Imperfections du marché du travail et modèles d’équilibre général calculables : une revue de littérature


Author Info

  • Mohamed Ali Marouani



(english) This articles aims at discussing different labour market modelling choices used in applied general equilibrium models and the consequences of these choices on the results obtained when simulating various tax policy shocks with AGE models. Taking into account the imperfect functioning of the labour market in applied models does not have effects on employment issues only. It also allows improving the estimation of the adjustment capacities of an economy facing a shock by modelling explicitly unemployment and wage differentials. Nevertheless, the difficulty of empirical validation of the labour market specifications chosen weakens the use of these models for policymaking. _________________________________ (français) L’objectif de cet article est de discuter les choix de modélisation du fonctionnement du marché du travail adoptés dans les modèles d’équilibre général appliqués et les conséquences de ces choix sur les résultats obtenus en simulant divers chocs de réformes fiscales avec ce type de modèles. La prise en compte des imperfections ou caractéristiques institutionnelles du marché du travail n’a pas seulement des effets sur les résultats des MEGC en termes d’emploi. Elle permet aussi d’améliorer l’estimation des capacités d’ajustement des économies face au choc en modélisant explicitement l’existence de chômage ou de différentiels de salaires intersectoriels. Néanmoins, la difficulté de validation empirique des spécifications du marché du travail retenues fragilise l’utilisation de ces modèles dans une optique d’aide à la décision.
