"A randomized control trial with 945 entrepreneurs in Jamaica shows positive short-term impacts of soft-skills training on business outcomes. The effects are
concentrated among men, and disappear twelve months after the training. We argue that the main channel is increased adoption of recommended business practices, exclusively observed in the short run. We see persistent effects on an incentivized behavioral measure of perseverance after setbacks, a focus of this training. We compare a course focused only on soft-skills to one that combines soft-skills training with traditional business training. The effects of the combined training are never statistically significant."

"This paper evaluates the impact of the Chilean Supplier Development Program, aimed at improving and stabilizing the commercial linkages between small and medium-sized suppliers and their large firm customers, during the period 2003-2008. Applying propensity score matching and difference-in-differences, we find that both groups of firms benefited from the coordination efforts. The program increased sales, employment, and the sustainability of small and medium-sized suppliers. It also increased the sales of large firms and raised their ability of becoming exporters. We also find that the timing of the effect is different for suppliers and large firms. While the effect on suppliers appeared one year after the firms enrolled in the program, the effect on large firms took two years to appear."
