Abstract:
We analyze the Spence education game in experimental markets. We compare a signaling and a screening variant, and we analyze the e.ect of increasing the number of employers from two to three. In all treatments, there is a strong tendency to separate. More efficient workers invest more often and employers bid higher for workers who have invested. More efficient workers also earn higher wages. Employers' pro/ts are usually not different from zero. Increased competition leads to higher wages only in the signaling sessions. We /nd that workers in the screening sessions invest more often and earn higher wages when there are two employers.
