This article analyzes the provision of matching services in a model of two-sided search. Agents belong to two heterogeneous populations and are distributed on [0, 1]. Their utility is equal to the index of their mate. In a search equilibrium agents form subintervals and are only matched to...

This paper analyzes the provision of local public goods with positive spillovers across jurisdictions. If spillovers are symmetric, the noncooperative game played by jurisdictions admits a unique equilibrium, and an increase in spillovers reduces the total provision of public goods. Smaller...
