As this podcast has highlighted before, cross-disciplinary collaboration can enrich practically any investigation into the nature of inequality. It is hard to find more compelling evidence of this than recent breakthroughs in the study of wealth inequality.

Today on the show, we speak to two experts who have made fundamental contributions to this literature, in part by drawing on physics, math, and even Renaissance-era history.

Our first guest is Alberto Bisin. Alberto is a professor of economics at New York University. He joins host Steven Durlauf to discuss how models of wealth inequality have evolved over time, as well as how recent models have successfully incorporated tools from the physics literature.

Expanding on those insights from physicists, in our second segment, Steven speaks with Jean-Philippe Bouchaud. A physicist and mathematician by training, Jean-Philippe has long been a pioneer of “econophysics,” and his work consistently reveals novel, eye-opening ways economists can supplement their work using physics and math.

College athletics has tumbled into an unpredictable era. Money paid to players for their name, image and likeness has shaken long-held assumptions about what it means to be a college athlete. But although NIL deals have kicked off a new era in college sports, the tensions and conflicts involved are nothing new — nor are they unique to college athletics.

Today on the show, we present a conversation that places the debate around paying college athletes into a broader context, drawing on the work of our esteemed panelists. The discussion, which was recorded live on stage earlier this year, features sports analyst Bomani Jones; Princeton Professor of Economics and Stone Center Affiliate Ilyana Kuziemko; Booth Professor of Economics Matthew J. Notowidigdo; and Professor Emeritus at the Wharton School of the University of Pennsylvania Kenneth L. Shropshire. Damon Jones, Stone Center Associate Director and one of our show’s co-hosts, moderates the panel.

One of the most pernicious drivers of inequality in the United States over the past half century has been mass incarceration. Moreover, the consequences of mass incarceration have been borne not just by those held in prisons, but by their families and communities as well.

First, Harvard sociologist Christopher Muller traces the historical roots of mass incarceration. He illuminates the close association between incarceration rates and the demand for labor, a relationship that has persisted from the 19th century American South down through the present day.

Then, Duke sociologist Hedy Lee discusses her work on the oft-overlooked effects of mass incarceration on the families of incarcerated people. From the mental toll on spouses and children, to the nickel-and-diming of prison commissaries, the conversation catalogs a wide array of unexpected costs brought on by mass imprisonment.

Inequality is rarely static. It can grow or shrink over time. Perhaps no one understands that dynamic better than economist Bhash Mazumder, whose work has been foundational in understanding and measuring intergenerational mobility.

In this conversation with host Steven Durlauf, Bhash recounts how his research revealed a clearer picture of income mobility in the United States: namely, how previous estimates of mobility were far too rosy. Throughout their discussion, measurement issues abound. They consider typical metrics such as income and wealth, but also less obvious approaches, including surveys of physical and mental health. Last, they discuss how mobility has been shaped by two major events in American history: first, redlining policies that began during the New Deal, and second, urban renewal projects that were sparked by the Great Migration.

Conversations about inequality tend to center on macro-level forces, such as political, economic, and social systems. But today on the show, we present two conversations that examine factors that unfold on a smaller scale: inside people’s everyday domains.

In our first segment, host Steven Durlauf interviews fellow host Ariel Kalil, a developmental psychologist at the University of Chicago, about her work on family structure and the ways it can influence inequality. They drill down on the roles extended family members like grandparents play in raising children, how growing up with a single parent appears to have a more pronounced effect on boys, and how economic scarcity can hamper parents’ ability to give attention to their children.

After that, Ariel and Steven speak with Mesmin Destin, a developmental psychologist at Northwestern. Drawing on research into identify formation, including the damaging effects of stereotype threat, Mesmin’s work explores identity-based motivation. The group considers various applications of this concept and how it may help alleviate inequality, including interventions that can help young people develop positive beliefs that are specific to their background and the benefits peer-to-peer mentorship programs.

Neighborhoods and schools—through factors like socioeconomic composition, access to resources, racial segregation, and social networks—contribute to patterns of inequality and influence mobility. Today’s guests provide cross-disciplinary insights into how these environments shape opportunities and outcomes.

First, host Steven Durlauf speaks with the University of Wisconsin’s Felix Elwert, UC Berkeley’s David Harding, and the Stone Center’s own Geoffrey Wodtke on their research, which investigates neighborhood effects and how they manifest throughout economic and social systems, with a spotlight on segregation in schools.

Their discussion is followed by a conversation with Columbia University’s Marissa Thompson, who studies education’s role in shaping inequality. She shares her findings with hosts Geoffrey Wodtke and Damon Jones on how parents form their perceptions of neighborhood schools, how those perceptions can drive segregation, and what policy interventions might make a difference.

On this episode of The Inequality Podcast, host Steven Durlauf is joined by Janet Gornick, director of the Stone Center of Socio-Economic Inequality at The City University of New York and one of the world’s foremost experts on the measurement of socio-economic inequality. They discuss her many contributions to improving the quantity and quality of inequality data available to researchers, including her time as director of LIS, the organization formerly known as the Luxembourg Income Study. The importance of data-gathering efforts like LIS remains front and center as the conversation progresses into a discussion of gender inequality and differences in family structures across countries. Last, the two reflect on the importance of an interdisciplinary approach to social science research and consider what questions new scholars should pursue in the future.

In the first episode of the new academic year, Steven sits down with Miles Corak to discuss cross-country comparisons of inequality and intergenerational mobility. They discuss the Great Gatsby Curve, the mechanisms behind the intergenerational persistence of socioeconomic status, and related innovations in economic research and policy in the U.S. and Canada.

Since the 1970s, two-parent households have declined, while single-parent households have become more commonplace in the United States. This shift has occurred due to various factors, ranging from changes in labor markets, mass incarceration, and changing social norms surrounding marriage and parental responsibilities. In her book “The Two-Parent Privilege,” Melissa Kearny explores how this shift in family structure is related to childhood outcomes. Kearney argues that resources and stability afforded by a two-parent household yield significantly better outcomes: their children are much more likely to graduate high school, get a college degree, and have high earnings in the job market as adults. By contrast, children who grow up in single-parent households have substantially lower chances of such a life trajectory and are likely to raise their children alone. These empirical regularities have natural public policy implications.

Join University of Maryland Professor Melissa Kearney to discuss her new book and how modern trends in family structure perpetuate inequality and erode social mobility. Geoffrey Wodtke, Associate Director of the Stone Center, moderates the discussion. Steven Durlauf, Director of the Stone Center, Damon Jones, an Associate Director of the Stone Center, and Ariel Kalil, a Stone Center Advisor, offer expert commentary. This event aims to present its audience with evidence of the effects of family structure on childhood outcomes and to explore public policies to strengthen the potential for two-parent households while making the consequences of single-parent households less onerous.

This event was recorded on November 29th, 2023.

The 2023 Supreme Court decision in Students for Fair Admissions v. Harvard and UNC struck down race-based college admissions. It reignited debates about affirmative action as a tool for addressing inequality and historical injustice. In an interview recorded live at the Harris School of Public Policy in November, Stone Center Director Steven Durlauf and Brown University economist Glenn Loury discuss their different perspectives on affirmative action. Ethan Bueno de Mesquita, Interim Dean of the Harris School, moderates the event.

This is the first installment of a series of Conversations on Inequality. These conversations aim to present audiences with arguments on both sides of a complex and nuanced issue with the hope of fostering a citizenry able to evaluate opposing perspectives critically and make informed decisions.
