Various forms of research and development (R&D) activities have evolved over the past few centuries as part of the scientific system. Of particular interest is the unique pattern of R&D activities that have developed within agricultural and natural resource sectors. The evolution of...

Technical efficiency of wheat farms in eastern England is measured through the estimation of a stochastic frontier production function using panel data for the 1993-1997 crop years. Variations in the technical efficiency index across production units are explained through a number of managerial...

Estimated rates of return to research are distorted by problems of attributing the credit for particular research results, or for particular research-induced productivity increases, among research expenditures undertaken at different times, in different places, and by different agencies. A...

We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India's total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers....

A meta-analysis is perfonned to review empirical estimates of technical efficiency (TE) in developing country agriculture. The objective of the study is to contribute to a better understanding of the factors that influence estimates of mean TE. A data set of 51 observations of TE from 32 studies...

The Iranian government encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. In this paper, using a Cobb-Douglas frontier production function, a simple relationship between a fatm-level output-based technical efficiency measure...

The rural non-farm sector has traditionally been viewed as a low-productivity sector which produces low quality goods. It is often expected to wither away as a country develops. Recent years have seen a shift away from this position towards recognition that the rural non-farm sector can, and...

Demand models were estimated for five commodities using annual retail level Japanese data. Estimates were made with the Houthakker-Taylor [Houthakker, H.S .• Taylor, L.D., 1970. Consumer Demand in the United States: Analysis and Projections. Harvard University Press, New York, MA] state...

Achieving an appropriate resource allocation structure usually revolves around the farm manager. His or her ability is crucial to success. Yet, most farmers learn by experience and/or through various courses that concentrate on technical, production economic and related aspects. Putting more...

The objective of this paper is to present econometric evidence of the effects of economic incentives and institutions on national aggregate private agricultural R&D investments. An econometric model of national aggregate annual private R&D investment is specified and fitted to panel data...
