Abstract

[spa] Rendimientos, sustituciones y adelantos técniços en el servicio público tunecino de telecomunicaciones, . por Siwar Damak-Bahloul.. . Nuestro objetivo consiste en analizar la estructura productiva del sector de las telecomunicaciones en Túnez utilizando un método econométrico fundado en la especificación de coste translog. Para contribué al debate acerca de la dereglamentaciôn actual en numerosos países desarrollados, tratamos en primer lugar de determinar si el sector estudiado constituía un monopolio natural utilizando medidas fundadas en los resultados de estimación de la función de coste. Acto seguido, tratamos de evaluar las sustituciones entre factures y estudiar las consecuencias del adelanto técnico en la combinación de los factores de producción. Por último, sometimos a prueba algunas propiedades estructurales de la tecnología. [eng] Profitability, Substitution and Technical Progress in Tunisian Public Service Telecommunications, . by Siwar Damak-Bahloul.. . Our objective was to analyze the productive structure of the telecommunications sector in Tunisia using an econometric approach based on a Translog cost function. To shed some light on discussions on the subject of deregulation in many developed countries, we basically tried to determine whether or not the sector under study is a natural monopoly by using measurements based on cost function estimates. We then attempted to assess substitutions between factors and to examine the effect of technical progress on the combined inputs. Lastly, we tested some of the structural properties of technology. [ger] Erträge, Substitutionsmöglichkeiten und technische Fortsçhritte im öffentlichen Dienst der Telekommunikation in Tunesien, . von Siwar Damak-Bahloul.. . Unser Ziel ist es, die produktive Struktur des Telekommunikationssektors in Tunesien mittels eines ökonometrischen Ansatzes auf der Grundlage einer Translog-Kostenfunktion zu analysieren. Als Beitrag zur Diskussion über die aktuelle Deregulierung in zahlreichen entwickelten Ländern versuchen wir mittels Messungen auf der Basis der Schätzungsergebnisse der Kostenfunktion hauptsächlich festzustellen, ob es sich beim untersuchten Sektor um ein natürliches Monopol handelt. Danach wird der Versuch unternommen, die Substitutionsmöglichkeiten zwischen den einzelnen Faktoren zu bewerten und die Auswirkung des technischen Fortschrittsauf die Kombination der Produktionsfaktoren zu untersuchen. Schließlich werden noch einige strukturelle Eigenschaften der Technologie analysiert. [fre] Rendements, substitutions et progrès techniques dans le service public tunisien des télécommunications, . par Siwar Damak-Bahloul.. . Notre objectif est d'analyser la structure productive du secteur des télécommunications en Tunisie, au moyen d'une approche économétrique basée sur la spécification de coût translog. Pour ajouter au débat sur la déréglementation en cours dans de nombreux pays développés, nous cherchons principalement à déterminer si le secteur étudié est un monopole naturel au moyen de mesures basées sur les résultats d'estimation de la fonction de coût. Ensuite, nous essayons d'évaluer les substitutions entre facteurs et d'étudier l'incidence du progrès technique sur la combinaison des facteurs de production. Enfin, nous testons certaines propriétés structurelles de la technologie.
