The numbers bear out Mickelson's observations. By 2008 purses totaled $292 million, representing an increase of 9.3% per year since Tiger joined the Tour. This difference in the growth in prize money from 3.4% in the years before Tiger joined the Tour to 9.3% in the years after can be called the 'Tiger Woods effect." I was curious as to what financial impact the "Tiger effect" had on his peers, so I looked at the data.
The results are astonishing. Tiger effectively more than doubled the prize money for every other golfer, adding billions of dollars to fellow players' pockets. How can we demonstrate this?
Here is what I did. I considered all players who earned a pay cheque on the Tour in 2013. I then calculated their total earnings from 1997 to 2008 (176 players). I then calculated how much of those earnings were due to the "Tiger Woods effect" under the assumption that golf purses would have grown at the earlier rate of increase. I then subtracted this value from what they actually earned leaving a residual due to the "Tiger Woods effect."
Other assumptions are of course possible, but the overall conclusions will be much the same Tiger's peers have benefited enormously in competition from his successes, even though Woods himself took home almost $100 million in prize money over that period.
