(dummy variable would equal ‘0’), the effect of wins would be diminished. This belief emerged
from the thought that once a team had a strong fan base, the additional revenues to be gained
would be tougher to obtain than the initial gains, because the team would then have to look for
more creative ways to increase revenues such as better advertising deals and local television
contracts which take a longer time to take effect than gate receipts. If this hypothesis had been
correct, then the interactive variable should have a positive coefficient.
Because this interactive variable has a significantly negative coefficient
, it must be re-
evaluated. There are several reasons why this variable should be negative. Firstly, if a team
could not sell out last year there is a good chance that it is not a top caliber team which would
hurt future season ticket sales. On the topic of ticket sales, if a team was not able to sell out the
previous year, then they will not be able to raise ticket prices in the following year because they
know that demand will not be high enough to warrant a rise in prices. Lastly, a team that isn’t
able to win a lot of games and bring in a lot of fans will not be attractive to corporate sponsors.
These three reasons are epitomized in the Boston Celtics. Before the 2007-2008 season,
the Celtics had been consistently recording a below .500 record. What changed for the Celtics
during the offseason? They acquired two All-Stars in Ray Allen and Kevin Garnett. The first year
these two were acquired, the Boston Celtics went on to win 42 more games than they did the
previous year and secured an NBA championship. With this success, the Boston Celtics were
able to sell out their games that season which situated them for higher profitability in the
future. Even before the season ended, Boston Celtics executives were planning to raise ticket
prices 10-15% for the next season. On top of this, they wanted to sign additional corporate
sponsors, which were estimated to be worth 5 – 10 million dollars
.
Along the same lines, the lagged wins variable has a strong effect on a team’s revenues.
The intuition behind this variable is very similar to the intuition that was just explained using
Negative for all sell out percentages from the cut off of being a “sell-out” of 100% all the way down to 90% of full
capacity.
These two factors: gate receipts and sponsorship deals were specifically important to Boston Celtics team
revenue.
