All you can eat economics

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.

Cutting school... by 20%

1 Recommendations

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?

Antitrust in America (classic)

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.
