Påverkar grupptryck beslutsfattande? : Belägg från allsvenska domare

Sammanfattning: This paper studies the effects of peer pressure in relation to football audiences’ possible impact on how the referees judge. The data used is new data from the highest Swedish football league, Allsvenskan, for the seasons 2016-2018. The paper treats the problem with the size of the audience not being random by using weather as an instrument. The OLS-estimations suggest that the referee is affected by the audience in the sense that more spectators increase referee stringency. The IV-estimations are precise and close to zero suggesting that it is important to account for omitted variables when studying the effect of peer pressure on referees.
