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? This episode was hosted by Erika Beras and Jeff Guo.

Some of the most influential and beloved novels of the last few years have been about money, finance, and the global economy. Some overtly so, others more subtly. It got to the point where we just had to call up the authors to find out more: What brought them into this world? What did they learn? How were they thinking about economics when they wrote these beautiful books? Today on the show: we get to the bottom of it. We talk to three bestselling contemporary novelists — Min Jin Lee (Pachinko and Free Food for Millionaires), Emily St. John Mandel (Station Eleven, The Glass Hotel and Sea of Tranquility), and Hernan Diaz (Trust, In the Distance) – about how the hidden forces of economics and money have shaped their works. This episode was hosted by Mary Childs and Alexi Horowitz-Ghazi. It was produced by Willa Rubin, edited by Molly Messick, and engineered by Neisha Heinis. Fact-checking by Sierra Juarez.

China's economic growth for the past few decades has been extraordinary. And much of that growth was fueled by real estate – it was like this miraculous economic engine for the country. But recently, that engine seems to have stopped working. And that has raised all kinds of questions not just for China but also for the global economy. Today on the show, we look at what's happening inside China's real estate market. And we try to answer the question: how did we get here?

When best-selling thriller writer Douglas Preston began playing around with OpenAI's new chatbot, ChatGPT, he was, at first, impressed. But then he realized how much in-depth knowledge GPT had of the books he had written. When prompted, it supplied detailed plot summaries and descriptions of even minor characters. He was convinced it could only pull that off if it had read his books. Large language models, the kind of artificial intelligence underlying programs like ChatGPT, do not come into the world fully formed. They first have to be trained on incredibly large amounts of text. Douglas Preston, and 16 other authors, including George R.R. Martin, Jodi Piccoult, and Jonathan Franzen, were convinced that their novels had been used to train GPT without their permission. So, in September, they sued OpenAI for copyright infringement. This sort of thing seems to be happening a lot lately–one giant tech company or another "moves fast and breaks things," exploring the edges of what might or might not be allowed without first asking permission. On today's show, we try to make sense of what OpenAI allegedly did by training its AI on massive amounts of copyrighted material. Was that good? Was it bad? Was it legal?

The world of economics has these two different sides. One one side, there are the economists in their cozy armchairs and dusty libraries, high up in their ivory towers. On the other, there's the messy world we're all living in, where those economics are actually playing out. Sometimes, researchers will write about something that they themselves have never actually experienced. Sure, they've thought about it, theorized, come up with smart analyses...but that's not the same as getting out of that armchair and into the real world. So, in this episode, we play our own version of Never Have I Ever. We dare two researchers to go places and do things they have never done before, in hopes of learning something new about the economic world around us. (Okay, fine, it's maybe more like Truth or Dare...but go with us here.) Today's episode was hosted by Alexi Horowitz-Ghazi and produced by Emma Peaslee with help from Willa Rubin.

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.

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.

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.

Right now, a lot of school districts across the country are making a pretty giant change to the way public education usually works. Facing teacher shortages and struggling to fill vacant spots, they are finding a new recruitment tool: the four-day school week. Those districts are saying to teachers, "You can have three-day weekends all the time, and we won't cut your pay." As of this fall, around 900 school districts – that's about 7% of all districts in the U.S. – now have school weeks that are just four days long. And this isn't the first time a bunch of schools have scaled back to four days, so there is a lot of data to lean on to figure out how well it works. In this episode, teachers love the four-day school week, and it turns out even parents love it, too. But is it good for students?

Union membership in the U.S. has been declining for decades. But, in 2022, support for unions among Americans was the highest it's been in decades. This dissonance is due, in part, to the difficulties of one important phase in the life cycle of a union: setting up a union in the first place. One place where that has been particularly clear is at the Volkswagen plant in Chattanooga, Tennessee. Back in 2008, Volkswagen announced that they would be setting up production in the United States after a 20-year absence. They planned to build a new auto manufacturing plant in Chattanooga. Volkswagen has plants all over the world, all of which have some kind of worker representation, and the company said that it wanted that for Chattanooga too. So, the United Auto Workers, the union that traditionally represents auto workers, thought they would be able to successfully unionize this plant. They were wrong. In this episode, we tell the story of the UAW's 10-year fight to unionize the Chattanooga plant. And, what other unions can learn from how badly that fight went for labor.

When someone says "the economy is doing well"—what does that even mean? Like, for workers, for employers, for the country as a whole? According to what calculation? How do you put a number on it? The world of economics is filled with all sorts of "measuring sticks." GDP. Inflation. Unemployment. Consumer sentiment. Over time, all kinds of government agencies, universities and private companies have come up with different ways to measure facets of the economy. These measures factor into all kinds of huge decisions—things like government policy, business strategies, maybe even your personal career choices or investments. On today's show, we're going to lift the curtain on two of these yardsticks. We are going to meet the people tasked with sticking a number on two huge measures of our economic well being: the official U.S. government inflation report and the monthly unemployment and jobs numbers. Come along and see how the measures get made. This episode was hosted by Darian Woods, Stacey Vanek Smith, and Wailin Wong. It was produced by Julia Ritchey and Jess Kung with help from James Sneed.

Note: There is swearing in this episode. In 2017, The University of Minnesota asked comedian Maria Bamford to give their commencement speech. But the University may not have known what it was in for. In her speech, Bamford told the crowd of graduates how much the university offered to pay her (nothing), her counteroffer ($20,000), and the amount they settled on ($10,000), which (after taxes and fees, etc.) she gave away to students in the audience to pay down their student loans. Maria Bamford is a big believer in full disclosure of her finances, a philosophy she's adopted after decades in a Debtors Anonymous support group. In meetings, she learned important financial tips and tricks to go from thousands of dollars in debt to her current net worth of $3.5 million (a number which, true to her philosophy, she will share with anyone). She spoke with us about her financial issues, how she recovered, and why she believes in total financial transparency, even when it makes her look kinda bad. Disclaimer: Planet Money is not qualified or certified to give financial advice. And Maria is not a spokesperson for Debtors Anonymous in any way.

Prices go up. Occasionally, prices go down. But for 70 years, the price of a bottle of Coca-Cola didn't change. From 1886 until the late 1950s, a bottle of coke cost just a nickel. On today's show, we find out why. The answer includes a half a million vending machines, a 7.5 cent coin, and a company president who just wanted to get a couple of lawyers out of his office. This episode originally ran in 2012. This episode was hosted by David Kestenbaum. Alex Goldmark is Planet Money's executive producer.

In 2007, Uruguay had a massive problem with no obvious fix. The economy of this country of 3.5 million people was growing, but there wasn't enough energy to power all that growth. Ramón Méndez Galain was, at the time, a particle physicist, but he wanted to apply his scientific mind to this issue. He started researching different energy sources and eventually wrote up a plan for how Uruguay's power grid could transition to renewable energy. It would be better for the climate, and, he thought, in the long run it would be the most economical choice Uruguay could make. Méndez Galain shared his plan online and in a series of informal lectures. Then, one day he received a phone call from the office of the president of Uruguay, inviting him to put his plan into action. Countries all over the world have announced lofty goals to reduce the emissions that cause climate change. But Uruguay actually did it. In a typical year, 98% of Uruguay's grid is powered by green energy. How did it get there? It involved a scientist, an innovative approach to infrastructure funding, and a whole lot of wind.

When contract negotiations between Alaska Airlines and their flight attendants' union broke down in 1993, the union had a choice to make. The union — The Association of Flight Attendants-CWA — knew that if they chose to strike, Alaska Airlines could use a plan. While Alaska Airlines technically couldn't fire someone on strike, they could permanently replace the striking flight attendants with new workers. Essentially, if the union went on strike, they could risk thousands of people's jobs. The flight attendants knew they needed a counter-strategy. They went with a strategy they called CHAOS: "Create Havoc Around Our System." The strategy had two phases. Phase one: The union kept Alaska guessing about when, where, and how a strike might happen. They kept everyone, even their own members, in the dark. And in turn, Alaska Airlines had to be prepared for a strike at any place and any time. Phase two was to go on strike in a targeted and strategic way. The havoc that the flight attendants created set off a sort-of labor-dispute arms race and would go on to inspire strikes today. And, it showed how powerful it can be to introduce a little chaos into negotiations.

There seems to be headlines about floods, wildfires, or hurricanes every week. Scientists say this might be the new normal — that climate change is making natural disasters more and more common. Tatyana Deryugina is a leading expert on the economics of natural disasters — how we respond to them, how they affect the economy, and how they change our lives. And back when Tatyana first started researching natural disasters she realized that there's a lot we don't know about their long-term economic consequences. Especially about how individuals and communities recover. Trying to understand those questions of how we respond to natural disasters is a big part of Tatyana's research. And her research has some surprising implications for how we should be responding to natural disasters. This episode was hosted and reported by Jeff Guo.

The Nobel-prize winning economist Simon Kuznets once analyzed the world's economies this way — he said there are four kinds of countries: developed, underdeveloped, Japan... and Argentina. If you want to understand what happens when inflation really goes off the rails, go to Argentina. Annual inflation there, over the past year, was 124 percent. Argentina's currency, the peso, is collapsing, its poverty rate is above 40 percent, and the country may be on the verge of electing a far right Libertarian president who promises to replace the peso with the dollar. Even in a country that is already deeply familiar with economic chaos, this is dramatic. In this episode, we travel to Argentina to try to understand: what is it like to live in an economy that's on the edge? With the help of our tango dancer guide, we meet all kinds of people who are living through record inflation and political upheaval. Because even as Argentina's economy tanks, its annual Mundial de Tango – the biggest tango competition in the world – that show is still on.

When a group of amateur investors rallied around the stock for GameStop back in 2021, the story blew up the internet. News outlets around the world, including us here at Planet Money, rushed in to explain why the stock for this retail video game company was suddenly skyrocketing, at times by as much as 1700% in value, and what that meant for the rest of us. When movie producer Aaron Ryder saw the GameStop story — an army of scrappy underdogs, banding together to strike back against a financial system they felt was rigged against them — he knew it had the makings for a great movie. The only problem: so did a bunch of other movie producers and Hollywood studios. So Aaron found himself in the middle of a fast and furious race to make the first Game Stop movie. On today's show, one producer's quest to claim the hottest ticket in Tinseltown and the whole hidden machinery dedicated to turning a news story into box office gold. You'll never read the word 'based on a true story' the same way again. Today's episode was reported and hosted by Alexi Horowitz-Ghazi.

Erin Plante is a private detective who specializes in chasing down stolen cryptocurrency. In March of 2022, she got the biggest assignment of her career: Hackers had broken into an online game called Axie Infinity and made off with over $600 million worth of digital money. It was the largest crypto heist in history. And now it was Erin's job to find that money and get it back. Erin's investigation would lead her to face off against some of the world's most formidable digital money launderers, whose actions would soon raise alarms at the highest levels of government — even threaten the nuclear security of the entire planet.
