Competitive balance and game attendance in major league baseball

This article tests for the effects of a change in competitive balance on attendance at Major League Baseball games using game-level attendance data for the 2000-2002 seasons. Employing the difference between the winning percentages of the home and visiting teams as a measure of competitive balance, the authors find (a) the effects of a change in competitive balance on attendance are not symmetric, (b) the effects of a change in competitive balance increase as a team falls further behind the divisional leader, and (c) the effects of a change in competitive balance decline throughout the season if the home team has a better record than the visiting team but increase if the home team has a worse record than the visiting team.
