ABSTRACT La estimación de funciones de producción suele basarse en el supuesto de que la tecnología es común para todos los productores. Sin embargo, en la muestra puede haber empresas que usen tecnologías diferentes. En este trabajo se emplea un modelo de clases latentes para estimar la tecnología de varios sistemas de producción de explotaciones lecheras según su grado de intensificación. Los resultados de esta estimación se comparan con los obtenidos usando otras dos aproximaciones. Una, el modelo clásico de frontera estocástica. La otra consiste en dividir la muestra mediante un análisis cluster y estimar una frontera de producción distinta para cada uno de los grupos. El análisis empírico se realiza con un panel completo compuesto por 169 explotaciones lecheras asturianas para el período comprendido entre 1999 y 2004.

    ABSTRACT: This paper analyses the importance of productive specialization in explaining cost efficiency differences between banking companies. Taking as reference the Spanish banking sector during the period 1985-1996, the study shows that if cost efficiency measurements are corrected for the effect of different specialization by the estimation of separate frontiers for four different groups of competitors, the efficiency of companies improves. The behaviour of costs would thus be compatible with that of other competition indicators, reflecting the effects of a more competitive situation in the Spanish banking sector at present than at the start of the period considered.

    ABSTRACT: This paper examines several extensions of the stochastic frontier that account for unmeasured heterogeneity as well as firm inefficiency. The fixed effects model is extended to the stochastic frontier model using results that specifically employ its nonlinear specification. Based on Monte Carlo results, we find that the incidental parameters problem operates on the coefficient estimates in the fixed effects stochastic frontier model in ways that are somewhat at odds with other familiar results. We consider a special case of the random parameters model that produces a random effects model that preserves the central feature of the stochastic frontier model and accommodates heterogeneity. We then examine random parameters and latent class models. In these cases, explicit models for firm heterogeneity are built into the stochastic frontier. Comparisons with received results for these models are presented in an application to the U.S. banking industry.

    ABSTRACT: This paper proposes a new approach to handle nonparametric stochastic frontier (SF) models. It is based on local maximum likelihood techniques. The model is presented as encompassing some anchorage parametric model in a nonparametric way. First, we derive asymptotic properties of the estimator for the general case (local linear approximations). Then the results are tailored to a SF model where the convoluted error term (efficiency plus noise) is the sum of a half normal and a normal random variable. The parametric anchorage model is a linear production function with a homoscedastic error term. The local approximation is linear for both the production function and the parameters of the error terms. The performance of our estimator is then established in finite samples using simulated data sets as well as with a cross-sectional data on US commercial banks. The methods appear to be robust, numerically stable and particularly useful for investigating a production process and the derived efficiency scores.
