In this paper we derive a joint continuous/censored demand system suitable for the analysis of commodity demand relationships using panel data. Unobserved heterogeneity is controlled for using a correlated random effects specification and a Generalized Method of Moments framework used to...

Do healthier diets cost more? We estimate a hedonic regression model of the U.S. diet. Given food expenditures and information on dietary intake we infer the marginal cost of improved quality. MeetingthePyramidrecommendationsimpliesdecreasedexpendituresfromtwoofthe seven food groups.

Examines linkages between food and health spending patterns, income, and health status of the elderly. Links these relationships to food insecurity and expenditures on nutraceuticals. Methodology includes simultaneous estimation of expenditure systems and health production functions. Preliminary...

Our overarching goal is to understand critical determinants of low-income elderly Americans’ well being as measured by health status. We focus on whether and how elderly health status is affected by FSP participation, food sufficiency and other determinants. To do so we must first ascertain...

This paper uses nationally representative data to describe a monthly cycle in food expenditure and food intake by food stamp recipients. Food expenditure peaks sharply in the fIrst three days after food stamps are received. Actual food intake drops at the end of the month, for some foods and...

A pollution reduction program is designed where information about both techno logy and risk preferences is asymmetric. Program costs and the distribution of payments depend on the amount of information known to the policy maker. Empirically testable conditions for selfselection are derived; the...

Since many countries already pursue a range of environmental objectives for agriculture, in particular the supply of positive externalities or public goods (e.g., wildlife habitat, water supply management, provision of landscape amenities) as well as the reduction of negative externalities, such...

Major sources of variability in net farm income on New York dairy farms over the past 10 years are identified using variance decomposition methods. The most important source of income variability is the fluctuation in milk prices, followed closely by year-to-year variation in the quantity of...

The purpose of this study is to understand the implications of farm-to-farm and regional variations in nitrogen runoff and leaching for targeting specific policies to reduce nutrient contamination. To do this, we estimate 3D-year distributions of nitrate runoff and leaching for individual soils...

We re-examine the notion of consumer rationality in transition economies by modifying the conventional non-parametric tests of the axioms of revealed preference. To reflect the unique characteristics of transition economies, shortages are allowed in the state market, while not in the private...
