We directly compare two promising approaches to increasing sustainable entrepreneurship among young women: a multifaceted entrepreneurship promotion program and a comparably valued unconditional cash grant. Both interventions increased entrepreneurship in the long-term and increased income in the medium-term, but impacts on income do not persist in the long-term. The higher cost of the multifaceted program arm and the similarity of impacts across the two treatments indicates that the cash grants are a more cost effective way of increasing entrepreneurship in this context. The lack of sustained impacts on income suggests that self-employment may not be the solution to high youth underemployment.
