You might expect to find economic concepts in the pages of an economics textbook. But you know where you can really see a lot of economic concepts in action? Buffets.

Here at Planet Money we believe there's a lot of economics going on at the all-you-eat buffet, tucked in between the mountains of brisket and troughs of mashed potatoes. From classic concepts like adverse selection, sunk costs, diminishing marginal returns, to more exotic economic mysteries, like the flat rate pricing bias.

Today on the show, we're headed to the place where the modern buffet may have been born: Las Vegas. Our mission? To feast ourselves on all the economics we can handle at the all-you-can-eat buffet. And along the way, an economist and fellow buffet-lover will teach us his hyper-rational strategy for optimizing his buffet experience.

Today's show was produced by James Sneed and Nick Fountain with help from Emma Peaslee. It was edited by Jess Jiang, engineered by James Willetts, and fact-checked by Sierra Juarez. Alex Goldmark is our executive producer.

Earlier this fall, the Federal Trade Commission filed a high-stakes lawsuit against Amazon.

In that suit, the FTC claims Amazon is a monopoly, and it accuses the company of using anti-competitive tactics to hold onto its market power. It's a big case, with implications for consumers and businesses and digital marketplaces, and for antitrust law itself. That is the highly important but somewhat obscure body of law that deals with competition and big business.

And so, this week on Planet Money, we are doing a deep dive on the history of antitrust. It begins with today's episode, a Planet Money double feature. Two classic episodes that tell the story of how the U.S. government's approach to big business and competition has changed over time.

First, the story of a moment more than 100 years ago, when the government stepped into the free market in a big way to make competition work. It's the story of John D. Rockefeller and Standard Oil, and a muckraking journalist named Ida Tarbell.

Then, we fast forward to a turning point that took antitrust in the other direction. This is the story of a lawyer named Robert Bork, who transformed the way courts would interpret antitrust law.

These episodes were produced by Sally Helm with help from Alexi Horowitz Ghazi. They were edited by Bryant Urdstadt. Alex Goldmark is Planet Money's executive producer.

When Lina Khan was in law school back in 2017, she wrote a law review article called 'Amazon's Antitrust Paradox,' that went kinda viral in policy circles. In it, she argued that antitrust enforcement in the U.S. was behind the times. For decades, regulators had focused narrowly on consumer welfare, and they'd bring companies to court only when they thought consumers were being harmed by things like rising prices. But in the age of digital platforms like Amazon and Facebook, Khan argued in the article, the time had come for a more proactive approach to antitrust.

Just four years later, President Biden appointed Lina Khan to be the Chair of the Federal Trade Commission, one of the main government agencies responsible for enforcing antitrust in America, putting her in the rare position of putting some of her ideas into practice.

Now, two years into the job, Khan has taken some big swings at big tech companies like Meta and Microsoft. But the FTC has also faced a couple of big losses in the courts. On today's show, a conversation with FTC Chair Lina Khan on what it's like to try to turn audacious theory into bureaucratic practice, the FTC's new lawsuit against Amazon, and what it all means for business as usual.

Here at Planet Money, Thanksgiving is not just a time to feast on turkey, stuffing, mashed potatoes, green bean casseroles and pie(s). It's also a time to feast on economics. Today, we host a very Planet Money Thanksgiving feast, and solve a few economic questions along the way.

First: a turkey mystery. Around the holidays, demand for turkey at grocery stores goes up by as much as 750%. And when turkey demand is so high, you might think that the price of turkey would also go up. But data shows, the price of whole turkeys actually falls around the holidays; it goes down by around 20%. So what's going on? The answer has to do what might be special about supply and demand around the holidays.

We also reveal what is counted (and not counted) in the ways we measure the economy.

And we look to economics to help solve the perennial Thanksgiving dilemma: Where should each dinner guest sit? Who should sit next to whom?

In the state of Oregon, there is a glut of grass. A wealth of weed. A crisis of chronic.

And, jokes aside, it's a real problem for people who work in the cannabis industry like Matt Ochoa. Ochoa runs the Jefferson Packing House in Medford, Oregon, which provides marijuana growers with services like drying, trimming and packing their product. He has seen literal tons of usable weed being left in marijuana fields all over the state of Oregon. Because, Ochoa says, there aren't enough buyers.

There are just over four million people in Oregon, and so far this year, farmers have grown 8.8 million pounds of weed. Which means there's nearly a pound of dried, smokable weed for every single person in the state of Oregon. As a result, the sales price for legal marijuana in the last couple of years has plummeted.

Economics has a straightforward solution for Oregon's overabundance problem: trade! But, Oregon's marijuana can only be sold in Oregon. No one in any state can legally sell weed across state lines, because marijuana is still illegal under federal law. On today's episode, how a product that is simultaneously legal and illegal can create some... sticky business problems.

Picture the Pacific Ocean of the 16th century. Spanish Galleons sail the wide open seas, carrying precious cargo like silver, porcelain, and textiles. The waters are dangerous; ship logs show concerns over pirates. But pirates are not to blame for a mysterious event that keeps happening.

For, you see, one in five of the ships leaving from the port of Manila didn't make it to Acapulco. It's a shipwrecking rate much higher than rates for other routes of the time. And the mystery of the serial shipwrecking Spanish ships remains unsolved, until today.

Everyone involved with these Spanish ships were aligned in a goal: Don't wreck the Spanish ships. And yet, wreck they did. Three economists took a look at the incentives for profit and risk at the time, and found the key to unlocking this ancient booty (of knowledge).

On today's episode, we have three big economic ideas for your consideration – ideas that could potentially improve the economy and make us more efficient.

First, what if we ban left turns on roads? Then, what if we gave every new baby ... a trust fund? And lastly, what if we completely got rid of U.S. congressional districts?

That's all on today's episode.

At around 1 a.m. on the morning of November 15, 1994, Captain Prentice "Skip" Strong III woke to a distress call. Skip was the new captain of an oil tanker called the Cherry Valley. He and his crew had been making their way up the coast of Florida that evening when a tropical storm had descended. It had been a rough night of 15 foot waves and 50 mile per hour winds.

The distress call was coming from a tugboat whose engines were failing in the storm. Now adrift, the tugboat was on a dangerous collision course with the shore. The only ship close enough to mount a rescue was the Cherry Valley.

Skip faced a difficult decision. A fully loaded, 688-foot oil tanker is hardly anyone's first choice of a rescue vessel. It is as maneuverable as a school bus on ice. And the Cherry Valley was carrying ten million gallons of heavy fuel oil. A rescue attempt would put them in dangerously shallow water. One wrong move, and they would have an ecological disaster on the order of the Exxon Valdez.

What happened next that night would be dissected and debated for years to come. The actions of Skip and his crew would lead to a surprising discovery, a record-setting lawsuit, and one of the strangest legal battles in maritime history. At the center of it all, an impossible question: How do you put a price tag on doing the right thing?

It's Groundhog Day, and the eyes of the nation have turned to a small town in western Pennsylvania. And, just like last year, all anyone can talk about is Punxsutawney Phil! It is impossible to find a news story that is not about one furry prognosticator.

Well, almost impossible...

Once again, our Planet Money hosts find themselves trapped in the endless Groundhog Day news cycle, and their only way out is to discover an economics story from Groundhog Day itself interesting enough to appease the capricious Groundhog Gods!

So rise and shine campers (and don't forget your booties) as hosts Kenny Malone and Amanda Aronczyk scour the news of February 2nds past, to try to find the perfect story.

There's been a lot of disagreement in Congress and in the country about whether the U.S. should continue to financially support the wars in Ukraine and Gaza.

Some taxpayers don't think the U.S. should give Ukraine any money to fight off Russia's invasion. And some taxpayers have concerns about how they might be funding weapons that have been used to kill civilians in Gaza. And there are questions about how much individual taxpayers contribute to war efforts, generally.

So in this episode, we attempt to do the math: The average taxpayers' contribution to Israel and Ukraine. It's not so simple. But in attempting to do this math, we get this window into the role of our tax dollars on foreign assistance, and how the U.S. sells weapons to other countries.

Last month, Japan's central bank raised interest rates for the first time in 17 years. That is a really big deal, because it means that one of the spookiest stories in modern economics might finally have an ending.

Back in the 1980s, Japan performed something of an economic miracle. It transformed itself into the number two economy in the world. From Walkmans to Toyotas, the U.S. was awash in Japanese imports. And Japanese companies went on a spending spree. Sony bought up Columbia Pictures. Mitsubishi became the new majority owners of Rockefeller Center.

But in the early 1990s, it all came to a sudden halt. Japan went from being one of the fastest growing countries in the world to one of the slowest. And this economic stagnation went on and on and on. For decades.

On this episode, the unnerving story of Japan's Lost Decades: How did one of the most advanced economies in the world just fall down one day — and not be able to get up? Japan's predicament changed our understanding of what can go wrong in a modern economy. And gave us some new tools to try and deal with it.

What's going on with consumers? This is one of the trickiest puzzles of this weird economic moment we're in. We've covered a version of this before under the term "vibecession," but it's safe to say, the struggle is in fact real. It is not just in our heads. Sure, sure, some data is looking great. But not all of it.

What's interesting, is exactly why the bad feels so much worse than the good feels good. Today on the show, we look into a few theories on why feelings are just not matching up with data. We'll break down some numbers and how to think about them. Then we look at grocery prices in particular, and an effort to combat unfair pricing using a mostly forgotten 1930's law. Will it actually help?

By one estimate, 40 percent of American workers get laid off at least once in their careers. And when that happens, companies will often say, "It's not personal. It has nothing to do with you or your performance. We're just changing priorities, making a strategic shift."

It's like the business version of: "It's not you, it's me." And just like a breakup, it feels terrible.

This happened to a man we're calling V, who was working at the same company as his husband when he got laid off. And for V, the experience felt shocking. It left him and his husband with a lot of unresolved questions.

On today's show, the story of that layoff. And we help that couple get some answers by taking their questions to an HR expert who gives the low-down on lay-offs.

This story is adapted from a 3-part series on layoffs produced by Yowei Shaw for her show, Proxy. The layoff series was edited by John DeLore with research and reporting help from Kim Nederveen Pieterse. You can listen to the full layoff series from Proxy wherever you get your podcasts, and you can support the show and find out more by going to patreon.com/proxypodcast. And you can check out her original song "Gold Star" on Spotify and YouTube.

There is a constant arms race between law enforcement and criminals, especially when it comes to technology. For years, law enforcement has been frustrated with encrypted messaging apps, like Signal and Telegram. And law enforcement has been even more frustrated by encrypted phones, specifically designed to thwart authorities from snooping.

But in 2018, in a story that seems like it's straight out of a spy novel, the FBI was approached with an offer: Would they like to get into the encrypted cell phone business? What if they could convince criminals to use their phones to plan and document their crimes — all while the FBI was secretly watching? It could be an unprecedented peek into the criminal underground.

To pull off this massive sting operation, the FBI needed to design a cell phone that criminals wanted to use and adopt. Their mission: to make a tech platform for the criminal underworld. And in many ways, the FBI's journey was filled with all the hallmarks of many Silicon Valley start-ups.

On this show, we talk with journalist Joseph Cox, who wrote a new book about the FBI's cell phone business, called Dark Wire. And we hear from the federal prosecutor who became an unlikely tech company founder.

There's a behind the scenes industry that helps big brands decide questions like: How big should a bag of chips be? What's the right size for a bottle of shampoo? And yes, also: When should a company do a little shrinkflation?

From Cookie Monster to President Biden, everybody is complaining about shrinkflation these days. But when we asked the packaging and pricing experts, they told us that shrinkflation is just one move in a much larger, much weirder 4-D chess game.

The name of that game is "price pack architecture." This is the idea that you shouldn't just sell your product in one or two sizes. You should sell your product in a whole range of different sizes, at a whole range of different price points. Over the past 15 years, price pack architecture has completely changed how products are marketed and sold in the United States.

Today, we are going on a shopping cart ride-along with one of those price pack architects. She's going to pull back the curtain and show us why some products are getting larger while others are getting smaller, and tell us about the adorable little soda can that started it all.

By the end of the episode, you'll never look at a grocery store the same way again.

We wade into the heated debate over immigrants' impact on the labor market. When the number of workers in a city increases, does that take away jobs from the people who already live and work there? Does a surge of immigration hurt their wages?

The debate within the field of economics often centers on Nobel-prize winner David Card's ground-breaking paper, "The Impact of the Mariel Boatlift on the Miami Labor Market." Today on the show: the fight over that paper, and what it tells us about the debate over immigration.

At the core of most of the electronics we use today are some very tiny, very powerful chips. Semiconductor chips. And they are mighty: they help power our phones, laptops, and cars. They enable advances in healthcare, military systems, transportation, and clean energy. And they're also critical for artificial intelligence, providing the hardware needed to train complex machine learning.

On today's episode, we're bringing you two stories from our daily show The Indicator, diving into the two most important semiconductor chip companies, which have transformed the industry over the past 40 years.

First, we trace NVIDIA's journey from making niche graphics cards for gaming to making the most advanced chips in the world — and briefly becoming the world's biggest company. Next, we see how the Taiwan Semiconductor Manufacturing Company's decision to manufacture chips for its competition instead of itself flipped the entire industry on its head, and moved the vast majority of the world's advanced chip production to Taiwan.

Planet Money Summer School is back for eight weeks. Join as we travel back in time to find the origins of our economic way of life. Today we ask surprisingly hard question: What is money? And where did it come from? We travel to a remote island in the Pacific Ocean for the answer. Then we'll visit France in the year 1714, where a man on the lam tries to revolutionize the country's entire monetary system, and comes impressively close to the modern economy we have today, before it all falls apart. Check out our Summer School video cheat sheet on the origins of money at the Planet Money TikTok.

Who has the power? Workers or bosses? It changes through the ages, though it's usually the bosses. Today, we look at two key moments when the power of labor shifted, for better and worse, and we ask why then? What does history have to say about labor power right now?

We travel to Sicily, Italy in the year 1347, where the bubonic plague is about to strike. The horror known as the Black Death will remake European society in countless ways, but we'll focus on one silver lining: how economic conditions shifted for workers.

Then we head about 500 years into the future, to an English factory at the dawn of the Industrial Revolution, where textile workers take up arms against the machines taking their jobs and show how rapidly labor supply and demand can change. This is the famed tale of the Luddites, now a byword for knee jerk anti-technology, but the true story has nuance and a desperate but rational violent rebellion.

Once upon a time, every business was a small business. It was run by the owner, maybe the spouse and the kids. Maybe they borrowed money from friends and relatives, but there was only so big it could get. Then came what can only be described as the big bang of economics. Over the span of a few decades, people figured out a way for businesses to sell ownership shares – otherwise known as stocks – and let people trade those shares. There was suddenly money to buy machines and expand.

Today, we head to the Netherlands around the year 1600. First, we'll visit the bridge in Amsterdam where some of the first stock trading took place. Then we track down the Dutch water company that's the source of the oldest "living" bond. It's the origin of stocks and bonds and the stock market and it leads directly to many of the financial innovations that we still have today.

Planet Money Summer School has arrived at the birth of the United States and the chance to set up a whole new economy from scratch. Should there be a centralized bank? Should there be a single currency? We'll travel to two moments in the country's early history when the founders said "nope" to these questions and see what happened.

First we'll witness one of the great economic battles in U.S. history – the president of the United States versus the president of the Bank of the United States – and see how the outcome ushered in an age of financial panics. Then we'll drop in on a time before the U.S. dollar existed as we know it, when you could buy things using one of about 8,000 forms of money circulating in the country. We watch as the Civil War leads to the first standard currency. Along the way, we'll learn why the cycle of economic booms and busts persists to today despite efforts to centralize America's economy throughout history.

For some sports, picking the winner is simple: It's the athlete who crosses the finish line first, or the side that scores the most goals. But for the new Olympic sport of breaking (if you want to be cool, don't call it breakdancing), the criteria aren't quite that straightforward. How do you judge an event whose core values are dopeness, freshness, and breaking the rules?

That was the challenge for Storm and Renegade, two legendary b-boys who set out to create a fair and objective scoring system for a dance they say is more of an art than a sport. Over the years, their journey to define the soul of breaking led them to meetings with Olympics bigwigs, debates over the science of dopeness, and a battle with a question many sports — from figure skating to gymnastics — have tried to answer: Can art and sport coexist?

In the middle of the twentieth century, China and its neighbors in East Asia were poor, mostly rural economies. China had been wrecked by a brutal civil war. Taiwan became the home of people fleeing from that conflict. Japan and Korea were rebuilding after their own wars. And then in the later half of the twentieth century, they started their comeback. The governments made some explicit choices that unleashed the power of individual incentives and free market forces and lifted millions of people out of poverty. We focus specifically on China and Taiwan during this time, when they showed a burst of economic progress rarely seen on this globe. Why then? Why there? Can other nations copy that? We'll try to find out.

You might have seen ads for online banking services that seem to offer a lot of great stuff — accounts you can open in minutes and without a minimum balance or monthly fees. The ads seem to say: "These aren't your parents' boring old banks." But the truth is: Even though they might resemble banks, they aren't.

These "bank-like" companies are a type of "fintech" or financial technology company. And this is a story about the potential risks of putting your money into these apps.

Banks go through a whole regulatory gauntlet in order to exist. But, in the past several years, there has been a rise in fintechs that skirt regulations. And many of these pose a real threat to even the most savvy of depositors.

When a little known tech company filed for bankruptcy a few months ago, thousands of people couldn't access the millions of dollars they saved. On today's show, we meet some of the people affected and learn what the fintech industry reveals about banking regulation.

Today's show was hosted by Erika Beras and Sally Helm. It was produced by Sam Yellowhorse Kesler and Sofia Shchukina with help from James Sneed.

When we last left the United States of America in our economic telling of history, it was the early 1900s and the country's leaders were starting to feel like they had the economic situation all figured out. Flash forward a decade or so, and the financial picture was still looking pretty good as America emerged from the first World War.

But then, everything came crashing down with the stock market collapse of 1929. Businesses closed, banks collapsed, one in four people was unemployed, families couldn't make rent, the economy was broken. And this was happening all over the world. Today we'll look at how leaders around the globe intervened to turn the international economy around, and in the process, how the Great Depression rapidly transformed the relationship between government and business forever.

We are assembled here on the lawn of Planet Money University for the greatest graduation in history – because it features the greatest economic minds in history. We'll hear from Adam Smith, Karl Marx, John Maynard Keynes, and some surprising guests as they teach us a little bit more economics, and offer a lot of life advice.

But first, we have to wrap up our (somewhat) complete economic history of the world. We'll catch up on the last fifty years or so of human achievement and ask ourselves, has economics made life better for us all?

People often say that money can't buy you happiness. Sometimes, if you ask them to tell you more about it, they'll mention a famous 2010 study by Nobel Prize winners Daniel Kahneman and Angus Deaton. That study found that higher household income correlates with greater emotional well-being, but only up to around $75,000 a year. After that, more money didn't seem to matter.

This was a famous study by two famous academics. The result stood for over a decade. And it feels good, right? Maybe the rich aren't so much happier than anyone else. But researchers have recently done a complete 180 on this idea. In 2021, psychologist Matt Killingsworth found nearly the opposite: That more money does correlate with more happiness. And that the relationship continues well beyond $75,000 per year.

Today on the show: Does more money mean fewer problems? Two researchers with totally different takes come together to hammer out a better understanding of the relationship between money and happiness.

Recently, the state of Washington embarked on an ambitious new plan to combat climate change. Taking a page from economics textbooks, the state instituted a statewide "cap and trade" system for carbon emissions. The state establishes a cap on the total amount of carbon pollution it is willing to allow each year, and then gives away or auctions off carbon emission permits that add up to that total. Companies can then trade those permits on the open market.

Economists love cap and trade plans because they establish a limit on carbon emissions while letting the market find the most efficient way for decarbonization to occur. But cap and trade has had a hard time catching on, especially in the U.S.

The stakes are high for Washington's new plan. If it succeeds, it could convince other states to implement their own versions, but if it fails, it might serve as a cautionary tale. On today's show, we take a look at how Washington's grand experiment with cap and trade is faring.

Even in our modern world with planes and jets and drones, the vast majority of goods are moved around the planet in cargo ships. Which means our ports are the backbone of our global economy. The longshoremans' strike closed the eastern ports for only three days, but those three days raised a lot of questions.

Like - why is a discount furniture store the fourth largest importer on the East Coast? How come so many bananas come through Wilmington, Delaware? Why do we need live frogs delivered into the US six times a month? And... how do we even keep track of all of these imports? On today's episode, we get into #PortFacts!

(For our story on this year's Nobel in Economics, check out our daily show, The Indicator!)

Let's face it. Economics is filled with terms that don't always make sense to the average person. Terms that sometimes mean what you think they mean, but sometimes not at all. Not even close.

We surveyed 188 economists. And we asked them: What are the most misunderstood terms in the field of economics?

On today's show, their answers! Hear stories about near recessions, a problem with insurance, econ at your local movie theater, and... an economics term that will make undergrads blush. Strap in, and bring your popcorn!

This episode was hosted by Amanda Aronczyk and Alexi Horowitz-Ghazi. It was produced by Sam Yellowhorse Kesler with help from Sean Saldana. It was edited by Jess Jiang, engineered by Valentina Rodríguez Sánchez and fact-checked by Sierra Juarez. Alex Goldmark is our executive producer.

On today's show, we have two stories from The Indicator, Planet Money's daily podcast. They just launched Love Week, a weeklong series exploring the business and economic side of romance.

First, hosts Wailin Wong and Adrian Ma fire up the gas logs and pour a mug of cocoa to discuss the made-for-TV rom-com machine, and how television executives learned to mass produce seasonal romance.

Then, Wailin and host Darian Woods discuss another romance medium: the romance novel. Once relegated to supermarket aisles, these books are now mainstream. And authors, an often-maligned group within publishing, have found greater commercial success than many writers in other genres. We find out how romance novelists rode the e-book wave and networked with each other to achieve their happily-for-now status in the industry.

This episode is hosted by Erika Beras, Wailin Wong, Adrian Ma, and Darian Woods. These episodes of The Indicator were originally produced by Julia Ritchey and engineered by Kwesi Lee. They were fact-checked by Sierra Juarez. Kate Concannon is The Indicator's Editor.

Ray and Becky Queen live in rural Oklahoma with their kids (and chickens). The Queens were able to buy that home with a VA loan because of Ray's service in the Army. During COVID, the Queens – like millions of other Americans – needed help from emergency forbearance. They were told they could pause home payments for up to a year and then pick up again making affordable mortgage payments with no problems.

That's what happened for most American homeowners who took forbearance. But not for tens of thousands of military veterans like Ray Queen.

On today's show, we follow two reporters' journey to figure out what went wrong with the VA's loan forbearance program. How did something meant to help vets keep their houses during COVID end up stranding tens of thousands of them on the brink of foreclosure? And, once the error was spotted, did the government do enough to make things right?

Back in the 90s, the federal government ran a bold experiment, giving people vouchers to move out of high-poverty neighborhoods into low-poverty ones. They wanted to test if housing policy could be hope – whether an address change alone could improve jobs, earnings and education.

The answer to that seems obvious. But it did not at all turn out as they expected.

Years later, when new researchers went back to the data on this experiment, they stumbled on something big. Something that is changing housing policy across the country today.

Today's episode was originally hosted by Karen Duffin, produced by Aviva DeKornfeld, and edited by Bryant Urstadt. The update was hosted by Amanda Aronczyk, produced by Sean Saldana and fact checked by Sierra Juarez. Our supervising executive producer is Alex Goldmark.

This is the story behind one of the most valuable — and perhaps, most improbable — technologies humanity has ever created. It's a breakthrough called extreme ultraviolet lithography, and it's how the most advanced microchips in the world are made. The kind of chips powering the latest AI models. The kind of chips that the U.S. is desperately trying to keep out of the hands of China.

For years, few thought this technology was even possible. It still sounds like science fiction: A laser strong enough to blast holes in a bank vault hits a droplet of molten tin. The droplet explodes into a burst of extreme ultraviolet light. That precious light is funneled onto a wafer of silicon, where it etches circuits as fine as a strand of DNA. Only one company in the world that can make these advanced microchip etching machines: a Dutch firm called ASML.

Today on the show, how this breakthrough in advanced chipmaking happened — and how it almost didn't. How the long-shot idea was incubated in U.S. nuclear weapons laboratories and nurtured by U.S. tech giants. And, why a Dutch company now controls it.

This episode was hosted by Jeff Guo and Sally Helm. It was produced by Willa Rubin and edited by Jess Jiang. It was fact-checked by Dania Suleman, and engineered by Patrick Murray. Alex Goldmark is Planet Money's executive producer.
