As frequently voiced complaint from the Trump administration was that US firms have faced a competitive disadvantage in exports because the US market is open and US tariffs are low but US trading partners protect their markets with high tariffs. The administration used this concern to justify raising US tariffs whenever it could. Lawrence argues that these claims should be more nuanced and account for the extensive unilateral liberalization by many countries over the past 30 years and that the grievances that motivated the Trump trade policies are increasingly misplaced. Many developing countries have reduced their tariffs unilaterally to rates that are far lower than they applied three decades ago and far less than the bound rates reflected in their World Trade Organization (WTO) obligations. Globally, on average, tariffs were not raised during the global financial crisis of 2008 and continued to decline through at least 2018. Even when shocks from imports resulted in serious injury to domestic industries, several developing countries temporarily provided safeguard protection but at levels that were lower than their WTO bound rates. This evidence of import liberalization also suggests that rising protectionism was not responsible for the slow growth in world trade that has been evident since 2011. It remains uncertain whether countries will now respond to disruptions to global supply chains since 2018 caused by Trump’s trade policies and the COVID-19 pandemic by reversing their tariff liberalization stance, but the sustained enthusiasm for new megaregional trade agreements suggests many countries will not.
