In this paper, we propose an alternative econometric framework for estimating and decomposing productivity change that does not require a distribution for inefficiency or the uncorrelatedness between inefficiency and the regressors. We develop our methodology for the input-oriented radial...

We examine whether the European settlement institutions are technically efficient. This is done by means of estimating a translog cost function, and investigating whether scale economies are fully exploited. Since the sample is quite heterogeneous, fixed effects regression is introduced. From...

Necessary and sufficient conditions are given for the existence of optimal k-dimensional quantizers that minimize a distortion measure E{W(X)C(X - Q(X))}. An example is given in which a globally optimal quantizer does not exist.
