If you have money in an index fund, you are benefiting from Eugene Fama's work. In this Extra Slice of The Pie, the Nobel laureate and "father of modern finance" reflects on a career that reshaped how trillions of dollars are invested, including his development of the Efficient Market Hypothesis, which provides the theoretical foundation for passive investing.

Two hundred fifty years after The Wealth of Nations, capitalism looks nothing like Adam Smith imagined (and nothing like Karl Marx predicted, either). Smith envisioned small, decentralized producers, while Marx foresaw concentration dominated by the rich. In this lecture, Yueran Ma of Chicago Booth draws on centuries of global data to show how production concentrated while ownership diffused, and the giants at the top keep getting toppled.

The common perception of Chinese governance is a strong, centralized state. For decades, however, the vast majority of the country's policies  originated with local governments, as officials experimented, competed, and copied each other's successes. In this episode, Shaoda Wang of Harris Public Policy describes his research analyzing 3.7 million government documents to trace the origin and diffusion of Chinese policies, revealing the economic costs of the country's shift toward centralized policymaking.

Who bore the cost of 2025's sweeping tariffs? UChicago economist Brent Neiman returns to The Pie to discuss his new research with co-author Gita Gopinath examining the effects of last year's tariffs. Neiman reveals a gap between statutory rates and what was actually collected, explains why US importers absorbed the vast majority of costs, and discusses China's dramatic collapse as a US trading partner. He also explores the longer-term implications, including potential retaliation, shifting global alliances, and diplomatic costs that may outlast any short-term revenue gains.

Days after the Trump administration's surprise military operation captured Venezuelan leader Nicolás Maduro, a panel of UChicago scholars gathered to make sense of what it means for Venezuela, the United States, and the region. Professor Christopher Blattman, Deputy Dean Ryan Kellogg, and Associate Professor Paul Poast join moderator Rebecca Wolfe to discuss Venezuela's decline from one of the hemisphere's wealthiest nations, the regional migration crisis that followed, and the uncertain road ahead.

Financial crises are "everywhere and always" a problem of short-term debt. In this Extra Slice of The Pie, Nobel laureate Douglas Diamond explains his groundbreaking research on why banks exist in the first place, and why they're vulnerable to runs. Diamond discusses his role advising policymakers during the 2008 crisis, reflects on predicting the savings and loan disaster as a graduate student in the 1970s, and explains why the 30-year mortgage is like Michael Corleone: something good that went bad when it hung around with the wrong crowd.

Standard measures of intergenerational mobility treat parental income as a single average across childhood. In this episode, Steven Durlauf, Frank P. Hixon Distinguished Service Professor at the Harris School of Public Policy and Director of the Stone Center for Research on Wealth Inequality and Mobility, describes how parental income during the tween and adolescent years (ages 12-18) is far more predictive of adult outcomes than parental income during early childhood.

As we close out 2025, host Tess Vigeland highlights research from UChicago scholars. Hyuk Su Kwon, Assistant Professor at the Harris School of Public Policy, explains the design of electric vehicle subsidies. Eduardo Montero, Assistant Professor at Harris, reveals how Seventh Day Adventist churches adapt when members face costly trade-offs between faith and farming. Virginia Minni, Assistant Professor at the Booth School of Business, shares how a one-day purpose workshop where workers connect childhood passions to their current roles drives measurable productivity gains. Plus, Leo Bursztyn discusses why green text bubbles create lock-in effects for Apple. Full versions of these conversations are available wherever you get your podcasts.

In this wide-ranging conversation, Nobel Prize–winning economist Roger Myerson reflects on a career studying how rules shape human behavior, from optimal auction design to Ukraine's decentralization reforms. Myerson explains the foundations of mechanism design and incentive constraints, tracing economics back to Xenophon and arguing that local democracy is what holds democracies together.

Large gaps in language skills between children from different socioeconomic backgrounds emerge early and persist throughout schooling. In this episode, Ariel Kalil, Professor of Public Policy at UChicago's Harris School, discusses her research on "Chat2Learn," a technology intervention that sends open-ended conversation prompts to parents' phones. The low-cost behavioral nudge increases vocabulary, encourages back-and-forth conversation, and fosters curiosity in young children.
