Our mission: Find the world’s best economic ideas (Summer School World Tour)

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? Spoiler: it was the great leap forward in economic mind tricks.

How to win a penalty shootout (with game theory)

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 [https://linktr.ee/soccernomicspod] 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 [https://www.youtube.com/watch?v=z-QliFMvpqI].  Support: Planet Money+ [https://n.pr/3HlREPz] Read:  Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life [https://lnk.to/i3AukBdD]  Our weekly longform Planet Money newsletter [https://n.pr/3zrFvUB] Our weekly Indicator round-up newsletter [https://www.npr.org/newsletter/indicator] Follow:  Instagram [https://n.pr/3FqLuws] TikTok [https://n.pr/3sGZdrq] YouTube [https://lnk.to/iCVDaW3C] Facebook [https://n.pr/3h92GwS] This episode of Planet Money was produced by Emma Peaslee with help from James Sneed.

Can the Trump administration make college cheaper?

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 Correspondent Cory Turner explains this theory, and what the new plan influenced by it will mean for borrowers this fall.

We almost had a smartphone in the 90s. Why did it fail?

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. But is it possible what they needed was constraints? Further reading and viewing: David Epstein’s book is Inside the Box: How Constraints Make Us Better [https://davidepstein.com/inside-the-box/].

Before Kalshi and Polymarket there was the Iowa Electronic Markets

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. Subscribe right now if you don’t already [https://www.npr.org/podcasts/510333/throughline]. And, listen to their extended version of the episode [https://www.npr.org/2026/05/21/nx-s1-5828906/prediction-markets-are-making-a-150-year-comeback] to hear about the early markets for betting on terrorism and military uses of prediction markets.
