This paper compares standard stochastic frontier models for panel data with a number of recently developed models designed to remove unobserved heterogeneity from the inefficiency component. Results are used to construct a generalised Malmquist total factor productivity (TFP) index. We conclude...

In this paper a probit model is used to assess the factors that will influence the decision of Irish farmers to adopt GM technology should they be given a choice in the near future of selecting between GM and non-GM varieties of crops. The theory underlying the model emanates from the wide...

This article compares standard stochastic frontier models for panel data with a number of recently developed models which attempt to control for unobserved heterogeneity in the inefficiency component. Results are used to construct a generalized Malmquist Total Factor Productivity (TFP) index for...
