Purpose - The purpose of this paper is to use the DuPont expansion to examine those factors underlying differences in (rates of) return on different crop portfolios over space (ten regions) and time (1960-2004). The paper also estimates the impact of government payments on farmland values...

This article employs the superlative Fisher and Trnqvist indexes for exact decomposition of growth in nominal revenues and costs. The findings confirm the well-known result that these indexes very closely approximate each other, implying that the mathematically simpler and computationally easier...

Allocations of research funds across programs are often made for efficiency reasons. Social science research is shown to have small, lagged but significant effects on U.S. agricultural efficiency when public agricultural R&D and extension are simultaneously taken into account. Farm management...

Fishers are faced with multiple risks, including unpredictability of future catch rates, prices and costs. While the latter are largely beyond the control of fisheries managers, effective fisheries management should reduce uncertainty about future catches. Different management instruments are...

The MODERE, the Ministry of the Environment Irrigation Decision Model, is a simulation tool whichuses mathematical programming methods to reveal the implicit multiattribute objective function lyingbehind the observed cropping decision. The model takes different criteria such as profit...

This dissertation studies the role of the collective action sector for rural development. A combination of formal modeling, historical and institutional analysis, and econometric methods is used in this research. I develop microeconomic models to analyze the determinants of peasants' decisions...

Contingent valuation (CV) is a surveying technique used to estimate the willingness to pay (WTP) by individuals for non-market goods (goods for which no market of exchange exists). Many CV studies have shown the existence of hypothetical bias which occurs when individuals are asked a...

This research examines groundwater protection programs as a case study of investments to address long-term environmental health risks. The value individuals place on reducing their risk of exposure to chemical contaminants is estimated using stated preference methodology, accounting for the...

As progress has been made on tariff reduction by recent trade agreements, barriers to freer international trade arising from nontariff sources have become more prominent. Regulation of product quality and in particular food safety can be a major source of such barriers. Lowering them requires...
