Self-Insurance and Self-Protection as Public Goods

Many public goods provide utility by insuring against hazardous events. Those public goods can have self‐insurance and self‐protection character. For both situations we analyze the efficient public provision level and the provision level resulting from Nash behavior in a private provision game. We consider the interaction of public goods as insurance devices with market insurance. The availability of market insurance reduces the provision level of the public good for both public and private provision, regardless of whether we consider self‐insurance or self‐protection. Moreover, we show that Nash behavior has always a larger impact than the availability of market insurance.
