En palabras de Steven Levitt:
"California Governor Arnold Schwarzenegger is one politician who can credibly claim that he is truly responsible for reducing crime, at least if you believe a new study by economists Gordon Dahl and Stefano DellaVigna. It isn’t his policies as governor, however, that he can take credit for, but rather his acting roles."Estos son los resultados que encuentran los mencionados economistas:
"Laboratory experiments in psychology find that media violence increases aggression in the short run. We analyze whether media violence affects violent crime in the field. We exploit variation in the violence of blockbuster movies from 1995 to 2004, and study the effect on same-day assaults. We find that violent crime decreases on days with larger theater audiences for violent movies."Este es el post original en Freakonomics.
