Heterogeneity and Efficiency of Meat Processing Companies in the Czech Republic
Original language description
In this paper different ways of considering heterogeneity in stochastic frontier models based on data about Czech meat processing farms are studied. Recent studies proved that food processing firms? heterogeneity can influence the result of efficiency estimation. It is possible to take heterogeneity into account by including those effects in the mean and/or variance of distribution of inefficiency (observed heterogeneity) or by randomizing some parameters of the model (unobserved heterogeneity). For empirical study panel data set from the years 2005? 2012 contained 757 observations of 130 meat processing companies was used. All models were estimated in the form of Translogarithmic production function. The models with observed heterogeneity (heterogeneity in variance and Equality Constrained Scaling Model) and unobserved heterogeneity (True Random Effects and Random Parameters Model) were compared to Aigner, Lowell and Schmidt (ALS) model without heterogeneity by statistical tests.
