Do preferences of drinker-drivers differ?

Why people engage in illegal activities is not well understood. Using data collected for this research from eight cities in four states, this study investigates alternative explanations as to why people drive while intoxicated (DWI). We find that preferences and subjective beliefs about arrest/incarceration of persons who drink and drive do differ systematically from others in terms of benefits and costs of drink and driving, and in their risk tolerance. While most findings imply that DWI is a deliberate choice, we do find that drinker drivers tend to be more impulsive and lack self-control in their drinking.
