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.

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

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.

"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.

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.

This working paper presents a comprehensive overview of the theoretical structure of the Global Integrated Monetary and Fiscal Model (GIMF), a multi-region dynamic general equilibrium model that is used by the IMF for a variety of tasks including policy analysis, risk analysis, and surveillance.
