What happens when one of the world’s busiest fire departments faces a catastrophe unlike anything it has experienced before?

Gregory P. Shea, Wharton Adjunct Professor of Management, and Author of Rising from Ground Zero, examines how the FDNY responded to the unprecedented challenges of 9/11.

Shea explains how the department transformed its psychological support, leadership training, incident management, and collaboration with outside agencies. The conversation explores how the FDNY turned lessons from Ground Zero into lasting organizational change and became an all hazards department.

Shared bikes and scooters have transformed how people move through cities, but can the business model actually work?

Gad Allon, Wharton Professor of Operations, Information and Decisions, explores the economics behind companies like Lime, including subscriptions, pay per trip models, utilization, and the challenges of operating across different cities.

Allon also explains why cities have embraced and restricted scooters, how Lime emerged as a dominant player, and why building a culture around shared transportation may be just as important as the technology itself.

The AI boom could transform the economy, but who is financing it and where the risks are building may matter just as much as the technology itself.

Joao Gomes, Wharton Professor of Finance and Senior Vice Dean of Research, Centers, and Academic Initiatives, argues that the Federal Reserve is too focused on inflation and not focused enough on financial stability.

Gomes discusses the opaque role of private credit, lessons from the housing crisis and internet boom, the potential impact of AI investment on long term productivity, and why the Fed needs better models for understanding the financial risks surrounding AI.

We often think of competition and collaboration as opposites. But in reality, we frequently do both at the same time.

Henning Piezunka, Wharton Associate Professor of Management, explains why competing with someone can fundamentally change how we view and work with them.

Piezunka uses World Cup soccer to examine what happens when teammates become opponents, finding that players collaborated less after competing against one another. The research offers surprising lessons for managers dealing with promotions, bonuses and other competitive workplace dynamics.

What do rising bond yields, new tariffs and soaring AI investment mean for the U.S. economy and financial markets?

Wharton Emeritus Professor of Finance and WisdomTree Senior Economist Jeremy Siegel joins the conversation to assess the latest economic and market developments.

Siegel discusses the impact of higher tariffs on Canada and Mexico, why rising Treasury yields are signaling concern about U.S. deficits, and why he believes Washington may eventually be forced to take action on fiscal policy.

He also weighs in on the resilience of the stock market, the extraordinary performance of AI-related companies, and what could determine whether equities reach new highs in the months ahead.

The bond market is sending a warning to the Federal Reserve. With long-term yields climbing to levels not seen in decades, questions are mounting about the Fed’s ability to control inflation while maintaining market confidence.

Wharton Finance Professor Nikolai Roussanov explains why Kevin Warsh’s recent messaging has unsettled investors and why the Fed’s reaction function may matter more than its guidance on the path of interest rates.

Roussanov also examines the tension between monetary and fiscal policy, including whether Treasury efforts to push down long-term yields could undermine the Fed’s strategy.

As inflation, energy prices and fiscal pressures evolve, the Fed faces a critical test: preserve its 2% inflation target—or risk losing credibility with the bond market.

What happens when the systems designed to keep our food safe start to break down?

Corinne Low, Wharton Associate Professor of Business Economics and Public Policy, argues that food safety is a public good—one that individuals and families simply can't provide for themselves.

She explains how reduced staffing, weakened inspections and changes to disease surveillance can leave consumers more vulnerable to foodborne illness.

Low also examines what happens when that responsibility gets pushed onto parents, and why trusting companies to regulate themselves isn't enough.

The result is a larger question about government, business and the basic protections consumers should be able to count on.

AI is advancing rapidly—but who is responsible when the risks become too big to ignore?

Peter Conti-Brown, Professor at the Wharton School, explores whether the banking system offers a useful model for supervising powerful AI companies.

Rather than relying solely on rules written years in advance, bank supervision involves ongoing conversations between public officials and private institutions to identify and manage emerging risks.

Conti-Brown discusses how AI stress tests could work, what might happen if powerful models are hijacked or misused, and why consumers could ultimately end up holding the bag when things go wrong.

Why are more young Americans turning to entrepreneurship, and what role will AI play?

Lori Rosenkopf, Vice Dean of Entrepreneurship at the Wharton School, explores how Gen Z’s shifting expectations, a tougher entry-level job market, and the desire for flexibility are reshaping career paths. She also examines how AI tools are making it easier to turn ideas into products while intensifying competition, and what venture capital, failure, the creator economy, and programs like VentureLab can teach aspiring founders.

As AI becomes more powerful, who should be responsible for governing it?

Kevin Werbach, Wharton Professor and Chair of Legal Studies and Business Ethics, explores the growing challenges of AI governance, from accountability and safety to the difficulty of creating effective regulations across countries. He explains why AI companies can't be expected to regulate themselves and why governments need to play a more constructive role in managing the risks of increasingly powerful AI.
