Growing Markets through Business Training for Female Entrepreneurs: A Market-Level Randomized Experiment in Kenya
在肯尼亚进行的两阶段随机实验表明，对部分小企业提供商业培训后，受助企业销售额和利润提升，但未显著损害未受助竞争者，整个市场销售额反而增长。
A common concern with efforts to directly help some small businesses to grow is that their growth comes at the expense of their unassisted competitors. We test this possibility using a two-stage randomized experiment in Kenya that randomizes business training at the market level and then within markets to selected businesses. Three years after training, the treated businesses are selling more, earn higher profits, and their owners have higher well-being. Point estimates of the spillovers on the competing businesses are small and not statistically significant, and the markets as a whole have grown in terms of sales volume.
