In this episode of The Sound of Economics, host Rebecca Christie speaks with Bruegel’s Heather Grabbe and Stefanie Walter about Iceland’s referendum on restarting European Union accession talks, Switzerland’s upcoming votes on EU relations and what Europe has to offer for countries inside and outside the club. Why did Icelandic voters reject the proposal to reopen talks? Why does Switzerland have such a complicated relationship with its neighbouring countries, even as it remains part of the Schengen passport-free travel zone? Economic and security concerns are more intertwined than ever with Europe’s relationships with the United Kingdom, Ukraine and North Africa, especially given changes at NATO. Democracy is the cornerstone of Europe’s alliances and also comes with a host of complications – how can the European institutions position Brussels best?

In this episode of The Sound of Economics, host Rebecca Christie speaks about how to fight financial crime with Bruegel’s Nicolas Véron and James Freis, former chief compliance officer at Deutsche Börse and former head of FinCEN, the United States Financial Crimes Enforcement Network. The European Union is setting up its new Authority for Anti-Money Laundering and Countering the Financing of Terrorism (AMLA), which from 2028 will have a combination of supervisory and standard-setting duties. What does it mean to start a new EU agency? What effect will it have for prevention and enforcement in areas like fraud, tax evasion and other abuses? What is the EU’s history in this area, and what past weaknesses is the new agency trying to correct? Given such a big and important mandate, will AMLA have the resources to do its job?

How can Europe emulate US dynamism and economic growth while also resisting the conflicts of interest that arise when money and policy overlap? Will proposals currently pushed by the European Commission – like 'EU Inc' and the Capital Markets Union – shift the needle in this regard? What role does taxation play?

In this episode of the Sound of Economics, host Rebecca Christie sits down with Bruegel Director Jeromin Zettelmeyer, researcher Silvia Merler and Bank of France Deputy Governor Agnès Bénassy-Quéré to talk about common European debt and the idea of a 'safe asset'. What makes government bonds a part of public infrastructure as well as a tool for financing public goods? Why is how to borrow money for public goods treated as a separate question from how to spend it? Should the European Union sell more common debt or look at a layered system that works with national borrowers, such as the swap proposal put forward by Olivier Blanchard and Angel Ubide? Will United States Treasury bonds always be the world’s only major reference asset, or will the EU get a seat at that table? This episode discusses what a safe asset is, why it matters to Europe and what steps policymakers should take next.

In this episode of The Sound of Economics, Yuyun Zhan and Alicia García-Herrero are joined by Bertin Martens and Paul Triolo to take stock of the global artificial intelligence race, from energy and chips to models and applications. They discuss China's progress in catching up to the US, what the recent turmoil around Anthropic's most advanced models reveals about the politics of releasing frontier AI and why Europe, dependent on the US for both chips and models, is left exposed on all sides. They explore whether an "Airbus for AI", an initiative for pooling compute, capital and expertise across member states, could close the gap, and what it would take for Brussels' new cloud and AI industrial proposals to matter at scale.

In this episode of The Sound of Economics, host Rebecca Christie talks about the future of European Union-United Kingdom relations with Bruegel’s Heather Grabbe and Richard Corbett, a former UK Labour Party MEP and also a former advisor to a president of the European Council. Did Brexit turn out the way its supporters hoped, and what have been the economic costs? Will the UK look to rejoin the single market any time soon? The EU has a slate of prospective new members lined up for closer relations who could take priority, especially Ukraine, whose candidacy has been fast-tracked because of the ongoing war. How does Kyiv’s progress affect British prospects? Would the UK have to join the euro if it wanted to come back fully? Are other kinds of relationships possible? With global uncertainty higher than ever, the UK and the EU still have great incentive to work together.

In this episode of The Sound of Economics, host Rebecca Christie looks into the future with Bruegel’s emerging talents Maria Catarina Louro, Tillman Schenk and Théo Storella. Demographic change is coming for the world, as fewer new workers grow up to replace earlier generations of workers. China is at a crossroads of not only population decline but also industrial dominance, putting its economy in renewed competition with the United States and Europe. And artificial intelligence will change the workforce, the manufacturing base and the productivity outlook all over the world. How should current policymakers and thinkers shape the world that lasts beyond their lifetimes? How can the field of economics contribute?

In this episode of The Sound of Economics, host Rebecca Christie speaks with Bruegel’s Simone Tagliapietra and Flora Marchioro about the European Union’s pathbreaking carbon trading scheme. Two decades in, what have we learned about capping emissions and using tradeable allowances to rein in pollution from energy-intensive sectors? What are the stakes of this year’s review of ETS, which includes electricity and heat generation, industrial manufacturing, domestic aviation and the maritime sector? Why is the EU now creating a second round of ETS 2, covering buildings and road transport, and what are its prospects? Who gets the money from ETS revenues and how is it earmarked? And how is the EU working to prevent carbon leakage and manage its new carbon border adjustment mechanism? This discussion will get you up to speed and ready for what comes next.
