82 - Doug Irwin on the History of US Trade Policy

Episode Summary

Executive Summary: Doug Irwin discusses his book Clashing Over Commerce, arguing that U.S. trade policy is best understood as a shifting political struggle across three long regimes: revenue, restriction, and reciprocity. The conversation ties tariffs, trade wars, and policy entrepreneurship to broader economic history, including the Civil War, Smoot-Hawley, the Great Depression, gold standard dynamics, and modern Trump-era protectionism.

Main Topics: Three regimes of U.S. trade policy (Priority: 5/5): Irwin frames U.S. trade history as a sequence of long-lived tariff regimes: revenue (1763-1865), restriction (1865-1932), and reciprocity (1932-present), each shaped by different political and economic motives. Trade policy as political conflict and status quo bias (Priority: 5/5): The discussion emphasizes that trade policy is driven by persistent regional and political conflict, with strong resistance to changing an established tariff regime once interests form around it. Revenue tariffs and the founding of the U.S. (Priority: 4/5): Early U.S. tariffs were mainly about raising federal revenue, helping justify the Constitution and funding government debt; Hamilton favored promotion of manufacturing more than protection. Civil War and the rise of protectionism (Priority: 5/5): The Civil War created a revenue shock that pushed tariffs higher and, after the war, special interests and Republican dominance helped lock in a protectionist regime for decades. Smoot-Hawley and the Great Depression (Priority: 5/5): Irwin argues Smoot-Hawley was politically motivated, not economically necessary, and that it worsened the Depression by triggering retaliation and damaging exports. Reciprocity, trade liberalization, and WWII order (Priority: 4/5): The Depression helped discredit protectionism and led to reciprocal trade agreements under Cordell Hull, then post-WWII multilateral liberalization through GATT as part of broader U.S. international engagement. Gold standard and the Great Depression (Priority: 4/5): Irwin connects monetary history to trade history, arguing that French gold accumulation and U.S. sterilization helped deepen deflation and the downturn, while the 1937-38 recession was also tied to sterilizing gold inflows.

Key Arguments: U.S. trade policy is not a straight ideological story; it is a history of changing political coalitions, regional interests, and institutional constraints. High tariffs are hard to reverse because once a regime is in place, beneficiaries mobilize while the diffuse gains from lower tariffs are politically weaker. Hamilton was not primarily a protectionist; he wanted manufacturing promotion but prioritized revenue and a stable tax base. The Civil War was the major break that shifted U.S. trade policy from revenue raising toward lasting restriction/protection. The South’s tariff grievance was real in the 1820s but had largely dissipated by 1860; slavery, not tariffs, was the core cause of the Civil War. Smoot-Hawley was not driven by a genuine market need; it was a political response to farm pressure and then expanded by manufacturers. The Depression-era turn to reciprocity was helped by the visible failure of protection and by retaliation against U.S. exports. Postwar trade liberalization was linked to foreign policy goals: avoiding post-WWI isolationism and building an open world economy. Economic nationalist claims that tariffs caused 19th-century U.S. growth confuse correlation with causation; growth was driven more by immigration, capital formation, and services. Monetary factors mattered in the Great Depression: French gold accumulation and U.S. gold sterilization reduced global monetary growth and intensified deflation.

Data Points: U.S. trade policy coverage in book: 1763 to Donald Trump - Irwin describes the scope of Clashing Over Commerce Tariff regimes: 3 - Revenue, restriction, and reciprocity are the book’s main organizing periods Revenue period: 1763-1865 - Tariffs mainly used to raise government revenue Restriction period: 1865-1932 - Tariffs mainly used to protect domestic industry Reciprocity period: 1932-present - Tariffs used as bargaining leverage for trade agreements Jefferson embargo GDP cost: about 5% of U.S. GDP in one year - Irwin estimates the welfare cost of the embargo Great Recession GDP decline: about 3% - Used as comparison to the embargo’s severity Average tariff by 1860: less than 20% - Irwin uses this to argue the tariff issue had largely been defused before the Civil War U.S. unemployment in 1929: about 3% - Used to show Smoot-Hawley was not a response to depression-level conditions U.S. fiscal position after Civil War: $2 for every $1 spent - Describes the surplus that made tariff cuts politically contentious French gold share in 1926: 7% of world gold supply - Beginning of French gold accumulation story French gold share in 1932: 27% of world gold supply - Shows the scale of gold absorption before the Depression deepened Smoot-Hawley passage: June 1930 - Tariff passed after the recession had already begun World War II trade architecture: GATT - Postwar multilateral trade liberalization framework discussed by Irwin China current account surplus: 10% of GDP - Used by Beckworth to compare modern external imbalances with gold-standard-era adjustment problems

Pivotal Quotes: "There’s no one way of answering this question and it’s going to be one of a political struggle." — Doug Irwin: On Madison’s view of trade policy as a continuing domestic political conflict "It’s an unnatural act to reduce those because you know who you’re going to hurt." — Doug Irwin: On why tariffs are politically sticky once vested interests form "We’re not going to have higher tariffs. We’re just going to stop trade for a year and get rid of the trade deficit that way." — Doug Irwin: On the Jefferson embargo as an extreme trade restriction

Implications: The episode suggests trade policy shifts only when shocks, visible failures, and political entrepreneurs align. For today, that means protectionism can persist despite bad outcomes, while liberalization needs clear evidence and strong leadership.
