| Abstract: | 
This paper presents short-term results from an experiment randomizing the 
promotion and registration of a mobile savings account among women 
microentrepreneurs in Tanzania, with and without business training. Six months 
post-intervention, the results show that women save substantially more through 
the mobile account, and that the business training bolstered this effect. 
Women also obtain more microloans through the mobile account, an additional 
service provided by the product. The business training further led to an 
increase in the business practices of the women. We find no significant 
evidence that these impacts translate into greater investment, sales, and 
profits, but we see some evidence of increased business expansion through the 
creation of profitable secondary businesses, as well as improvements in 
women’s empowerment and subjective well-being. |
