Question
Suppose that I have a theroy that traffiic 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 set of 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 the state, the unemployment rate, and state and year fixed effects.
b) I consider the same model as in part a, but I add average snow per year for each state (average_snowit) instead of average snow.
c) I consider the same model as in part a, but I add average snow per year (average_snowt) instead of average snow.
Explanation / Answer
c) I consider the same model as in part a, but I add average snow per year (average_snowt) instead of average snow.
