Competitive balance is the degree to which the teams in a league are close enough in strength that any of them can realistically win, so results stay uncertain. Sports economists study it together with uncertainty of outcome in team sports such as baseball and soccer [1]. Leagues try to protect it with tools such as salary caps, drafts and revenue sharing [1].
Key points
- Balance describes how evenly talent is spread across a league, not how good the league is.
- Economists treat it as part of the uncertainty of outcome that makes sport worth watching [1].
- Leagues use salary caps, drafts and revenue sharing to protect it [1].
- Research links balance to attendance: one MLB study found a relationship between the two [2].
Origin
The idea comes from sports economics. Simon Rottenberg’s 1956 paper on the baseball players’ labor market is an early landmark in the field [3]. In 1964 Walter Neale described the “Louis-Schmeling paradox” in his article on the peculiar economics of professional sports: a sports team needs strong rivals, so it cannot behave like an ordinary monopoly [4]. Later work, such as Stefan Szymanski’s 2003 review, covers research on uncertainty of outcome and competitive balance in team sports [1].
How it works in sports media
One study found a relationship between competitive balance and aggregate attendance in Major League Baseball [2].
Examples
- Salary caps. Caps keep costs down and protect balance by stopping richer clubs from entrenching dominance through signing many more top players than their rivals [5].
- Competitive balance tax. Major League Baseball uses a luxury tax, also called a competitive balance tax, instead of a salary cap [5].
- MLB in the 1990s. Schmidt and Berri found that, against MLB’s historical record, the 1990s was the most competitive decade on the field, contrary to the contentions of the media [2].
Common questions
What does competitive balance mean?
It means that teams in a league are close enough in strength that the outcome of games and seasons stays uncertain [1].
How do leagues protect it?
Common tools are salary caps, draft rules and revenue sharing [1]. MLB uses a competitive balance tax rather than a cap [5].
Does balance affect attendance?
One study of Major League Baseball found a relationship between aggregate attendance and competitive balance [2].
