Over the past 15 years, access to EC has been expanded at both the state and federal level. This paper studies the impact of those policies. We find that expanded access to EC has had no statistically significant effect on birth or abortion rates. Expansions of access, however, have changed the venue in which the drug is obtained, shifting its provision from hospital emergency departments to pharmacies. We find evidence that this shift may have led to a decrease in reports of sexual assaultThis is the peer reviewed version of the following article:Gross, T., Lafortune, J. and Low, C.
