Abstract
The effects of heavy episodic drinking on studying and grades are modeled separately for college men and women using instrumental variable, simultaneous equation techniques with the 1993 & 1997 College Alcohol Studies data. Binge drinking lowers predicted grades by three tenths of a point for both genders. Current drinking is predicted to increase study hours for women; the effects for men are ambiguous. High school binging decreases study hours for women. The direct effect of drinking on grades remains negative under all robustness checks; the effect on study hours for women is robust to most specifications changes.
