The data that professional sport generates, which is almost unparalleled in any other industry, provides a wealth of information for the economist to analyse. Sport offers economists the opportunity to study the behaviour, choices and outcomes of the decisions of players, referees, regulators and governments. Advances in Sports Economics is a collection of newly commissioned essays that examine a wide range of different sports, including baseball, basketball, cricket, football, horse racing, rugby, tennis and Gaelic games. The contributors consider economic issues such as incentives, rule changes, labour markets, competition structure, gambling, gender equality, match official behaviour, superstar players, funding and sports infrastructure as well as interogating the methods and theories used in sports economics. The essays showcase how the application of economic analysis can provide us with a better understanding of the mechanics of professional sport.
