| Abstract: | This paper is an empirical application of the distance function to study the allocative efficiency of a regulated railway Spanish firm, RENFE, where the cost minimising hypothesis may be questioned. Besides and in contrast with other studies, the authors include the possibility of the presence of persistent allocative inefficiency. To achieve these aims, the authors have estimated a system of equations for the inputs distance function and cost shares using annual data over the period 1955-95. Using this procedure the authors have checked the presence of persistent allocative inefficiency, in particular a systematic overutilization of labour and under utilization of capital. Moreover the authors have found some empirical evidence that, since 1984, management contracts have improved the input allocation m Spanish railways. |
