We analyze the effects of the North American Free Trade Agreement (NAFTA) and United States farm subsidies on U.S.-Mexican illegal immigration and agricultural trade. The theoretical analysis develops an integrated trade-migration model and shows that NAFTA and U.S. subsidies exacerbate the illegal labor flow and increase U.S. exports. The theoretical analysis is empirically implemented by simultaneous estimation and simulation analysis. The analysis shows that NAFTA increased the number of undocumented workers to U.S. agriculture and U.S. farm exports to Mexico by an average of 1573 and $6.82 billion, respectively. U.S. farm subsidy reduction decreases unauthorized entry marginally and U.S. farm exports by an average of $3.2 billion.

Coffee consumption in China has seen a significant rise in recent years. This study seeks to explore the determinants of coffee consumption in China with a specific focus on fair trade coffee. In a survey of 564 respondents in Wuhan City, consumers' willingness to pay (WTP) for fair trade labeled coffee was measured. This study uses an interval regression to investigate individual demographic and consumption characteristic impacts on WTP. Results show that on average, consumers were willing to pay 22% more for a medium cup of fair trade coffee compared with traditional coffee. In addition, other variables that indicated a higher WTP included female consumers, consumers who made their own coffee, and consumers who planned to consume more coffee in the following year.

Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations. We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE's capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

The economic impact of wildlife-associated recreation in the Southeast United States was evaluated using a general equilibrium model. Exogenous demand shocks to the regional economy were based on estimates of expenditures by wildlife recreationists on hunting, fishing, and wildlife watching activities. Counterfactual simulations were carried out, making alternative assumptions about labor and capital mobility and their supply. Without wildlife-associated recreation expenditures, regional employment would have been smaller by up to 783 thousand jobs, and value added would have been $22 to $48 billion less. These findings underscore the significance of regional factor market conditions in economic impact and general equilibrium analysis.

We utilize a treatment effects model to examine if there are differences in costs/profits for manure-using corn producers versus non-users. We find that manure users have lower peracre operating costs via reductions in fertilizer and soil conditioner costs; however, the use of manure reduces grain yields and ultimately leads to no difference in profit. Separate results indicate that manure-use restrictions do not affect costs or profits; thus policies could be in place to regulate manure usage without impacting the costs/profit structure of the farm.

The inclusion of cover crops in cropping systems brings direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management. Results may help in understanding factors shaping farmers' perceptions, adoption, and retention of cover crops.

This article examines the impact of Bt corn adoption in the Philippines using an econometric approach that addresses simultaneity, selection, and censoring problems. Although previous literature emphasizes the importance of simultaneity and selection problems, this is the first study that addresses the issue of censoring in estimating the effects of Bt corn adoption at the farm in a developing country context. We show that Bt corn adoption provides modest but statistically significant increases in farm yields and profits. Furthermore, our results provide some evidence of inference errors that can potentially arise when censoring in the pesticide application variable is ignored in the estimation procedures.
