This article uses economic theory to examine the variables that affect the competitive balance in a professional sports league and the impact of revenue sharing. The generally accepted proposition that revenue sharing does not affect the competitive balance in a profi t-maximizing league has been challenged by many. It is shown that the competitive balance and the impact of revenue sharing not only depend on the relative size of the market of the clubs, but that they are also affected by the objectives of the club owners and the importance to spectators of absolute team quality and uncertainty of outcome. Furthermore, the clubs’ hiring strategies, including the talent supply conditions, turn out to be important elements affecting competitive balance and the impact of revenue sharing.
