The Sound of Economics

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 speaks about the future of work with Bruegel’s Alexandre Mendonça and MIT professor Paul Osterman, author of a new book called Disposable Workers: the Transformation of Employment. In the United States and the European Union, companies are shifting away from long-term permanent jobs to a system with less certainty. Which industries have been most affected and how does that look for their workers? Who benefits from part-time work? Which workers are most disadvantaged? How can public policy adjust around these new dynamics? Artificial intelligence changes what skills workers need and immigration trends shape which workers are available. What conditions will help the economy grow and thrive?

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.
