Abstract
Microfinance institutions have started to bundle their basic loans with other financial services, such as health insurance. Using a randomized control trial in Karnataka, India, this project evaluates the impact of mandating the purchase of actuarially-fair health insurance covering hospitalization and maternity expenses on health and financial outcomes.

As bundling loans with insurance led to a decline in the renewal of microfinance loans, with many clients preferring to give up microfinance than to pay higher interest rates and receive insurance, we also examine the effects of non-renewal.

Experimental Design
Experimental Design
In June 2007, SKS Microfinance, which at the time was the largest MFI in India, began to require clients in 101 villages to purchase health insurance at the time of renewing loans. The 101 villages were selected randomly from a list of 201 candidate villages. Clients in the remaining 100 villages were not offered or required to purchase health insurance from SKS. The random selection of villages into the treatment group allows for the identification of causal effects of the insurance requirement by comparing outcomes between the selected and not selected.

We collected detailed baseline data on a random sample of SKS client households in treatment and control villages prior to the intervention. This baseline survey was complemented by a survey of major health events among clients during the intervention and an endline survey after the intervention ended and the purchase of insurance was no longer mandatory. In addition to survey data, we received detailed administrative data from SKS on clients' loan history and health insurance usage.
