New in paperback. Hardcover was published in 2022. Economics explains why some sports cannot stop the use of performance-enhancing drugs while others can, why hundred-million-dollar player contracts are guaranteed in baseball but not in football, how one man was able to set the world of sports betting on its ear - and why it will probably never happen again. This book is an entertaining guide to how a bit of economics can make you a better athlete and a more informed fan.
