Episode notes
College Wage Premium Is Largely Selection
- The raw college wage premium over high school (about 73%) overstates the causal effect because selection matters.
- After controls and modern techniques Bryan Caplan estimates roughly 60% of the raw gap is causal, so schooling still helps but less than headline numbers imply.
Most Degree Value Comes From Signaling
- Education has two models: human capital (skills taught) and signaling (credentials certify traits).
- Caplan argues signaling explains a large share and estimates about 80% of the payoff comes from signaling rather than skill building.
Degrees Signal Conformity And Work Ethic Too
- Signaling covers more than IQ: it signals conscientiousness, work ethic, and conformity via a long attrition process.
- Employers infer smart but uncredentialed applicants likely lack these traits, reducing their hireability.
