This paper develops a spatial equilibrium model suitable to analyze the economic impacts of measures (such as isolation distances and buffer zones) meant to ensure coexistence between GM and non-GM crops. We show that policies that put the cost of such measures exclusively on GM producers lead...

Many decisions in agriculture are made over combinations of inputs and/or practices that may be complements. The presence of complementarity among producer decisions can have deep implications for market outcomes and for the effectiveness of policies intended to influence them. Identifying...

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)...

The economics of geographical indications (GIs) is assessed within a vertical product differentiation framework that is consistent with the competitive structure of the agricultural sector with free entry/exit. It is assumed that certification costs are needed for GIs to serve as (collective)...

The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are...

This paper considers the conversion of import quotas into tariffs, as may arise in the current round of General Agreement on Tariffs and Trade (GATT) negotiations, when the internal market of the country imposing the quota is not perfectly competitive. This case is illustrated by the chicken...

The United States is a large net exporter of corn seeds. Seed trade, including that of 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...

In this article, the author reviews intellectual property rights (IPRs), with some emphasis on the protection of agricultural and life sciences innovations. The main institutional features of IPRs are first discussed, along with a brief historical background and an articulation of the main...

In line with the rights and incentives provided by the Bayh-Dole Act of 1980, U.S. universities have increased their involvement in patenting and licensing activities through their own technology transfer offices. Only a few U.S. universities are obtaining large returns, however, whereas others...

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...
