Question

Suppose that I have a theory that traffic fatalities are worse when the roads are icy. So. I think states with more snow will have more fatalities. Would the following methods of measuring the effect of snow on fatalities be sensible? a. I consider a model with average snow for each state (average.snowi) to a model of fatality rates as a function of the beer tax, a sctof dummy variables for the drinking age being 18, 19, or 20. dummy variables for mandatory jail or community service if caught with a high BAC, vehicle miles per driver for thestateTtheunemployment rate, and state andj/car fixed effects. b. I consider the same model as part a, but I add average snow per year for each state (average.snowtt) instead of average snow. I consider the same model as in part a., but I add average snow per year (average.snowt)

Explanation / Answer

The model b is sensible. The average snow per year for each state will make much sense.
