摘要：

In insurance markets, the uninsured can generate a negative externality on the insured, leading insurance companies to charge higher premia. Using a novel panel data set and a staggered policy change that introduces exogenous variation in the rate of uninsured drivers at the county level in California, we find that uninsured drivers lead to higher insurance premia: a 1 percentage point increase in the rate of uninsured drivers raises premia by roughly 1%. We calculate the monetary fine on the uninsured that would fully internalize the externality and conclude that actual fines in most US states are inefficiently low.
