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...

Several characteristics of biotech industry structure follow cyclical patterns. Mergers and acquisitions activity shows cyclical behavior, with peaks from 1988-92 and 1996-97 and a valley from 1993-95. The ratio of large-firm to small-firm field trials, and the Herfindahl-Hirshmann concentration...

The nature of public agricultural research changed in 1980 when the Bayh-Dole Act allowed universities to retain title to inventions that were created with Federal funds, and the court case Diamond v. Chakrabarty allowed patenting of living tissue and eventually other bio-engineered products. In...

This paper examines the impact of European Union policy on genetically modified organisms on trade flows and economic growth. Restrictive European Union policies on biotech production and consumption result in: an effective export subsidy of capital to the South; new trade flows; North America...

As dairy farms grow and specialize in milking cows, one enterprise that may be removed from the dairy farm to allow for milk cow herd expansion is heifer raising. Custom heifer raising is increasingly common across the country and purchasing heifers may be preferred to raising heifers. However,...

Milk sales are the largest source of revenue on dairy farms. Reproduction is necessary to generate a new lactation. However, a pregnancy also dictates when the previous lactation must end so that the cow can retain sufficient condition into her new lactation. Pregnancy rate and estrus detection...

This report summarizes the financial and production records of 11 dairy grazing farms from across Michigan. These 11 farms indicated that they grazed dairy cows at least three months of the year and that grazing provided more than 30 percent of the forage consumed during the year. To be...

This report summarizes the financial and production records of 23 dairy farms across the Upper Peninsula (UP) of Michigan. To be included, the farms must have produced at least 50 percent of gross cash farm income from milk and dairy animal sales. The farms in this report were located throughout...
