Ride along as our game-making partners at Exploding Kittens help us turn our (sometimes wild) economics game ideas into the next blockbuster game. It’s a behind the scenes look at how to design a game from scratch — a game that is somehow filled with economics, impossible to put down, but does not feel like you’re cramming for school. Which is… harder than we thought. After months of trying to find the perfect balance of ideas and entertainment, the Planet Money game is ready for our next phase. And that’s where you come in, listeners! We need you to playtest the Planet Money game to help us perfect it.

We want to make a board game. It must, of course, teach the world about economics. It must be fun. It’d be nice if it sold lots of copies! How hard could that be!? (Monopoly and Catan are hugely popular and basically little economy simulators, after all.) Well, turns out, it’s quite hard! We’re in a golden age of tabletop games. Thirty years ago there were around 800 new games each year. Now it is more like 5,000. Just a handful of those get to be hits.  In the first episode of our new series, Planet Money sets forth on an epic quest to beat the odds.  Subscribe to Planet Money+ [https://n.pr/3HlREPz] Listen free: Apple Podcasts [http://n.pr/PM-digital], Spotify [https://n.pr/3gTkQlR], the NPR app [https://n.pr/3Bkb17W] or anywhere you get podcasts.

The next time you open your fridge, take a second to behold the miracles inside of it: Raspberries from California, butter from New Zealand, steak from Nebraska. None of that would have been remotely possible before the creation of the cold chain.  The cold chain is the name for the end-to-end refrigeration of our food from farm to truck to warehouse to grocery store and ultimately to our fridges at home. And it’s one of the great achievements of the modern world.  On today’s show, Nicola Twilley, food journalist and author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, tells us the story of how our world got cold, and what that’s meant for the economy.   We’ll hear about two pioneers of cold: The cheapskate meat baron Gustavus Swift, and the train-hopping chemist Polly Pennington. And we’ll take a look at whether all this refrigeration might have created some new problems.  Subscribe to Planet Money+ [https://n.pr/3HlREPz] Listen free: Apple Podcasts [http://n.pr/PM-digital], Spotify [https://n.pr/3gTkQlR], the NPR app [https://n.pr/3Bkb17W] or anywhere you get podcasts.

On Wall Street, fortunes are often won and lost with the tiniest advantages. And for the past few years, one trading firm has stood out from the rest for both huge profits and careful secrecy — Jane Street Group. But last year, one of Jane Street’s biggest and most lucrative trading strategies was unexpectedly revealed in a Manhattan courtroom. The news ricocheted around the world. It drew the attention of competitors and regulatory agencies, destabilized billions of dollars worth of trades, and called into question some of the most fundamental strategies in global finance.  Some Planet Money episodes about finance: - The rise and fall of Long Term Capital Management [https://www.npr.org/2025/02/21/1232862544/long-term-capital-management-ltcm] - How George Soros forced the UK to devalue the pound [https://www.npr.org/2024/12/04/1216966368/george-soros-british-pound-bessent-johnson-druckenmiller] Further reading:  - Jane Street Group, LLC v.

Israel has been blocking the flow of physical money into Gaza since the start of the war. So whatever paper cash was in Gaza before the war, that’s all that’s been circulating. It's falling apart from overuse.  Two best friends, one in Gaza and one in Belgium, are now trying to get money in. But how do you get money into a bank account in Gaza? And how do you get that money out, in Gaza, when there are no functioning banks or ATMs? And almost no electricity. And spotty internet. And what is there to buy? How does money even work in Gaza right now?  Subscribe to Planet Money+ [https://n.pr/3HlREPz] Listen free: Apple Podcasts [http://n.pr/PM-digital], Spotify [https://n.pr/3gTkQlR], the NPR app [https://n.pr/3Bkb17W] or anywhere you get podcasts.
