Efficiency, Environmental Contaminants and Farm Size : Testing for Links Using Stochastic Production Frontiers

Hadri, Kaddour; Whittaker, Julie M. - 2004

This paper investigates whether there is any relationship between farm size, technical efficiency and the use of agrochemicals which are potentially environmentally contaminating. These questions are pertinent in the context of current EU policy decisions. Using two models of stochastic frontier...
