This research was spurred by the Olympic Training Center’s interest in gathering data to assess the current return on investment for track and field athletes. We predict that athletes who attend the Olympic Training Center should have improved performance in competitions that occur after they have attended the training program. In order to assess these results we have run an endogenous treatment effects model, where we select athletes who have attended the residence program at the Olympic Training Center as participants of the treatment. The Olympic Training Center spends millions of dollars each year to train these athletes, and this study will conclude whether those millions are really worth spending in terms of athletic success.
