We introduce a methodology for analysing infinite horizon economies with two agents, one good, and incomplete markets. We provide an example in which an agent's equilibrium consumption is zero eventually with probability one even if she has correct beliefs and is marginally more patient. We then...

This paper argues that the introduction of a short-sale constraint in the Arrow-Radner frameworkinvalidates standard definitions of complete and incomplete markets. In this constrained set-up,two threshold values with familiar properties arise.The case of a zero short-sale bound set on some...

The purpose of this paper is to explore how the concept of a Drèze equilibrium can be extended to multiperiod production economies with incomplete markets. Constrained efficiency cannot serve as a basis for such an extension because multiperiod models tend to violate even weak constrained...

We consider economies with incomplete markets, one good per state, private ownership of initial endowments, a single firm, and no assets other than shares in this firm. In this simple framework, arbitrarily small income effects can render every market equilibrium resulting from some production...

Positional goods and public goods share the characteristic of “publicness” in terms of consumption; i.e., given the consumption of one party, in the case of a positional good, the other must consume a corresponding negative amount of what the first party consumes, while in the case of public...

In recent years, some Canadian politicians and powerful interest groups have issued increasingly vocal calls for dramatic regulatory interventions into the country's payment cards system. In particular, they have called for a "hard cap" price-controls on interchange fees, a ban on contractual...

In the present paper we study the efficiency properties of competitive equilibria in economies with hidden action and multiple goods. We borrow the description of the economy from Lisboa [3] and we apply a method of proof close in spirit to the one used in the literature on incomplete financial...

In this paper we use global analysis to study the welfare properties of general equilibrium economies with incomplete markets (GEI). Our main result is to show that constrained Pareto optimal equilibria are contained in a submanifold of the equilibrium set. This result is explicitly derived for...

We show that for generic economies, every equilibrium admits Pareto improving monetary policy, even with multiple commodities per state.The main assumption is that asset incompleteness be intermediate, in that household heterogeneity does not exceed the number of assets present and absent.We...

Focusing on tax policy with incomplete asset markets, we create a framework for proving the existence of Pareto improving taxes, for computing them, and for bounding the improvement.The protagonist is the price adjustment following an intervention. If the price adjustment is sufficiently...
