Résumé
Following the recent work of G ́omez–D ́eniz and P ́erez–Rodr ́ıguez (2014), this paper extends the results obtained there to the normal–exponential distribution with dependence. Accordingly, the main aim of the present pa- per is to enhance stochastic production frontier and stochastic cost frontier modelling by proposing a bivariate distribution for dependent errors which allows us to nest the classical models. Closed–form expressions for the error term and technical efficiency are provided. An illustration using real data from the econometric literature is provided to show the applicability of the model proposed.
