Luc Laeven, an economist at the European Central Bank and CEPR, discusses China’s remarkable rise in academic research, revealing how it has evolved from a knowledge consumer to a global leader in just two decades. He delves into the implications of China's strategic reforms initiated in 2006, contrasting their centralized research model with Western practices. The conversation highlights the surging quality and quantity of Chinese research, the challenges of measuring impact, and examines how Europe can revamp its funding strategies to compete in this new landscape.

Tim Besley, a Professor of Economics at the London School of Economics, dives deep into the relationship between economic growth and trust in government. He explores how long-term growth consistently builds trust across generations. The discussion highlights the impact of recent economic experiences on perceptions of trust, revealing cognitive biases at play. Besley contrasts various countries, examining how factors like transparency influence trust levels, especially among different age groups, shedding light on what truly inspires confidence in governance.

Yves Zenou, an economist at Monash University and a CEPR fellow, shares insights from his research on how friendship influences political opinions. He discusses a decade-old experiment at Sciences Po, revealing that brief social interactions among students can bridge political divides. The conversation touches on the impact of social media on political polarization and the significance of events like Integration Week in fostering connections. Zenou emphasizes the necessity of dialogue in reducing political extremism and promoting understanding across differing viewpoints.

With the major geopolitical powers squaring up to each other, tariffs on trade and political turmoil, is it time for economics to focus more on the consequences for the world economy of great power rivalry? A new paper defines the emerging field of geoeconomics, reviews the existing research, and sets out an agenda to fill the gaps in what we know. Christoph Trebesch of the Kiel Institute for the World Economy & Cathrin Mohr of Bonn University talk to Tim Phillips about how economists can collaborate with other disciplines to find fresh insights in this under-researched discipline.  Download CEPR discussion paper 19856, Geoeconomics https://cepr.org/publications/dp19856

Getting accepted to an elite PhD programme with a superstar advisor seems like “making it” if you want a research career in economics. But is it? How productive will those young, talented economists become? Half of elite economics PhDs from programmes at MIT, Harvard, Stanford and similar institutions publish next to nothing in the six years after they get their doctorate, and only 10% publish more than a paper or two. Josh Angrist of MIT & Marc Diederichs, University of Passau have studied what they call the economics PhD education production function at elite universities in the US. Tim Phillips asks them how, if these elite programmes are designed to create scholars who go on to publish their research consistently, can the institutions or their advisors do a better job of helping that to happen?

What gives a life meaning? Is it about health, friends, family or something else? Do rich people have more meaningful lives than poor people? Do we find meaning in success or problems and failures too? During the Great Depression, the US Government Federal Writers’ Project dispatched a team of writers across the US with a simple brief: talk to people about their lives. The archive that they created, called American Life Histories, tells us what thousands of people across the US found meaningful in their lives. A new project uses artificial intelligence to discover what these documents reveal about the meaning of life. David Lagakos of Boston University, and Hans-Joachim Voth of the University of Zurich are two of the authors. They talk to Tim Phillips about what they discovered, and the message for those of us who seek meaning in our lives today.  Read the Discussion Paper https://cepr.org/publications/dp19885 American Life histories at the Library of Congress https://www.loc.gov/collections/federal-writers-project/about-this-collection/

President Trump, aided by DOGE under Elon Musk, promised deep cuts to the US federal bureaucracy. In these cases, and many others in recent history, populist politicians complain about a bloated and unelected “administrative state” that they inherit from a previous regime. They say these public employees frustrate their ability to deliver on their promises. Others argue that a bureaucracy contains the experts that are needed to make policy function smoothly – and removing them will make government function less, not more, efficiently. So how do populists typically deal with their bureaucrats, and what are the consequences? An analysis of Italian local politics that was published recently might help us to understand what is happening in the US now, and what might happen next. Matia Vannoni of King’s College London was one of the authors. He talks to Tim Phillips about what happens when we expel the experts.

Willem Buiter, a former Chief Economist at Citigroup and ex-member of the Bank of England's Monetary Policy Committee, dives deep into the complex dynamics between central banks and governments.

Do you and your boss see the world in the same way and how does that affect your performance at work? You might not agree with your boss about everything. But if you and your boss don’t have the same outlook, does this mean you will be less productive? Alexia Delfino of Bocconi University measured both the values and the performance of employees at a global bank. She tells Tim Phillips whether shared values mean better outcomes – and what this means for diversity and team building.

Recorded at the CEPR Paris Symposium. The menopause can be a huge biological shock to women, but there has been almost no research into the consequences for their working lives. A new study uses administrative data from Norway and Sweden to discover the consequences of the menopause, both for health and for earnings. Rita Ginja of the university of Bergen tells Tim Phillips about the surprising size and persistence of the menopause penalty, and the difference that education and choice of career can make.
