Let’s head to a small town in Kenya that’s become globally famous for helping economists answer some of the biggest questions facing humanity.In Kenya and Nigeria, economics isn’t just theory, it’s real life. We’ll look at some radical experiments that turned out to be enormously successful.What are the building blocks of health, education and prosperity for all? How does a nation grow rich? What is the most effective way to spend a dollar to fight poverty? We find answers in a town that became the laboratory for new concepts in economic research that netted some researchers the most prestigious prize in economics.Featured Episodes:How randomized trials and the town of Busia, Kenya changed economics (2023)Nigeria, You Win!

As the World Cup comes to a close, so does a massive real-time experiment happening just around the edges. Major League Soccer – the top men’s professional soccer league in the U.S. and Canada – has been scrambling to take advantage of this once-in-a-generation opportunity when average American sports fans suddenly cared a lot about soccer.In between World Cup matches, NPR Sports Correspondent Becky Sullivan has been following Major League Soccer executives as they try to figure out how best to get a foot in the door with sports fans in the U.S.In this episode, we tag along to see if U.S. and Canadian professional soccer can harness 2026 for the mythical World Cup bump in soccer interest. What strategies are teams using? And does it stand a chance to work?Support:Planet Money+Read:Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThis episode of Planet Money was ho

China’s turbocharged growth may have made it rich, but now it has to deal with rich country problems. High-speed trains that connect every town. Gleaming new bridges and skyscrapers. An apartment (or two) for every family. No country on Earth has seen the kind of economic growth that China has over the last 50 years. China has become the factory to the world, a grand experiment in central government planning mixed with personal ambition. It was all enabled by what our guide for today calls, an engineering state, a central planning mindset where leaders believe they can engineer their way out of economic problems. And problems are mounting. Today on the show, the perils of prosperity and the despair of success as China deals with overbuilding. We’ll travel back to China’s free-wheeling boom-era of the early 2000s and hang out with a property developer who amassed his wealth at the center of the action – private jet rides, thousand-dollar fish soup, casual bribes. Then, as the economy slows, we ask what can we

Once upon a time, if you wanted to buy a luxury brand item secondhand (say, a Chanel handbag) you had to have an in. There was no easy way to find one. But over the past decade, the market for secondhand luxury goods has exploded. There are now many online resellers where you can shop for used and discounted luxury items. One big problem — how can you be sure if it’s real and authentic?Some online resellers claim to have solved this problem. They say they’ve developed a process of authentication, and so buyers can trust that the bag is really Gucci or Cartier or Hermès or whatever. But according to some luxury brands, authenticity is something that is often imitated but never replicated.In today’s episode of Planet Money, the fight between Chanel and The RealReal. And how luxury brands are reacting to the enormous and growing secondhand market for luxury goods.Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your LifeOur weekly longform Planet Money newsletterOur we

Come along as we travel the world in search of the best economic ideas to bring home!From the beaches of Barbuda to the fjords of Norway, there's money (and money problems) everywhere. For this summer travel season, Planet Money Summer School will take you on a world tour for your ears. Pack that sense of wonder and nose for adventure, this is our semester abroad. We’re going to explore exotic locales and discover cultural norms, but we’re also going to buckle down and learn the biggest economic lessons around the world from our guides.We start as far away as you can get from Planet Money headquarters, New Zealand and Australia. We’ll visit a sheep farm to observe an innovative but controversial market for the most important substance on earth, and we’ll ask when do speculators help and when do they hurt the rest of us? Then, we’ll get to know the economist – and jazz musician – who changed how the entire world fights inflation when he released a secret number to tame the dreaded wild beast. How did that work

Lionel Messi is arguably the greatest soccer scorer of all time. But when it comes to penalty kicks, Messi is merely average. Why? Maybe the answer involves game theory.According to game theory, there’s an optimal strategy for taking penalty kicks. This strategy involves an idea that was once somewhat controversial in economics — that is, until economists started studying soccer players in real life. On today's show, we kick it over to the hosts of the Soccernomics podcast to explain how game theory has changed soccer, and how soccer has changed game theory. Watch the penalty shootout between Manchester United and Chelsea in the Champions League final in 2008. Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebook This episode of Planet Money was produced by Emma Peaslee with help from James Sneed.

Will limiting how much students can borrow force schools to lower their prices? The Department of Education thinks so. It has a new plan to bring down tuition costs. Starting today, July 1st, it’s going to cap how much it’s willing to loan to graduate students. You read that right. To reduce the burden of school…the plan is to give students less money to pay for school. This plan is, in part, based on an idea that’s been floating around higher education circles for decades: The Bennett Hypothesis, which claims there’s a direct relationship between student borrowing and tuition prices. And therefore, if the Department of Education — the biggest student loan provider in the country — limits how much students can take out, then schools will have no choice but to charge students less. This hypothesis was floated roughly 40 years ago...without evidence. But now, as the Trump administration rolls out their Bennettian plan, we have decades of data to see how true this hypothesis is.Today on the show: NPR Education C

In the early 90’s, a company called General Magic began working on a portable device that would allow people to check email, make phone calls, even play games. It was basically a smartphone. But it never caught on.On today’s show, a theory about why this device failed. General Magic had generous investors, world-class talent and creative freedom.

Prediction markets aren’t new. Election betting was common until the 1940s, then mysteriously faded away.There was an entire political era when party bosses were expected to conspicuously gamble on their candidates (even if they secretly hedged).And in the 1980s, a few economists designed an election market that beat out election polling 74 percent of the time.Today, we’re running an excerpt from our friends at Throughline, NPR’s excellent history podcast.

Maybe the real monster in the Alien franchise isn’t actually the killer alien. Because behind the acid blood and jump scares is an even more insidious horror: a single employer with unchecked power. That employer is named Weyland-Yutani, a mega-corporation that dominates workers across the galaxy.Weyland-Yutani is a sort of extreme example of what economists call a monopsony — when one employer dominates a labor market and gains power to underpay and mistreat workers. Sure, it’s science fiction. But a growing number of economists argue that monopsony power is a much bigger deal in the real world than previously thought.We watch scenes from the movie Alien with labor economist Arin Dube, whose new book, The Wage Standard, shines a spotlight on the problem of monopsony power in the modern economy. We ask Arin what policy ideas he has that would have maybe prevented the worker tragedy seen in Alien. And we use his answer to try and rewrite the movie (spoiler: the movie becomes much shorter and less exciting).Plu

The cyber weapon that might have prevented nuclear war.The U.S. and Israel have long been in conflict with Iran over their nuclear development program. Some of that conflict has been out in the open, with bombs and blockades, but some of it has been invisible. Recently some security researchers discovered a cyberweapon likely tied to that invisible conflict. It looks like it was designed to hide on nuclear scientists computers, then throw off their calculations--just as they got close to achieving their goals.Sounds like something out of science fiction. But it was created 20 years ago. On today’s show: a whodunit about hackers, ‘Cyber Paleontologists’, spy-vs-spy protocols, cryptic intelligence leaks, nuclear physics, high-precision math, and epistemological warfare.Pictured: Juan Andres Guerrero Saade (JAGS) and his ‘Fast16 - NOTHING TO SEE HERE, CARRY ON’ tattoo. Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newslette

Can the government stop you from cutting down your own tree? In many towns and cities these days, removing a tree now requires a permit. You might have to pay a fee, or promise to plant replacement trees. But sometimes, the city won't let you cut down the tree at all, even a tree in your own backyard.That's because trees are important for air quality, for flood control, and for public health. They help keep neighborhoods cool on hot days. But some think that tree protection laws have gone too far — that they might even be unconstitutional.On today's episode, it's the latest showdown between property rights and local zoning laws. Typically, towns and cities enjoy a lot of power when it comes to zoning and permits. They can ban certain types of buildings. They can make you paint your house a certain color. But can they make it illegal to cut down a tree? And what does it mean to "own" a piece of property anyway?Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Lif

One specific type of affordable housing used to be popular in American cities, kept rents low, then nearly vanished. Is it time to reconsider boarding houses and single room occupancy units? If they lowered rents in cities, why did they go away? We have the history.Then, let’s talk about corporate landlords. They’re blamed for driving up rents. Studies show they do the opposite. When corporate landlords come to town, they do buy up homes, which can raise the price to buy, but at the same time lower rents. We’ll parse the impact as we consider a Trump administration plan to restrict corporate home ownership.Related episodes:Is the YIMBY movement doomed? How to fix a housing shortage How to build abundantlyCan Trump make buying a home more affordable?Support:NPR+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThe original episodes of the Indicator were hosted

Have you ever walked around a street, mall, or airport and noticed two or three of the same franchise restaurant within walking distance? Why might one Starbucks or McDonald’s or Wetzel’s Pretzels sometimes be built so close to another? Are they friends or competitors? And how can that possibly be profitable?Today’s show is one such example. Our pals at Hyperfixed got a knotty question we just had to help them untangle: Why are there so many Wetzel’s Pretzels so close to one another at the Atlantic Avenue-Barclays Center Station?To find out, Alexi Horowitz-Ghazi followed the dough all the way to the top.

99% of chemicals in our food right now were added without FDA approval. Many were added in secret, through a sneaky loophole built into the 1958 Food Additives Amendment.It was supposed to require FDA approval for new additives. But food companies and chemical makers found a workaround. And the FDA formally okayed the loophole in the 90s — in the process bringing attention to a loophole to the loophole.The FDA has essentially admitted it doesn’t have the capacity to verify the safety of new food chemicals. So they leave it up to food companies and chemical makers to declare their brand new chemicals are safe. These chemicals are used in everything from chocolate and smoked fish, to tea bags, protein drinks, popcorn, and seeds.So, how’d the loophole get there, and what does it tell us about the priority the U.S. places on safety versus speed and innovation? And, how much can one lawyer do about it?Live show tour and book info. / Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or any

Tax avoidance -- that is, legally reducing your tax bill -- is as American as apple pie. But the line between tax avoidance and tax evasion is often a grey one. On today’s show, a collaboration with Tax Notes, we listen in on the secret tapes that show how the wealthiest Americans avoid taxes. We trace the lifecycle of a tax loophole: how it was born (in Malta), how it grew, how the Feds cracked down, and how the industry came to its rescue -- with the help of one high-ranking Trump administration official.  Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThis episode was produced by Luis Gallo and Emma Peaslee and edited by Marianne McCune.

How does a poor country become a rich country? There's a simple blueprint — or at least, that's what many economists used to believe. But over the years, a lot of rapidly developing economies have stalled out. These countries aren't poor anymore, but they're not rich either. They're stuck in the middle. The World Bank calls this problem the "middle income trap."And if there's a poster child for the middle income trap, many would point to Brazil. For a time, Brazil had one of the fastest growing economies in the world. On today's show, we head to Brazil to understand why the old blueprint for economic development might not work so well anymore.The story starts in the Amazon rainforest.
