In a simple public good economy, we propose a natural bar- gaining procedure, the equilibria of which converge to Lin- dahl allocations as the cost of bargaining vanishes. The pro- cedure splits the decision over the allocation in a decision about personalized prices and a decision about output...

If raising and educating children is a private cost to households, while the availability of skilled labor supply resulting from the households' fertility and education choices is a public good, then competitive equilibria typically deliver a suboptimal mix of size and skills of the population....

We consider in this paper overlapping generations economies with polution resulting from both consumption and production. The competitive equilibrium steady state is compared to the optimal steady state from the social planner's viewpoint. We show that any competitive equilibrium steady state...

In a simple public good economy, we propose a natural bargaining procedure whose equilibria converge to Lindahl allocations as the cost of bargaining vanishes. The procedure splits the decision over the allocation in a decision about personalized prices and a decision about output levels for the...

We investigate the welfare properties of the one-sctor neoclassic growth model with uninsurable idiosyncratic shocks. We focus on the constrained efficiency notion of the general equiibrium literature, and we demonstrate constrained inefficiency for our model. We provide a characterization of...

This paper establishes, in the context of the Diamond (1965) overlapping generations economy with production, that the risk that savings in unbacked assets (like fiat money or public debt) become worthless implies that, not only the first-best steady state, but even the best steady state...

I show in this paper that in an overlapping generations economy with production à la Diamond (1970) in which the agents can only save in terms of capital (i.e. with not asset bubbles à la Tirole (1985) or public debt as in Diamond (1965)), there is a period-by-period balanced fiscal policy...

In an overlapping generations economy setup we show that, if individuals can improve their life expectancy by exerting some effort, costly in terms of either resources or utility, the competitive equilibrium steady state differs from the first best steady state. This is due to the fact that...
