Which Wage Dispersion Matters to Firms' Performance?

Research on wage dispersion and firm performance focuses on intra-firm and inter firm effects irrespective of workers’ profession. We extend the analysis by considering dispersion within professions, within and across firms and within professions economy-wide. We find that the intra-firm dispersion of wages, which research so far has focused on, has limited effects on productivity compared to the economy-wide wage dispersion within the professions. As Swedish firms have differentiated wages among employees during the last 10-15 years also the economywide dispersion within professions has increased thus contributing considerably to the strong performance of the Swedish economy in the late1990.s
