The rules of the game determine how the game is played. Incentives matter. These are obvious but important concepts when designing sports leagues (or public policy implementations). When I think about how teams and players make decisions, I often come back to these fundamental concepts. The league sets the rules and then players and teams make decisions that maximize their individual benefits.
Examples are abundant. Teams “tank” to get better draft choices. Tanking occurs because losing more games results in getting better future talent. Teams cut veterans and go with younger players who are not yet eligible for free agency. Teams shift to rookies because these players have less bargaining power and are cheaper.
The research linked to on this page reports the results of analyses related to revenue sharing in Major League Baseball. The research was conducted at a time when the league was concerned that the Yankees would dominate the league by out spending other teams. While this fear has faded it is a classic issue in sports – teams with better brands and revenue potentials can outspend small market rivals.
Baseball’s answer to this was to develop a system of revenue sharing that penalized teams for exceeding some “luxury” threshold. The problem was that this system created an incentive for teams to become less competitive on the field. Again, it is a simple idea. If you create an incentive for poor performance (transfer payments based on local revenues or better draft picks for losing more games) you will get more “poor” performance. The problem with such a system is that you can reduce competitive balance. Competitive balance matters if you believe that it’s important for every team to have a chance at being a winner.
To study the issue, I created a structural dynamic programming model of team’s decision making. This is a statistical model that captures how dynamic concerns such as building a fan base and short-term preferences for winning influence team’s decisions of how much to invest in payroll.
The results suggest that the key to avoid “tanking” is to base revenue sharing on winning and population rather than on local revenues. In other words, create incentives for being competitive rather than incentives for losing.
The research is reported in two forms. The first is a link to a New York Times piece that explains the results to a general audience. The second is a link to the academic paper in the Journal of Marketing Research. This one provides the full details and shows some hardcore sports analytics.
