A critical mass of corruption: why some football leagues have more match-fixing than others

This paper examines what drives match-fixing in football and why some leagues collapse from corruption. Based on more than 220 interviews with players, referees, sports officials and law enforcement officers, the gambling industry and corrupters, three factors presented when high levels of match-fixing were observed: strong illegal gambling networks, high levels of relative exploitation of players, and perceived corrupt officials. Leagues collapsed if the public became aware of high-level corruption and an alternative market competitor was introduced.
