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...

This article analyzes the primary activities of agricultural college faculty with and without extension appointments using survey data. The evidence suggests that differences between extension professors and others in agricultural colleges in terms of research production are small for minor...

This article exploits panel data from Wisconsin dairy farmers to examine the dynamics of recombinant bovine somatotropin (rBST) adoption and to identify the characteristics that distinguish among nonadopters, disadopters, and early and late adopters. Panel methods are used to control for omitted...

This work analyzes the evolution of time allocation for agricultural and life science faculty in Tier 1 US research universities from 1975 to 2005. Specifically, it explores the trends with respect to time spent on research versus administrative activities, and shows about a 20% decline in the...

This paper examines the factors that account for ag-biotech patenting success among universities using a dynamic count data model. It builds a theoretical and econometric model to capture the inherently dynamic and nonlinear process of technological innovation, wherein a feedback mechanism from...

Trends and determinants in the adoption of recombinant bovine somatotropin are examined using data from across the United States. The core findings are: (a) moderate adoption rates and relatively small impacts on national milk production; (b) substantial disadoption, farmers who have tried the...

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...

Major legislative, legal, and technological changes paved the way for a period of remarkable growth in the patenting of life science research by U.S. universities in the 1980s and 1990s. Using a multiple-output cost framework and two decades of panel data on ninety-six universities, this article...

Trends and determinants in the adoption of recombinant bovine somatotropin are examined using data from across the United States. The core findings are: (a) moderate adoption rates and relatively small impacts on national milk production; (b) substantial disadoption, farmers who have tried the...
