Spillover effects of minimum wages : theory and experimental evidence

We study the spillover effects of minimum wages in a laboratory experiment. In a bilateral firm-worker bargaining setting, we find that the introduction of a minimum wage exerts upward pressure on wages even if the minimum wage is too low to be a binding restriction. Furthermore, raising the minimum wage to a binding level increases the bargained wage above the new minimum wage level. While the Nash solution cannot explain the existence of spillover effects, the Kalai-Smorodinsky solution yields results that are qualitatively more in line with our experimental findings. -- minimum wage ; bargaining ; Kalai-Smorodinsky solution ; labor market experiments
