Searching for Illicit Behavior through Changes in Productivity: The Case of Roger Clemens and Performance-Enhancing Drugs John Charles Bradbury1 Abstract Major League Baseball pitcher Roger Clemens has been accused of using performance- enhancing drugs to boost his performance. If Clemens used ergogenic aids consistent with the accusations of use, then unusual changes in productivity may be evident in his performance record. Two previous studies have examined Clemens’s career and reached conflicting conclusions: Bradlow et al. (2008) declares Clemens’s career to be “atypical” while Albert (2009) finds Clemens’s productivity to be unusually strong but similar to other pitchers who have not been linked with performance-enhancing drugs. This study examines Clemens’s performance at times of alleged use and over his career and finds that changes in productivity are not indicative of performance-enhancing drug use.
