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...

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 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...

How to maintain communal spaces is an important concern in many developing countries, particularly in urban environments. But what strategies can communities use to overcome the public goods problems involved in maintaining their local environment? This paper investigates whether changing the...
