This paper proposes a utility function incorporating both habit formation and an endogenous rate of time preference in a manner consistent with the intuition of Irving Fisher regarding the influence of past consumption on impatience. It is shown that the ne w specification is tractable and...

Using directed search to model the product market and the labor market, I show that large plants can pay higher wages to homogeneous workers and earn higher expected profit per worker than small plants, although plants are identical except size. A large plant charges a higher price for its...

We integrate a monetary search model into open-economy macro to analyze the gains from coordinating on inflation. Search frictions and local congestion lead to a determinate exchange rate between two currencies. Relative prices deviate from the law of one price. Because the deviations depend on...

We analyze bureaucracy and corruption in a market with decentralized exchange and "lemons." Exchange is modeled as a sequence of bilateral, random matches. Agents have private information about the quality of goods they produce and can supplement trade with socially inefficient bribes....

We model a labor market where employed workers search on the job and firms direct workers' search using wage offers and employment probabilities. Applicants observe all offers and face a trade-off between wage and employment probability. There is wage dispersion among workers, even though all...

In this article, I integrate the microfoundation of monetary theory with the model of limited participation to analyze the competition between nominal bonds and money. The market for government nominal bonds is centralized and Walrasian, whereas the goods market is modeled as random matches. The...

This paper examines the dynamic effects of distortionary taxes in a small open economy. The employed utility function implies both endogenous rates of time preference and a tractable form of weak nonseparability between consumption and leisure. Weak nonseparability induces novel long-run welfare...
