A beginner’s guide to tariffs: Why are they harmful?

Trump is using tariffs as his main international economic policy tool and is providing two conflicting narratives on why he is using them. On the one hand, he suggests that raising tariffs is the key to making America wealthy again: the US government will supposedly raise trillions in tariff revenue, manufacturing production and jobs will move back to the US, and the US trade deficit will finally shrink. On the other hand, tariffs are an instrument to bring countries to the table and negotiate a deal.[1] Yet, of the two narratives, only one can stand. To bring back jobs and reduce the deficit, tariffs must be permanent. If they are a negotiating tool, they must be temporary. Leaving behind the motivations for the tariff increases, economists tend to disagree that raising tariffs will make America wealthier. Ever since the first round of tariffs on Canada and Mexico was announced, experts have warned about the negative consequences: prices for US consumers will increase, fewer products will be available, exports will fall, and economic activity (GDP) will contract. And this is just for the US. Since the US is a large market with the power to affect world demand and prices, the [...]

The real Donald Trump: A free trader in protectionist clothing or vice versa?

This blog was originally published in 2018. We are republishing now because it is striking how much of its analysis and assessment of President Trump’s approach to trade and tariffs resonates today. Importantly, looking back in this way helps to give a longer run historical perspective on the Trump approach to trade policy, which may also help to shape thinking about the future, and responses to that future. Note from the author: In 2018, I described the tug-of-war between the mercantilist and Reaganite factions of the Republican party as the key to understanding the trade policy fluctuations of Trump's first term. This time around, the mercantilists have clearly won. The explicit tying of Trump's "reciprocal" tariffs to U.S. bilateral trade deficits, along with a baseline ten percent tariff, indicates that trade deals alone are not the goal. Trump wants to end trade deficits, pursue import substitution in manufacturing and bring back a 19th century tax system based on customs revenue. These are disastrous goals in themselves; moreover, nothing America's trading partners can do with their own trade policies can satisfy them. This is why the markets have melted down. Perhaps as the effects take hold in the real economy, Trump [...]

Blinded by the light: The trouble with today’s trade policy

Trade policy is more difficult today that it was three months ago, and significantly more so than five years ago. The former is due to the actions of the new US administration, but the latter is a more complicated story that has dramatically changed trade policy across the world. Over the last 30 years or so trade policymakers have largely focused on efficiency gains - more open markets leading to better productivity and economic growth. This was more or less taken for granted, backed by considerable evidence. The distributional implications and broader concerns beyond economic growth have been seen as beyond the purview of trade policy, perhaps too easily. Once again, trade policy makers and analysts either took for granted that these issues were not so important in the trade context, or if they were, they would be dealt with by other areas of government policy. However, in today’s world even efficiency and equity considerations fail to adequately capture the concerns of trade policy. Unforeseen events – Covid-19, the Russian invasion of Ukraine, extreme weather, and semi foreseen events such as Trump tariffs – have underpinned increasing concerns about economic security, supply chain resilience and national security, and the threats [...]

What’s wrong with the USTR analysis of worldwide protection?

The analysis by the office of the US Trade Representative (USTR) that accompanies President Trump’s tariff announcement on 2 April is so profoundly wrong that one might (almost) feel sorry for the USTR staffers tasked with putting academic lipstick on a wayward pig. Their central argument is that one can measure how protectionist a country’s trade policies are by the size of its trade surplus in goods with the United States. Vietnam is judged to be highly protectionist because it exports to the USA much more than it imports. It is a relatively poor developing country with a competitive advantage in low-paying manufactures (such as clothing) which the US largely abandoned decades ago. It also has little appetite for the kinds of goods and services that the US exports. Vietnam’s trade with the US is not the result of protectionism. The EU, which retains a strong manufacturing sector in Germany, and has a significant surplus with the US, is judged to be more protectionist than the UK, whose competitive advantage is stronger in services. The reality is that despite Brexit, there is little difference between the trade policies of the UK and the EU. The USA runs a trade deficit [...]
