Modelling farm production decisions under an expenditure constraint
使用间接生产函数和随机前沿方法，分别估计预算约束和技术无效率导致的产出损失，发现俄罗斯多数农场受支出约束，平均产出损失20%。
We use the indirect production function approach in the stochastic frontier framework to estimate separately the output losses due to the presence of a budget constraint and technical inefficiency. We develop a methodology for estimating the severity and testing the significance of the expenditure constraint at individual producer level. Our results, based on the farm data from three Russian regions from 1999 to 2003, show that the majority of the farms studied were expenditure-constrained during the study period. Expenditure constraints caused, on average, a potential output loss of 20 per cent. Output loss due to technical inefficiency, on average, is found to be around 13 per cent.
