The Returns to Education in Entrepreneurship Iversen, Jens; Malchow-Møller, Nikolaj; Sørensen, Anders The returns to education in self-employment are addressed in four different specifications of the relationship between log income and years of schooling. The specifications range from a standard Mincer equation with a constant percentage increase in income to an additional year of schooling to the most flexible specification with dummy variables for the different number of years of schooling split into different types of education. Based on the more flexible specifications, important non-linearities and heterogeneity in the returns to education in self-employment are found. These results are robust across different estimation methods: OLS; Heckit correction models to handle sample selection; and IV to deal with the potential endogeneity of years of schooling. Moreover, the results are insensitive to the use of different sample years, different definitions of self-employment, and different income measures for the self-employed.

Entrepreneurial Human Capital Iversen, Jens; Malchow-Møller, Nikolaj; Sørensen, Anders We argue that formal schooling and wage-work experience are complementary types of human capital for entrepreneurs. Strong empirical support is found for this hypothesis as the interaction term between schooling and actual wage-work experience enters positively and significantly in a Mincer equation, whereas the effect of schooling in the absence of wage-work experience is insignificant. These results are extremely robust towards more flexible specifications, including fixed-effects estimations dealing with unobserved heterogeneity. For wage workers, the interaction term is negligible, confirming that the complementarity is a distinct characteristic of entrepreneurial human capital.

Do Human Arts Really Offer a Lower Return to Education? Dalgaard, Carl-Johan; Schultz, Esben Anton; Sørensen, Anders Is the wage gap between majors in human arts and other fields caused by the education? If the educational choice is endogenous, the wage gap may instead be caused by selection. We document that individuals’ educational choice is correlated with that of older students and by the concentration of women in their high school. Conditional on high school fixed effects, these characteristics are unlikely to affect post-university wages and are plausible instruments for the educational choice. Our 2SLS estimates reveal that the gap in returns to education is negligible, implying that the wage gap is attributable to selection.

Comment on education returns of wage earners and self-employed workers Poutvaara, Panu; Tuomala, Juha; Jordahl, Henrik In a recent paper, García-Mainar and Montuenga-Gómez [Econ. Edu. Rev. 24 (2005)] apply the generalized IV model of Hausman and Taylor to estimate education returns of wage earners and the self-employed in Portugal and in Spain. Our examination reveals several problems which relate to the validity and documentation of the instrumental variables, as well as the robustness of the results.
