Low-Wage Labor Markets and the Power of Suggestion

The paper argues that a non-binding minimum wage may serve as a focal point which facilities tacit collusion by low-wage employers, effectively pulling down wages of the lowest-paid workers. This can explain the puzzle as to why the minimum wage does not reduce employment, as predicted by the traditional economic theory. A simple game-theoretic argument explains when collusion emerges. The hypothesis is tested using the 1990-2002 CPS data on service occupation workers. The results suggest that during this period, on average 19.3%, and as much as 31% of service occupation workers, who earned minimum wage or less, could had been affected by collusive wage-setting.
