Abstract：In this paper, we take Hurricane Sandy that hit the east coast of the United States in 2012 as a source of exogenous negative shocks and examine its indirect effects on the global economy through supply chains. More specifically, using firm-level data on global supply chains, we examine how sales growth of firms in and outside the US changes when their suppliers or customers are damaged by the hurricane. Our results show that in most cases the negative effect on transaction partners outside the US and the effect on firms in the US show different features, concluding that national border matters to the size of propagation of negative shocks by the hurricane through global supply chains. We further find that the negative effect is heterogeneous in size across firms depending on the level of globalization of each firm, existence of other networks, and the density of each firm's ego-network.
