The outcome from legalizing Sunday packaged alcohol sales on traffic accidents in New Mexico

We attempt to disentangle the effect on alcohol-related accidents and fatal crashes when New Mexico lifted its ban on Sunday packaged alcohol sales on July 1, 1995. Using crash incidents between January 1990 and December 2005, from data maintained by the Division of Government Research in New Mexico, we estimate a negative binomial model that controls for unobservable factors affecting overall accidents. One of these factors is an increase in New Mexico's speed limits in 1996. We find no statistically significant increase in total alcohol-related accidents or alcohol-related fatal crashes on Sundays after the repeal of the ban.
