In this episode of The Sound of Economics, host Rebecca Christie talks about the rise of billionaires in the global economy and United States politics with guests David de Jong, author of the nonfiction book Nazi Billionaires, and Karel Lannoo, chief executive of the Brussels-based think tank CEPS. How are today’s billionaires shaping the US political climate, and how have things changed from the first Trump administration? What are the geopolitical consequences? 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? This episode tackles some of the hard and complicated questions about money, politics and prosperity in today’s world.

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.

In this episode of The Sound of Economics, host Rebecca Christie discusses the European Commission’s spring economic forecast with Bruegel’s Andreas Billmeier and Mahmood Pradhan. Growth is slowing down while inflation surges in response to higher energy prices. Is the job market on the brink of a bigger slump? Will energy markets adjust again or will this cycle last longer? How might the European Central Bank react? Looking outside the European Union, how is the UK economy faring? Will the costs of Brexit force a reassessment of UK-EU relations in London? As long as global conditions remain so uncertain, European economies are unlikely to bounce back – so how can policymakers find the growth they need? With bigger economies like Germany and Italy in the doldrums while Poland, Denmark and Sweden show more resilience, how should the EU respond and what could be coming next?

In this episode of The Sound of Economics, Yuyun Zhan and Alicia García-Herrero sit down with Jonathan Fulton to interrogate some persistent assumptions about China's role in the Middle East. From the China–Iran partnership to the Saudi–Iran rapprochement, they explore whether the conventional wisdom misreads a deeply complex region – overstating Chinese ambition, understating local agency and flattening a relationship that is transactional, rather than strategic.
