在一个非正式网络内汇集资源，可以提供防范特殊风险的保险和流动性，以进行高回报但有利可图的投资。这个网络的存在可能会给其成员带来长期的消费收益。我们利用墨西哥农村506个贫困村庄的人口普查中的姓氏信息来确定家庭是否在村里有一级亲属，从而将这些想法应用于数据。使用外生收入变化和面板数据，我们发现，家庭与一级亲属在村里（或“连接”的家庭）池内的大家庭的资源，但不与家庭没有一级亲属在村里（或“孤立”的家庭）。我们发现，联系紧密的家庭可以有效地相互分担风险，而且同样的正收入冲击对联系紧密的家庭和孤立的家庭的影响有所不同：联系紧密的家庭在孩子的人力资本上投资更多，这是一项高回报的投资，而在家禽上投资较少，这是一项低回报的投资。在这一收入冲击五年后，联网家庭的消费更高，尽管基线时与孤立家庭的消费相同。
Pooling resources within an informal network may provide insurance against idiosyncratic risk and liquidity to undertake high-return but lumpy investment. The presence of this network may cause longterm consumption gains to its members. We take these ideas to the data by exploiting the information on surnames from a census of 506 poor villages in rural Mexico to identify whether households have first-degree relatives in the village. Using exogenous income variation and panel data, we show that households with first-degree relatives in the village (or ‘connected’ households) pool resources within their extended families but not with households without first-degree relatives in the village (or ‘isolated’ households). We find that connected households efficiently share risk with each other and that the effect of the same positive income shock differs for connected and isolated households: connected households invest more in their children’s human capital, a high-return investment, and less in poultry, a low return investment. Five years after this income shock, consumption is higher for connected households, despite having the same consumption as isolated households at baseline.
