This paper proposes a theoretical framework where "within graduates" wage inequality is related to overeducation/educational mismatch in the labor market. We show that wage inequality may arise because of inefficient self-selection into education in the presence of ability-complementary technological progress and asymmetric information…

Applies comparative techniques originated by K. Wolpin and G. Psacharopulos to discriminate between the "weak" and "strong" screening hypotheses, employed to determine whether societal investment in upgrading or expanding education is justified. Controlling for sample selection, this study finds evidence for weak screening in…
