Abstract
This field experiment randomized access to Self-Help Groups in villages spread over the entire state of Jharkhand and surveyed a sample of 1,080 households three times between 2004 and 2009, in order to evaluate the changes in their living standards. We study impacts on children education and labor, household consumption and risk-coping behavior (including migration), and local credit markets.

Experimental Details
Interventions
Intervention(s)
Indian Self-Help Groups are informal groups of villagers (often women) with homogeneous background, who voluntarily come together to save and borrow small amounts on a regular basis. They represent the dominant microfinance model in India, and one of the world's largest and most sustainable.

Experimental Design
Experimental Design
The NGO PRADAN established a list of potential intervention villages (based on their high poverty incidence), located in four geographic clusters covering the entire state of Jharkhand. Among that list, 24 villages were randomly selected to launch PRADAN's SHG program between April and June 2002, and 12 other villages from the same districts were kept as the control group.
In treated villages, the program was explained in public village meetings, and groups of between 10 and 20 interested women were formed (one important rule imposed by PRADAN is that there may be only one member per household). By January 2004, there were between 1 and 10 active SHGs (4 on average) in treated villages and none in control villages.
