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 analyzes monetary exchange in a search model allowing for multilateral matches to be formed, according to a standard urn-ball process. We consider three physical environments: indivisible goods and money, divisible goods and indivisible money, and divisible goods and money. We compare...

Inflation, Employment and Interest Rates in an Economy with Endogenous Market Segmentation Aubhik Khan, Federal Reserve Bank of Philadelphia Julia K. Thomas, University of Minnesota We examine a monetary economy where households incur fixed transactions costs when exchanging bonds and money and,...

A settlement system is a set of rules and procedures that govern when and how funds are transferred between banks. Perhaps the most crucial feature of a settlement system is the frequency with which settlement occurs. On the one hand, a higher frequency of settlement limits the risk of default...

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...

This paper is part of the growing literature that uses micro-data to distinguish among alternative price behavior models and provide some measurements essential for calibration exercises. We use weekly grocery US scanner data and attempt to distinguish among three types of models: State...

What instruments of monetary policy must be used in order to implement a unique equilibrium? This paper revisits the issues addressed by Poole (1970) and Sargent and Wallace (1975) on the multiplicity of equilibria when policy is conducted with either interest rate or money supply rules. We show...

Should monetary policy be cyclical? The debate around this question is old but has benefited very little from research on the pure theory of money. In our model, people trade in pairs, without double coincidence of wants and face seasonal fluctuations. Monetary policy is restricted to taxing...

Monetary search models are difficult to analyze unless the distribution of money holdings is made degenerate. Popular techniques include using an infinitely large household (Shi 1997) and adding a centralized market with quasi-linear utility (Lagos and Wright 2005). Wallace (2002) suggests as an...

We study markets where innovators can sell ideas to entrepreneurs, who may be better at implementing them. These markets are decentralized, with random matching and bargaining. Entrepreneurs hold liquid assets lest potentially profitable opportunities may be lost. We extend existing models of...
