Production risk and technical inefficiency in Russian agriculture
研究了俄罗斯农业中生产风险和技术低效率对产量波动的影响，利用1996-2001年443家大型农业企业的面板数据，发现考虑投入对风险和低效率双重影响的模型比传统随机前沿模型更适用。
This study investigates production risk and technical inefficiency as two possible sources of the production variability that characterised Russian agriculture during the last decade. The empirical analysis is conducted using panel data from 1996 to 2001 on 443 large agricultural enterprises from three regions in central, southern and Volga Russia. A production function specification accounting for the effect of inputs on both risk and technical inefficiency is found to describe production technologies of Russian farms more appropriately than the traditional stochastic frontier formulation.
