Abstract: This study investigates how managers' perceived trade policy uncertainty (TPU) affects firms' cost management decisions. Adopting a firm‐level TPU measure developed by a large language model, our analysis reveals that TPU reduces cost stickiness. This effect is more pronounced in firms managed by non‐overconfident, risk‐averse, or high‐ability executives. Our results hold when we employ a series of endogeneity tests, including a coarsened exact matching method, a difference‐in‐difference approach, and an instrumental variable approach. Finally, we find that firms' cost management decisions resulting from pessimistic expectations about future sales have significant implications for firm performance.
