A wide variety of multilateral and bilateral agencies, private sector firms, and African governments have a need for high quality, reliable data on agricultural productivity. This paper identifies numerous situations where poor data lead to incorrect estimates of African land and labor...

Senegal has experienced a number of spurts in agricultural production and productivity growth since independence, yet average trends from 1960 through 1993 have been either stagnant (in terms of aggregate production and yields), or negative (in terms of real value of production). Although use of...

One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets....

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...

The purpose of this paper is to provide a conceptual framework that can be used by agricultural leaders, administrators, policy makers, and seed program managers to (1) understand key factors affecting seed system development; and (2) compare organizational and institutional strategies for...

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...

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...

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...

This paper uses a profit function theoretical approach and three stage least squares regression analysis for examining the relationship between land-intensifying technologies and deforestation in the Peruvian Amazon. This modeling approach permits analysis of the determinants of input technology...
