Duality in the Berger - Mester Profi t Function

In an in fluential paper Berger and Mester (1997) have proposed the alternative profi t function. It is widely thought that the alternative profi t function does not result in any useful duality properties. We show, in this study, that quite the opposite is true and, in fact, one can recover, through, duality, a wealth of information such as: Measures of market power, returns to scale and features of the pricing opportunity set directly from the Berger-Mester alternative pro t function
