典当贷款为借款人提供了极大的还款灵活性，但违约时需承受严厉惩罚：不仅要没收价值超过贷款金额的抵押物，还要丧失所有已支付的还款款项。本文利用在墨西哥城开展的一项大型随机对照试验（RCT），梳理了典当贷款的关键典型事实，并探讨在这一重要却研究不足的信贷形式中，用结构化还款合同取代灵活性的可行性。本实验设计包含三个组别：强制频繁还款组、（现状）灵活还款组，以及可在两者间自主选择的组别。该设计不仅能识别平均处理效应，还能识别处理对已处理者、未处理者的效应，以及平均收益选择效应，从而严谨地研究强制要求与选择的差异。尽管将借款人分配至结构化还款的平均处理效应为其财务成本降低19%、违约概率降低17.5%，但仅有11%的借款人会自愿选择结构化还款合同。研究表明，结构化还款几乎能为所有借款人降低财务成本，包括那些不会自主选择它的借款人，且未发现成本节约存在收益选择效应的证据。
英文摘要
Pawn loans offer borrowers a substantial degree of repayment flexibility in exchange for a harsh penalty in case of default: forfeit of collateral worth more than the loan amount along with any payments made toward recovery. Using a large RCT conducted in Mexico City, we document key stylized facts about pawn lending and explore the merits of replacing flexibility with structured repayment contracts in this important but understudied form of credit. Our experimental design includes a mandatory frequent-payments arm, a (status quo) flexible payments arm, and a choice between the two. This design point-identifies not only the average treatment effect, but also the effects of treatment on the treated and the untreated along with the average selection on gains, allowing a rigorous study of mandates versus choice. Although the average treatment effect of assigning borrowers to structured payments is a 19% decrease in their financial cost and a 17.5% decrease in the probability of default, only 11% of borrowers choose structured repayment contracts voluntarily. We show that structured repayment reduces financial costs for nearly all borrowers, including those who would not freely choose it, and find no evidence of selection on gains in cost savings.
