简介：

We examine how early-life disaster experiences shape households’ social network formation. Using the 2017 China Household Finance Survey and a famine severity index derived from exogenous weather shocks during China’s Great Famine, we implement a difference-in-differences strategy combining birth cohorts with county-level variation in famine intensity. We find that individuals exposed to famine in childhood or adolescence spend significantly more on gifts to strengthen social networks. Mechanism analysis shows that the effect is particularly pronounced for households facing higher perceived risks, in regions characterized by underdeveloped financial markets and more initial social capital, suggesting that heightened risk perception—rather than background risks—links famine experiences to later-life network formation. Our findings underscore the long-lasting role of early-life traumatic experiences in shaping households’ risk-management behavior.
