There is a saying in Spanish: get burned by hot milk, and the sight of a cow makes you cry. New research implies that, decades after a populist government leaves office, the central bank it once tried to control is still flinching.Martín Uribe (Columbia) and Nicolás Magud (IMF) have investigated the long-run effect of populist governments that leaned on their central banks to print money and feed inflation. They find that these central banks raise interest rates more aggressively than others when inflation drifts above target, even decades later.This is the second of four episodes drawn from papers commissioned for the second Economic Policy: Papers on European and Global Issues conference, organised by CEPR, CESifo and Sciences Po.The research behind this episode:Jácome, Luis, Nicolás E.

Mundell Professor of Economics at Columbia University and a Research Associate of the National Bureau of Economic Research.

He is editor-in-chief of the Journal of International Economics.<a href="https://www.imf.org/en/blogs/authors/nicol%C3%A1s%20magud">Nicolás E. Magud</a> is a Senior Economist in the International Monetary Fund's Western Hemisphere Department. His research spans open-economy macroeconomics, with a focus on fiscal policy, exchange rates, capital flows, and capital controls, much of it drawn from Latin America's long experience of inflation and central bank reform.Research cited in this episodeThe populist leaders database.

The authors classify a leader as populist if their rhetoric splits society into "the people" against "the elites," then divide populists into left-wing, whose target is economic elites, and right-wing, whose target is foreigners and minorities. Deficit monetisation and "unpleasant monetarist arithmetic."

The paper that established the mechanism this episode turns on: when a government's deficit is financed by its own central bank printing money rather than by selling bonds to the public, the result is inflation.

The statistical method behind the paper's headline charts.

A dataset scoring central bank laws on their independence, including limits on lending to government. The paper uses it to show that countries with a populist past, especially a left-wing one, now have stricter legal limits on central bank lending than countries with no such history.Argentina, Chile, and Mexico. The paper's three historical case studies. In Argentina, governments from PerÃ³n onward repeatedly rewrote central bank law to permit financing of the treasury, contributing to repeated bouts of high inflation and, eventually, hyperinflation in the 1980s. In Chile, the Allende government printed money to fund an expansion of the state, and inflation reached roughly 600% in 1973 before the government was overthrown. In Mexico, President EcheverrÃ­a's public investment drive in the 1970s was financed in part by the central bank, feeding an inflation and currency crisis that culminated in the country's 1982 default. Uribe and Magud point to these episodes as the historical template their statistical results describe.Related reading on VoxEU<a href="https://cepr.org/voxeu/columns/central-bank-independence-update">Central bank independence: An update</a>, a VoxEU column in which Sylvester Eijffinger and Jakob de Haan argue that legal independence alone does not shield a central bank from political pressure to loosen policy.<a href="https://cepr.org/voxeu/columns/recent-trends-central-bank-independence">Recent trends in central bank independence</a>, in which Davide Romelli, whose index this paper uses to track legal independence, documents a fresh wave of reforms strengthening central banks worldwide since 2016.</div>
