The Information Value of Online Social Networks: Lessons from Peer-to-Peer Lending

Working Paper: NBER ID: w19820

Authors: Seth Freedman; Ginger Zhe Jin

Abstract: We examine whether social networks facilitate online markets using data from a leading peer-to-peer lending website. We find that borrowers with social ties are consistently more likely to have their loans funded and receive lower interest rates; however, most borrowers with social ties are more likely to pay late or default. We provide evidence that these findings are driven by lenders not fully understanding the relationship between social ties and unobserved borrower quality. Overall, our findings suggest caution for using online social networks as a signal of quality in anonymous transactions.
