Minimum wage restrictions and employee effort in incomplete labor markets: An experimental investigation

A minimum wage raises average wages along with modest increases in employees' average effort levels, generating a Pareto improvement in social welfare. The minimum wage reduces effort in the neighborhood of the minimum, but has no systematic effect on effort levels at higher wages. As a consequence average effort increases modestly with a minimum wage as it raises average wages. Similar results are reported within groups, both when introducing and eliminating a minimum wage, although the within group effects of introducing a minimum wage are stronger than dropping it.
