Alcohol-control policies and motor-vehicle fatalities ABSTRACT (excerpted from Introduction and Background) This study
will estimate the effects of deterrence laws and other
alcohol-control policies on drunk driving. Prior research
does not provide an unambiguous assessment of these laws'
effects. Many early studies used interrupted-time-series
analysis, which may not be the most-appropriate method. Most
also consider only one law. This study, however,
simultaneously estimates the effects of all major
drunk-driving laws, minimum legal drinking ages, and alcohol
excise taxes. The article also makes novel use of an
estimated alcohol-involved-driver fatality rate. We
constructed this variable using information on the
blood-alcohol concentration (BAC) of drivers killed in
crashes. We used an annual time series of state cross
sections to estimate these models. This type of data set
allows us to estimate effects more subtle than those
detected with a univariate time series.
