and much less sophisticated econometric treatment. Therefore, in this section, I simply focus on results in the literature on the proportion of entrepreneurs by educational attainment. In Section 5, I supplement this with further, new evidence from the NLSY79. In that section, I also go beyond the focus on schooling in much of the entrepreneurship literature and consider another, potentially more informative proxy for ability: wages in previous employment. Results from the NLSY79 are generally in line with the ones from other countries and data sources reported in this section.
