The Indirect Effects of Hurricanes: Evidence from Firm Internal Networks


Abstract: Are the effects of hurricanes spatially mitigated or propagated by firms through their internal network of establishments? This paper quantifies the indirect spatial impacts of hurricanes by examining linkages that arise between disrupted and undisrupted regions via plant ties within firms. For a typical county hit by a hurricane in the United States, for every manufacturing job lost upon exposure, I estimate that an additional 0.19 to 0.25 manufacturing jobs are lost across undisrupted distant regions due to spatial propagation within multi-plant firms. The spatial propagation is consistent with mechanisms of resource-constraints and managerial distraction within the firm. Overall, the results indicate that we potentially underestimate the effects of hurricanes by ignoring inter-regional linkages emerging from firms’ internal networks.
