Bryan Caplan on College, Signaling and Human Capital

Bryan Caplan talks to host Russ Roberts about the value of a college education. Caplan argues that the extra amount that college graduates earn relative to high school graduates is misleading as a guide for attending college--it ignores the fact that a sizable number of students don't graduate and never earn that extra money. Caplan argues that the monetary benefits of a college education have a large signaling component rather than representing the value of the knowledge that's learned. Caplan closes by arguing that the subsidies to education should be reduced rather than increased.
