“…This is primarily because for most sports detailed statistics of player performance measuring individual productivity are available, and in many such environments the customer is the sole actor, allowing researchers to attribute any unexplained earnings differentials to customer discrimination. 2 For example, customer racial discrimination has been examined in professional baseball by looking at the market for baseball cards (e.g., Nardinelli and Simon 1990;Andersen and La Croix 1991;McGarrity et al 1999;Scahill 2005), Hall of Fame and all star voting (e.g., Desser et al 1999;Hanssen and Andersen 1999), and game attendance (e.g., Hersch 2010); in professional basketball by looking at the market for basketball cards (e.g., Stone and Warren 1999) and Nielsen ratings of locally televised games (e.g., Kanazawa and Funk 2001); in professional football by looking at the market for football cards (e.g., Primm et al 2010); and, in college basketball by looking at gate revenues (e.g., Brown and Jewell 1994), all with mixed results. This paper examines customer gender discrimination in a novel setting: restaurant tipping.…”
