International hostility and aggressiveness on the soccer pitch: Evidence from European Championships and World Cups for the period 2000–2012

Abstract

Some researchers consider soccer matches as the stylization of a war in other battlefields. Such an approach has largely been used to interpret the violent phenomena related to the soccer environment, while less attention has been paid to the potential role of political and economic interactions between countries in determining the aggressive attitude of players on the pitch. In our paper we empirically investigate whether and how political hostility among countries reverberates on a soccer pitch by influencing players’ aggressiveness. The analysis focuses on official matches played by national teams in the final phases of the European and World Cup tournaments since 2000. We estimate a negative binomial regression including both political and sport variables, and we find that (a) commercial hostility, (b) the level of diplomatic relationships, (c) power asymmetry and (d) education gap between countries are positively and significantly associated with aggressiveness of the players on the pitch, approximated by the number of yellow and red cards. That is, briefly stated, international hostility reverberates onto the pitch. Moreover, sport covariates present the expected signs, namely, results show that the closeness of the teams, their ranking and the stage of the game (knockout stages with respect to the group phases) are also crucial in determining the cautions.
