ImpacTeen Research Papers Peer Effects and
their Role in Binge Drinking across American College Campuses Universities have
widely varying rates of heavy drinking, raising the question, "Do
peers influence individual decisions to binge drink?" This study
measures the effect of peer influences on binge drinking across U.S. college
campuses using the 1997 and 1999 College Alcohol Studies. We find that
a 1 percentage point increase in the level of peer use increases the probability
of binge drinking 0.96 percentage points and frequent binge drinking 0.83
percentage points. By including both price and substance use control policies
in our analyses, we provide evidence on both the direct price/policy effects
on substance use behavior and the indirect price/policy effects that operate
through the peer effect, referred to as the social multiplier. Research
