		| This study addresses endogenous labor force participation based on a search and matching model with workers' productivity dispersion within different skill groups. I show that equilibrium vacancy creation can be both excessive and insufficient from the viewpoint of economic efficiency, depending on the relative share of workers in a high-skill group. |
