Models on private provision of public goods typically involve a single private good and linear production technology for the public good. We study a model with several private goods and non-linear (strictly concave) production technology. We revisit the question of “neutrality” of government...

We consider a model with real assets and restricted participation described by household specific price dependent short selling constraints. We show existence of equilibria for all elements in an explicitly characterized large subset of the set of economies.

We consider an incomplete market model with numeraire assets. Each household faces an individual constraint on its participation in the asset market. In related literature, the constraint is described by a function whose sole argument is the asset portfolio. On the contrary, in our analysis the...

In this paper the existence of unemployment is partly explained as being the result of coordination failures. It is shown that as a result of self-fulfilling pessimistic expectations, even at Walrasian prices, a continuum of equilibria results, among which an equilibrium with approximately no...

We study an economy with competitive commodity markets and exclusive pairwise contractual relations with moral hazard, where both the principal and the agent can be risk averse. We show existence of equilibria and their generic constrained suboptimality,

In this paper we compare rational expectations equilibria with different degrees of information revelation through prices. These equilibria arise in a two-period exchange economy with finitely many states and signals, multiple commodities and incomplete f
