In this paper we compare two flexible estimators of technical efficiency in a cross-sectional setting: the … examples. We find that the reliability of efficiency scores critically hinges upon the ratio of the variation in efficiency to …

We evaluate the determinants of matching efficiency changes through a stochastic Cobb- Douglas production frontier … model extended to allow the efficiency coefficient to depend on variables meant to capture workers and firms characteristics … efficiency changes observed over time and some 25% of the cross regional differences can be explained in terms of changes in …
