Planet Money

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?(Note: This episode originally ran in 2019.)Our show today was hosted by Sally Helm and Karen Duffin. It was produced by Daria

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 throu

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 e

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. This episode was produced by James Sneed with help from Willa Rubin. It

(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'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.He

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.

We used to think some jobs were safe from automation. Though machines have transformed industries like agriculture and manufacturing, the conventional wisdom was that they could never perform what's called "knowledge work." That the robots could never replace lawyers or accountants — or journalists, like us.Well, ever since the release of artificial intelligence tools like ChatGPT, it feels like no job is safe. AI can now write essays, generate computer code, and even pass the bar exam. Will work ever be the same again?Here at Planet Money, we are launching a new three-part series to understand what this new AI-powered future looks like. Our goal: to get the machines to make an entire Planet Money show. In this first episode, we try to teach the AI how to write a script for us from scratch. Can the AI do research for us, interview our sources, and then stitch everything together in a creative, entertaining way? We're going to find out just how much of our own jobs we can automate — and what work might soon lo

Lyle Jack wants to build a wind farm on the Pine Ridge Reservation in South Dakota. But to make the project work, he has to connect that wind farm to the electric grid. Which is easier said than done. On today's show - how the green energy revolution may live, or die, by bureaucrats trying to untangle a mess of wires. This episode was produced by Willa Rubin.

It's time for another installment of ... Planet Money Predictions! *air horn* Last year, we invited two economic forecasters to tell us what they saw coming for jobs, the housing market, and inflation. And now they're back. Which means it's time to find out whose predictions were more on the money, and send the victor to the next round, where they face off against a new forecasting phenom. Since our last game, housing and inflation have cooled, but the job market keeps going strong. And the possibility of a recession still looms large. Our forecasters tell us what they see in the economy now, and what they expect in the months ahead.This episode was produced by James Sneed. It was engineered by Katherine Silva.

For the last four decades, technology has been mostly a force for greater inequality and a shrinking middle class. But new empirical evidence suggests that the age of AI could be different. We speak to MIT's David Autor, one of the greatest labor economists in the world, who envisions a future where we use AI to make a wider array of workers much better at a whole range of jobs and help rebuild the middle class.This episode was produced by Dave Blanchard and edited by Molly Messick.

Economists say that inflation is just too much money chasing too few goods.But something else can make inflation stick around.If you think of the 1970s, the last time the U.S. had really high sustained inflation, a big concern was rising wages. Prices for goods and services were high. Workers expected prices to be even higher next year, so they asked for pay raises to keep up. But then companies had to raise their prices more. And then workers asked for raises again. This the so-called wage-price spiral.So when prices started getting high again in 2021, economists and the U.S. Federal Reserve again worried that wage increases would become a big problem. But, it seems like the wage-price spiral hasn't happened. In fact wages, on average, have not kept up with inflation.There are now concerns about a totally different kind of spiral: a profit-price spiral. On today's show, why some economists are looking at inflation in a new light.This episode was produced by Sam Yellowhorse Kesler and engineered by Katherine

(Note: this episode originally ran in 2019.)In the 1800s, catching your train on time was no easy feat. Every town had its own "local time," based on the position of the sun in the sky. There were 23 local times in Indiana. 38 in Michigan. Sometimes the time changed every few minutes. This created tons of confusion, and a few train crashes. But eventually, a high school principal, a scientist, and a railroad bureaucrat did something about it. They introduced time zones in the United States. It took some doing--they had to convince all the major cities to go along with it, get over some objections that the railroads were stepping on "God's time," and figure out how to tell everyone what time it was. But they made it happen, beginning on one day in 1883, and it stuck. It's a story about how railroads created, in all kinds of ways, the world we live in today.This episode was originally produced by Alexi Horowitz-Ghazi and edited by Jacob Goldstein.

Back in 2005, Burt Banks inherited a plot of old family land in Delaware. But when it came time to sell it, he ran into a problem: his neighbor had a goat pen, and about half of it crossed over onto his property. Burt asked the goats' owner to move the pen, but when neighborly persuasion failed to get the job done, he changed his strategy. He sued her. And that is when things got complicated.Protecting private property is one of the fundamental jobs of the American legal system. If you hold a deed saying you own a plot of land, it's your land. End of story. Right?But, as Burt would soon learn, the law can get really complicated when it comes to determining who actually owns something. And when goats are involved ... anything can happen.This episode was produced by Willa Rubin and Dylan Sloan and edited by Molly Messick. It was fact-checked by Sierra Juarez.

When you were little, what did you want to be when you grew up? An astronaut, a doctor or maybe a famous athlete? Today one of the most popular responses to that question is influencer – content creators who grow their following on Tik Tok, Instagram and YouTube and monetize that content to make it their full-time job.In a lot of ways influencing can seem like the dream job - the filters, the followers, the free stuff. But on the internet, rarely is anything as it appears. From hate comments and sneaky contracts to prejudice and discrimination, influencers face a number of hurdles in their chosen careers.This week we're bringing you two stories from our daily show The Indicator on the promise and perils of the multi-billion dollar influencer industry.This episode was produced by Corey Bridges and Janet Lee.

After a successful career in advertising, Erika Williams decided it was time for a change. She went back to school to get an MBA at the University of Chicago, and eventually, in 2012, she got a job at Wells Fargo as a financial advisor. It was the very job she wanted.Erika is Black–and being a Black financial advisor at a big bank is relatively uncommon. Banking was one of the last white collar industries to really hire Black employees. And when Erika gets to her office, she's barely situated before she starts to get a weird feeling. She feels like her coworkers are acting strangely around her."I was just met with a lot of stares. And then the stares just turned to just, I mean, they just pretty much ignored me. And that was my first day, and that was my second day. And it was really every day until I left."She wasn't sure whether to call her experience racism...until she learned that there were other Black employees at other Wells Fargo offices feeling the exact same way.On today's episode, Erika's journey t

Note: This episode originally aired in September, 2014.Zoos follow a fundamental principle: You can't sell or buy the animals. It's unethical and illegal to put a price tag on an elephant's head. But money is really useful — it lets you know who wants something and how much they want it. It lets you get rid of things you don't need and acquire things that you do need. It helps allocate assets where they are most valued. In this case, those assets are alive, and they need a safe home in the right climate.So zoos and aquariums are left asking: What do you do in a world where you can't use money?This episode was originally produced by Jess Jiang.Help support Planet Money and get bonus episodes by subscribing to Planet Money+ in Apple Podcasts or at plus.npr.org/planetmoney.

Imagine if we built cars the same way we build houses. First, a typical buyer would meet with the car designer, and tell them what kind of car they want. Then the designer would draw up plans for the car.The buyer would call different car builders in their town and show them the blueprints. And the builders might say, "Yeah, I can build you that car based on this blueprint. It will cost $1 million and it will be ready in a year and a half."There are lots of reasons why homes are so expensive in the U.S., zoning and land prices among them. But also, the way we build houses is very slow and very inefficient. So, why don't we build homes the way we build so many other things, by mass producing them in a factory?In this episode, the century-old dream of the factory-built house, and the possibility of a prefab future.This episode was produced by Emma Peaslee. Molly Messick edited the show, and it was fact-checked by Sierra Juarez. Brian Jarboe mastered the episode. Jess Jiang is our acting Executive Producer.Help

This past January, researchers uncovered that Black taxpayers are three to five times as likely to be audited as everyone else. One likely reason for this is that the IRS disproportionately audits lower-income earners who claim a tax benefit called the earned income tax credit. And this, says law professor Dorothy Brown, is just one example of the many ways that race is woven through our tax system, its history, and its enforcement.Dorothy discovered the hidden relationship between race and the tax system sort of by accident, when she was helping her parents with their tax return. The amount they paid seemed too high. Eventually, her curiosity about that observation spawned a whole area of study.This episode is a collaboration with NPR's Code Switch podcast. Host Gene Demby spoke to Dorothy Brown about how race and taxes play out in marriage, housing, and student debt.This episode was produced by James Sneed, with help from Olivia Chilkoti.

Right now, the economy is running hot. Inflation is high, and central banks are pushing up interest rates to fight it. But before the pandemic, economies around the world were stuck in a different rut: low inflation, low interest rates, low growth. In 2013, Larry Summers unearthed an old term from the Great Depression to explain why the economy was in this rut: secular stagnation. The theory resonated with Olivier Blanchard, another leading scholar, because he had made similar observations himself. Larry and Olivier would go on to build a case for why secular stagnation was a defining theory of the economy and why government policies needed to respond to it. They helped reshape many people's understanding of the economy, and suggested that this period of slow growth and low interest rates was here to stay for a long time.But today, Larry and Olivier are no longer the duo they used to be. As inflation has spiked worldwide, interest rates have followed suit. Earlier this year, Larry announced that he was no lon
