Microcredit has become a buzzword over the past couple of decades and many have hoped that small loans would help microenterprises grow and raise the incomes of their owners. Recently, a number of rigorous studies have measured the effect of credit on microenterprises. The results paint a nuanced picture; with most studies showing no strong impact on microenterprise growth (see Chapter 3 of the World Bank Group’s Global Financial Development Report 2014 for a summary of these findings).
Researches have uncovered several reasons why microcredit may not lead to the expected increase in firm growth. For example, to mitigate default risk, microloans often have joint liability. However, joint liability may discourage investment because group members have to pay more if a fellow borrower makes a risky investment that goes bad, but they do not enjoy a share of the profits if the investment yields returns. Also, looking beyond microcredit, recent studies suggest that providing other financial instruments, such as savings products and microinsurance, can spur microenterprise investment and growth.
