Policy uncertainty and inventory behavior: Evidence from the US manufacturing sector

Abstract

This study investigates the impact of economic policy uncertainty (EPU) on asymmetric inventory investment (i.e., inventory stickiness or sticky inventory management). Using a sample of 74,912 US firm-year observations over the 1984–2021 period, we observe a significantly negative relationship between EPU and asymmetric inventory investment. Our cross-sectional analyses reveal that managers' pessimistic expectations regarding future demand and higher cost of funding and maintaining capacity are the channels through which EPU affects asymmetric inventory behavior. Moreover, this negative impact is more pronounced for firms that face longer-duration uncertainty, rely heavily on government purchases, and have higher firm-specific political risk. Lastly, we find that reducing inventory stickiness leads to improved firm performance during periods of increasing policy uncertainty.
