We study the macroeconomic consequences of tariffs. We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. We find that tariff increases lead, in the medium term, to economically and statistically significant declines in domestic output and productivity. Tariff increases also result in more unemployment, higher inequality, and real exchange rate appreciation, but only small effects on the trade balance. The effects on output and productivity tend to be magnified when tariffs rise during expansions, for advanced economies, and when tariffs go up, not down. Our results are robust to a large number of perturbations to our methodology, and we complement our analysis with industry-level data.

We study the robustness of the Lerner symmetry result in an open economy New Keynesian model with price rigidities. While the Lerner symmetry result of no real effects of a combined import tariff and export subsidy holds up approximately for a number of alternative assumptions, we obtain quantitatively important long-term deviations under complete international asset markets. Direct pass-through of tariffs and subsidies to prices and slow exchange rate adjustment can also generate significant short-term deviations from Lerner. Finally, we quantify the macroeconomic costs of a trade war and find that they can be substantial, with permanently lower income and trade volumes. However, a fully symmetric retaliation to a unilaterally imposed border adjustment tax can prevent any real or nominal effects.

A Foreign Affairs Best Book of the Year: “Tells the history of American trade policy . . . [A] grand narrative [that] also debunks trade-policy myths.” —Economist Should the United States be open to commerce with other countries, or should it protect domestic industries from foreign competition? This question has been the source of bitter political conflict throughout American history. Such conflict was inevitable, James Madison argued in the Federalist Papers, because trade policy involves clashing economic interests. The struggle between the winners and losers from trade has always been fierce because dollars and jobs are at stake: depending on what policy is chosen, some industries, farmers, and workers will prosper, while others will suffer. Douglas A. Irwin’s Clashing over Commerce is the most authoritative and comprehensive history of US trade policy to date, offering a clear picture of the various economic and political forces that have shaped it. From the start, trade policy divided the nation—first when Thomas Jefferson declared an embargo on all foreign trade and then when South Carolina threatened to secede from the Union over excessive taxes on imports. The Civil War saw a shift toward protectionism, which then came under constant political attack. Then, controversy over the Smoot-Hawley tariff during the Great Depression led to a policy shift toward freer trade, involving trade agreements that eventually produced the World Trade Organization. Irwin makes sense of this turbulent history by showing how different economic interests tend to be grouped geographically, meaning that every proposed policy change found ready champions and opponents in Congress. Deeply researched and rich with insight and detail, Clashing over Commerce provides valuable and enduring insights into US trade policy past and present. “Combines scholarly analysis with a historian’s eye for trends and colorful details . . . readable and illuminating, for the trade expert and for all Americans wanting a deeper understanding of America’s evolving role in the global economy.” —National Review “Magisterial.” —Foreign Affairs

Most trade is invoiced in very few currencies. Despite this, the Mundell-Fleming benchmark and its variants focus on pricing in the producer’s currency or in local currency. We model instead a ‘dominant currency paradigm’ for small open economies characterized by three features: pricing in a dominant currency; pricing complementarities, and imported input use in production. Under this paradigm: (a) the terms-of-trade is stable; (b) dominant currency exchange rate pass-through into export and import prices is high regardless of destination or origin of goods; (c) exchange rate pass-through of non-dominant currencies is small; (d) expenditure switching occurs mostly via imports, driven by the dollar exchange rate while exports respond weakly, if at all; (e) strengthening of the dominant currency relative to non-dominant ones can negatively impact global trade; (f) optimal monetary policy targets deviations from the law of one price arising from dominant currency fluctuations, in addition to the inflation and output gap. Using data from Colombia we document strong support for the dominant currency paradigm.

We estimate the macroeconomic effects of import tariffs and trade policy uncertainty in the United States, combining theory-consistent and narrative sign restrictions in Bayesian SVARs. We find mostly adverse consequences of protectionism, in aggregate and across sectors and regions. Tariff shocks are more important than trade policy uncertainty shocks. Tariff shocks depress trade, investment, and output persistently. The general equilibrium import elasticity is –0.8. Historically, NAFTA/WTO raised output by 1-3% for twenty years. Undoing the 2018/19 measures would raise output by 4% over three years. The findings imply higher gains of trade than partial equilibrium or static trade models.

Global Tariff War: Economic, Political and Social Implications traces the impacts that global tariff wars in international trade can have on the growth of national economies. Offering a range of perspectives from developing economies, this collection presents a unique insight into this complex area of geo-political and economic practice.

"This is a very important book."--Martin Wolf, Financial TimesA provocative look at how today's trade conflicts are caused by governments promoting the interests of elites at the expense of workers Longlisted for the 2020 Financial Times & McKinsey Business Book of the Year Award "Worth reading for [the authors'] insights into the history of trade and finance."--George Melloan, Wall Street Journal Trade disputes are usually understood as conflicts between countries with competing national interests, but as Matthew C. Klein and Michael Pettis show, they are often the unexpected result of domestic political choices to serve the interests of the rich at the expense of workers and ordinary retirees. Klein and Pettis trace the origins of today's trade wars to decisions made by politicians and business leaders in China, Europe, and the United States over the past thirty years. Across the world, the rich have prospered while workers can no longer afford to buy what they produce, have lost their jobs, or have been forced into higher levels of debt. In this thought-provoking challenge to mainstream views, the authors provide a cohesive narrative that shows how the class wars of rising inequality are a threat to the global economy and international peace--and what we can do about it.

We use micro data collected at the border and at retailers to characterize the effects brought by recent changes in US trade policy - particularly the tariffs placed on imports from China - on importers, consumers, and exporters. We start by documenting that the tariffs were almost fully passed through to total prices paid by importers, suggesting the tariffs' incidence has fallen largely on the United States. Since we estimate the response of prices to exchange rates to be far more muted, the recent depreciation of the Chinese renminbi is unlikely to alter this conclusion. Next, using product-level data from several large multi-national retailers, we demonstrate that the impact of the tariffs on retail prices is more mixed. Some affected product categories have seen sharp price increases, but the difference between affected and unaffected products is generally quite modest, suggesting that retail margins have fallen. These retailers' imports increased after the initial announcement of possible tariffs, but before their full implementation, so the intermediate passthrough of tariffs to their prices may not persist. Finally, in contrast to the case of foreign exporters facing US tariffs, we show that US exporters lowered their prices on goods subjected to foreign retaliatory tariffs compared to exports of non-targeted goods.
