Summary

An Economist Goes to the Game

Are ticket scalpers actually good for the economy? Should you encourage your child to pursue the unlikely career of a professional athlete? Why are certain small nations disproportionately dominant in specific sports? In An Economist Goes to the Game, Stanford economist Paul Oyer tackles these questions by viewing the wide world of sports through the lens of microeconomic theory. Oyer demonstrates that the same forces that drive stock markets and global trade-opportunity costs, incentives, game theory, and supply and demand-also dictate the behavior of athletes, coaches, and team owners.

Should You Invest in Your Kid Becoming a Pro Athlete?

The book opens with a dilemma familiar to many parents: how much time and money should be invested in youth sports? Oyer argues that while the potential payouts are astronomical, the probability of success is vanishingly small. He uses the example of Kevin Durant and the cohort of African American males born in 1988 to illustrate this point.

Among approximately 320,000 Black men born in that year, nearly 300 reached the NBA or NFL. While this is a small number, the financial rewards are immense. In 2015 alone, 184 players from this group earned $410 million in salaries, representing 6 to 7 percent of all income earned by Black American men born that year. For those with limited alternative economic opportunities, the risk-reward calculus of pursuing sports can be rational. However, for the average family, the economic return on investment in travel teams and private coaching is often negative. Oyer suggests that while sports are valuable for fun and fitness, treating them primarily as a financial investment is generally a losing bet compared to the lottery.

The Globalization of sports and Comparative Advantage

Why does South Korea dominate women’s golf, while Norway produces the world’s best cross-country skiers? Oyer explains these anomalies through the economic concepts of comparative advantage and resource allocation.

South Korean women dominate the LPGA because of specific cultural factors. Intense academic pressure and high savings rates in South Korea, combined with gender inequality in the labor market, make golf an attractive and viable career path for girls. Conversely, Norway’s dominance in skiing is partly a result of natural advantages-specifically, an abundance of snow-and a culture that encourages outdoor participation from a young age. The book introduces the Population-Adjusted Power Index (PAPI) to quantify this dominance, showing that small nations like Liechtenstein and countries in East Africa become powerhouses by specializing in sports where they hold a genetic, geographic, or cultural edge.

The Prisoner’s Dilemma of Doping

One of the most compelling applications of game theory in the book is the analysis of performance-enhancing drugs. Oyer describes the cycling world of the late 1990s and early 2000s as a classic prisoner’s dilemma. If a cyclist believes their competitors are doping, their own choice is to either dope and compete fairly or stay clean and lose.

Because the incentives were structured to reward winning above all else, and for a long time the enforcement was weak, the dominant strategy was to cheat. Twenty of the twenty-one Tour de France podium finishers from 1999 to 2005 were linked to doping. It was only when stricter testing protocols were introduced around 2008 that the incentives shifted. Oyer notes that while doping may have declined, the economic pressures to cheat remain high at the elite level, illustrating that bad systems can force good people to make bad choices.

Randomizing Your Strategy

Economics is not just about markets; it is about strategic interaction. Oyer highlights how great athletes, even without formal training in economics, intuitively grasp game theory. He uses the famous example of Michael Jordan passing to Steve Kerr for the championship-winning shot in 1997.

Jordan was the best player on the court, so one might expect him to shoot every time. However, game theory dictates that if he always shoots, the defense would collapse entirely on him. To maximize the team’s scoring probability, Jordan had to pass the ball just enough to keep the defense honest. This concept of “mixing strategies” explains why athletes often use their least successful moves. By randomizing their behavior, they prevent opponents from predicting their actions, which optimizes their long-term success even if it leads to a missed opportunity in the short term.

The Defense of Ticket Scalpers

Oyer dedicates a chapter to defending one of the most reviled figures in sports: the ticket scalper. He argues that scalpers provide a valuable service by ensuring tickets end up in the hands of those who value them the most. Through dynamic pricing and arbitrage, scalpers help balance supply and demand.

When teams sell tickets at fixed prices that are too low, they often sell out instantly, depriving the team of additional revenue and forcing fans to wait in line or miss out. Scalpers absorb the risk of holding inventory and facilitate price discrimination, allowing fans with higher willingness to pay to secure seats, often at the last minute. While the practice is legally contentious, the economic reality is that scalpers improve market efficiency and can actually help teams fill arenas for less popular games.

The High Cost of Hosting the Olympics

The final sections of the book tackle the business of mega-events. Oyer argues that hosting the Olympics, the World Cup, or building new stadiums for professional teams is rarely a good financial decision for the host city.

These projects are often sold on the promise of economic development and prestige, but the data shows they rarely deliver a positive return on investment. Instead, they are frequently driven by the political interests of leaders rather than the economic interests of taxpayers. Oyer points to the “sports ratchet” effect, where cities fear losing a team to another city that will offer a better stadium deal, leading to a cycle of public subsidies. He concludes that unless you are a politician seeking prestige, you should likely be upset if your hometown wins the bid to host the Olympics.

Conclusion

Ultimately, An Economist Goes to the Game argues that sports are a perfect laboratory for understanding economics. From the labor market decisions of athletes to the gambling behaviors of fans, economic incentives shape every aspect of the games we watch and play. By understanding these underlying principles, fans can become more informed consumers, parents can make better investment decisions for their children, and voters can see through the bluster of stadium deals.
