Interpersonal versus interbank lending networks

Abstract

Analyzing the interpersonal lending network of a Hungarian village in a disadvantaged region, we find strong intermediary activity and a tiered core-periphery structure. We show that the main motive behind lending is not altruism or profit-seeking, but risk-sharing which is the most accentuated in poor-to-poor and Roma-to-Roma relations. Comparing this informal lending market to a formal interbank market, we find more similarities than differences. In both markets, intermediation is a key element in risk-sharing and an effective tool to cope with liquidity risk. Regulatory and development policies should respect the existing institutions of risk-sharing.
