Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

We test whether managerial human capital has a first order effect on the performance and growth of small enterprises in emerging markets. In a randomized control trial in Puebla, Mexico, we randomly assigned 150 out of 432 small and medium size enterprises to receive subsidized consulting...
