In previous studies, measures of technical inefficiency effects derived from stochastic production frontiers have been estimated from residuals which are sensitive to specification errors. This study corrects for this inaccuracy by extending the doubly heteroscedastic stochastic cost frontier...

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

This paper presents findings from a major research study investigating management training and development (MTD) activity within small and medium‐sized enterprises (SMEs) in the East Midlands. Despite the fact that the academic evidence linking training and development with business...
