ABSTRACT [article]
We introduce a model of a local public goods economy with a
continuum of agents and jurisdictions with finite, but unbounded
populations, where the set of possible projects for each jurisdiction/club
is unrestricted in size. Under boundedness of per capita payoffs, which
simply ensures that equal treatment payoffs are bounded above, we apply
results of Kaneko and Wooders (1986) to obtain nonemptiness of the core of
the economy. We then demonstrate, under the stronger condition of strict
small group effectiveness, that the equal treatment core coincides with
the set of price-taking equilibrium outcomes with anonymous prices -- that
is, prices for public goods depend only on observable characteristics of
agents. Existence of equilibrium follows from nonemptiness of the core and
equivalence of the core to the set of equilibrium outcomes. Our approach
provides a new technique for showing existence of equilibrium in economies
with a continuum of agents.
