Education and Signaling: Evidence from a Highly Competitive Labor Market.

This paper directly tests for differences in returns to education between the employed and self-employed in Hong Kong.

This pattern persists for both genders, when accounting for self-selection into employment status and when accounting for self-employed professionals who signal. [ABSTRACT FROM AUTHOR]
