题目：The Causal Impact of the 2018 Tariff Shock on US Firms: Does Artificial Intelligence Mitigate Tariff-Induced Losses?

报告人：Sushanta Mallick

摘要： This paper examines the impact of the 2018 US tariff escalation on firm profitability and investigates whether artificial intelligence (AI) adoption enhanced firms' resilience to tariff-induced shocks. Using a difference-in-differences framework, we compare firms importing intermediate inputs with those importing final consumption goods to identify the causal effect of tariffs on profitability. We construct a firm-level measure of AI adoption from textual analysis of SEC 10-K filings, capturing firms' investments in and use of AI technologies. We then estimate a triple-difference model to assess whether AI-adopting firms were better able to withstand the adverse effects of tariffs. The results show that the 2018 tariff shock significantly reduced the profitability of intermediate-input importers relative to firms importing final goods. However, AI adoption partially offset these losses, with AI-intensive firms experiencing a significantly smaller decline in profitability. These findings suggest that AI can strengthen firms' resilience to trade policy shocks, although it cannot fully eliminate their adverse effects.
