A Generalized Measure of Farm-Specific Technical Efficiency

Abstract: Single measures of farm-specific technical efficiency over time are calculated for rice farms in Central Luzon, the Philippines, from the residuals of a stochastic frontier production function. Panel data from the International Rice Research Institute's periodic "Loop Survey" are used. Results show a narrow range of efficiency between 84% and 95% across the twenty-two farms, so that there is limited scope for increasing output by resource reallocation. A comparison is made with measures of technical efficiency using traditional covariance analysis.
