Propagation and Insurance in Village Networks
利用泰国村庄面板数据,研究家庭生产调整如何通过供应链和劳动网络传播冲击,发现劳动网络传播效应更强,且保险可减缓传播,提示扩大安全网的社会收益可能高于私人收益。
Firms in developing countries are embedded in supply chains and labor networks. These linkages may propagate or attenuate shocks. Using panel data from Thai villages, we document three facts: as households facing idiosyncratic shocks adjust their production, these shocks propagate to other households on both the production and consumption sides; propagation is greater via labor than supply chain links; and shocks in denser networks and to more central households propagate more, while access to formal or informal insurance reduces propagation. Social benefits from expanding safety nets may be higher than private benefits.
