Returns to investment on agricultural research in the Punjab

, : Returns to investment on agricultural research in the Punjab. Indian Journal of Agricultural Economics 32(3): 202-207

Following closely the approach adopted by Griliches to account for the 'measured productivity growth', an attempt is made to identify the factors determining the level of aggregate agricultural productivity in the Punjab. Aggregate agricultural production functions of the unrestricted Cobb-Douglas type, based on cross-district and time-series data, were estimated for the pre-technology (1960-65) and post-technology (1969-72) periods.
