Optimal Wage Indexation and Aggregate Fluctuations

Author

Abstract

The business cycle implications of optimal wage indexation are investigated in a dynamic general equilibrium model with wage contracts. As in Gray's seminal contribution on wage indexation, it is shown that the optimal degree of indexation depends on the relative volatilities of monetary and real shocks. We establish the link between optimal wage indexation and (i) contract lenght, (ii)the persistence of real shocks and (iii) the share of capital in the production. The model can yield a low correlation between hours worked and the productivity of labor and is also able to generate a ratio of the volatility of hours worked to the volatility of productivity and a ratio of the volatility of output to the volatility of hours worked that are broadly consistent with the facts. Les effets cycliques de l'indexation optimale des salaires sont examinés dans un modèle dynamique d'équilibre général avec contrats de salaire. Tout comme dans le texte marquant de Gray sur l'indexation des salaires, nous montrons que le degré optimal d'indexation dépend de la volatilité relative des chocs monétaires et réels. Nous faisons le lien entre l'indexation optimale des salaires et (i) et la durée des contrats, (ii) la persistence des chocs réels et (iii) la part du capital dans la production. Le modèle engendre une corrélation faible entre les heures de travail et la productivité des travailleurs ainsi que des ratios de la volatilité des heures travaillées à la volalilité de la productivité et de la volatilité du PNB réel à la volatilité des heures travaillées qui sont généralement en harmonie avec les faits.
