Este trabajo presenta un modelo de frontera estocástica con parámetros aleatorios en el componente de ineficiencia aplicado al sector bancario. Este modelo permite capturar la influencia de las exposiciones de riesgo sobre la eficiencia bancaria y distingue estos efectos entre bancos con...

In this paper, we study the so-called “wrong skewness” anomaly in Stochastic Frontiers (SF), which consists in the observed difference between the expected and estimated sign of the asymmetry of the composite error. We propose a more general and flexible specification of the SF model,...
