The PROCISUR cooperative research programme is an agreement among Argentina, Brazil, Chile, Bolivia, Paraguay, and Uraguay. This paper analyses its impact in terms of rates of return, based on an analysis of the programme as it affects productivity changes in wheat, maize, and soyabeans in the...

This paper extends Bresnhan's market power measure, which can be estiamted exonometrically, to marketing firms that have potential for price discrimination. An investigation of Japanese soyabean markets during 1973-78 using the model reveals an episode in which Japanese importers exercised some...

The economic dimension of science has been one of the most treated problems in economics during the past three and a half decades. Over 6,000 publications appeared on the assessment of research results; several hundred formulae have been proposed to measure the efficiency of research workers,...

This paper addresses the well-known paradoxes of high rates of protection, underinvestment in agricultural research, and relatively high productivity that characterize developed country agriculture, while developing country agriculture is typically characterized by taxation of the sector,...

Knowledge of crop response to different moisture conditions is essential for analysing water allocation problems at the farm level. Inadequate experimental data and the time and cost involved in obtaining sufficient data for adequate estimations of yield-water relationships are probably the...
