Nova: Picture this: It's Game 6 of the 1997 NBA Finals. The Chicago Bulls and Utah Jazz are tied with 28 seconds left. Everyone in the arena, everyone watching on TV, knows the ball is going to Michael Jordan. But instead of taking the shot, Jordan passes to Steve Kerr, who sinks the game-winner. Now, was that just great basketball instinct, or was Michael Jordan secretly a brilliant economist?

Nova: That's exactly the argument Paul Oyer makes in his book "An Economist Goes to the Game: How to Throw Away $580 Million and Other Surprising Insights from the Economics of Sports." Oyer is a Stanford economics professor who argues that great athletes, whether they know it or not, are practicing sound economic thinking every time they compete.

Nova: Absolutely. It's what economists call a mixed-strategy equilibrium. Jordan has to pass just often enough that defenders can't simply swarm him every single play. If he took every shot, all five defenders would collapse on him. But by occasionally passing, he keeps them honest. He's optimizing the trade-off between shooting and passing, and that is pure game theory.

Nova: That's one of many surprising revelations we'll get to. Oyer's book is essentially a guided tour through the world of sports using the lens of economics, and he covers everything from why South Korean women dominate golf, to why you should actually love ticket scalpers, to why hosting the Olympics is almost always a terrible financial decision. Today we're going to unpack the most fascinating insights from this book and see sports in a way you probably never have before.

Nova: Let's start with a question every sports-loving parent has asked: Should I push my kid toward professional sports? Oyer opens the book with a deeply personal story about his own son hitting a Little League home run. He talks about how youth sports are both a consumption good, meaning they're fun in the moment, and an investment good, meaning they might pay off later.

Nova: That's the conventional wisdom, but Oyer complicates it with one of the most shocking statistics in the book. He looked at Kevin Durant's income in 2015 and compared it to the total earnings of the roughly 320,000 Black American men born in the same year as Durant, 1988. Durant's income alone represented nearly one percent of all the money earned by that entire cohort.

Nova: One person. And it gets even more striking. About 300 men from that birth cohort played in the NBA or NFL at some point. In 2015, just 184 players from this group earned a combined $410 million in salaries. That represented roughly six to seven percent of all income earned by Black American men born in 1988.

Nova: Oyer's point is exactly that. For someone like Durant, who grew up in a working-class background and was already six-foot-eight by high school, the economic calculation changes dramatically. The opportunity cost of not pursuing basketball was enormous, especially given the labor market constraints facing young Black men. But for most kids, even very talented ones, the math is brutal. The vast majority won't make it, and the hours spent on sports are hours not spent studying or developing other skills.

Nova: He says there are really only two good reasons to invest heavily in youth sports with expectations of a return. One is if it helps get your kid into a good college. The other is if your child is truly, exceptionally gifted, like unusually tall and athletic by age twelve or thirteen. Otherwise, he says, kids should play sports for fun and for the life skills they develop: coordination, teamwork, decision-making. Treat it as consumption, not investment.

Nova: Precisely. And that framework, looking at hidden costs and trade-offs, is the foundation for everything else in the book.

Nova: Here's a trivia question for you, Reed. Which country is, per capita, the greatest sports powerhouse in the world?

Nova: Good guesses, but it's Liechtenstein.

Nova: That's the one. Liechtenstein has won ten Olympic medals, all in Alpine skiing. Now, ten medals doesn't sound like a lot, but when you factor in the population, it's extraordinary. Oyer created something he calls the Population-Adjusted Power Index, or PAPI, to measure this. A PAPI of one means a country has exactly the representation in a sport you'd expect given its population. Liechtenstein's PAPI in women's downhill skiing is a staggering 7,718.

Nova: Not at all. By comparison, China has five of the world's top twenty-five badminton players, but with a fifth of the global population, that's actually about what you'd expect. Their PAPI is around one. Liechtenstein's natural advantage is obvious: it's right in the Alps, kids ski after school, they grow up on the slopes. It's what economists call comparative advantage rooted in natural endowments.

Nova: That's where it gets fascinating. South Korean women have been dominating the LPGA tour for decades. At one point, there were so many players named Lee on the Korean tour that one golfer, Jeongeun Lee, actually goes by "Lee6" professionally, with the six indicating she was the sixth player named Lee to join the tour.

Nova: Oyer traces it to a confluence of economic and cultural factors. First, South Korea has an extraordinarily high household savings rate, which means families have money to invest in things like golf lessons. Second, there's intense academic pressure on children, and sports become a way to stand out. Third, and this is the crucial economic factor, South Korea has one of the largest gender gaps in labor market opportunities among developed countries. For talented, ambitious women, the traditional corporate path is severely limited. Golf represents a genuine path to economic success and independence.

Nova: Exactly. And there's a network effect too. Once the first South Korean woman, Se Ri Pak, became a superstar in the late 1990s, she inspired a generation of young girls who saw a path they could follow. Economics calls this a feedback loop: success breeds imitation, which breeds more success. Today, South Korean women have won a wildly disproportionate share of LPGA major championships.

Nova: Let's go back to Michael Jordan and that pass to Steve Kerr. Oyer devotes an entire chapter to why athletes use their least successful moves so often. It sounds counterintuitive, right?

Nova: Because if they always kicked to their strong side, the goalie would know and would always dive that way. The player has to mix it up. Oyer actually modeled the optimal strategy for penalty kicks using Excel, and what he found is remarkable: elite soccer players come up with strategies that are almost identical to what a computer would calculate, even though they've never taken an economics class.

Nova: That's Oyer's core argument. He says game theory won't make you a great athlete, but an inability to use game theory strategically is enough to keep you from being a great athlete. If you can't figure out the right mix of strategies, you won't survive at the elite level.

Nova: Yes, and this is where the prisoner's dilemma comes in. Oyer tells the story of Rashid Ramzi, a Moroccan-born runner who became a citizen of Bahrain and won Olympic gold in the 1,500 meters in 2008, only to have it stripped after a retest found banned substances. And here's a shocking stat: twenty of the twenty-one Tour de France podium finishers from 1999 to 2005 were linked to doping.

Nova: The prisoner's dilemma works like this: if nobody dopes, everyone competes on a level playing field and nobody faces health risks. But if one person dopes and gets away with it, they gain a massive advantage. So the rational calculation for any individual athlete is to dope, because if they don't, someone else will, and they'll lose. Oyer isn't saying athletes should dope. He's saying that as long as doping is possible and enforcement is imperfect, it's nearly inevitable.

Nova: Oyer does note that doping has declined since stricter testing began around 2008, but he suggests it likely remains widespread at elite levels. The incentives are just too powerful. And he extends this logic to lower-stakes cheating too. He talks about second-tier tennis, where players ranked around 600 in the world, barely making enough to cover travel expenses, sometimes throw matches for as little as a thousand dollars.

Nova: But when you're struggling to survive on tour, a thousand dollars to lose a set you might lose anyway starts to look rational. Oyer was genuinely surprised that there's even a betting market for matches at that level. Some bookie somewhere is taking bets on the 600th-ranked tennis player in the world.

Nova: Alright, Reed, let me ask you: are ticket scalpers good or bad?

Nova: That's what most people think. But Oyer argues that scalpers actually make the world a better place. He tells the story of Amy Stephens, a schoolteacher in suburban Atlanta who built an entire ticket resale empire. And Oyer says fans should love people like her.

Nova: Here's the economic logic. When tickets are initially priced below what people are actually willing to pay, you get a shortage. Think about a playoff game. The team prices tickets at, say, $100, but there are thousands of fans who would pay $300. So what happens? The tickets sell out instantly, and many people who really want to go can't get them. Scalpers step in and reallocate those tickets to the people who value them most, as measured by their willingness to pay.

Nova: Exactly. They create what economists call gains from trade. The person who bought the ticket at face value but would rather have the cash sells to someone who would rather have the experience. Both parties walk away happier. It's a voluntary exchange that increases total utility.

Nova: That's about hosting the Olympics. Oyer dedicates a chapter to why you should be upset if your hometown hosts the Olympics, and the number is staggering. Cities routinely lose hundreds of millions of dollars on these events. The $580 million in the title likely refers to the massive financial losses that host cities incur when politicians prioritize prestige over sound economics.

Nova: Oyer argues the benefits are almost always overstated and the costs are almost always underestimated. Stadiums built with public funds typically have large cost overruns. The infrastructure might benefit the city, but there are far cheaper ways to build infrastructure than hosting a two-week sporting event. And the tourism bump is temporary, while the debt lasts for decades. Oyer points out that these decisions are driven by political incentives: politicians get the glory of bringing the Olympics to their city but don't bear the full financial costs, which fall on taxpayers over many years.

Nova: Precisely. And then there's sports gambling, another market where the incentives are fascinating. Oyer notes that even professional sports gamblers rarely pick winners more than about 55 percent of the time. The house always has an edge, and the math is brutal for casual bettors.

Nova: And that's the professionals. Oyer's advice on gambling is pure economics: bet if it's fun, because the consumption value, the thrill, is real. But don't bet because you think you're going to win money over time. You won't. He also makes a policy suggestion I love: ads for sports gambling should be required to show losers in proper proportion to winners. Every gambling ad shows people winning and celebrating. That's not how it works.

Nova: So what have we learned from Paul Oyer's tour through the economics of sports? First, that great athletes are practicing economists whether they know it or not. Michael Jordan's pass to Steve Kerr wasn't just great basketball, it was a perfectly calibrated mixed-strategy equilibrium. Soccer players choosing which way to kick a penalty shot are solving optimization problems that would make a computer proud.

Nova: We discovered that Liechtenstein dominates Alpine skiing not because its citizens are genetically superior but because they grow up on mountains, giving them a natural comparative advantage. And South Korean women dominate golf because of a complex mix of high savings rates, gender inequality in the labor market, and powerful network effects.

Nova: And perhaps most sobering, we learned that hosting the Olympics is almost always a financial disaster for host cities, driven by political incentives rather than sound economics. Meanwhile, sports bettors face odds so steep that even the pros barely break the 55 percent mark.

Nova: That's exactly right. Oyer says economics is often called the dismal science, but he wants to show it can be fun. And what better vehicle than sports, something billions of people already love? The point isn't to calculate everything. It's to see the world more clearly. As he puts it, you might never watch or play a game the same way again.

Nova: Or at least that's what the economist would say. This is Aibrary. Congratulations on your growth!
