A Macroeconomic Model of Skill Mismatch within OECD Countries

This paper investigates the effect of the mismatch between workers' skills and the job requirements on the aggregate output and the earnings distribution. It develops a labor market model in which workers of different skills are allocated across jobs with different skill requirements, and this allocation is distorted by various government regulations. The model is calibrated to match the features of the earnings distribution and the extent of the skill mismatch reported by The Organization for Economic Co-Operation and Development (OECD) for 2015. The model is then used to evaluate the economic outcomes of eliminating government regulations leading to skill mismatch. I find that such a change, despite an almost negligible effect on aggregate output, has quite a significant impact on the distribution of earnings. More formally, output increase by merely 0.045%, while wages allocated to routine workers increases by 1.77% and wages allocated to specialized workers reduced by 10.52%.
