| Abstract: | In this model, a mix of public and private provision of private goods arises naturally in the economy. We characterize the social optimum in the presence of a linear tax/public expenditure system and show how a user charge can be welfare- or Pareto-improving, when the users are the poor. The charge discourages the rich from opting into the public program and allows the policymaker to restructure the tax/expenditure system in a way that is beneficial for the poor. If the ensuing welfare gain is large enough to outweigh the loss for the remaining users, a charge is desirable. |
