Stochastic Frontier Analysis Using SFAMB for Ox

Abstract

SFAMB is a flexible econometric tool designed for the estimation of stochastic frontier models. Ox is a matrix language used in different modules, with a console version freely available to academic users. This article provides a brief introduction to the field of stochastic frontier analysis, with examples of code (input and output) as well as a technical documentation of member functions. SFAMB provides frontier models for both crosssectional data and panel data (focusing on fixed effects models). Member functions can be extended depending on the needs of the user.
