| Public health experts are concerned about the diminishing efficacy of antibiotics. Some have called for a ban on growth-promoting antibiotics in animal agriculture. This study identifies the contribution of growth-promoting antibiotics in the grower/finisher phase of U.S. pork production. With National Animal Health Monitoring System swine data, relationships are estimated between growth-promoting antibiotic use and productivity. Results indicate improvements in average daily gain (0.5%), feed conversion ratio (1.1%), and mortality rate (reduced 0.22 percentage points); these productivity improvements translate into a profitability gain of $0.59 per pig marketed, or an improvement of 9% in net profits associated with growth promotion antibiotics. |

| Produce growers in Kentucky, North Carolina, and Tennessee were surveyed in 2002 to gather information about their decision making in the areas of planting, postharvest handling, marketing, and expected changes. North Carolina has proportionately more respondents with large operations, and Kentucky and Tennessee were more similar and concentrated in smaller farms. Tennessee and Kentucky respondents were less likely to have engaged in activities that were associated with the commercial distribution system. Greater reliance on the commercial distribution system on the part of North Carolina growers is consistent with more produce export activity. |

| This paper develops an analytical model able to represent the decisions of an individual risk averse farmer facing variability in both prices and yields. A comprehensive set of stylised risk reducing policy measures is represented. A calibration of the model is used to run Monte-Carlo simulations and to obtain optimal responses. The main focus is the interaction between policy measures and market strategies in terms of impacts on production, welfare and risk. Risk reducing strategies that cover different sources of risk, such as price and yield variability, may be complementary for the farmers. Counter-cyclical area payments create incentives to bring land into production and their capacity to reduce farming risk is mitigated by the potential crowding out... |

| We use data from a recent national survey to analyze the use of subtherapeutic antibiotics (STAs) among producers of broilers. STAs are included in feed or water and are intended to prevent disease or promote growth. Producers who do not use STAs instead rely on a set of other practices, including pathogen testing, expanded sanitary protocols, altered feeding regimens, and HACCP plans, to maintain production. We find that producers who do not use STAs realize levels of production that are slightly lower, given other inputs, than STA users, but the differences are not statistically significant. STA users realize lower payments per pound than those who are not users. The 4 percent difference, which is statistically significant, suggests that STA users have... |
