This blog series highlights the randomized trial of the impact of Compartamos, a for-profit microlender in Mexico, and their expansion in the Nogales area. The questions came from the original post here.

Outcome measure: Is there substitution between use of Compartamos (Crédito Mujer) and informal lending/savings mechanisms?

We are nearing completion of a randomized trial of the impact of Compartamos, a for-profit microlender in Mexico, and their expansion in the Nogales area. We will be posting our hypothesis before we do the analysis, and encourage readers to do the same, for three reasons:

At Academy Award parties on Sunday across the country, people filled out sample ballots to guess the Oscar winners before they were announced. Now we’re doing the same thing. We’ve got a new challenge for all you blog readers out there: predict the results of our studies.

Politicians are ignorant about trials, and they're weird about evidence. It doesn't need to be this way. In international development work, resources are tight and people know that good intentions aren't enough: in fact, good intentions can sometimes do harm. We need to know what works.

The emerging answer seems to be similar to the answer to the question: "Does Aid Work?": It depends.

We just finished up the first panel session at Microfinance Impact 2010, moderated by Jonathan Morduch, and with presentations by Dean Karlan (Yale and IPA), Abhijit Banerjee (MIT), Esther Duflo (MIT), Carlos Danel (Compartamos Banco) and Tanguy Bernard (Agence Française de Développement).

This seems to be our week to blog about Bill Easterly's blog.  Although in this one, we aren't going to agree as much.  I was really excited to see his report about Women's Trust until I got to the final paragraph:

Dean Karlan and Jonathan Zinman provide insight into the effects of expanded access to credit with findings from a South Africa study, whereby a lender offered loans to individuals who had previously been narrowly rejected for loans. The results: the lender saw some profits, and borrowers had more food on the table, better job retention, more spending on transportation to get to work, and a boost in credit ratings.
