TL;DR: In this paper, the authors present the theoretical foundations and the procedure to follow in consistently modelling imperfect competition in a traditional computable general equilibrium trade model, showing that very limited procompetitive effects are to be expected from trade liberalization.
Abstract: The new trade theory shows that taking into account imperfect competition and economies of scale can drastically modify our predictions concerning the impact of trade policy. However, despite the apparent importance of these phenomena and the extent of current trade liberalization in developing countries, there are extremely few empirical trade analyses which consider them. Further, we find that the principal exception to this rule is a study that contains a modelling inconsistency leading to a considerable overestimation of the pro-competitive effects of trade liberalization. We present in detail the theoretical foundations and the procedure to follow in consistently modelling imperfect competition in a traditional computable general equilibrium trade model. An illustration is then provided through an analysis of Tunisian trade policy options which indicates that very limited pro-competitive effects are to be expected from trade liberalization. La nouvelle theorie du commerce international demontre que la presence de concurrence imparfaite et d’economies d’echelle peut modifier de maniere radicale les impacts de politiques commerciales. Toutefois, malgre l’ampleur apparente de ces deux phenomenes dans les pays en developpement et les reformes commerciales qui y sont presentement appliquees, tres rares sont les etudes empiriques qui en tiennent compte. De plus, nous montrons que la principale etude qui fait exception contient une incoherence de modelisation qui mene a une surestimation considerable de l’effet dit procompetitif de la liberalisation commerciale. Nous presentons en detail les fondements theoriques et la procedure a suivre pour une integration coherente de la concurrence imparfaite dans un modele traditionnel d’equilibre general calculable. Le fonctionnement du modele est ensuite illustre a travers une application a la Tunisie, application qui indique que l’effet procompetitif a esperer de la liberalisation commerciale y est faible.
