摘要

The paper considers a two-tier institution in which government provides public services, but individuals can opt out of public provision (but not taxes). Funding for the public service is chosen endogenously by majority vote, and we first provide necessary and sufficient conditions for a majority vote equilibrium. In line with existing results, the equilibrium tax rate usually falls below the one found in a one-tier system (opting out of public consumption is prohibited) as the-public system loses the political support of the rich who exit. We prove that when the two-tier system majority dominates a purely private system, a majority in society always welcomes a transition from a one-tier public system to a two-tier system, it is the only system that is. stable in an evolutionary sense. Otherwise, a majority consisting of the middle class may be in favor of staying in a one-tier system (prohibiting exit) because of a slippery slope argument. (C) 2010 Elsevier B.V.
