Additional years of education lead to higher rates of entrepreneurship and self-employment, according to a new study from Iowa State University economics professor John Winters and graduate student Kunwon Ahn. The study, which was published in Small Business Economics, shows that “an additional year of schooling increases self-employment in high-growth industries by 1.12 percentage points for women and by 0.88 percentage points for men.” To sum it up, “the results suggest that formal education enhances entrepreneurship,” the paper says.
