The phenomenon of match-fixing does constitute a constant element of sport contests. This paper presents a simple formal model in order to explain it. The intuition behind is that an asymmetry in the evaluation of the stake is the key factor leading to match-fixing. In sum, this paper considers a partial equilibrium model of contest where two asymmetric, rational and risk-neutral opponents evaluate differently a contested stake. Differently from common contest models, agents have the option of choosing a second instrument to affect the outcome of the contest. The second instrument is assumed to capture positive investments in ‘contest management’ – namely efforts paving the way for a match-fixing. In particular, it will be demonstrated that, under some conditions, an asymmetry in the evaluation of the stake can lead to a concession from one agent to the other and then to a match-fixing. Eventually the intuitions and results of the model will be applied to make a comparison between the FIFA World Cup and the UEFA Champions League tournaments.
