Description

Wooldridge Source: Data from the National Highway Traffic Safety Administration: “A Digest of State Alcohol-Highway Safety Related Legislation,” U.S. Department of Transportation, NHTSA. I used the third (1985), eighth (1990), and 13th (1995) editions. Data loads lazily.

Usage

Format

A data.frame with 153 observations on 5 variables:

• state: state postal code

• year: 85, 90, or 95

• admnrev: =1 if admin. revoc. law

• daysfrst: days suspended, first offense

• daysscnd: days suspended, second offense

Notes

This is not so much a data set as a summary of so-called “administrative per se” laws atthe state level, for three different years. It could be supplemented with drunk-driving fatalities for a nice econometric analysis. In addition, the data for 2000 or later years can be added, forming the basis for a term project. Many other explanatory variables could be included. Unemployment rates, state-level tax rates on alcohol, and membership in MADD are just a few possibilities.
