The two - tier stochastic frontier framework (2TSF): theory and applications, models and tools
Abstract
This PhD thesis, written in English with a summary in Greek, is a monograph on the Two-tier Stochastic Frontier model (2TSF). The model is capable of estimating the effects of two latent variables of opposite direction on the dependent variable in a regression context, and it has been applied to a wide variety of economic and non-economic phenomena. The thesis starts with a review of the literature, and then moves on to critically examine the various structural foundations that have been proposed for the model in the past. Then, five new 2TSF statistical models are presented in every technical detail so that they can be readily implemented, enlarging the applied scope of the model. Then we present two economic models, one where a new, targets-based bilateral Nash bargaining model is presented, and another for the contribution of Management to the output of a firm. Both can be estimated by a 2TSF econometric model. Five short empirical applications showcase the various theoretical resul ...
