Several approaches exist for the estimation of technical efficiency. In this paper the four most relevant ones (Data Envelopment Analysis, Stochastic Production Frontiers, Panel Data and Distance Functions) have been compared. The different approaches have been applied to the to the Spanish Trawl fishery that operated in Moroccan waters. The study highlights some of the problems arising from th...
This paper develops a dynamic Luenberger productivity growth indicator and decomposes it to identify the contributions of technical change, technical efficiency change and scale change. The Luenberger productivity growth indicator is estimated using Data Envelopment Analysis. The empirical application focuses on panel data of Spanish meat processing firms over the period 2000-2010. The dynamic ...
Nonlinear panel data models naturally arise in economic applications, yet their analysis is challenging. Here we provide a progress report on some recent advances in the area. We start by reviewing the properties of random-effects maximum likelihood. We emphasize a link with Bayesian computation and Markov Chain Monte Carlo, which provides a convenient approach to estimation and inference. Rela...
