"Does the lack of peers contribute to the observed gender gap in entrepreneurial success? A random sample of customers of India's largest women's bank was offered two days of business counseling, and a random subsample was invited to attend with a friend. The intervention significantly increased participants' business activity, but only if they were trained with a friend. Those trained with a friend were more likely to have taken out business loans, were less likely to be housewives, and reported increased business activity and higher household income, with stronger impacts among women subject to social norms that restrict female mobility."

"Theories of market failures and targeting motivate the promotion of entrepreneurship training programs and generate testable predictions regarding heterogeneous treatment effects from such programs. Using a large randomized evaluation in the United States, we find no strong or lasting effects on those most likely to face credit or human capital constraints, or labor market discrimination. We do find a short-run effect on business ownership for those unemployed at baseline, but this dissipates at longer horizons. Treatment effects on the full sample are also short-term and limited in scope: we do not find effects on business sales, earnings, or employees."
