Technical, allocative and economic efficiency measures are derived for a sample of swine producers in Hawaii using the parametric stochastic efficiency decomposition technique and nonparametric data envelopment analysis (DEA). Efficiency measures obtained from the two frontier approaches are...

Studies of the rates of return to research have usually been based on the implicit assumption that if there were no research, then there would be neither growth nor decline in output or productivity. In the case of livestock, particularly in southern Africa, which has a sub-tropical disease...

The economic surplus approach is used to estimate the returns to federal investments in dairy cattle research in Canada. A national supply function is estimated using time series data. Lagged research expenditures are included as explanatory variables in the model, facilitating the calculation...

A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate...

The introduction of new forages and milk marketing improvements was projected to permit even the smallest modeled farms in a western Kenya region to adopt dual-purpose goats and thereby improve family income and nutrition. Expanded credit permitted modeled medium and large farms, especially, to...

The rice industry in New South Wales, Australia, has benefited from the international flow of germplasm, as have other industries. The aim in this paper is to identify those international flows, and to value their contributions to the industry. Analysis is made of the origins and pedigrees of...

Using a simple neoclassical type growth model including both man-made and natural capital as inputs to production, the theoretical basis for aU-shaped relationship between agricultural intensification and farm household investment in renewable resource capital is established. As development 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...

This paper compares the direct and indirect effects of rest-of-the-world (ROW) policy on welfare in country A: the direct effect due to the change in world price caused by the policy in the absence of research/promotion-induced shifts in supply/ demand, and the additional (or indirect) effect of...
