The recent rural reforms in China have had great effects on agricultural production and productivity as well as rural household consumption. While much has been written on production and productivity effects of these reforms, very few Chinese studies have attempted to analyze the changes in...

An econometric approach using international and national yield trial data is employed to estimate a spillover matrix for wheat varietal technology. The global spillover matrix is estimated based on international yield trial data from 1979-80 to 1987-88, that include 195 international trial...

Cropping intensity in the cotton-wheat areas of Pakistan's Punjab is well below its potential, and also significantly lower than in neighbouring areas of India's Punjab. Analysis of annual cropping intensity indicates that access to irrigation water is the major factor explaining differences in...

It has generally been assumed that the inferences of the induced technical change model with respect to the direction of technical change could not be expected to hold for the centrally planned economies. In this paper we test three hypotheses generated from the induced technical change...

We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India's total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers....

Many economists have advocated and applied total social factor productivity (TSFP) (i.e., total factor productivity estimated with both market and non-market inputs and externalities, and with all factors valued at social prices) as a single all-embracing measure of agricultural sustainability....
