Planet Money - Twins (classic)

Twins are used to fielding all sorts of questions, like "Can you read each other's minds?" or "Can you feel each other's pain?" Two of our Planet Money reporters are twins, and they have heard them all.

But it's not just strangers on the street who are fascinated by twins. Scientists have been studying twins since the 1800s, trying to get at one of humanity's biggest questions: How much of what we do and how we are is encoded in our genes? The answer to this has all kinds of implications, for everything from healthcare to education, criminal justice and government spending.

Today on the show, we look at the history of twin studies. We ask what decades of studying twins has taught us. We look back at a twin study that asked whether genes influence antisocial behavior and rule-breaking. One of our reporters was a subject in it. And we find out: are twin studies still important for science?

Our show today was hosted by Sally Helm and Karen Duffin. It was produced by Darian Woods and Nick Fountain. It was edited by Bryant Urstadt.

Planet Money - The 60-day job race

People come from all over the world to work in U.S. tech. And during the tech boom years, the industry relied heavily on foreign workers. This is how we built Silicon Valley – with great minds coming from everywhere to work in the U.S.

But when the industry started to shrink, all of these people who moved here for work are finding that linking their jobs to their residency is really complicated. That was the case for Aashka and Nilanjan. Aashka was a product engineer at Amazon, and Nilanjan worked in digital advertising for Google. They both lost their jobs in the layoffs each company announced earlier this year.

When Aashka and Nilanjan got the news, a clock started ticking. Because they are both H-1B recipients, they only have 60 days to find new jobs before they risk being sent home. And they can't get just any job – they need new employers in their field willing to sponsor their visa.

On today's show, we followed two tech workers as they tried to find jobs before their visas expired, and what they went through as H-1B recipients trying to stay in the country.

This episode was hosted by Alyssa Jeong Perry and Amanda Aronczyk, produced by Sam Yellowhorse Kesler, engineered by James Willetts, fact-checked by Sierra Juarez, and edited by Molly Messick and Jess Jiang.

Planet Money - Two Indicators: The economics of innovation

Innovation is crucial for game-changing advancements in society, whether it's treatments for serious diseases, developments in AI technology, or rocket science.

Today on the show, we're airing two episodes from our daily economics show The Indicator. First, a new paper suggests that breakthrough innovations are more likely at smaller, younger companies. We talk to an inventor who left a big pharmaceutical company to start afresh, leading to some incredible treatments for serious diseases.

Then, it's off to Mars — or at least, on the way. Elon Musk's company SpaceX did a first test launch of a rocket meant to go all the way to the red planet. The rocket made it up off of the launch pad and lumbered briefly through the sky before self-destructing over the Gulf of Mexico. Suffice it to say, it's not quite ready. NPR science correspondent Geoff Brumfiel walks us through SpaceX's business plan as we try to figure out if this company has the funding and business acumen to reach its moonshot goal.

These two Indicator episodes were originally produced by Corey Bridges & Brittany Cronin, engineered by Katherine Silva & James Willets, and fact-checked by Dylan Sloan & Sierra Juarez. Kate Concannon edits the show.

The Planet Money version of this episode was produced by Willa Rubin, engineered by Robert Rodriguez, and edited by Keith Romer.

Hayek Program Podcast - Civil Society — Lenore Ealy on Philanthropy and Social Design

On this episode of the Hayek Program Podcast, we continue our three-part miniseries on Civil Society, hosted by Mikayla Novak who explores civil society, encompassing the practical nature of voluntary mutual assistance outside but entangled with the domains of market and state, the theoretical dimensions of civil society, and the intersection of classical liberalism and civil society.

Joining Novak for this episode is Lenore Ealy, vice-rector internacional at Universidad Francisco Marroquín in Guatemala, discussing the history of philanthropy and social design. Ealy begins by describing her work with Richard Cornuelle, sparking Ealy’s early interest in understanding philanthropy, the history of civil society, and liberal individualism. She examines the role of government involvement in nonprofit organizations, learned helplessness, and the problems afflicting philanthropy. She elaborates on our inability to successfully construct an organized social design, referring to the work of Vincent and Elinor Ostrom. Novak and Ealy also discuss ideas of self-scoring poverty, whether humans have a natural desire for freedom, and the meaning of “civil society.”

Lenore Ealy is vice-rector internacional at Universidad Francisco Marroquín in Guatemala, founding president of The Philanthropic Enterprise, and co-editor of numerous books including the book series, Polycentricity: Studies in Institutional Diversity and Voluntary Governance. Ealy holds a PhD in the history of moral and political thought from John Hopkins University.

Planet Money - The town that changed economics

In the early 90s, when a young economist named Michael Kremer finished his PhD, there had been a few economic studies based on randomized trials. But they were rare. In part because randomized trials – in which you recruit two statistically identical groups, choose one of them to get a treatment, and then compare what happens to each group – are expensive, and they take a lot of time.

But then, by chance, Michael had the opportunity to run a randomized trial in Busia, Kenya. He helped a nonprofit test whether the aid they were giving to local schools helped the students. That study paved the way for more randomized trials, and for other economists to use the method.

On today's show, how Busia, Kenya, became the place where economists pioneered a more scientific way to study huge problems, from contaminated water to low graduation rates, to HIV transmission. And how that research changed government programs and aid efforts around the world.

Planet Money - The Spider-Man Problem (update)

(Note: This episode originally ran back in 2022.)

This past weekend, Spider-Man: Across the Spider-Verse had the second largest domestic opening of 2023, netting (or should we say webbing?) over $120 million in its opening weekend in the U.S. and Canada. But the story leading up to this latest Spider-Man movie has been its own epic saga.

When Marvel licensed the Spider-Man film rights to Sony Pictures in the 1990s, the deal made sense — Marvel didn't make movies yet, and their business was mainly about making comic books and toys. Years later, though, the deal would come back to haunt Marvel, and it would start a long tug of war between Sony and Marvel over who should have creative cinematic control of Marvel's most popular superhero. Today, we break down all of the off-screen drama that has become just as entertaining as the movies themselves.

This episode was originally produced by Nick Fountain with help from Taylor Washington and Dave Blanchard. It was engineered by Isaac Rodrigues. It was edited by Jess Jiang. The update was produced by Emma Peaslee, with engineering by Maggie Luthar. It was edited by Keith Romer.

Planet Money - AI Podcast 3.0: Dial M for Mechanization

It's the thrilling conclusion to our three-part series on AI — the world premiere of the first episode of Planet Money written by AI. In Part 1 of this series, we taught AI how to write an original Planet Money script by feeding it real research and interviews. In Part 2, we used AI to clone the voice of our former colleague Robert Smith.

Now, we've put everything together into a 15-minute Planet Money episode. And we've gathered some of our co-hosts to listen along.

So, how did the AI do? You'll have to listen to learn what went surprisingly well, where it fell short, and hear reactions from the real-life hosts whose jobs could be at risk of being replaced by the machines.

This episode was produced by Emma Peaslee and Willa Rubin. It was engineered by James Willetts and fact-checked by Sierra Juarez. Keith Romer edited this series and Jess Jiang is our acting executive producer.

In the radio play, Mary Childs voiced Ethel Kinney; Willa Rubin voiced Alice; and Kenny Malone voiced Dr. Jones and Dial Doom 5000.

Planet Money - AI Podcast 2.0: The host in the machine

In Part 1 of this series, AI proved that it could use real research and real interviews to write an original script for an episode of Planet Money. Our next task was to teach the computer how to sound like us. How to read that script aloud like a Planet Money host.

On today's show, we explore the world of AI-generated voices, which have become so lifelike in recent years that they can credibly imitate specific people. To test the limits of the technology, we attempt to create our own synthetic voice by training a computer on recordings of former Planet Money host Robert Smith. Then we introduce synthetic Robert to his very human namesake.

There are a lot of ethical, and economic, questions raised by a technology that can duplicate anyone's voice. To help us make sense of it all, we seek the advice of an artist who has embraced AI voice clones: the musician Grimes.

This episode was produced by Emma Peaslee and Willa Rubin, with help from Sam Yellowhorse Kesler. It was edited by Keith Romer and fact-checked by Sierra Juarez. Engineering by James Willetts. Jess Jiang is our acting executive producer.
