Managers' Inventory Holding Decisions in Response to Natural Disasters

ABSTRACT We study how firms' inventory holdings are affected by natural disasters. Building on the premise that managers often make decisions in line with the availability heuristic, we investigate whether managers increase inventory holdings in response to heightened disaster risk perceptions and the need to hedge against inventory shortages. Through a battery of tests, we show that the occurrence of disasters in neighboring counties triggers inventory stockpiling, an effect that is unlikely to be driven by the real disaster disruptions. Our results also indicate that inventory stockpiling is likely inconsistent with a rational expectations equilibrium. Collectively, our results highlight another undesirable consequence of natural disasters and warn about supply chain implications due to increased climate ambiguity.
