Competitive Balance

Chapter 5

FIFTH EDITION

The Economics of Sports

Trang 3

Learning Objectives

• Understand why owners and fans care about competitive balance

• Be able to use and interpret the different

measures of competitive balance

• Describe and compare the tools that leagues use to promote competitive balance and the limitations of those tools.

Trang 4

5.1 Desire for Competitive

Balance

• Fans and owners alike have a conflicted

relationship with competitive balance

• On any given day, seeing one’s team win is preferable to seeing it lose

• But an uninterrupted string of wins is dull

Trang 5

The Fans’ Perspective

• A game with an uncertain outcome is much more exciting than a foregone conclusion

• Table 5.1 shows that from 1950 to 1958

attendance for both the Yankees and the

entire American League either stagnated or fell because of Yankees dominance

• Evidence suggests that in many sports, fans prefer a game where the home team has a 60-70% chance of winning

Trang 7

The Owners’ Perspective

• Competitive balance matters to owners

because it matters to fans

• Leagues adopt policies to promote competitive balance because they enhance fan demand

• Leagues restrict team behavior if it leads to

teams that are too strong or too weak (see

Table 5.1)

• Balance is hard to achieve if some teams

maximize wins while others maximize profits

Trang 8

Effect of Market Size

• There is considerable debate over the impact

of market size on competitive balance

• There are three primary sources of

disagreement

– How to measure of success

• During playoffs or regular season?

– How to characterize market size

• Market size has become more important with the advent of broadcasting

Trang 9

Effect of Market Size (cont.)

•The third point of disagreement is how to

measure the impact of policies, such as

revenue sharing

•Profit-maximizing leagues do not want total

balance – they want big-market teams to win more

• At minimum, more populous locations will win

the league championship more frequently

• Figure 5.1 shows an additional win is more

valuable in a larger market, so the optimum

Trang 11

The Effect of Diminishing Returns

• The impact of another unit of a variable input (when added to a fixed input) eventually falls

and pay – star players

– And promotes competitive balance

• Drew Brees has limited value to a team that has

Tom Brady

– Brees adds little to wins, attendance, or revenue

– The added cost exceeds the added benefit

– Other teams can use him more effectively

Trang 12

Is Perfect Balance Profit

Maximizing?

• Winning has a bigger

impact in a larger market

– It adds more to gate,

media, and venue

– Big cities will win more

unless MCwins is also

Trang 13

A History of

Competitive Balance

• Yankee dominance of MLB is not new

– Appeared in 15 World Series between 1947 and 1964

• The LA Lakers and San Antonio Spurs won 9 of 13 NBA championships between 1999 and 2011

• The Montreal Canadiens won 10 Stanley Cups in the NHL between 1965 and 1979

– They were succeeded by NY Islander and Edmonton Oiler dynasties in the 1980s

• The NFL is more balanced, but the Browns and

Lions have never been in a Super Bowl

Trang 14

Competitive Balance in Soccer

from 2000-01 to 2011-12

• In England’s Premier League

– Manchester United, Chelsea, and Arsenal have won

Trang 15

5.2 Measuring Competitive

Balance

• Within-Season Balance (Variation)

– Compares teams within a season—across a league

– A low dispersion of team winning percentages means that the teams are evenly matched

• Between-Season Balance (Variation)

– Compares winners (champions) across time

– Some leagues have the same champions year after year

• Regular turnover is preferred

Trang 18

Within-Season Variation (cont.)

• We cannot compare the standard deviation across leagues or across seasons with a different number

of games

• As the number of matches rises, winning

percentages cluster around the mean

– If teams are evenly matched, then the probability of success in any game is close to 5

• We can apply the binomial distribution

• In a short season, a lucky team can have all wins and an unlucky team no wins

• The league can look unbalanced in a short season

Trang 19

Within-Season Variation (cont.)

– We need a better measure

– We compare a league’s standard deviation to the

standard deviation that would result if teams were

Interpreting the Ratio

• The ratio R gives a standardized measure

– Actual and ideal standard deviation fall as G rises

– We can now compare leagues and seasons with a

different number of games

– The formula appears on p 161

• As a rule, R > 1

• If R = 1, the league is completely balanced

– Outcomes are effectively randomly determined

• As R rises, balance worsens

Trang 22

How Do Leagues Compare?

• English Premier League was the most

balanced in 2011-2012

• The NFL, NHL and MLB have similar balance

• NBA is by far the least balanced

– This has been true in most years

• See Table 5.3 for the actual statistics

Trang 23

Table 5.3

Trang 24

– It is unclear what is a good or bad value

• We can use the frequency of championships

– It is hard to compare this across leagues

– See Table 5.4

Trang 26

The Herfindahl-Hirschman Index

• HHI measures the concentration of championships

• In industrial organization, it measures monopoly power

• Let c i = #championships by team i

– T = #teams; N = #Years

– If HHI=1, one team always wins

– If HHI=1/N and N>T, complete competitive balance

– If HHI=1/T and N<T, complete competitive balance

Applying the HHI to Sports

• See Table 5.4

• the HHI for the Premier League is far greater

than for any other league

• the HHI for the NBA is also large

• the HHI for the NHL, NFL, and MLB are

substantially smaller

• the HHI for the NHL is the smallest, indicating

that the league was most balanced in the first decade of the 21st century

Trang 28

Illustrating Competitive

Imbalance

• The Lorenz Curve measures inequality in a

population

– It is typically used to measure income inequality

– We use it to measure inequality in winning

• Line up NBA teams by wins in 2010-2011 (p 164)

– 1230 games were played, so population = 1230

– The 3 weakest teams (the lowest decile) won 58

games

• 58 games correspond to 4.7 % of 1230

• Thus, the bottom 10% accounted for 4.7% of wins

• The next 10% accounted for 5.8% and so on

• The top 10% accounted for 14.7% of wins

Trang 29

The Lorenz Curve for the NBA

• Red line shows perfect

balance

– Adding 10% more teams

adds 10% more wins

• Blue line shows reality

– Bottom 10% wins less

account for 100% of wins

• The farther the blue line

0 0.2 0.4 0.6 0.8 1 1.2

5.3 Altering Competitive Balance

• All the major North American sports leagues have developed policies to promote

competitive balance

– Revenue sharing

– Salary caps and luxury taxes

– Reverse-order draft

• Players claim that the policies merely

depress overall salaries

• This section explores the policies’ effect on

Trang 31

The Invariance Principle

• Free agency allows a player to go to the team that offers the best employment terms

– Players sell their services to the highest bidder

• Owners claim that free agency is incompatible with competitive balance

– Economic theory suggests otherwise

• Markets direct resources to the most productive uses

– Property rights do not affect the flow of resources

– They affect only who gets paid for them

– Simon Rottenberg (1956) first applied the principle to

Trang 32

How the Invariance Theorem

Works

• In 2012 Albert Pujols was more valuable to the LA Angels than

to the St Louis Cardinals in terms of revenue

• With free agency

• The Angels paid Pujols to move to LA

• Without free agency

• The Angels would pay the Cardinals for the “rights” to Pujols

• Pujols moves in both cases—the use of the resource is

unaffected

• The only difference is who gets paid

• The reserve clause did not prevent player movement

• In 1920 Red Sox sold Babe Ruth to Yankees

• Connie Mack twice sold off championship teams in

Philadelphia

Trang 33

With Transaction Costs…

• The Invariance principle breaks down if there are large costs to making transactions

• Benefits that do not exceed transaction costs are not realized

• Transactions costs could have prevented the

Angels from pursuing Pujols

Trang 34

Revenue Sharing

• MLB, NBA, NFL, and NHL share network TV revenue equally

• NFL extensively shares all sources of revenue

– Teams keep only 60% of home gate revenue

– Huge TV package dwarfs other sources

• MLB shares 31% of local revenue (minus

“expenses”)

– Central (non-local) revenue also goes

disproportionately to teams in 15 smallest markets

– They will have to spend this revenue on players

Trang 35

Revenue Sharing (cont.)

• The NBA is expected to vastly increase sharing

– Teams will share up to 50% of local revenue (minus

“expenses”)

• The NHL transfers income to teams

– In bottom 15 smallest media markets

– If the market has a base population under 2 million

Trang 36

Revenue Sharing (cont.)

• Revenue sharing equalizes revenue across teams

• Goal is to reduce incentive of big teams to pursue talent

• This will not work if

– Sharing shifts down MR of a win for all teams equally – big-market teams still have higher MR

– Teams that receive revenue do not spend their added revenue on talent

• Some teams might pursue profit over wins

Trang 37

Salary Caps

• NBA, NFL, and NHL all have salary caps (not MLB)

– Salary caps are neither a salary limit nor a cap

• They set a band on salaries: both upper and lower

limits to payrolls (not individual salaries)

• Take qualifying revenue (QR) of league

– Not all revenue “qualifies”

– Definition varies from league to league

• Players get a defined share of the QR

• Divide total player share by # of teams

• Add & subtract a fudge factor (5-20%) to get the

bounds

Trang 38

NFL Example

• Players receive

– 55% of national broadcast revenue

– 45% of NFL Ventures (merchandising) revenue

– 40% of aggregate local revenues

• Each team must spend at least 89% of the cap

• Overall, players must receive at least 95%

Trang 39

Hard Caps and Soft Caps

• The NFL has a hard cap

– Sets a firm limit on salaries without exceptions

• The NBA has a soft cap with many exceptions

– Mid-level exception

• Team can sign 1 player to the league average salary

• Even if it is over the limit – Rookie exception

• Team can sign a rookie to his first contract

• Even if it is over the limit – Larry Bird exception

• Named for former Celtics great who was its first beneficiary

• Team can re-sign a player who is already on its roster

Trang 40

The NBA and Soft Caps

• All the exceptions have undermined the cap

• This has led to further rules

– The NBA now caps individual salaries as well

– The NBA has a luxury tax to prevent teams from

abusing the exceptions

• This has nothing to do with luxury boxes

• Teams pay a tax that increases for every $5 million over the cap

• A team $15 million over the cap must pay a $37.5 million tax

Trang 41

MLB’s Luxury Tax

• Tax starts at 17.5% for first-time offenders

– Threshold is $178 million in 2011-2013

– Rises to $189 million in 2014

• Tax rises with the number of abuses

• NY Yankees have paid the tax every year

Trang 42

The Reverse-Order Entry Draft

• Ideally, it levels out talent over time

• Teams select new players according to their

order of finish in the previous season

– Weakest teams get the first choice of new talent– Strongest teams get the last choice

Trang 43

What Was the Point of the Draft?

• Did teams just want to keep salaries low?

• Was is a cynical move by weak teams?

– Eagles’ owner Bert Bell proposed the draft

– The Eagles happened to have the NFL’s worst record

• Was it an idealistic move?

– The NY Giants & Chicago Bears agreed to the

Trang 44

Weaknesses of the Draft

• It can lead to “tanking”

– Teams lose intentionally to improve draft position

– That is why the NBA has a draft “lottery”

• Under a lottery

– The weakest team has the best chance of choosing first

– But it might not

• It works only if teams can identify talent

Trang 45

Identifying Talent: Moneyball

• Billy Beane, the Oakland A’s general manager,

found underrated players

• He saw that teams

– Overrated physical skills

– Underrated on-base percentage

• Using different criteria in player selection kept his small market team competitive

• Other teams eventually caught on

– A’s have fallen on hard times as a result
