使用灵活(超越对数)生产函数,在利润最大化框架下估计印度西孟加拉邦227个农场的技术和配置效率,发现平均技术效率为75.46%,多数农场对化肥、粪肥、人力和畜力等内生投入使用不足。

Abstract

Abstract This paper uses a flexible (translog) production function to estimate efficiency of 227 farms from West Bengal, India. We consider estimation of technical and allocative inefficiencies using a profit maximising framework which accommodates both endogenous and exogenous inputs. The maximum likelihood method of estimation developed in this paper is based on the production function and the first‐order conditions of profit maximisation. Farm‐specific technical and allocative inefficiencies are also estimated. Empirical results show that the mean level of technical efficiency is 75.46% while the best farm is 85.87% efficient (technically). So far as allocative efficiency is concerned the majority of the farms are found to be under‐users of the endogenous inputs, viz., fertiliser, manure, human and bullock labour.
