We construct a search-theoretic model where fiat money coexists with real assets, and all assets can be used as a media of exchange. The terms of trade in bilateral matches are determined by a pairwise Pareto-efficient pricing mechanism. We do not have to appeal to exogenous liquidity...

This paper adopts mechanism design to investigate the coexistence of fiat money and higher-return assets. We consider an economy with pairwise meetings where fiat money and risk-free capital compete as means of payment, as in [28]. The trading mechanism in pairwise meetings is chosen among all...

This paper studies the relationship between the availability of unsecured credit to households and unemployment. We extend the Mortensen-Pissarides model to include a goods market with search and financial frictions. Households, who have limited commitment, face endogenous borrowing constraints...

I apply mechanism design to quantify the cost of inflation that can be attributed to monetary frictions alone. In an environment with pairwise meetings, the money demand that is consistent with an optimal, incentive feasible allocation takes the form of a continuous correspondence that can fit...

This paper develops a model of the public and private provision of liquidity and its relation to unemployment. We extend the Mortensen-Pissarides model of the labor market by adding an over-the-counter (OTC) market. Trades in the OTC market are collateralized with liquid assets, which are...

We develop a two-sector search-matching model of the labor market with imperfect mobility of workers, augmented to incorporate a housing market and a frictional goods market. Homeowners use home equity as collateral to finance idiosyncratic consumption opportunities. A financial innovation that...

We construct a continuous-time, New-Monetarist economy that displays an endogenous, non-degenerate distribution of money holdings. Properties of equilibria are obtained analytically and equilibria are solved in closed form in a variety of cases. Lump-sum transfers financed with money creation...

We study general equilibrium with nonconvexities. In these economies there exist sunspot equilibria without the usual assumptions needed in convex economies, and they have good welfare properties. Moreover, in these equilibria, agents act as if they have quasi-linear utility. Hence wealth...

This paper investigates the welfare and output effects of inflation in a monetary economy with search frictions and sticky prices. Agents trade in both a centralized Walrasian market and a decentralized search market. Trade has two dimensions: the frequency of trades (how often agents trade) and...
