This paper examines changes in agricultural productivity in 18 developing countries over the period 1961-1985. We use a nonparametric, output-based Malmquist index and a parametric variable coefficients Cobb-Douglas production function to examine, whether our estimates confirm results from other...

This paper focuses on the economic consequences of droughts for the irrigation sector. We develop a dynamic-recursive mathematical programming farm model that assumes imperfect mobility of capital and labour as well as rational expectations about future water availability. The model is...

The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at...
