| Tiivistelmä: | Education may enhance earnings either because of human capital increases or by signalling unobservable worker attributs. The theoretical model of this study provides a direct sinal measure as the difference between required and necessary qualifications, forming the basis for an ordered-probit model of discrete differences between required and necessary qualifications that depend on firm, job, and worker attributes. Estimates support the model's preductions, providing a continuous, predicted signal measure for second stage, gender-specific return to a signal and indicate a downward bias in the return to education from excluding the signal measure. |
