"A randomized control trial with 432 small and medium enterprises in Mexico shows positive impact of access to 1 year of management consulting services on total factor productivity and return on assets. Owners also had an increase in "entrepreneurial spirit" (an index that measures entrepreneurial confidence and goal setting). Using Mexican social security data, we find a persistent large increase (about 50 percent) in the number of employees and total wage bill even 5 years after the program. We document large heterogeneity in the specific managerial practices that improved as a result of the consulting, with the most prominent being marketing, financial accounting, and long-term business planning."

"We design a randomized controlled trial to evaluate the adoption of credit scoring with a bank that uses soft information in small businesses lending. We find that credit scores improve the productivity of credit committees, reduce managerial involvement in the loan approval process, and increase the profitability of lending.

Credit committee members' effort and output also increase when they anticipate the score becoming available, indicating that scores improve incentives to use existing information. Our results imply that credit scores improve the efficiency and decentralize decision-making in loan production, which has implications for the optimal organization of banks."

"This paper documents that ventures that are funded by two successful angel groups experience superior outcomes to rejected ventures: they have improved survival, exits, employment, patenting, web traffic, and financing. We use strong discontinuities in angel funding behavior over small changes in their collective interest levels to implement a regression discontinuity approach. We confirm the positive effects for venture operations, with qualitative support for a higher likelihood of successful exits. On the other hand, there is no difference in access to additional financing around the discontinuity. This might suggest that financing is not a central input of angel groups."

"Small and medium enterprises (SMEs) are thought to be important drivers of growth in developing economies, but entrepreneurs in these countries face many barriers, including poor access to training, finance, and business networks. In Colombia, Fundación Bavaria's "Destapa Futuro" (Open the Future) program identifies promising enterprises and provides them with a suite of financial, technical, business, and training resources. Researchers found that the trainings did not affect key business outcomes, such as sales and profits, but helped entrepreneurs to expand their business networks."
