Abstract

This paper examines how tax deductions related to uninsured personal losses may be Pareto-improving if there are inefficiencies in insurance markets in the context of adverse selection by including individuals with different risk types. In the absence of moral hazard, we provide a positive view of loss deduction policies by showing that they more easily reach a separating equilibrium than does the free market in the Rothschild and Stiglitz equilibrium concept.
