Experimental Design Details
Do payday loans harm borrowers by exploiting behavioral biases? We examine whether and why borrowers fall into “debt traps” -- failing to anticipate future borrowing and its costs -- by eliciting forecasts and commitment valuations from current borrowers in partnership with a large payday lender and then tracking borrowing behavior with administrative data. Our baseline survey asks borrowers to forecast their borrowing behavior over the next several months, and also gives them incentivized between an unconditional cash transfer and one that is contingent on not taking out a loan.
We plan to use the data in several ways. First, we will estimate borrower forecast biases and commitment valuations. Second, we will use the randomized incentives to estimate the price elasticity of demand for payday loans. Third, we will estimate present-bias and sophistication parameters from a beta-delta model. Fourth, we plan to input those parameter estimates into a calibrated model of consumption, savings, and borrowing and use it to simulate the welfare effects of popular regulatory approaches.
