Soccernomics by Simon Kuper and Stefan Szymanski

Freakonomics meets Moneyball meets Fever Pitch in this wholly engrossing 400-plus page analysis of certain questions such as why some countries are successful at soccer while others fail, why discrimination still exists in the hiring of coaches, and why the American soccer story has been a largely successful one overall. Soccernomics has been updated a handful of times since the first edition came out in 2009, and this latest, “2022 World Cup Edition” takes a broader look at the history of women’s soccer around the world — it’s successes and failures, how far it’s come and how far it still should be able to go — along with updated materials on the effect of the COVID pandemic on soccer revenue and how our disparate viewing patterns influences the game today. I’m not a massive soccer fan although I do enjoy watching the occasional World Cup match every handful of years, but one thing that is truly striking about the “world’s game” is the level of fandom that pops out of the screen whenever a Premier League game is broadcast on TV or even in a casual viewing of Welcome to Wrexham, the fully captivating documentary series of Ryan Reynolds and Rob Mcelhenney taking over ownership of the Wrexham soccer club in northeastern Wales. Soccernomics is really a must-read for any sports executive who wants to learn how to make better, smarter decisions with his or her team because a lot of the material is transferable to other sports, as Kuper and Szymanski do a nice job of referencing American football and baseball while keeping their focus on futbol. Or if you are simply a crazed soccer fan who gets enraged when your team trades its best player or fires a manager for no reason, Soccernomics is the perfect book for you as well.

  • Zipfs Law, giants, whether giant cities, soccer clubs, are rare
  • once a city becomes a giant, it is unlikely to shrink into the middle ranks unless it experiences a long series of repeated misfortunes
  • by contrast, a small cities are unlikely to ever become giants
  • “law or proportionate growth”

  • most “successful” suicides are males
  • sport is the most important communal activity in many people’s lives
  • fewer people kill themselves while the national team is playing in a World Cup or a European Championship
  • uniting effect of the tournament lasted for a while afterward, continuing to depress the suicide rate

  • you can get social cohesion even from losing
  • it’s not the winning, but the taking part, the experience
  • “pulling together”
  • sense of belonging
  • that is the lifesaver

  • overall, these events are a force for good
  • hosting world cup’s don’t make your rich, but they do make you happier
  • public investment in stadiums does not provide a good return for taxpayers
  • for every dollar going in, there is probably a dollar going out somewhere else
  • hosting sports tourneys doesn’t increase the number of tourists or full time jobs, or the total economic growth
  • lots of money doesn’t in itself make you happy
  • what we care about is our rung on the ladder
  • extra income is really valuable when it lifts people away from sheer physical poverty
  • people gain a lot of happiness after hosting a tourney, they seem to lose a little happiness in the run up
