Home advantage in European international soccer: which dimension of distance matters?

To this end, the authors analyse 2,012 recent matches played in the UEFA Champions League and UEFA Europa League by means of several regression models. They find that when the home team plays at a higher altitude, they benefit substantially more from their home advantage.

Every 100 meters of altitude difference is associated with an increase in expected probability to win the match, as the home team, by 1.1 percentage points. The other dimensions of distance are not significantly associated with a higher or lower home advantage. By contrast, the authors find that the home advantage in soccer is more outspoken when the number of spectators is higher and when the home team is substantially stronger than the away team.
