We investigate the efficiency property of a monetary economy with spot trade. We prove a conjecture that is essentially due to Bewley ("Models of Monetary Economics" (1980); "Econometrica" 51 (1983), 1485-504). The gist is that monetary spot trading is nearly efficient ex ante in an environment...

This article investigates the characteristics of stationary single-price equilibrium in a monetary random-matching model where agents can hold an arbitrary amount of divisible money and where production is costly. At such an equilibrium, agents' money holdings are endogenously determined and...

We construct a model of the credit market where financial contracting is subject to costly state verification and moral hazard. The economy's aggregate activity and its equilibrium lending mechanism are determined jointly. We analyze how changes in the model's exogenous variables, including the...

Recent versions of pairwise random matching models of money with divisible and perishable goods are amended to allow individuals to hold more than one unit of an indivisible asset. The asset resembles a fiat asset, except that nominal holdings of it yield a small amount of utility. There is a...

I argue that monetary economics should be pursued by applying implementation theory to models which contain explicit frictions that make money essential. The argument has two parts. First, I argue that models in which real balances are assumed to be productive--models with money in utility or...

An earlier analysis of Cavalcanti and Wallace showing that the set of allocations achievable using outside (government) money is a subset of those achievable using inside (private) money is extended. Here, the class of outside-money allocations is enriched by allowing the planner to make...

According to <link rid="b26">Pareto (1896)</link>, the distribution of income depends on "the nature of the people comprising a society, on the organization of the latter, and, also, in part, on chance." In the model developed here the "nature of the people" is captured by attitudes toward marriage, divorce,...

In 1900 only 6% of unwed teenage females engaged in premarital sex. Now, three quarters do. The sexual revolution is studied here using an equilibrium matching model, where the costs of premarital sex fall over time due to technological improvement in contraceptives. Individuals differ in their...
