Data and Code for "Propagation and Insurance in Village Networks"

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.

发展中国家的企业嵌入于供应链与劳动力网络之中。这些关联可能传导或削弱冲击。借助泰国乡村的面板数据，我们记录了三个事实：当遭遇异质性冲击的家庭调整其生产活动时，此类冲击会在生产与消费层面传导至其他家庭；通过劳动力渠道的传导效应强于供应链渠道；在更密集的网络中发生的冲击，以及对更核心家庭的冲击，其传导范围更广；而获得正式或非正式保险则会减弱传导效应。扩大安全网所带来的社会收益可能高于私人收益。
