"Do business accelerators add value? If so, how? We investigate these questions by focusing on Start-Up Chile, a government-backed ecosystem accelerator. Using a regression discontinuity design, we show that entrepreneurship-schooling services of accelerators can significantly increase new venture performance by improving the entrepreneurial capital of participants. We speculate about the existence of four performance-enhancing mechanisms: greater social clout, the provision of an accountability structure that induces entrepreneurs to articulate and reflect about specific strategic tasks, an increase in self-efficacy, and know-how about building a start-up. We find no support for causal effects of basic services of cash and co-working space."

"Management has a large effect on the productivity of medium and large firms. But does management matter in micro and small firms, where the majority of the labor force in developing countries works? We develop 26 questions that measure business practices in marketing, stock-keeping, record-keeping, and financial planning. These questions have been administered in surveys in Bangladesh, Chile, Ghana, Kenya, Mexico, Nigeria, and Sri Lanka. We show that variation in business practices explains as much of the variation in outcomes-sales, profits, and labor productivity and total factor productivity-in microenterprises as in larger enterprises."
