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. %K bilateral monopoly %K wage differential by skill %K labor market institutions %K country panel data
