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 se...

Textbook economics says a tariff should strengthen a country's currency. Since the start of 2025, as US tariffs rose ... and the dollar fell.

In the first of four episodes of Voxtalks based on papers presented at the second Economic Policy: Papers on European and Global Issues conference, Alfonso Merendino (Bocconi University) and Tommaso Monacelli (Bocconi University, CEPR) tell Tim Phillips what they found when they looked for reasons. Their conclusion: for tariffs, it's not size, it is how permanent people expect it to be. They call this structural trade policy uncertainty. 

When that uncertainty is low, a...

Norwegian conscripts arrive at boot camp straight out of school. They are assigned at random to a shared room and they live in it for the next eight weeks. Whatever the culture of that room turns out to be, they are stuck with it.

We know that the military everywhere has a poor record on sexual harassment. Johanna Rickne (Stockholm University, CEPR) and her co-authors wanted to reduce its acceptance, and the number of incidents. 

Compulsory training, standing a in a room a showing a PowerPoint, has a poor record. It can even inspire a b...

In the oldest Japanese municipalities, close to half the residents are already over 65. As young people move to cities, the retailers close, then the clinics, then the bus that used to reach the next town. Rural Japan is not simply ageing: it is emptying.

Elisa Giannone (CREI, CEPR) and her co-authors have analysed Japan's 1,741 municipalities from 1980 onwards. The oldest quarter of them lost around 26% of their population by 2010; the youngest quarter grew by 22%, and the gap between them is still widening. 

Taxing city dwellers could reverse the trend. But that's a century-long policy, that would a...

Travel broadens the mind. So the Voxtalks visits a conference, we find the most interesting research from economists just starting out, and hand three of them a microphone. Ad that is today's episode, recorded at the CEPR Paris School of Economics Policy Forum 2026.

Listen to hear three findings that undercut conventional wisdom. Guido Lamarmora (University of Nottingham) argues that the usual policy prescription for developing economies that want to industrialise of raising agricultural productivity can deepen their reliance on farming rather than break it. Costanza Tomaselli (Imperial College London) studies what an energy price shock in Mexico...

A country wants a stable exchange rate, it wants money to move freely across its borders, and it wants to set its own interest rates. It's a well-known trilemma. Central bankers must pick any two, because you cannot have all three. 

History, it turns out, did not read that memo.

Eric Monnet has spent years reading the balance sheets that central bankers kept on each other. Since 1891 the Bank of France paid teams of multilingual economists to copy out the weekly and monthly accounts of every other c...

If you run a business that exports to the United States, how big is the tariff you have to pay? In 2025 that question was hard to answer. Between February and December, 53 separate announcements introduced, delayed, reinstated or changed US tariffs, with different countries and products pulled in or exempted each time.

Kalina Manova (UCL, CEPR) and her colleagues built a database of every one of those announcements, but they also measured  the confusion that those announcements created. She tells Tim Phillips about how tariff confusion has become a second tax on trade, as confusion puts off exporters: b...

Tariffs move trade around, but so does economic power. When one economy dominates, other countries fall into step with it. They trade with the dominant economy, and also with each other. 

Alberto Martin (Barcelona School of Economics, CEPR) is one of a team that has tracked the influence of hegemons, large dominant economies, on trade from the start of the 19th century. In  our latest VoxTalk he tells Tim Phillips about how they used treaties (not necessarily about trade) as a proxy for alignment, and bu...

In 2019 the IMF called the increasing adoption of industrial policy: "The return of the policy that shall not be named". No one is scared to name it in 2026. Governments in rich and poor economies alike are intervening to change what their countries produce, and the pace has picked up sharply.

Zsóka Kóczán (EBRD) was one of the leads on the Transition Report 2024-25, which draws on a database of more than 31,000 industrial policies in 150 economies. She talks to Tim Phillips about who is using these pol...

In 1941 the United States banned oil exports to Japan, to punish aggression without fighting a war. Historians now argue the embargo did the opposite, and hastened Japan's entry into the war.

Isabelle Méjean (Sciences Po, CEPR) calls this "The safety paradox". Trade between rivals makes war more expensive. Cut that trade to protect your interests, and you make conflict cheaper, for your rival as well as for you. In a new VoxTalk she talks to Tim Phillips about economic coercion, decoupling, and why E...

French teenagers carry a smartphone with access to almost anything, but few of them have been using it to read the news.

Julia Cagé (Sciences Po, CEPR) ran an experiment to test the one barrier everyone assumes matters most: the price of a newspaper. She and her co-authors gave free digital subscriptions to Le Monde and media education to thousands of French high school students for a year, and then tracked what the students actually read. It's a bit like persuading kids to eat vegetables when there are fries on the table, she tells Tim Phillips. Can a...

Sixty-three percent of large companies worldwide had made a net zero commitment by 2023, up from close to none in 2018. But if the target date is 2050, that's several corporate lifetimes away, and the planet needs emission reductions today. What actually changes in the boardroom when a pledge is signed?

Simon Dietz (LSE, CEPR) has tracked climate management practices and emissions at nearly 2,000 companies to find out. He tells Tim Phillips that the picture is not the one that either side of the debate might expect. A net zero pledge doesn't usually signify an immediate cut in emissions, but...

Europe is under attack from the US, and under a different kind of attack from China.

That is Olivier Blanchard's diagnosis. Blanchard (MIT, Paris School of Economics, Peterson Institute) is one of four economists leading Europe 2050, a new CEPR initiative asking where Europe wants to be in 25 years, and how it gets there. Blanchard's overriding principle: a vision without plumbing goes nowhere, and plumbing without vision is just reacting to the next tweet.

Who can combine the vision and the plumbing, and produce ideas t...

China cannot sell as much as it used to in the United States. That trade has to go somewhere, and somewhere might be Europe.

In this week's VoxTalk, Tim Phillips asks Pol Antràs (Harvard) and Beata Javorcik (EBRD, Oxford) what this means for European producers and consumers.

Antràs and Andrea Presbitero have mapped which countries and sectors face the sharpest competition from redirected Chinese exports, and which stand to gain. Does cheap Chinese tech ease Europe's energy cost crisis, or squeeze European manufacturers of wind turbines and electric cars?

If Europe de...

Twice before, the world's savings and debts have piled up in the wrong places, and twice the imbalance broke something. The first time it took the Plaza Accord to fix it. The second time it took a global financial crisis.

Now we are in a third wave. Gita Gopinath (Harvard, former IMF Chief Economist and First Deputy Managing Director) and Philip Lane (European Central Bank, CEPR) join Tim Phillips to ask what is different this time.

Household and bank balance sheets are...

Lose your job at 25 and someone will help you find another. Lose it at 55 and the talk quietly turns to how you might wind down towards retirement.

Policymakers tend to assume job search training works for the young and not the old, so they rarely spend money trying. Bas van der Klaauw (Tinbergen Institute) thinks they got that wrong.

In this week's VoxTalks Economics, he tells Tim Phillips about a Dutch experiment that put older unemployed workers through an intensive programme built on one idea: teach people over 50 to find work the way younger workers...

Who kept the courts sitting and the streetlights lit when the state had almost no money to pay anyone?

Two hundred years ago, British local government ran on unpaid labour. In a parliamentary survey of the boroughs from 1835, two in three of the people doing local government work were not paid at all.

James Robinson (University of Chicago, CEPR) explains how this succeeded in this week's episode of VoxTalks Economics. Robinson and his co-authors call this the "embedded state". Members of the elite willingly took the unpaid jobs because the postings carried prestige and led...

Defence spending is rising whether voters like it or not. The UK has committed to 2.5% of national income and aims for nearer 3.5% over the next decade, £30bn a year for each percentage point. What does the country get back? Can defence spending be pro-growth?

In this week's VoxTalk, John Van Reenen (LSE) argues that getting a return on investment based on innovation need not be left to luck. For example nuclear power, GPS and the internet all began as military projects. The spillovers can be planned for; the trick is to make defence spending innovation-rich, and make p...

In January 1860 the New York Times gave its blessing to a new machine: the sewing machine. These "iron needle-women", it wrote, were the only invention that could be claimed “chiefly for women's benefit”. Sewing was women's work in the nineteenth century, rich or poor, and a machine could now do it in a fraction of the time. So did it set women free?

Philipp Ager and Davide Coluccia have traced the adoption of the sewing machine in Massachusetts between 1850 and 1900, using census records and digitised business directories to work out who was exposed to it, in the fact...

Every day, billions of transactions settle between strangers who have no idea which bank the other uses. That lack of friction is not automatic. Nine-tenths of the money in daily circulation has been created by commercial banks, but it stays trustworthy only because central banks stand behind it, and keep the system in balance.

In this week’s episode Tim Phillips talks to Stephen Cecchetti (Brandeis University, CEPR) about what happens when new forms of digital money test that architecture. Cecchetti is one of the authors of the eighth Barcelona Report in The Future of Banking series, pa...

Someone once held a patent on the swing. A piece of wood. Two ropes. The US Patent Office granted it. How often does that actually happen, and what does it cost when the system gets it wrong? Or, how often is a valid patent claim rejected?

Until now, no one knew. Tim Phillips talks to Mark Schankerman of LSE and CEPR, who with co-authors William Matcham spent eight years building the tools to find out. Using natural language processing across a dataset of around one million patent applications, twenty million claims, and fifty-five million examiner decisions, they...

The fiat money system has survived the Great Inflation, the global financial crisis, and a pandemic. But can it survive digital currencies?

Bitcoin and the blockchain solved a genuine problem in computer science: how to stop people spending the same money twice. Forty years of successful inflation control means central bank money is stable; that is the stability in stablecoins, attempting to solve the volatility problem. What's next? What if the unit of account itself were indexed to consumer prices? Digitalisation might finally make that approach viable at scale. Price stability, by design.

Will we...

Europe's NATO members have pledged 3.5% of GDP to rearmament. The political argument is already about which social programmes will be sacrificed to pay for this, when the government chooses guns instead of butter. What does history tell us about what politicians will do?

Christoph Trebesch and Johannes Marzian spent four years assembling the Global Budget Database: 150 years of primary government budget documents from 20 countries, with 116 identified military spending booms in peace and war. They find that governments almost never cut social spending when they rearm; they expand both military and welfare budgets simultaneously. The bill arrives later...

More than one in eight people living in the EU today was born in another country. In fourteen of the bloc's largest economies, it is closer to one in six. For ten years, the same team of researchers has asked what happens to those people next: do they find work, close the gap with their native-born neighbours, and build a settled life? The tenth Migration Observatory report is about to be published, and the decade-long picture it paints is not what the political debate might lead you to expect.

Tommaso Frattini of the University of Milan, one...

Content note: this episode discusses assisted dying, end-of-life choices, and suicide. Some listeners may find the content distressing.

In April 2024, Daniel Kahneman — one of the most influential psychologists of the twentieth century — emailed his close friends to say goodbye. He was 90 years old, his kidneys were failing, his mental lapses were increasing, and he had decided it was time to go. He flew to Switzerland to end his life at an assisted dying clinic there, because New York, where he lived, did not permit it. Thirteen American states currently allow medical assistance in dying; most require a term...

The standard story of American innovation features Silicon Valley, venture capital, and the heroic startup founder.When you trace the history of the internet, GPS, mass-produced penicillin, or the COVID vaccine, the starting point is not a term sheet but a government grant. How much does this matter,  and can we measure it?

Tim Phillips speaks to Paolo Surico of London Business School and CEPR who, working with Andrea Gazzani, Joseba Martinez, and Filippo Natoli, has built the first systematic empirical account of how government-funded innovation has shaped US productivity since the Second World War. The headline r...

In 2003, Premier Wen Jiabao warned that China's growth model was unbalanced between supply and demand, over-reliant on investment and exports. More than 20 years later, the imbalance is smaller — but China is vastly larger. What its economy produces and exports now moves global markets. The argument about China's external surplus is no longer just a spat between Beijing and Washington.

Yiping Huang, Dean of the National School of Development at Peking University, has written a chapter in the fourth Paris Report, published jointly by CEPR and Bruegel, examining China's structural imbalances from the inside. His argument: the same po...

A radical macroeconomic experiment is under way at exactly the moment the US external position is showing signs of real stress.

Gilles Moëc, Chief Economist at AXA, has written a chapter in the fourth Paris Report, published jointly by CEPR and Bruegel, on stablecoins: what they are, why the US government is so keen to promote them, and what risks they carry. His argument is that stablecoins are a fast-growing digital asset backed almost entirely by short-dated US government debt. When investors buy a dollar stablecoin, they are effectively buying into a US T-bill at zero i...

Three times since the 1970s, global imbalances have grown large. In the 1980s, the US trade deficit ballooned under Volcker's tight money and Reagan's tax cuts and military spending. In the 2000s, a global savings glut and then a US housing credit boom pushed the deficit to 6% of GDP. Today, the imbalances are back. The US current account deficit stood at 3.9% of GDP in 2025. 

The policy medicine this time: tariffs.

Maurice Obstfeld of the Peterson Institute for International Economics and CEPR has written a chapter in the fourth Paris Report, published jointly by CEPR and B...

On 2 April 2025, the United States imposed tariffs on almost every country on earth. The next day, China responded with export controls on the entire world. In the space of one week, world trade had been weaponised as it has never been in peacetime.

Richard Baldwin of IMD Business School, the founder of VoxEU and a former president of the Centre for Economic Policy Research, wrote World War Trade to make sense of the events of the last 12 months. The dramatic April salvos have settled into a trade Cold War; US tariffs and Chinese export controls are lodged...

"When you look at the world now, does it look more uncertain or less uncertain?" In December 2025, the Bank of England's Financial Policy Committee (FPC) answered that question by cutting the equity capital requirement for UK banks. David Aikman (NIESR) and John Vickers (University of Oxford), two former senior Bank insiders who helped to design the regulatory framework post-GFC, think the committee got it wrong.

The FPC lowered the benchmark capital requirement from 14% to 13% of risk-weighted assets, a move that could free up roughly £30 billion of capital across the UK banking system. Aikman and Vickers see no c...

Two explanations circulated immediately after the March to Save America on January 6, 2021 turned into a riot: a mob manipulated by a demagogue, or ordinary citizens defending democracy against a stolen election. Konstantin Sonin, David Van Dijcke, and Austin Wright have used anonymised location data from forty million mobile devices to investigate why the protests escalated so dramatically.

No surprise: partisanship was the strongest predictor of attendance, proximity to Proud Boys chapters and use of the far-right social network Parler also increased participation. But political isolation amplified the movement: the communities most over-represented among those who traveled to...

Every Bitcoin transaction needs to be verified on the blockchain. There is no central authority that does this, but Bitcoin's blockchain has run uninterrupted since 2009 and now carries a market capitalisation of $1.3 trillion, roughly 4% of US GDP. Its original promise was more radical: that we do not need a trusted intermediary to spend money, write contracts, or create finance. In the fifth LTI report, published today, Yackolley Amoussou-Guenou, Bruno Biais, and Sara Tucci-Piergiovanni ask how much of that promise has held. 

Bruno talks to Tim Phillips about blockchain’s potential, its flaws, and its future.

Could AI transform our economies to produce explosive growth? Most economists are sceptical at best. Anton Korinek of the University of Virginia, leader of the CEPR research policy network on AI, thinks the threshold is closer than those models suggest.

In his latest work, Korinek, Tom Davidson, Basil Halperin, and Thomas Houlden, have built a growth model that captures what happens when AI starts automating AI research itself. Automation does two things simultaneously: it accelerates research, and it offsets the diminishing returns that have historically stopped self-improving processes from compounding. Three reinforcing feedback loops: software quality, hardware...

Financial repression forces banks and citizens to hold government debt on terms the market would never accept. Economists have called it distortionary for fifty years. It never went away.

Oleg Itskhoki and Dmitry Mukhin study what happens when a government runs out of options. Their paper traces how Russia deployed financial repression in 2022 to survive the largest sanctions package in postwar history. The ruble was in freefall; banning cash withdrawals and forcing exporters to hand over foreign currency revenues stopped the crisis. The measures worked because Russia kept earning export income, and the sanctions...

Ukraine has lost close to a quarter of its civilian workforce since the invasion. Three and a half million workers left government-controlled areas: mobilised into the armed forces, displaced inside the country, gone abroad as refugees, or killed. 

Giacomo Anastasia, Tito Boeri, and Oleksandr Zholud draw on an unprecedented wartime dataset to document how Ukraine's labour market adapted under that pressure. What they find is not what you might expect. Aggregate matching efficiency fell by only about 15%; less than the decline recorded in the United States during the 2008 financial crisis. Firms hired women into roles previously closed t...

Ukraine's cities were failing long before the Russian invasion began. Kyiv and Lviv ranked among the 40 most congested cities in the world, yet neither makes the top 100 by population. Ninety per cent of Ukraine's housing stock was built before 1990. Its urban infrastructure was designed for a Soviet economy and never properly adapted for the one that followed. So when reconstruction begins, the question is not simply how to repair what was there: it is whether repairing what was there is the right goal.

Edward Glaeser of Harvard, Martina Kirchberger of Trinity College Dublin, and Andrii Parkhomenko of...

Ukraine will emerge from this war with enormous debt. The conventional wisdom treats that as an obstacle: investors weigh it before committing capital, and the burden slows the recovery before it starts. Yuriy Gorodnichenko and Maurice Obstfeld of UC Berkeley argue the opposite. A thorough restructuring of Ukraine's war debts – including, for sufficiently large obligations, outright forgiveness – is not just politically defensible but economically essential for attracting private investment. 

The bill for rebuilding and growing Ukraine, Gorodnichenko estimates, is $40 billion a year: $20 billion to replace destroyed capital, $10 billion to stop Ukraine falling behind its Eastern European peers, and $...

Recorded live at the CEPR Annual Symposium. We seem to be talking about the behaviour of alpha males on social media a lot recently. But what happens when we put them in charge of a country? The work of Mario Carillo of Universitat Autònoma de Barcelona attempts to answer that question. He talks to Tim Phillips about when and why voters choose alpha males, and how they respond to being given power.

What type of manager would you be? An experiment in Ethiopia set out to measure the management traits of young professionals by setting them challenges in a video studio, and along the way also uncovered valuable (and surprising) information about the type of manager that employees and employers preferred.

Simon Quinn of Imperial College London and CEPR and Tom Schwantje of Bocconi University were two of the researchers. They tell Tim Phillips about why it is important to develop better managers, and how we might do that for young professionals.
