Role Models or Individual Consulting: The Impact of Personalizing Micro-entrepreneurship Training
在智利的随机实验中，研究发现培训项目中安排成功校友作为榜样，能显著提高微型创业者一年后的家庭收入，效果与个性化咨询相当但成本更低，尤其适合经验不足的企业。
Using a randomized experiment in Chile, we study the impact role models have in the context of a training program for micro–entrepreneurs. We show that being in a group randomly chosen to be visited by a successful alumnus of the program increases household income one year after, mostly due to increased business participation and business income. We also randomized the provision of personalized “consulting sessions” vis–à–vis group sessions, and observe similar effects on income, with the role model intervention being significantly more cost-effective and better suited for less experienced businesses.
