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...

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...

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,...

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...

Finisher hog production in North America has shifted toward larger units and contract format since 1990. Exit among independent growers has been high. We develop a model showing that growers with any of three efficiency attributes (lower innate hazard of exit, variable costs, or contract...
