The Interplay Among Savings Accounts and Network-Based Financial Arrangements: Evidence from a Field Experiment
通过尼泊尔村庄的实地实验，研究发现获得储蓄账户的家庭增加了对其他家庭的贷款和总转账，无论对方是否也获得账户，且这一效应主要由基线时资产较多、金融包容度较高的家庭驱动。
Abstract This paper studies how formal financial access affects network-based financial arrangements. We use a field experiment that granted access to a savings account to a random subset of households in 19 Nepalese villages. Exploiting a unique panel dataset that follows all bilateral informal financial transactions before and after the intervention, we show that households that were offered access to an account increased their loans and total transfers to others, independent of the treatment status of the receiver. The increase seemed to be driven by treatment households with more assets and greater financial inclusion at baseline.
