Napoleon Complex: Height Bias Among National Basketball Association Referees
Paul Gift & Ryan Rodenberg
Journal of Sports Economics, forthcoming
Abstract: Given the vast number of observations in a transparent environment, the interaction between players and referees in the National Basketball Association (NBA) provides a real-world laboratory that allows for observation and testing of implicit height-based biases (the so-called “Napoleon Complex”). Controlling for a plethora of referee-specific characteristics and including 4,463 regular season games from 2008 to 2012, we find that (i) more personal fouls are called when a relatively shorter three-person officiating crew is working and (ii) no more or fewer fouls are called when games involve relatively taller players. Such biases are probably not large enough to impact game outcomes but could affect gambling markets. Our findings support the conclusion that relatively shorter NBA referees officiate basketball games differently than their taller peers. The analysis spotlights an oft-suggested but rarely studied bias in a workplace where employees are heavily scrutinized and monitored.

Napoleon complex? Isn't reverse causality a more plausible story -- short refs are less intimidating, so players press them further and then get charged with more fouls. How do authors argue for their version?
Is there a " typo " in the second finding ?
Should it not read as : " no more or fewer fouls are called when games involve relatively taller
" REFEREES " .
Not " PLAYERS " .
" Relatively taller players" seems nebulous in this context .
