Abstract

[spa] Estimación de frontera de producción y de la ineficacia técnica. . Aplicación a las empresas tunecinas, . por Mohamed El Arbi Chaffai.. . Se presenta ante todo una síntesis relativa a la estimación de las fronteras paramétricas de producción y de la ineficacia técnicas de las firmas. Luego fue estimada una frontera estocástica de producción para seis sectores industrials de la economía tunecina, en un corte transversal de 385 empresas. Los resultados obtenidos muestran que la especificación translog es más significativa que la especificación Cobb-Douglas, y que el grado de ineficacia técnica en estos sectores varía entre 24 % y 37 %. [eng] Estimates of production frontier and technical inefficiency in a cross-section of tunisian companies, . by Mohamed El Arbi Chaffai.. . This paper summarizes the methods used to estimate parametric production frontiers and the technical inefficiency of firms. A stochastic production frontier based on a cross-section of 385 companies is estimated for six industrial sectors of the tunisian economy. The translog specification is more significant than the Cobb-Douglas one, and the degree of technical inefficiency in the sectors examined ranges from 24 % to 37 %. [ger] Eine Schätzung der Produktionsgrenzen und der technischen Ineffizienz. . Eine Anwendung auf die tunesischen Betriebe, . von Mohamed El Arbi Chaffai.. . Zunächst wird eine Schätzung der parametrischen Produktionsgrenzen und der technischen Ineffizienz der Betriebe zusammenfassend dargestellt. Anschliessend wird eine stochastische Produktionsgrenze für sechs Industriezweige der tunesischen Wirtschaft anhand einer Querschnittuntersuchung von 385 Betrieben geschätzt. Die gewonnenen Ergebnisse zeigen, dass die Translog-Spezifrkation eine höhere Aussagekraft hat als die von Cobb-Douglas und dass der technische Ineffizienzgrad in diesen Sektoren zwischen 24 % und 37 % schwankt.
