There is none. Interesting discussion.

Rather, the preferred method of measuring competitive balance is looking at the distribution of wins over time. When sports economists do this, they almost invariably find that salary caps, luxury taxes and revenue sharing have no effect on competitive balance. John Vrooman found in his 1995 study that salary caps ironically promote competitive imbalance because it allows the league to behave as one entity, rather than each team acting as an individual firm. Once a league is recognized as a single economic entity, it (shockingly) starts acting like one, and that isn't good from a competitive balance perspective. Once MLB, for example, is a single entity, it's primarily concerned with the health of the entire league. So it institutes policies that may shuffle money around to make unprofitable teams profitable, but it doesn't mandate they become more competitive, as has been the case with the Pittsburgh Pirates, who have (until recently) been lousy on the field for two decades, and yet quite profitable off of it.
But Vrooman's work was admittedly theoretical. For more analytical work, Martin Schmidt and Dave Berri conducted a 2001 study that analyzed competitive balance using a traditional measure of equality, the Gini Coefficient, to measure the relationship between attendance and wins in baseball. To their surprise, they found the 1990s were actually the most competitively balanced decade in baseball history, and there had been a steady trend in that direction for decades. The Gini Coefficient has its problems and limitations, but it's also not the only measure to come to the same conclusion. In his aforementioned book, Bradbury used the Noll-Scully Measure of competitive balance -- which uses the relationships between the average number of wins per team, the number of teams in the league and the number of games each plays -- to measure MLB's historic competitive balance. He found very much the same results as Schmidt and Berri: "Competitive balance today is about what it was in the 1980s, and it's the best it's been in the league's entire history. Recent attempts to improve competitive balance with policies such as revenue sharing and a luxury tax don't appear to have had much effect." Likewise, Berri stated unequivocally in a 2011 blog post: "We found that none of these institutions [salary caps, luxury taxes, etc.] had any statistically significant impact on balance in any of these leagues [NBA, NHL, NFL, and MLB]." These are but a few of a host of studies echoing the same conclusion: league policies don't affect competitive balance to any measurable degree.
Marvin Miller said:No legitimate union could ever agree to a salary cap. In my mind, if a union did that, if would be grounds for decertification, for membership to go court. They were not representing their goal in the law: to improve the wages, hours and working conditions of its members.
