The United States is a large net exporter of corn seeds. Seed trade, including corn, has been expanding but its determinants are not well understood. This paper econometrically investigates the determinants of world demand for U.S. corn seeds with a detailed analysis of trade costs impeding...

The following paper outlines a new econometric model designed to capture both the temporal and spatial dynamics of housing prices. The paper combines existing spatial econometric techniques with a model that allows parameters to evolve over time. In addition, we provide an empirical application...

The welfare effects of GM (genetic modification)-led productivity growth for cassava producers are partly affected by the characteristics of individual cassava producing households. Those household characteristics include the elasticity of production and home consumption of cassava. Some studies...

This study determines how production and trade policy distortions affected rice productivity in thirty-three rice-producing countries. A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for...

Biomass yield to nitrogen response functions were determined for four perennial grass species. The species, nitrogen level, and harvest frequency that maximize expected net returns given the climate and soils of the U.S. Southern Plains were determined. For most combinations of biomass and...

This paper assesses the potential for function based benefit transfer to inform farmland preservation policy, with emphasis on distinctions between welfare estimation and policy prioritization. Data are drawn from a parallel choice experiments implemented in six communities and statewide in...

According to Ricardian rent theory, the value of farm assets is equal to the discounted present value of future expected net rents from farm returns, and the discounted expected value of the land if converted to nonfarm development. Some recent research has considered modifying this standard...

This paper develops a model of optimal allocation of GM and non-GM crops under contamination risk. The model is used to compare the producer optimal crop allocation at equilibrium to the social efficient crop allocation. From the socially optimum conditions, the paper identifies production...
