The aim of this article is to analyse the technical efficiency of Hungarian crop farms between 2001 and 2009 using panel data. We employ both standard stochastic frontier analysis and latent class model (LCM) to estimate technical efficiency. Our results suggest that technological heterogeneity...

In this paper, we perform an extensive Monte Carlo study of the finite sample properties of different estimators for panel data sample selection models. The estimators investigated are various two-step estimators and maximum likelihood estimators with simultaneous equations for the samle...
