Feng's article quantitatively analyzes the impact of tariffs on US prices from a data perspective. The conclusion is that a 10% increase in tariffs on all imported goods from China has an impact of 0.276% on US prices, which is approximately equivalent to a one month lag in CPI decline. The impact is not significant. Imposing comprehensive tariffs on Canada and Mexico may have a greater impact on US prices, as the US imports a large amount of goods from these two countries.
