Highly subsidized bread prices financed partially through wheat aid and overvalued currency have stimulated rapid growth in wheat consumption in Sudan at the expense of other staple grains such as sorghum and millet. Inefficient production methods and the resultant low wheat yields have caused...

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...

Simultaneous equation models of the soyabean sectors in Japan and Taiwan are developed and estimated through seemingly unrelated regressions. The models integrate domestic supply and demand for soyabeans, soyameal, and soyaoil as well as the livestock market. Based on the established models, the...

The system of exchange rates, border taxes, and subsidies- the agrimonetary system- is incompatible with the goals of EC-1992. This system has led to a breakdown in the concept of common pricing and to distrotions in trade patterns and has created large administrative costs to the EC....

A world net trade model is used to study the consequences of changes in meat consumption patterns in China. Results suggest that such changes would considerably depress world grain prices, especially those for maize and rice. The study also shows that grain consumption requirements in China...

Japanese agriculture is a family-farm-dominated industry. Farms have been transferred from generation to generation by inheritance. Recently, Japanese farms have faced difficulty in transfer of management to succeeding generations, resulting in an increase in the number of ageing farmers and in...

During the past decade, the degradation of the tropical forests has become a major topic in the worldwide discussion of the factors that threaten the long-term survival of the global ecological system. Undisputed in the context is the fact that agricultural production is among the major causes...

There is a rapid trend towards an ageing society in Japanese rural areas; aged farmers thus play an important part in agricultural production. The purpose of this paper is to analyse labour supply behaviour of aged farmers. After clarifying the main features of their labour supply, a labour...
