It is well known that a competitive equilibrium may fail to exist when preferences are possibly satiated. We show that this non-existence problem does not arise if one of the commodities is paper money. Moreover, and equilibrium is weakly Pareto efficient in the economy with money. This paper therefore gives an economic solution to the classical problem of non-existence of competitive equilibri...

In the present paper, the issue of the existence of optimal barter steady states is addressed in a stationary overlapping generations model with many commodities and many different long-lived consumers. A general characterization of the individual endowments leading to an optimal barter steady state is obtained. The result, which is a generalization of Benveniste and Cass (1986), is obtained as...

Consider a two-period situation. In the first period a consumer and a firm bargain over the price of a bond. The objective is a project which takes one period to come on stream. Both agents prefer production but the consumer is less patient than the firm. The outcome is underproduction. A condition for the intervention of a bank exists. It is shown that intermediation is unstable. The potential...

Lotteries are introduced into Cavalcanti and Erosa (2008) [2], a version of Trejos and Wright (1995) [4] with aggregate shocks. Lotteries improve welfare and eliminate the two notable features of the optimum with deterministic trades: over-production and history-dependence. Moreover, the optimum can be supported by buyer take-it-or-leave-it offers. © 2011 Elsevier Inc. All rights reserved. JEL ...

We apply a commodity-money refinement to matching models in which people meet in pairs and buyers make take-it-or-leave-it offers to sellers. The refinement is applied by attaching a utility value to nominal money and letting that value approach zero. An equilibrium satisfies the refinement if it is such a limit. We show that the refinement eliminates a class of non full-support steady states. ...

This note shows that there are monetary equilibria in the model of overlapping generations that are in the core. Some equilibria have positive stocks of outside money in every generation. These equilibria are thus self-enforcing, and introducing money into an economy need not be tantamount to contriving a new social institution designed to enforce sequential contracts.

We add inside and outside money to the standard GEI model. If there enough gains to trade via money, then monetary equilibrium (ME) exists and money has positive value, even when GEI fails to exist. The nonexistence of GEI shows up as a liquidity trap in terms of the ME. In sharp contrast to GEI, the ME are generically determinate not only in terms of real, but also financial, variables. © 2003...

We examine a search money model in which there is a symmetric coincidence of wants in all barter matches. However, when bargaining outcomes are asymmetric across matches, the barter economy is inefficient. Then a robust monetary equilibrium exists provided that money holders enjoy adequate bargaining terms. Fiat money may be welfare improving. In contrast to the literature, it is the asymmetry ...

In this article consumers need money to reduce their transaction costs. We highlight the existence of indeterminacy under a constant money growth within an endogenous growth framework. Real indeterminacy is avoided by an alternative monetary policy such as the interest pegging. The residual price indeterminacy is also ruled out if this monetary policy is completed by a non-Ricardian ...scal pol...

This paper relates predictable gains from positions in fed funds futures contracts to violations of the expectations hypothesis of the term structure of interest rates. Although evidence for predictable gains from positions in short-horizon contracts is mixed, we find that gains in longer-horizon contracts can be well described using Markov switching models, with predictability associated with ...
