Abstract
While the universal policy of gender targeting in microfinance stems, inter alia, from the conventional wisdom that women are better credit risks, there has been little research on the underlying reasons for it. This study aims to contribute to that research gap by conducting microfinance lab-in-the-field or artefactual field experiments in comparable matrilineal and patrilineal societies in rural India to exploit the natural variation in social norms across these societies.

Experimental Details
Interventions
Intervention(s)
The intervention is a microfinance 'lab-in-the-field' or artefactual field experiment that is conducted with the matrilineal Khasi society in Meghlaya and two patrilineal societies in the neighbouring states of Assam and West Bengal.

Primary Outcomes
Primary Outcomes (end points)
Loan Default
Project Choice
Repayment Choice (Strategic Default)
Primary Outcomes (explanation)
Loan default measures whether an individual or a group defaulted on the loans given to them during the microfinance experiment. Project choice indicates whether they invested the loan in the relatively safer or the riskier project during the experiment. Finally, repayment choice (strategic default) indicates whether they repaid or strategically defaulted on their loans if their chosen project was successful in the experiment.
Secondary Outcomes
Secondary Outcomes (end points)
Amount invested in the lottery
Secondary Outcomes (explanation)
The amount invested in the lottery measures the subjects' risk attitudes. The lower the amount invested, the more risk-averse subjects are.
Experimental Design
Experimental Design
The experimental design incorporates two treatments- individual and group liability game treatment. In the individual game, each person receives a loan and decides to invest it between a relatively safer project with a lower return and a riskier project with a higher return. If the chosen project is successful, the individual decides to repay her loan or to default strategically. In the group liability games, two individuals of the same gender are randomly matched and are liable for each other's loans. It means that both group members are liable if any one group member defaults. In the experiment, each group member receives a loan and decides independently to invest it between a relatively safer project and a riskier project, same as that in the individual game. If the project is successful, which is private information to the individual group members, they decide independently to contribute to the group repayment or default strategically. The experimental design also incorporates an investment risk (IR) task. In the IR task, subjects decide how much of their endowment to invest in a lottery that returns three times the amount invested or zero with equal probabilities.
Experimental Design Details
Randomization Method
Subjects are randomized into one of the two treatments-individual or group liability game treatment. The randomization was done using a computer.
Randomization Unit
The unit of randomization is a subject who participated in the experiment.
Was the treatment clustered?
No
