We show that professional soccer players exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that a player breaches the rules of the game, measured by the referee's assignment of cards,...

The theoretical impact of genetic diversity is ambiguous since it leads to costs and benefits at the collective level. In this paper, we assess empirically the connection between genetic diversity and the performance of sport teams. Focusing on football (soccer), we built a novel dataset of...
