Journal of Productivity Analysis, 2015, vol. 43, issue 2, 225-230

Abstract: In the context of the two-tier stochastic frontier model, we present a new closed-form stochastic specification, the half-normal one. Expressions to calculate average and conditional measures of inefficiency are provided, for regression specifications in levels and in logs. Some results related to model validation and maximum likelihood estimation are also presented. Copyright Springer Science+Business Media New York 2015
