A partial equilibrium four-region world trade model for the soybean complex is developed in which Roundup Ready (RR) products are weakly inferior substitutes to conventional ones, RR seeds are priced at a premium, and costly segregation is necessary to separate conventional and biotech products....

We relate the labeling of genetically modified (GM) products to the theory of grading and minimum quality standards. The model represents three stages in the supply chain, assumes a vertical product differentiation framework, allows for the accidental commingling of non-GM products, and treats...

An open-economy equilibrium model is derived to investigate the effects of energy policy on the U.S. economy, with emphasis on corn-based ethanol. A second best policy of a fuel tax and ethanol subsidy is found to approximate fairly closely the welfare gains associated with the first best policy...

We review intellectual property rights in agriculture and outline a modeling framework that accounts for relevant institutional features of agricultural R&D. The analysis emphasizes vertical market linkages whereby agricultural innovations adopted by farmers are produced upstream by input...

This paper analyzes the role of the initial payment used by the Canadian Wheat Board (CWB) in the determination of export prices and sales under the assumption that the CWB has better information about realized yields in Canada than its US competitor. In the separating equilibrium of the game,...

A partial-equilibrium, two-country model is developed to analyze implications from the introduction of genetically modified (GM) products. In the model, innovators hold proprietary rights, farmers are (competitive) adopters, some consumers deem GM food to be inferior in quality to traditional...

This article investigates the policy active importers' incentives and welfare implications of using production and trade policies in a dynamic framework where production decisions occur before consumption decisions. We show that the equilibrium for production taxes and quotas are not equivalent,...
