This paper formulates and estimates a structural intertemporal model of a woman’s household participating in the Supplemental Nutrition Assistance Program (SNAP) and her likelihood of being obese. We use an economic model of lifetime behavior in a finite life model to provide the structure of...

In many countries, including those in the European Union, Japan, Australia, and China, labeling is required for foods that contain genetically modified material. Other countries, including the United States, do not require mandatory labeling of GM foods. The United States, however, does allow...

Many countries require labeling for GM food products. These countries often have different levels of genetic modification that they will tolerate before a food product must be labeled as genetically modified. For example, the European Union and Australia allow up to one percent of any ingredient...

The paper presents econometric evidence on off-farm work participation, off-farm hours of work, and on-farm hours of work for U.S. farm operators using a national sample of farmers for the USDA's 1991 Farm Costs and Return Survey.

This study uses new state data to examine the contributions of public agricultural research, extension, and infrastructure to agricultural productivity. The estimated social rates of return (which take into account spillover effects) are high and imply a need for federal or regional institutions...

This paper examines women’s and men’s decisions to participate in physical activity and to attain a healthy weight. These outcomes are hypothesized to be related to prices of food, drink and health care services and products, the respondent’s personal characteristics (such as education,...

Most studies utilizing experimental auction mechanisms to elicit consumers’ willingness to pay are designed to avoid potential substitution or demand-curve effects that may influence bid prices. However, previous research and auction designs have not considered the potential impact on bid...

Replaced with revised version of paper 07/22/08.

Our paper begins with a consideration of the causal relationships among productivity, farm structure, government farm payments and public investments in research and extension. We then empirically test key relationships for a relatively recent period (1960-96) in the history of agricultural...

The paper analyzes the decision-making of rural Chinese households with three alternatives: stay exclusively on farm, take local off-farm jobs, and migrate. Based on a survey of rural Chinese households, we extend the dynamic discrete choice model of Wooldridge (2002a,b) to a trichotomous...
