This paper uses data from dairy farmers in six U.S. states to examine farm-level factors influencing the adoption of recombinant bovine somatatropin (rBST), a productivity-enhancing hormone that is injected in cows. The results of multinomial logit estimations of rBST adoption and disadoption...

This paper explores the dynamics of rBST adoption using panel data from Wisconsin dairy farmers that span the period from its commercial introduction in 1994 to 2001. The panel data allow an examination of a broader range of adoption behavior that includes disadoption, early and late adoption,...

This work exploits information on U.S. patents to identify trends in university ag-biotech patenting and citation performance. It sets forth some key issues concerning patterns of university ag-biotech patenting and then provides an empirical analysis on the evolving trends. Land Grant...

GM corn seed companies have innovated continuously with the introduction of new traits and, more recently, with the creation of stacked varieties, which combine more than one trait. This work develops a Bayesian model of adoption dynamics that demonstrates how uncertainty with a package...

We used a state contingent approach to give a detailed analysis of the uncertainty surrounding seed trait adoption. Our framework emphasizes the role of timing and information in farmers’ adoption decisions. The inherent embeddedness of seed traits results in timing restrictions and the...

This paper examines the empirical evidence for synergies or tradeoffs associated with the rapid rise of ag-biotech patenting at Land Grant Universities by examining the question of whether journal articles and patents appear to be complementary or competing activities in agricultural...

This work offers a new approach to the adoption of GM crop varieties by adopting the econometric methodology of the characteristics-based demand literature. A random utility framework was implemented through different specifications of a conditional (CL) and a mixed multinomial logit (MMNL)...

This paper investigates the presence and sources of economies of scope in R&D production at U.S. research universities. The analysis evaluates the tradeoffs or synergies arising between traditional university research outputs (articles and doctorates) and a more recent and burgeoning output:...

This work uses non-parametric efficiency analysis and a unique panel data set to analyze efficiency and technical change at US universities from 1981-1998 with a special emphasis on Land Grant institutions. The analysis demonstrates that Land Grants are on average more efficient than their...
