Technical change and its measurement is a fascinating subject. The various procedures to measure technical change fall into two categories (i).The parametric approach and (ii). The non-parametric approach. In theformer case, a parametric production function is postulated a priori, using it as basic tool, technical change is estimated. The present book aims at presenting a method to measure technicalprogress relaxing the assumptions of full profit efficiency and constant returns to scale. The method is essentially non-parametric, in which wesolve a number of linear programming problems, first...
