Functional Forms of Stochastic Frontier Production Functions and Models for Technical Inefficiency Effects: A Comparative Study for Wheat Farmers in Pakistan

摘要: This paper considers translog and Cobb-Douglas stochastic frontiers in which the technical inefficiency effects are defined by three different models. The models involved time-varying model, proposed Battese Coelli (1992), model for panel data, (1995), non-neutral frontier Huang Liu (1994). Technical change is also accounted Predicted efficiencies of wheat farmers estimates elasticities production with respect to inputs returns-to-scale parameter compared under specifications.
