Agricultural tillage practices are important human-induced activities that can alter carbon emissions from agricultural soils and have the potential to significantly contribute to reductions in greenhouse gas emission. This paper investigates the expected costs of sequestering carbon in...

There is a growing need for research that estimates the potential value to farmers of acquiring and using improved information about spatial variability within their fields. This paper considers the potential value of switching from single rate technologies (SRT) to variable rate technologies...

Develops a framework for incorporating estimation risk into a decision model to determine the optimal amount of soil test information when applying nitrogen fertilizer using a variable rate technology (VRT). Producers should acknowledge that the soil nitrate mapping is a collection of estimates...

Soil sampling has long been advocated as a means of improving the efficiency of fertility management decisions by better matching fertilizer applications with crop nutrient requirements and nutrient availability. Advances in mapping and sensing technologies have renewed interest in soil sampling...

This study analyzes the effects of liberalization barriers to trade for six U.S. specialty crops: fresh grapes, fresh oranges, fresh grapefruits, peanuts, potatoes and almonds. The total value of Unites States exports of each commodity to the world and to the major four or five importers is...

In an earlier work [Zusman and Rausser (1990a)], we expounded a descriptive integrated theory of a political-economy. As is generally the case, the motivations for developing the theory were: (a) to provide a general explanation of the working of a political-economy and (b) to provide a...

What agricultural opportunities may be opened to countries such as Egypt due to the liberalization of world trade? This paper discusses the effects of changes in market access, domestic support, and export competition outlined in the recent General Agreement on Tariffs and Trade (GATT), and...

Endogenizing the exchange rat in trade models over the period of fixed and flexible exchange rate systems poses an econometric problem in the estimation because of the fixity of the exchange rate under the fixed exchange rate system. An econometric technique, the grafted polynomial approach, is...

Given the empirically observed sensitivity of welfare estimates to functional form, it is natural to consider whether nonparametric methods such as those developed by Varian might be of value in nonmarket welfare analysis. This study presents simple methods for constructing nonparametric bounds...

The objective of this study was twofold: (1) to identify nontraditional sources of data that can be used to monitor economic activity in rural areas, and (2) to test the relationship between such data and trends in traditional measures, such as income and employment.
