Price distortions and resource use efficiency in a Pakistani province
利用1987-88年巴基斯坦西北边境省的农场调查数据，估计超越对数利润函数，检验技术和价格效率假设，发现价格效率假设未被拒绝，大型农场技术效率最高，且劳动力市场不存在价格低效率。
The objectives of this paper are to test the hypotheses of technical and price efficiency through estimating translog profit functions using the 1987-88 farm level survey data from the North West Frontier Province (NWFP) of Pakistan. The price efficiency hypothesis cannot be rejected while technical inefficiency is lowest for large sized farms. Despite the widespread use of family labor in NWFP, we find that there is no price inefficiency in the labor market when family labor is imputed at the appropriate wage rate. Moreover, there is no evidence of inefficiency in any of the input or output markets. This is plausible since the region is highly developed and a number of opportunities for work outside the family farm exist. Copyright 1993 by Oxford University Press.
