Trade Protection, Stock Market Returns and Welfare
Abstract
Tariff announcements made during the U.S.-China trade war had broad effects on financial variables. Announcements systematically decreased stock prices and raised nominal and real bond prices. We use a specific factors model to show that the welfare impact of the tariffs can be identified from the policy-induced movement in the present value of firm cash flows: a variable that can be estimated from financial data. Using this framework, we find that the U.S.-China trade war lowered U.S. welfare by three percent. We show that these cash flow movements can be further decomposed into market expectations about how tariffs affect current and future prices and productivity. Seen through the lens of our model, the market reactions to tariff announcements can be explained by expectations that tariffs lead to large, negative future priceand TFP shocks that play an important role in dynamic, but not static, models.
