Binge Drinking and Risky Sex among College Students

Hot off the press from NBER, I was particularily interested in one of the main conclusions from the abstract:

Results from a rudimentary instrumental variables strategy and accounting for whether sex is immediately preceded by alcohol use suggest that binge drinking directly leads to risky sex. Some binge drinking-induced promiscuity seems to occur among students, especially males, involved in long-term relationships

I could have told you that without doing any econometrics!

Note: I have read nothing but the abstract so can’t comment on the actual econometrics carried out!
