How to win a penalty shootout (with game theory)
⏱ 17 min listen · ~2 min read
🎙 The Soccernomics team
The rare economics episode with a genuine thriller in the middle — and the rock-paper-scissors detour will change how you play it.
Key takeaways
- 01Lionel Messi is the top World Cup scorer of all time and only an average penalty taker, because a penalty is a guessing game rather than a test of finishing.
- 02Stefan Szymanski's rule for penalty takers: aim at your weaker side part of the time, at random, because a predictable shooter is a stopped shooter.
- 03Goalkeepers pick a side before the ball is struck, running the same calculation in mirror image — the symmetry that lets Soccernomics treat a penalty as a game.
- 04Ignacio Palacios-Huerta built the world's best penalty database from videos his wife and mother mailed from Spain, out-scouting clubs that tracked nothing.

Big Lettuce meets Small Intestine
⏱ 25 min listen · ~3 min read
🎙 Jim Gorney
It turns a gross news story into a clear explanation of how salad became an industrial product and why the FDA still can't reliably keep parasites out of it.
Key takeaways
- 01The cyclospora outbreak has infected more than 1,600 people, traced by the FDA to shredded lettuce from Taylor Farms and a recall across 27 states.
- 02Breathable film made bagged salad possible in the 1990s, but mixing many farms' produce into one bag turns a single contaminated field into a national outbreak.
- 03Salad-factory capital costs concentrated the market into about three processors, with Taylor Farms the biggest, supplying McDonald's, Costco and Whole Foods.
- 04Until the 2010 food-safety law the FDA had no authority over farms at all, and routine farm inspections did not begin until 2019.

Seven allegedly fake Chanel bags vs The RealReal
⏱ 25 min listen · ~2 min read
🎙 Graham Wetzbarger
It's the clearest explanation you'll hear of who actually gets to declare a $6,600 bag real — told through the lawsuit that could remake the entire resale market.
Key takeaways
- 01A mini red Chanel flap bag is $6,600 in a Soho window and $1,325 on The RealReal, and that gap is the whole secondhand luxury market.
- 02The RealReal authenticates blind because Chanel keeps its serial-number database private, leaving materials, construction, hardware and brand identifiers.
- 03Graham Wetzbarger's tell is execution: counterfeit serial tabs use wrong fonts, wrong placement and craft-store glitter, while genuine ones are always perfect.
- 04Chanel's 2018 suit rests on seven allegedly fake bags but argues only Chanel can know what is genuine Chanel, which attacks the whole resale model.

Can World Cup mania grow MLS in the U.S.?
⏱ 26 min listen · ~3 min read
🎙 Becky Sullivan
It catches a marketing natural experiment mid-run, with league and club executives explaining their actual budgets and bets before anyone knows which one worked.
Key takeaways
- 01The 1994 World Cup was awarded to the U.S. on the condition that it launch a top-tier men's professional league, which became MLS in 1996.
- 02MLS already has 30 teams and every game televised, so the obvious growth moves are used up and each club is inventing its own conversion play.
- 03The Chicago Fire budgeted $2-3 million, rejected flying 25 CEOs to the final, and rented a city block for one of the biggest watch parties outside a host city.
- 04New England's Brian Bilello lobbied for years and landed seven matches including a quarterfinal, betting that a World Cup crowd converts into MLS season tickets.

Can the Trump administration make college cheaper?
⏱ 28 min listen · ~3 min read
🎙 Corey Turner
It compresses twenty years of actual research on a policy that started hitting grad students the day it aired, and is honest about where the evidence cuts both ways.
Key takeaways
- 01From July 1, 2026 federal loans for most graduate programs are capped near $21,000 a year, ending the unlimited Grad PLUS borrowing that began in 2006.
- 02Undergraduate net price — what families actually pay after aid — has been flat for about 10 years, while graduate tuition is where costs ballooned.
- 03Education Secretary Linda McMahon's premise is the Bennett hypothesis: federal aid lets colleges raise tuition, so lending less should force prices down.
- 04Jeff Denning's study of Texas graduate programs found prices rose 64 cents for every extra dollar students could borrow, the strongest evidence for that.

Our mission: Find the world’s best economic ideas (Summer School World Tour)
⏱ 37 min listen · ~3 min read
🎙 Justin Wolfers
Two well-told case studies — water traded like a stock and the origin story of the 2% inflation target — with Wolfers supplying the actual economics between them, including who wins, who loses, and why.
Key takeaways
- 01Anyone in Australia can buy and sell water on an exchange from a phone, unlike US water rights, which are generally tied to the land they sit under.
- 02Neil Hughes's modelling puts the southern basin's gains from water trading at about 12% of the value of water rights, roughly $117 million a year.
- 03Water went from $100 to $1,000 a megalitre in 2019 as investors bought allocations instantly, and farmer Carly Marriott drove five hours to protest in Canberra.
- 04The Australian review answered the backlash with three rules: regulate water like finance, write rules for a changing climate, and share forecasts with farmers.
