We model trade policy as a Markov process. Using a dynamic exporting model, we estimate how expectations about U.S. tariffs on China have changed around the U.S.-China trade war. We find (i) no increase in the likelihood of a trade war before 2018; (ii) the trade war was initially expected to end quickly but its expected duration grew substantially after 2020; and (iii) the trade war reduced the likelihood that China would face Non-Normal Trade Relations tariffs in the future. Our findings imply the expected mean future U.S. tariff on China rose more under President Biden than under President Trump.
