We build a partial-equilibrium, two-country model to analyze some implications of the introduction of genetically modified (GM) products. In the model, innovators hold proprietary rights on the new technology, whereas farmers are (competitive) adopters; some consumers deem food produced from GM...

We review some of the most significant issues and results on the economic effects of genetically modified (GM) product innovation, with emphasis on the question of GM labeling and the need for costly segregation and identity preservation activities. The analysis is organized around an explicit...

Under current U.S. law, taxpayers can deduct up to 100 percent of their state income taxes from their adjusted gross income when calculating their federal income taxes. As a result, Iowans currently pay approximately $251 million less to the federal government than they would otherwise pay....

We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is...

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...

This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D)...

We employ an open economy general equilibrium model to investigate the effects of government energy policy, with emphasis on corn-based ethanol, on the U.S. economy. The model specification incorporates world and domestic markets, assumes pollution costs from fuel consumption, and allows...

We study firm reputation as a mechanism to assure product quality in perfectly competitive marketsin a context in which both certification and trademarks are available. Shapiro’s (1983) model ofreputation is extended to reflect both collective and firm-specific reputations, and this framework...
