Cost-effective extension strategies are needed to promote widespread adoption of agricultural technologies in developing countries. Integrated pest management (IPM) practices, for example, can offer economic, health, and environmental benefits but remain largely underused. This study evaluates...

The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen the long run payoff to conservation tillage. Nonetheless, conservation tillage was found to be competitive with conventional tillage only if its current yield...

A dynamic programming model is developed to identify barriers to the adoption of long-run control programs for the parasitic weed Striga. The model is applied to Sirakorola in northwestern Mali. The ability of national and village-level institutions to overcome the barriers to adoption is explored.

A disaggregated variable profit function model is estiamted for French agriculture. Short-run results suggest price inelastic, positively sloped supply functions and that French agricultural production has benefited from important technological gains since the early 1960s. These gains are due...

A sizable literature on quantitative research evaluation procedures has developed, but little attent10n has been focussed on procedures for reviewing or monitoring agricultural research m an external review process. Despite their relative neglect m the literature, external reviews are...

This paper identifies direct costs and opportunity costs of bio-safety regulation for four transgenic products in the Philippines: Bt eggplant, Bt rice, ringspot-virus resistant papaya, and virus resistant tomatoes. It finds that direct regulatory costs while significant, are generally smaller...

Methods are presented for evaluating the economic benefits of agricultural economics research (AER). Decision theory and economic surplus analysis are used to evaluate returns to five representative types of AER. Benefits stem from effects of AER on economic efficiency through reduced...

With the growing competition for Federal dollars, the land grant universities were asked to justify their budget to the Congress and the Office of Management and Budget using benefitcost analysis. The authors review previous studies of returns to agricultural research and present an analysis of...

The adoption of new technologies by farmers may impact the environment, and hence affect consumer welfare. This channel of impact is seldom assessed in the literature, especially when the production technologies adopted are not labeled on the consumption goods, and as a result are not directly...
