Over the past twenty years, the R&D-based agricultural biotechnology industry has exhibited cyclical behavior in consolidation. This paper provides a positive, theoretical model of endogenous R&D, in which the number of firms engaged in R&D exhibits cyclical behavior. Additional, empirically...

The nature of the observed market structure and R&D competition in genomics research is used as the basis for a comparative analysis of research under a mixed oligopoly, pure oligopoly and monopoly when the timing of the innovation outcome is uncertain (as in an R&D race), the winner-take-all...

Despite the clear influence of European Union biotechnology restrictions on trade patterns, very little work has been done to model these influences or their long-run effects. This paper presents an economic trade theory model of biotechnology, biotechnology research and development (R&D), and...
