This discussion paper deals with the estimation of a random coefficient model. The virtue of this approach is that it considers firm heterogeneity, which conventional SFA models do not. Applying the model to Polish farms, the results indicate that the conventional random and fixed effect models...

The availability of efficiency estimation software - freely distributed via the internet and relatively easy to use - recently inflated the number of corresponding applications. The resulting efficiency estimates are used without a critical assessment with respect to the literature on...
