This paper studies the existence of single-price price equilibrium from a given initial distribution of money holdings in a search-theoretic model of money where agents have no time preference. The model is similar to the authors' recent models of search economies with no constraints on money...

This paper presents a model of an economy in which traders use social capital to reduce transaction costs. A key assumption is that there are two types of social capital: “village” capital relies on personal networks and repeat play to guarantee contracts; “market” capital relies on...

This paper is an exercise in applied macroeconomic forecasting. We examine the forecasting power of a vector error-correction model (VECM) that is anchored by a long-run equilibrium relationship between Greek national income and productive public expenditure as suggested by the economic theory....

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

We study the basic economic problem of choice between long-term and short-term commitments under a general characterization of uncertainty (aggregate uncertainty). When contingencies are contractible, a perfect market of Arrow-Debreau contingent claims implements the social optimum. When...
