987, 1992, and 1997 Census of Agriculture, this study estimates what effect agricultural payments have had on the likelihood of farm business survival and on farm size. The unique panel data set permits conditioning current farm size on past farm size, which removes much of the individual heterogeneity of farms that could be spuriously correlated with payment levels. Results indicate that between consecutive censuses, past per acre payments have a significant positive effect on farm business survival and a small yet significant influence on the size of continuing farms.

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.
