Doubly Heteroscedastic Stochastic Production Frontiers with an English Cere al Farms.

Hadri, K.; Guermat, C.; Whittaker, J. - Business School, University of Exeter - 1998

In previous studies, measures of technical inefficiency 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 suggested...
