Over the past fifteen years, the agricultural biotechnology industry has exhibited cyclical behavior in concentration and consolidation. This paper provides a theoretical model of endogenous R&D, in which industry concentration exhibits cyclical behavior. The model also generates additional...

The emergence of agricultural biotechnology and policy responses to is altering global agricultural trade patterns. This paper models the effects of restrictive policies concerning the production and consumption of genetically modified agricultural products. The model relies on a...

Electronic food retailers can satisfy their customers more effectively if they understand how this particular market works. As in other service segments, the emergence of electronic business-to-customer services in the retail food industry poses questions for managers about the design of new...

Investments over the past 35 years have created a system of national and international research centers that has revolutionized the supply of improved cereal varieties to developing country farmers. The newly created scientific ability to exploit genetic resources has been the engine of...

We discuss how to measure allocative efficiency without presuming technical efficiency. This is relevant when it is easier to introduce reallocations than improvements of technical efficiency. We compare the approach to the traditional one of assuming technical efficiency before measuring...

A dynamic farm production model analyzes the interaction between the externalities caused by pest mobility and the development of pesticide resistance, a nonrenewable resource, in the context of agricultural biotechnologies. The model measures the effect of farmers' myopic behavior and the...

The decision to replant a fire blight-susceptible apple orchard is analyzed. Embedding the problem into an equilibrium framework facilitates the welfare analysis of changes in orchard survival probabilities arising from a ban on antibiotics use. We estimate the structural impacts and welfare...

Farmers now choose production systems rather than individual inputs. This change may limit biotechnology innovation rents. We model a corn farmer's production choice among four systems: traditional, herbicide-resistant, insect resistant, and high-oil. We compare actual seed and chemical prices...

We examine the impact of intellectual property rights (IPRs) on US exports of biological, medicinal, botanical, and pharmaceutical products. We find that: (1) strong IPRs enhance monopoly power of US exports in countries with weak imitative abilities; and (2) strong IPRs expand markets for US...
