China’s college admissions increased fivefold between 1998 and 2009. While the college premium for young workers declined, that for senior workers increased in this period. In our general equilibrium model, a rising demand for skills (education and experience) explains both trends. A demand shock leads to an expansion in the elastic college enrollment, depressing the college premium for young workers. With an inelastic supply, experienced college graduates continue to enjoy a rising premium. Despite the low immediate premium, young individuals continue to flood into colleges because they foresee high lifetime returns. The lifetime college premium differs significantly from the cross-sectional premium estimated by the Mincer equation. Simulations match empirical results well.
