Few studies have rigorously quantified the impacts of microcredit loans or determined the sensitivity of borrowers to interest rate pricing. In cooperation with the Peruvian microfinance institution ARARIWA, IPA is investigating the impact of microloans on the whole as well as determining the demand curve for microcredit.

For the study, areas in Cuzco are divided into one of three groups: a control group with no access to credit during the 24 months of the study, a treatment group that will receive credit offers at a lower interest rate, and treatment group that will receive credit offers at a higher interest rate. Data is being collected to analyze the take-up of microcredit loans, changes in socioeconomic levels, and borrower sensitivity of interest rates.
