| Genetic modification of crops has revolutionized food production, but it remains controversial due to food safety and environmental concerns. A recent food safety scare provides a natural experiment on the corn market's willingness to accept unapproved genetically modified organisms. In 2000, a genetically modified corn variety called StarLink was discovered in the food-corn supply, even though it was not approved for human consumption. To estimate the price impact of this event, we develop the relative price of a substitute method, which applies not only to the StarLink event but also to rare events in other markets. We apply this method to measure the price impact of the StarLink contamination on the U.S. corn market. We find that the contamination led... |

| The study finds that the emergence and expansion of the ethanol sector was associated with a fundamental transformation of the integration of the energy and agricultural sectors. In particular, the correlation structure between crude oil and grain prices increased dramatically, becoming more statistically significant, and with all anomalous signs corrected. Before the ethanol boom, the correlation of the crude oil price and corn was -0.117. It increased to 0.876 in the ethanol boom period. Soymeal correlation increased from 0.182 to 0.909, and distillers dried grains with solubles increased from -0.252 to 0.834. As a result, the energy market is also now impacting the livestock sector through feed costs, which account for more than half of total costs.... |

| Changes to commodity programs in the 2002 Farm Bill increased the value of crop base acreages on which decoupled payments are received. The bill also expanded the availability of key conservation programs. This paper compares the value of payments from commodity programs (along with continued crop production) to the easement payment (and recreational lease revenue) available under the Wetland Reserve Program. A net present value model using risk-adjusted returns is employed in the analysis for Mississippi delta cropland containing rice, cotton, and soybean base. Sensitivity analysis is conducted on some of the key variables affecting the decision. |

| We analyze the impact of trade liberalization and removal of the federal tax credit in the United States on U.S. and Brazilian ethanol markets using a multi-market international ethanol model calibrated on 2005 market data and policies. The removal of trade distortions induces a 23.9 percent increase in the price of world ethanol on average between 2006 and 2015 relative to the baseline. The U.S. domestic ethanol price decreases by 13.6 percent, which results in a 7.2 percent decline in production and a 3.8 percent increase in consumption. The lower domestic price leads to a 3.7 percent rise in the share of fuel ethanol in gasoline consumption. U.S. net ethanol imports increase by 199 percent. Brazil responds to the higher world ethanol price by increasing... |

| Throughout recent year food quality standards have become a ubiquitous phenomenon that nationally and globally influences agri-food markets. With equilibrium models commonly used in the quantitative analysis of market and trade effects, we review possible approaches to modeling standards existent in the literature, elaborate the reasoning behind them and discuss their suitability to reflect "real world" situations. While the modeling approaches identified may respectively depict a specific situation, they may not be appropriate in others. That is they capture certain effects of standards only. With increasing ability to account for the various effects of standards, the modeling approaches become more complex and the data requirements increase. |

| As evidenced by the recent release of a comprehensive Institute of Medicine report on seafood consumption and by the passage of the 2002 Farm Bill, it is clear that there is growing concern about the health benefits and risks of fish consumption. This research project was designed to analyze the seafood market in Amherst, Massachusetts, and, specifically, to explore the effectiveness of seafood product labeling provided by the largest retailers in the area. Studying the availability of seafood and the associated labeling practices reveals how the Amherst market meets the needs of different consumers. While each venue generally adheres to the regulatory requirements of seafood labeling, this research includes recommendations as to how the market might... |

| This article examines the effects of the application of panel data estimation methods on a system of equations with unbalanced panel data. We apply pooled, random-effects, and fixed-effects estimation in three data sets: small, medium, and large farms to examine the relationship between farm size and the elasticity of cotton supply with respect to cotton price. Our results indicate that the adoption of various estimation methods entails different estimated parameters both in terms of their absolute value and in terms of their statistical significance. Additionally, the elasticity of cotton supply with respect to price varies according to farm size. |
