Abstract

In this paper, we develop a method to quantify the importance of regulation and market structure on the success of trade liberalization. For this purpose, we incorporate a single imperfectly competitive service sector that can take on various market structures into a standard computational general equilibrium model. We apply our framework to analyze the impact of allowing a single foreign telecom provider to enter Tunisia. If the regulation environment guarantees competition, Tunisia's welfare can improve up to 0.65 percent. If a cartel is formed between the domestic incumbent and foreign entrant, however, Tunisia's welfare can drop up to 0.25 percent. Our results thus call for Tunisia among other developing countries to step up its procompetitive regulatory reforms while liberalizing its telecom sector. Dans ce papier, nous développons une méthode permettant de quantifier l'importance de la réglementation et de la structure des marchés sur la libéralisation du commerce et sur son succès. À ces fins, nous incorporons un secteur unique et imparfaitement compétitif pouvant intégrer différentes structures de marché dans un modèle standard de calcul d'équilibre général. Nous appliquons notre cadre d'analyse afin d'étudier l'impact de l'entrée d'un seul fournisseur étranger en Tunisie. Nous trouvons que si la réglementation du marché y garantit la compétition, le bien-être de la Tunisie peut augmenter de 0,65 %. Cependant, s'il y a formation d'un cartel entre le réseau domestique et l'entrant étranger, le bien-être de la Tunisie peut baisser de 0,25 %. Nos résultats démontrent que tout en libéralisant son secteur des télécommunications, la Tunisie bénéficierait de réformes visant des régulations pro-compétitives.
