The Millionaires Hiding in Plain Sight
The Millionaires Hiding in Plain Sight Oct 8, 2026 00:32:46 Over a decade ago, Eric Zwick got assigned an unusual project at the U.S. Treasury: Find out how much tax businesses were paying. But the data was a mess, so Eric and two friends helped comb through it and, in doing so, got to build a topographic map of business activity and profitability in America. And it suddenly revealed a class of people who had been hard to see before: the “everywhere millio

Why Being Unpopular is Expensive for Countries
Why Being Unpopular is Expensive for Countries Sep 24, 2026 00:37:33 Being a country’s central banker is a technical job. But, just like high school, if you are a popular central banker, it pays off. Aditi Sahasrabuddhe is a political scientist at Brown University, and has researched just how much it pays to be popular. It’s the kind of question that the field of economics largely neglects. Aditi looks at central-bank-likeability through the manifestation of swap l
Emily Oster Doesn't Mind the Haters
Emily Oster Doesn't Mind the Haters Sep 17, 2026 00:41:15 Emily Oster is not a doctor. She’s an economics professor at Brown University, and for years she’s been applying her economics lens and ability to read studies and analyze data to help decode health research. Her conclusions sometimes produce runaway hits – as in Expecting Better, her book upending the “conventional pregnancy wisdom” – and at other times are wildly unpopular – as with her recommen
The Bond Market Rules Everything Around Me/You/Us
The Bond Market Rules Everything Around Me/You/Us Sep 10, 2026 00:40:20 Bonds around the world have been selling off, kind of a lot. And that selloff has sent interest rates on government debt to or near their highest in decades— for US government debt, but also debt from the UK, Germany, France, Japan. What gives? We pulled in one of the people who buys and sells those bonds, Ed Al-Hussainy, at Columbia Threadneedle, which manages a lot of money for other people and
Why do we love gold so much?
Why do we love gold so much? Sep 3, 2026 00:38:32 Gold was on a tear in August. People, investors, and central banks around the world were buying more and more, in large part because it’s seen as a stable alternative to the dollar, or to any currency. But…why? Why gold? What makes it so special? Friend of the show Jacob Goldstein wrote a book called Money: The True Story of a Made-Up Thing, and he explains the real, physical reasons why we love g
What Should Not Be For Sale?
What Should Not Be For Sale? Aug 27, 2026 00:41:04 If you live in the worlds of financial markets and economics, sometimes it can be hard to remember that not all of life can be neatly packaged into data points and lists of pros and cons. And Nobel-Prize-winning-economist and Stanford professor Al Roth is pretty convincing that markets are Good, and that, if you think it through, we *should* allow some kind of market in the trade of *some* human o
AI and Alienation
AI and Alienation Aug 20, 2026 00:40:59 AI is creating unfathomable wealth for a handful of people, upending labor markets, and jacking up electricity bills for the rest of us. But somehow we have to figure out how to still be a society. We’ve done it before – AI is just the latest "General Purpose Technology" we have to adapt to. Many of the vectors we worry about here are even more pronounced abroad – visible inequality, inconsistent
The AI Hedge Fund Implosion That Wasn't
The AI Hedge Fund Implosion That Wasn't Aug 13, 2026 00:40:26 At the end of July, you may have heard the sound of a hedge fund blowing up. Situational Awareness, a fund focused on the new AI world, had a sudden firesale of its holdings. It seemed like an AI bubble barometer—a way to tell whether the markets have gone too far. Amelia Pollard, investment correspondent at the Financial Times, has been breaking stories on the drama every step of the way. And she
How to Get to Sesame Street
How to Get to Sesame Street Aug 6, 2026 00:39:56 Making educational content for kids is fun, but also really hard to do well. Kids are not an ideal audience: they are prone to wandering away, getting distracted, not remembering the plot. Scott Cameron is the head of content & IP strategy at Sesame Workshop, which makes the beloved and long running show Sesame Street. We were curious what makes kid’s content good, what it can achieve, and what Se
AI can do it all. Chat, is that bad?
AI can do it all. Chat, is that bad? Jul 30, 2026 00:31:43 Jae Woo Lee loves coding. To him, it’s an art form, like poetry. He’s a legendary professor of computer science at Columbia, where he teaches advanced programming to hundreds of students a year. Which means he’s on the front lines of the war between AI and education. And what he is seeing…is not exactly heartening. He tells us why coding by hand is still an art worth learning, why it’s still impor

What is the International Criminal Court and why are "we" "dismantling" it? Jul 24, 2026 00:40:42 The US Secretary of State Marco Rubio just announced his intention to “dismantle” the International Criminal Court “brick by brick.” Which raised some important questions. Like, what IS the ICC, actually? Where did it come from, and what power does it have? Why does the US want to dismantle it, and is that even possible? We sit down with Maria Elena Vignoli, a lawyer at Human Rights Watch who call
