→ WHAT IT COVERS Planet Money's Summer School examines two African economic experiments: Nigeria's You Win competition, which distributed $60 million in cash grants to small businesses via randomized selection, generating 7,000 jobs at $8,500 per job, and Kenya's Busia town, where randomized controlled trials reshaped global development economics and earned researchers a Nobel Prize.

Key takeaways from recent episodes
Piles of cash and a town of solutions in Kenya, Nigeria (Summer School)
- ✓**Cash grants over loans:** Nigeria's You Win program gave selected entrepreneurs up to $65,000 in non-repayable grants — roughly 10 times annual income — rather than loans. The $60 million program created 7,000 durable jobs at $8,500 per job, a cost-per-job ratio that outperformed most conventional development interventions studied by World Bank researchers.
- ✓**Randomized selection reduces bias:** You Win addressed corruption risk by removing applicants' names from submissions, using judges outside Nigeria, and selecting many winners randomly after eliminating clearly weak plans. This design also enabled rigorous impact measurement, since randomly chosen winners formed a natural control group comparable to non-winners for statistical evaluation.
Big Lettuce meets Small Intestine
- ✓**Supply chain amplification risk:** When vegetables from multiple farms are commingled at large processing facilities, a single contamination event multiplies across millions of servings nationwide. Taylor Farms alone supplies Taco Bell, McDonald's, Costco, Whole Foods, Aldi, and Safeway — meaning one compromised source reaches virtually every major retailer simultaneously.
- ✓**Bagged salad economics created oligopoly:** The 1980s–90s breathable film technology that keeps chopped lettuce fresh transformed lettuce from a low-margin commodity into a high-margin manufactured product. The capital requirements were so steep that today only three processors dominate the entire US fresh-cut vegetable market, with Taylor Farms holding the top position since 1995.
New NPR Series: "We Keep Us Safe" from the Embedded podcast
- ✓**Autonomous Zone Dynamics:** The 2020 Seattle CHOP zone covered eight city blocks after police abandoned their precinct, initially functioning as a self-organized community with mutual aid stations, free food, and peaceful assembly before internal security tensions emerged rapidly.
- ✓**Vigilante Security Escalation:** Without formal policing, CHOP protesters self-appointed armed security patrols carrying tactical gear and rifles, including AR-style weapons, demonstrating how security vacuums can produce informal armed enforcement structures with no accountability frameworks or training.
Can World Cup mania grow MLS in the U.S.?
- ✓**Host City Leverage:** MLS teams in World Cup host cities, like the New England Revolution, spent years lobbying FIFA to secure local match assignments — Boston landed seven games including a quarterfinal. Live attendance at high-stakes international matches demonstrably shifts skeptical sports fans from "soccer doesn't interest me" to "show me more," making venue selection a multi-year strategic investment.
- ✓**Costco Sampling Strategy:** The Chicago Fire allocated $2–3 million to operate one of the largest World Cup watch parties in a non-host city, occupying an entire city block with 30 screens and a four-sided jumbotron. The goal is collecting fan contact data and exposing casual attendees to MLS players and merchandise, converting one-time visitors into season ticket holders.

→ WHAT IT COVERS The Trump Department of Education caps federal graduate student loans at roughly $21,000 per year starting July 1, 2025, reversing the unlimited Grad PLUS program created in 2006. The policy tests the decades-old "Bennett hypothesis" — that restricting student aid forces universities to lower tuition — against $1.7 trillion in total student loan debt.

→ WHAT IT COVERS The $70 billion U.S. supplement industry operates under regulations so lax that companies need not prove products work or contain labeled ingredients before selling them. Planet Money explores how a 1994 law, consumer backlash, and a jellyfish memory pill expose the regulatory gaps enabling this fast-growing market. → KEY INSIGHTS - **Label language as a red flag:** When a supplement label says "supports" or "promotes" a function — such as "supports metabolism" instead of...
