Resumen de Firm and time varying technical and allocative efficiency: an application for port cargo handling firms
Ana María Rodríguez Álvarez, Beatriz Tovar de la Fe, Lourdes Trujillo Castellano
In this paper we present an econometric model to calculate firm and time-varying indexes of technical and allocative inefficiency following both the parametric and the error component approach. To achieve these aims, we estimate a system of equations for a translog input distance function and cost shares equations. In order to illustrate the methodology we present an application for cargo handling in ports using a panel data obtained from firms operating at the port of Las Palmas in Spain. This sector is a multioutput and regulated sector so the estimation of an input distance function is especially useful for our aims.
