    S9 Ep60: The challenges to the international financial system
    Oct 23 2026
    The 29th Geneva Report on the World Economy examines three pressures on the international financial system at once: global imbalances, the status of the dollar, and the stability of bond markets. Two of its authors, Valentina Bruno (American University, CEPR) and Cédric Tille (Geneva Graduate Institute, CEPR), tell Tim Phillips why stocks, the dollar and US Treasuries all fell on Liberation Day in April 2025, why that could happen again, and what we should do about it. So is this a rupture, or a transition in the world's financial system?The research behind this episode:Bruno, Valentina, Steven B. Kamin, Angel Ubide, and Cedric Tille. 2026. "Changing Structure and Challenges of the International Financial System: Imbalances, Currencies, and Financial Stability." Geneva Reports on the World Economy 29.

"The challenges to the international financial system”. VoxTalks Economics (podcast).About the guestsValentina Bruno is Professor of Finance at the Kogod School of Business, American University, where she holds the Arlene R. and Robert P. Kogod Eminent Scholar Chair in Finance. She is a Research Fellow of the Centre for Economic Policy Research in the Banking and Corporate Finance programme. Her research spans macroeconomics and finance, with recent work on how the US dollar transmits global financial conditions. She has worked at the World Bank and been a visiting scholar at the Federal Reserve Board.Cédric Tille is Professor of International Economics at the Geneva Graduate Institute, where he heads the Bilateral Assistance and Capacity Building for Central Banks programme. He is a Research Fellow of CEPR in the International Macroeconomics and Finance programme. His research spans financial globalisation, the dynamics of countries' external assets and liabilities, and the currencies used to invoice international trade. He sat on the Bank Council of the Swiss National Bank from 2011 to 2023 and previously worked for nine years at the Federal Reserve Bank of New York.Research cited in this episodeThe triple decline of April 2025. After the US announced sweeping tariffs on 2 April 2025, which President Trump called "Liberation Day", US stocks, Treasuries and the dollar fell together. Bruno argues that foreign investors did not sell their US assets; they bought protection against a falling dollar, and that hedging pushed the currency down. Much of their US equity exposure remains unhedged, so a new shock that starts in the US could trigger the same response.Global imbalances. Large and persistent current account surpluses in some countries, mirrored by deficits in others. Imbalances were a major policy topic before 2008, faded after the global financial crisis, and are now back. Tille argues that the headline measures have risen only modestly; the concern is China, whose trade surplus is the largest ever recorded as a share of world GDP.The China shock. Autor, David H., David Dorn, and Gordon H. Hanson. 2013. "The China Syndrome: Local Labor Market Effects of Import Competition in the United States." American Economic Review 103 (6): 2121-2168. Cheap imports from China benefited US consumers as a whole, but the job losses were concentrated in particular industries and places, furniture making among them. Tille uses it to explain why Germany's car workers see the current wave of Chinese competition differently from German consumers.The coordinated policy package. International Monetary Fund. 2026. "2026 External Sector Report: Amid Rising Imbalances, the Case for Rebalancing." The standard prescription is US fiscal consolidation, more consumption in China and more investment in Europe. The report cites IMF estimates that a coordinated package would narrow global imbalances by 0.5% of world GDP over the medium term, compared with a widening of 0.4% under current trends. Nearly all the narrowing comes from China.The renminbi debate. Brad Setser of the Council on Foreign Relations argues that China holds its exchange rate down and that a stronger renminbi is part of the solution. Tille notes that other economists treat the exchange rate as a sideshow to China's high savings and weak domestic demand.The basis trade. Pension funds, insurers and asset managers often prefer to hold Treasury exposure through futures. Hedge funds take the other side; they sell the futures, buy the bonds and earn the small gap between the two prices, funded with overnight borrowing. In calm markets the trade links the futures and cash markets and helps the Treasury sell its debt. When lenders pull back, hedge funds must sell bonds at the same moment. The report cites estimates that Cayman Islands hedge funds alone held about $1.8 trillion of Treasuries.March 2020 and the UK gilt crisis. In March 2020, the Covid shock set off a scramble for ...

    S9 Ep59: Life after divorce
    Oct 16 2026
    Who gets the kids? Courts aim to decide custody in the child's best interests, but nobody has had the data to test how well those decisions work.Gordon Dahl (UC San Diego, CEPR), Costas Meghir (Yale, CEPR) and seven co-authors built the data themselves. They collected more than 56,000 Swedish custody rulings, scanning paper files by hand where no digital copy existed, and linked them to records of parents' earnings, prescriptions and children's school tests. It seems Swedish judges do not agree on how often to award joint custody. Some award it in about 60% of cases; others in about 20%. But that decision makes a huge difference to the lives, and happiness, of both parents and children. They tell Tim Phillips whether joint or sole custody has, on average, better outcomes.The research behind this episode:Canessa, Stella, Gordon Dahl, Anna Hasselqvist, Costas Meghir, Susan Niknami, Marten Palme, Helmut Rainer, Olof Rosenqvist, and Pengpeng Xiao. 2026. "Life After Divorce: Effects of Joint Custody on Parents and Children." CEPR Discussion Paper 21780. To cite this episode:Phillips, Tim, Gordon Dahl, and Costas Meghir. 2026. "Life after divorce." VoxTalks Economics (podcast). About the guestsGordon Dahl is Professor of Economics at the University of California, San Diego, and a Fellow in the Labour Economics programme of the Centre for Economic Policy Research. His research spans the family, public policy and the labour market, including how family income shapes children's achievement, peer effects among co-workers and family members, the effects of incarceration on employment, and how welfare use passes between generations.Costas Meghir is the Douglas A. Warner III Professor of Economics at Yale University and a CEPR Fellow in the Labour Economics, Development Economics and Public Economics programmes. His research spans labour supply and welfare programmes, marriage markets and how resources are shared within households, informal labour markets, and early childhood development.Research cited in this episodeThe best interests of the child standard. Since the 1970s, most custody law has told judges to decide in the child's best interests rather than weigh the parents' claims. Most countries now read this as keeping both parents involved, which is why joint custody is the default in many jurisdictions. The standard leaves wide discretion to judges, and Meghir says judges get little systematic evidence on what works. Elizabeth Scott and Robert Emery examine why the standard has persisted despite this criticism in "Gender Politics and Child Custody: The Puzzling Persistence of the Best-Interests Standard" (Law and Contemporary Problems, 2014).The tender years doctrine. Before the mid-19th century, English law treated children as their father's property. The Custody of Infants Act 1839, passed after a campaign by Caroline Norton, let mothers petition for custody of children under seven, and the presumption that young children belong with their mother spread across Europe. Dahl raises it to show how far the legal default has moved in less than two centuries, from father, to mother, to both.Random assignment of judges. Families who end up with joint custody differ from those who do not, so a simple comparison cannot separate the effect of the arrangement from the effect of the family. In Sweden, custody disputes go to judges at random, and judges differ in how often they award joint custody. Comparing families who drew a lenient judge with families who drew a strict one isolates the effect of the ruling itself. Economists have used the same design to study prison sentences, for example Jeffrey Kling in "Incarceration Length, Employment, and Earnings" (American Economic Review, 2006). The method only measures effects for cases where judges could disagree; it says nothing about cases where every judge would reach the same decision.Swedish court archives. Custody rulings are public records in Sweden, but no national database holds them. The authors requested files from all 48 district courts and received documents from 45. Digital archives covered cases from about 2010; for earlier years, the team visited court archives and scanned 19,491 paper rulings by hand. Dahl estimates that 80% of the project's time went on collecting data.Swedish administrative registers. Statistics Sweden registers cover the whole population and record earnings, employment, family links and place of residence. The authors linked these to prescription records, which show who takes antidepressant, anti-anxiety and ADHD medication, and to records of intimate partner violence. This is why the research could follow mothers, fathers and children for years after each ruling.National tests and school quality. All Swedish pupils sit the same national tests in Swedish and mathematics in grades three, six and nine. The authors use these scores to measure children's achievement, and build a measure of school quality from how much better or worse a ...

    S9 Ep58: Not wearing Prada
    Oct 9 2026
    Since March 2022, it has been harder to buy an iPhone in Russia, because Apple chose to stop selling there. So did Prada, Renault, Starbucks, Nike and more than 1,000 other firms. These private sanctions added to the official sanctions imposed by 45 countries.Beata Javorcik (EBRD, Oxford, CEPR) and her co-authors wanted to know if private sanctions did anything more than generate good headlines. To do this, they matched millions of Russian customs records to the trademarks on the goods, so they could tell an iPhone from a Samsung phone and a Gucci scarf from a Gucci bag. Would imports of goods under voluntary sanctions stop? Would the brands cheat? Would importers find an other way to get goods into the country through the back door? She tells Tim Phillips what private sanctions on Russia have achieved.The research behind this episode:Chupilkin, Maxim, Beata Javorcik, Alexander Plekhanov, and Aleksandra Peeva. 2026. "Not Wearing Prada: Do Private Sanctions Reinforce Official Sanctions?" CEPR Discussion Paper 21774. To cite this episode:Phillips, Tim, and Beata Javorcik. 2026. "Not wearing Prada." VoxTalks Economics (podcast).About the guestBeata Javorcik is Chief Economist of the European Bank for Reconstruction and Development, on leave from the University of Oxford, where she is Professor of Economics and a Fellow of All Souls College. She is a Fellow of the Centre for Economic Policy Research in the International Trade and Regional Economics programme. Her research spans foreign direct investment, shocks to production networks, trade under sanctions and the evasion of import duties.Research cited in this episodeOfficial sanctions on Russia. After the full-scale invasion of Ukraine in February 2022, 45 economies, including the US, the EU and the UK, imposed sanctions on Russia. They cut selected Russian banks off from the SWIFT payment messaging system, immobilised the reserves of Russia's central bank, limited Russia's earnings from hydrocarbon exports and banned exports of arms, dual-use goods, advanced technology, industrial equipment and luxury goods. By the end of 2022, around 40% of product lines were at least partly covered. The luxury ban explains some odd entries. Ski suits and sports clothing priced above €300 are sanctioned, and champagne is banned while prosecco is not. Enforcement sits with several bodies: in the US, the Office of Foreign Assets Control and the Commerce Department; in the EU, individual member states; in the UK, the Office of Financial Sanctions Implementation and the Office of Trade Sanctions Implementation.Private sanctions and public opinion. Oliver Hart, David Thesmar and Luigi Zingales surveyed 2,915 Americans, a representative sample, in May and June 2022. Of these, 61% agreed that doing business in Russia is like being an accomplice to the war, and that firms should sever ties whatever the consequences. Javorcik raises the study to explain why firms with no legal obligation to leave Russia chose to go anyway: reputation, the threat of boycotts, pressure from investors, employees and business partners, and sometimes the values of managers. Hart, Oliver, David Thesmar, and Luigi Zingales. 2024. "Private Sanctions." Economic Policy 39 (117): 203-268."The business of business is business." The phrase is a popular summary of the view Milton Friedman set out in a 1970 essay in the New York Times Magazine, "The Social Responsibility of Business Is to Increase Its Profits." Hart and his co-authors found that only a minority of their respondents treated the decision to leave Russia as a purely commercial one.The Yale list. A team at the Yale Chief Executive Leadership Institute, led by Jeffrey Sonnenfeld, has tracked what more than 1,500 major companies said about their Russian operations since the invasion. To qualify, a firm must have revenue above $100 million, be majority owned from outside Russia and Belarus, and have meaningful operations in its home country, in Russia and in at least one other country. The team grades firms from full withdrawal to "digging in," and keeps a separate record of firms that reneged on their promises to leave. Javorcik and her co-authors use the list to classify the owners of 1,657 Western trademarks. Only 11 firms moved from strict private sanctions to doing little or nothing.Customs data with trademarks. The paper draws on transaction-level records of Russian imports from 2016 to 2023, about 12 million records in 2022 alone. Each record shows the product code, the value, the quantity, the trading partner and the trademark. The products are classified at the six-digit level of the Harmonized System, which has more than 5,600 categories. The trademark field contained more than 1.2 million spellings; the authors used a large language model to standardise them, which merged 600 versions of "Samsung" into one.Trade diversion through neutral countries. Countries that do not participate in sanctions, including China, Turkey and the UAE, do ...
