摘要:Gifts are important instruments to bond interpersonal relationships. Using 36 million online red packets on WeChat, we employ a natural experiment approach to identify in-group contagion of gift giving. We find that, on average, receiving one more dollar causes a recipient to send 18 cents back to the group within the subsequent 24 hours. Moreover, this effect is much stronger for "luckiest draw'' recipients, which suggests a group norm for gift giving. Additionally, we find that gift contagion is affected by in-group friendship network properties, such as the number of in-group friends and the local clustering coefficient.
