Understanding the Economics of the NBA Regular Season

Why the NBA Regular Season does matter

NBA media and other folks have been touting the regular season as much too long and relatively dull. They say the stakes for an individual game are simply too low.

There are several factors that play a part in this viewpoint. First, there are 82 games spanning the course of 7 months, the longest of all major U.S. professional sports. Because of its length, the NBA competes with College Football bowl games, the NFL regular season, the NFL playoffs, and even NCAA March Madness.

“Load Management” has also taken hold, suggesting that the value of winning an individual game can sometimes be so low that players are better off “preserving themselves” for a potential playoff run, and thus sit out of some of these games (often times during back-to-back scenarios).

When turning to the quantitative metrics, the case that the regular season is too long only becomes stronger. FiveThirtyEight uses a metric to understand how much information each game in the regular season carries, determining the point in the regular season where a team’s record represents 50% luck and 50% skill. There are some striking discrepancies across major U.S. professional sports – in the NFL it takes 11 games, the MLB 67 games, and the NBA a strikingly low 12 games.

Taking this argument a step further, you would only need a 17.5 game regular season in the NBA to provide as much information about each team as the 16 game NFL regular season. Nobody is advocating for that short an NBA regular season, but the point rings true – it’s clear that from a competitiveness standpoint, the NBA regular season appears to be way too long. So what justifies its length?

The primary allure and unique feature of sports is the competitiveness aspect, namely uncertainty in the outcome of a matchup and designed parity across a league. For instance, a study analyzing Monday Night Football games found that TV ratings are primarily determined by a quality match-up between winning teams, a high level of uncertainty of outcome, and high-scoring (Paul and Weinbach 2007). The same finding is true in College Football BCS games, where ratings increase systematically throughout a contest when the outcome of that contest becomes more uncertain (Salaga and Tainsky 2013).

Yet, one of the important distinctions between the NBA and most other professional leagues (potentially excluding European soccer) is the starpower of the players, and how their popularity drives viewership independent of the competitiveness or of the quality of the two teams in a game. In fact, our research finds that the competitiveness of a single matchup (as measured by the point spread) isn’t a significant predictor of ticket prices or TV ratings in regular season NBA games.

While this isn’t a one-to-one comparison with the broader metric of how good each team is (as measured by their W-L record or playoff probability), which our research shows to be a strong influencer in ticket prices (and less so in ratings), it is an indicator that there are other important factors driving demand for the NBA regular season product.

On the other hand, popularity of players in a matchup is a huge driver of ticket prices and ratings. In fact, it can be even more important than the combined quality of the two teams playing! Have you ever gone to a game and seen Michael Jordan or Kobe Bryant in person? How about LeBron James or Steph Curry? These are the most talented, most skilled, most explosive athletes this planet has ever seen, and their presence alone is worth the price of admission. There is a “superstar” effect that transcends the competitiveness of a game, how good the two teams playing are, and the market size of each team, among other factors, which makes the NBA a uniquely different product than hockey, baseball, and even football.

The set of “hockey stick” graphs below reinforce this point. In economics, the nature of a superstar is represented by huge increases in value as you move towards the most talented individuals in an industry (shown in seminal research by one of the most well-known economists in history, Sherwin Rosen).

As you can see here, once you start to move into the top 10-15 players from a popularity standpoint (as measured by their All-Star fan votes over the 2017-18 and 2018-19 NBA seasons), the increases in ticket prices and TV ratings become sizable and significant. For instance, in games LeBron James plays in, the average ticket price increase compared to a typical game is on the order of 20-25%. We see similar effects with some of the other most popular players, including Luka Doncic and Stephen Curry.

The fact that there are 82 chances in a regular season (and 41 at home) to see these athletes perform, regardless of the other conditions surrounding the game, should be accounted for when we make arguments about the regular season. It’s also evident that the “number of chances” to see the most popular players matters – while the average impact on ticket prices when LeBron or Steph don’t play is between $30-42 per ticket, when they miss away games the price impact ranges from $55-75 per ticket (Kaplan et al. 2019).

Now, the new age of load management has thrown a sizable wrench into this construct. There is a case to be made that the regular season is indeed too long if the top stars are going to take nights off (or choose not to play with minor injuries that players used to play through), which is a shared sentiment among some writers. Under these conditions, the product no longer has the appeal it’s designed to produce, and fans paying hard-earned money or advertisers expecting a certain number of viewing households are now experiencing reduced value.

These factors may suggest benefits of a slightly shorter regular season (which the NBA has already suggested) to avoid back-to-backs and space out games a bit. This way, expectations about the quality of the product can be better met for the several important stakeholders involved.

The most important takeaway is this: fans pay for the game-day experience. Who could possibly get tired of watching LeBron James or Stephen Curry play, no matter how good the other team, no matter how competitive the game, and no matter how the game may or may not impact playoff probability? More than any other professional sport, this is what makes the NBA different. The players are on center-stage, their athleticism on full display. More specifically, there are only 5 players on the court at a time, and each is perfectly visible (unlike football or hockey).

The narrative needs to be changed, and all of the factors considered. The regular season does matter to a whole lot of people that can’t afford to go to playoff games, or only get a chance to go to one or two games a year (and even that comes with a very high cost). The more chances we have to do that, the more reasonable are ticket prices and the more accessible the stars.

A longer regular season also makes sense for the stars themselves! Player salaries hinge on these revenues, and a much shorter schedule is going to have significant financial impacts. Relatedly, a significantly shorter schedule would reduce the window in which players receive national attention. With the current setup, players get to brand themselves for 9-10 months out of the year, something that doesn’t happen in other professional sports.
