Econometric studies of the effects of research on productivity have typically imposed arbitrary restrictions on the length and shape of the R&D on productivity and the estimated rate of return to research. This paper argues that the useful stock of public knowledge depreciates, if at all, only...

Traditional measures of the benefits of technological change use producer prices. Consumer-oriented measures are more appropriate but they require knowledge of price impacts. They may diverge in the presence of distortions. This paper shows that in general equilibrium they are interrelated...

We investigate the temporal and spacial nature of productivity growth and its components in Chinese agriculture from 1980-1995 using nonparametric Malmquist procedures. The results indicate that the high rate of technical progress and deterioring efficiency performance coexisted in Chinese...

There is a growing body of literature on the safe use of biotechnology and the need for an international biosafety protocol and national regulations to facilitate the safe development and transfer of biotechnology. Most of these studies, however, address the issue of biosafety from a scientific,...

This case study aims to analyze the impact of the most important agro-techniques, i.e., land leveling, field bunding, gypsum application and the sprinkler method of irrigation on the performance of pearl millet-wheat and pearl millet-mustard cropping systems with saline/alkaline water irrigation...

The controversial introduction of rbST, a laboratory version of bST, a growth hormone that stimulates milk production in cows, may provide hopeful lessons for other foods produced by biotechnology. Milk sales remained steady after rbST became available to dairy farmers, even though a multitude...

These papers move beyond the questions of who adopts technologies to ask how preferences for characteristics (of maize in Mexico or cattle in Burkina Faso) affect adoption and how technical change differentially affects semi-subsistence farmers and how it affects productivity and yield...

A digitally represented watershed landscape (ARC/INFO GIS) is merged with farm optimization (linear programming) and sediment and chemical transport (AGNPS) models. Enhanced targeting of non-point source pollution to remedial policy and management initiatives result. The implications of which...

Many agricultural economists are not familiar with case study research, yet the approach is a useful means of collecting data, and building and testing theory. Case study research has a prescribed set of objectives, epistemology, methodology, and methods that have been developed and tested in a...

The present report presents the NRLO views on knowledge and innovation priorities for Dutch agribusiness in the years ahead as seen in an international perspective. Knowledge and innovation priorities are highlighted against the backdrop of key challenges facing Dutch agribusiness in the years...
