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...

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...

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 paper investigates the linkages between technological change and production risk, with an application to corn. The effects of technology on risk exposure are analyzed. We define technological progress to be risk-increasing (risk-decreasing) if it increases (decreases) the relative risk...

It is widely believed that the Green Revolution had very little effect in unfavourable or marginal environments. Many researchers have been concerned about the slow progress of technical change in marginal environments and the level of research resources allocated to these areas. This paper...

This paper presents evidence of recent adoption rates of disease resistant bean varieties (RVs), the farm-level benefits of RV adoption, and the ex post rate of return to disease resistant bean research in Honduras. Results from a farm-level survey in 2001 in the two principal bean-producing...

Expenditures on agricultural research in the public sector, including the International Agricultural Research Centers (IARCs) have stagnated and in some cases, declined sharply in recent years. This has focused attention on issues of efficiency of agricultural research systems, especially the...

Productive efficiency for Chinese hybrid and conventional rice production is estimated using a dual stochastic frontier efficiency decomposition model. Results reveal significant differences in technical and allocative efficiency between conventional and hybrid rice production, and indicate...

This paper describes the findings of a study that used a multi-market model to assess the potential impact of improved maize technologies on the welfare of various types of rural and urban households in Kenya. The modelling results indicate that technologies developed for high potential regions...

This paper addresses the prospects for technical change in the in·igated rice sector of Senegal, and measures ex-ante the economic returns to recent research efforts. In 1994, three new rice varieties were released to farmers in the Senegal River Valley (SRV), the major irrigated rice region in...
