The Canseco Effect?

The economists Eric Gould and Todd Kaplan have used data to evaluate Jose Canseco‘s claim that he taught many teammates to use steroids and growth hormones. “[A]fter playing with Canseco, players hit more home runs and otherwise boosted their numbers in the areas most affected by steroid use,” writes Ray Fisman in Slate. Furthermore, “the Canseco effect disappears after 2003, when baseball instituted random drug testing and punishments for those found guilty.” [%comments]
