Abstract:
In this paper we investigate the importance of labor market institutions such as unemployment insurance, unions, firing regulation and minimum wages for the evolution of wage inequality across countries. We derive a simple log-linear equation of the wage differential as a function of the institutional parameters, total factor productivity, final good prices and relative skill supply. Our estimates for 11 OECD countries imply that labor market institutions can account for a large part of the change of wage inequality across countries after controlling for time and country effects.
