Stablecoins are digital tokens, pegged to a fiat currency. What could possibly go wrong?For one type of stablecoin the answer is: plenty, according to Richard Portes. The founder and honorary president of CEPR is also co-chair of the European Systemic Risk Board Crypto Asset Task Force. In this role he has been investigating the risks of multi-issuer stablecoins in Europe. He tells Tim Phillips that, if one of these stablecoins hit trouble, US holders could use European regulation to recover their investment from the coin’s European reserves. And that, he argues, would be a threat to Europe’s financial stability.

In another of our special episodes recorded at the CEPR annual Symposium, we ask: is it time for Europe to rearm?The message from the US could not be clearer: it is time for European countries to take care of their own security. If Europe decides to rearm, it has the industrial base – but Moritz Schularick of the Kiel Institute and CEPR warns that it isn’t converting that capacity into credible deterrence. Tim Phillips asks him what European rearmament could mean in practice: not just scaling up production but buying smarter and investing in next-generation technologies that can spill over into the wider economy. And is there enough political will to create a European defence architecture that can stand on its own?

In another of our episodes recorded at the CEPR Paris Symposium, we ask: When Gen AI can do an undergraduate’s problem set in seconds, how should teaching, and the syllabus, respond? Who better to answer this than Wendy Carlin of UCL and CEPR? Wendy – who has recently become Dame Wendy – was at the symposium to talk about her project to change economics teaching through the CORE Project, which more than 500 institutions use to teach introductory economics in a way that flips the standard textbook treatment on it head.Recently Wendy and CORE have been working to harness the power of AI to help students apply their knowledge in unfamiliar settings, to reason and discriminate, to make AI into what she calls “A cognitive sparring partner”. She tells Tim Phillips what that means for the Economics Major, and why that might create economics graduates with the skills that employers value. Try CORE, it’s free: https://core-econ.org

Another special episode recorded at the CEPR annual symposium in Paris. The Trump administration says it wants America to lead in AI, but what does that mean in practice for trade and productivity? Will AI make growth great again, or just inflate a short-term capital spending boom?Gary Gensler of MIT and CEPR (also a former chair of the Securities and Exchange Commission) unpacks the administration’s AI action plan, helps us work out what's happening to export controls, and untangles the deal-making geopolitics of AI hardware. 

At the CEPR annual Symposium in Paris we sat down with Adam Posen, president of the Peterson Institute for International Economics, a distinguished fellow of CEPR, and a global authority on geopolitics and trade to discuss the profound changes in the multilateral order in 2025, how countries will adjust to this new normal – and whether the changes we have seen will ever be unwound.

Who would be a policymaker right now? The list of economic problems that we need to solve ranges from “very difficult” to “existential”. An ambitious new book collects the ideas of many influential economists on how to approach these challenges. But can it avoid the mistakes of previous attempts to find an economic policy consensus?Andrés Velasco and Tim Besley are two of the editors of The London Consensus. Tim Phillips joined them at The London School of Economics to ask why the book was created, how policymakers can use it, and whether we should be wary of economists bearing paradigms.Here's a link to the the book (you can download it too).

Economic sanctions are the big geoeconomic bazooka. But what does history tell us about how well they work, and their relevance today. And does the theory match the data? Moritz Schularick of the Kiel Institute for the World Economy and CEPR talks to Tim Phillips about the evidence of the history of sanctions on what they can achieve, whether we expect too much too soon from small sanctions – and whether politicians are prepared to impose the sanctions that bite.

Biodiversity is essential for the wide range of economic activities that our planet needs. Yet, the economic consequences of its global decline are hard to estimate, because most population studies focus on individual species in isolation. Frederik Noack of the University of British Columbia argues that this misses a central insight about biodiversity: a healthy environment depends not just on individual species, but also on the way they work together to keep our natural environment in balance. One especially important aspect of this is the way that birds help keep crops safe from pests and reduce the need for pesticides. He tells Tim Phillips about the long-term decline of bird populations in the US and the knock-on effect on agriculture, and pollution. 

In 2021, at COP26, the International Accounting Standards Board announced it would create a standard for this reporting. It wants to integrate sustainability reporting with traditional IFRS accounting. Should firms be compelled by regulators to disclose their impact on the climate in their corporate reporting? Investors value convergence in sustainability reporting standards, but they are facing stiff opposition both in the US and Europe – even while developing economies embrace the new regime. Lucrezia Reichlin of the London Business School and CEPR talked to Tim Phillips on the progress to sustainability standards, the scope of reporting, who wants it, and who’s objecting to it. 

In Europe and beyond, populist politicians continue to gain ground. What message are voters sending? Are politicians from other parties listening, and explaining their policies in a way that will successfully reach supporters of populist parties? There are one set of policies for which this may be a huge problem soon. What does this mean for that those tricky choices that politicians will have to make when dealing with the consequences of climate change, and sustainability? Sergei Guriev of London Business School and Catherine de Vries of Bocconi University have both examined what is driving support for populism, and the implications of populism in politics for the social contract. They tell Tim Phillips why the planet may have a populism problem.

Our economy is embedded in nature, but nature is in danger. External funding is needed, especially in the Global South, to support the conservation of our natural ecosystems. Markets can play a role, but the way in which voluntary carbon markets do this has low public trust which, from recent news, may be deserved. Estelle Cantillon of Université libre de Bruxelles and CEPR tells Tim Phillips about her proposal for a new market mechanism to channel funds to projects that will conserve or restore our natural environment by paying dividends to those who invest. But how will it avoid greenwashing, and who will buy the shares?

“What is needed is non-marginal, transformative change to shift the economy, technology, and society”. That’s the typically forthright recommendation from Rick van der Ploeg of the University of Oxford and University of Amsterdam for how to ensure that climate policy is effective at changing our habits and behaviour. He argues that the gradual changes in habits that current policies target don’t go far enough, and that we run the risk of backsliding. But what does this mean in practice? Rick spoke to Tim Phillips about what policies to push, when to push them – and how big the push needs to be.

We are familiar with climate policy to reduce emissions. We know about the policies to adapt to climate change. But can we successfully reduce the amount of CO2 in the atmosphere, and how do we create policies and incentives to invest in, and take advantage of, those technologies? Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research and chair of the European Scientific Advisory Board on Climate Change, talks to Tim Phillips about an aspect of climate policy that is becoming increasingly important. 

"The Economics of Biodiversity” was published by the UK Treasury in 2021. It sets out how economic systems value biodiversity and natural capital, and which policies would preserve and restore nature. The project leader was Professor Sir Partha Dasgupta of the University of Cambridge. In the latest of our special episodes recorded at the first Hoffmann Centre / CEPR / ReCIPE Conference continue, he tells Tim Phillips what he learned from hanging out with ecologists, why we need indicators of economic performance that value nature, and why we should worry about the decline of natural capital.  The Economics of Biodiversity: The Dasgupta Review https://www.gov.uk/government/publications/final-report-the-economics-of-biodiversity-the-dasgupta-review

Can COP 30 get the green transition back on track? It’s not a great time for international cooperation right now and, with hindsight, was the period from 2017 to 2022 a “golden moment” the climate transition, and was it an opportunity missed? That’s the argument presented by Livio Stracca, Deputy Director General Financial Stability at the European Central Bank, also the chair of NGFS work on climate scenarios. He talks to Tim Phillips about what we can learn from this golden moment, and what can be done this time around to avoid the dangers of what Livio calls “climate agenda fatigue” among both the public and governments. 

In the first of our special episodes from the first Hoffmann Centre / CEPR / ReCIPE Conference, we’re discussing what chances there are of significant multilateral agreements being signed at COP 30 and, given that the chances are low, what plan B might be. Beatrice Weder di Mauro of CEPR, Hoffmann Centre and the Geneva Graduate Institute tells Tim Phillips that, if everyone can’t agree, then coalitions of the willing – climate or finance clubs that offer incentives for the countries that want to join – can agree their own sustainability policies. But what are those incentives? And who will lead?

A decade ago, the UK voted in a referendum to leave the European Union. It was the culmination of years of partisan arguments over membership. During that time, most newspapers in the UK took strong “leave” or “remain” positions in the stories they wrote. But were they less obviously partisan in their choice of pictures too? Wanyu Chung of University of Birmingham and CEPR was one of a team of researchers that used artificial intelligence to estimate the emotional impact of news images of politicians before and after the Brexit vote.

The International Macroeconomic History Online Seminar Series, hosted by CEPR, is turning 100 this month — not years, but episodes. What began as a lockdown experiment has become a global fixture for anyone who believes economics never forgets. In a special edition of VoxTalks Economics, Tim Phillips talks with organisers Nathan Sussman and Rui Esteves of the Geneva Graduate Institute about the moments that shaped the series and what a hundred lessons from history can teach us today. Why does history matter so much to economists? And how can the series help us understand current events?  Nathan’s selection The great demographic reversal https://cepr.org/multimedia/imhos-13-great-demographic-reversal-ageing-societies-waning-inequality-and-inflation Monetary and fiscal history of the US https://cepr.org/multimedia/imhos-81-monetary-and-fiscal-history-united-states-1961-2021 The journey of humanity https://cepr.org/multimedia/imhos-37-journey-humanity Rui’s selection The Smoot-Hawley trade war https://cepr.org/multimedia/imhos-26-smoot-hawley-trade-war Financial sanctions https://cepr.org/multimedia/imhos-59-financial-sanctions-arsenal-democracy-or-feeble-weapon Industrial policy https://cepr.org/multimedia/imhos-93-panel-industrial-policy-history

In the second of our episodes based on the topics discussed at the conference “Addressing the Risks and Responses to Climate Overshoot”, organised by the AXA Research Fund, CEPR, and Paris School of Economics, Tim Phillips talks to Matthias Kalkuhl of the University of Potsdam about how to remove carbon from the atmosphere. The innovative technologies that might be able to do this in the future need investment now – so one idea is for firms to buy the right to emit carbon now, as long as they commit to remove carbon when mature technology exists. But to administer this, Europe would need a dedicated Carbon Central Bank. Who would be in charge of it, how would it work, and is any politician brave enough to set it up?

In the first of two podcasts recorded at the conference “Addressing the Risks and Responses to Climate Overshoot”, organised by the AXA Research Fund, CEPR, and Paris School of Economics, Tim Phillips talks to Franck Courchamp of the University of Paris-Saclay about an aspect of climate change that is rarely talked about, increasingly important, and very costly. When plants or animals move, or are moved, to a place they don't belong, there is a risk of damage to natural habitats and an economic cost too. So how do we estimate the size of this risk, and what can we do about it?
