Recently, the search-theoretic approach to monetary economics has been generalized to incorporate bilateral bargaining theory in order to determine the purchasing power of money endogenously (the first-generation of models in this literature essentially assume that prices are fixed exogenously)....

The effects of money (anticipated inflation) on capital formation is a classic issue in macroeconomics. Previous papers adopt reduced-form approaches, putting money in the utility function, or imposing cash in advance, but using otherwise frictionless models. We follow instead a literature that...

When labor is indivisible, there exist efficient outcomes with some agents randomly unemployed (Rogerson 1988). We integrate this idea into the modern theory of monetary exchange, where some trade occurs in centralized markets and some in decentralized markets (as in Lagos and Wright 2006). This...

We extend the notion of competitive search equilibrium to an environment with adverse selection. Uninformed principals post contracts to attract informed agents. Agents observe the contracts and apply for one, trading off the probability of matching with a principal against the terms of trade...

The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them...

Why do some sellers set nominal prices that apparently do not respond to changes in the aggregate price level? In many models, prices are sticky by assumption; here it is a result. We use search theory, with two consequences: prices are set in dollars, since money is the medium of exchange; and...

We study models of credit with limited commitment, which implies endogenous borrowing constraints. We show that there are multiple stationary equilibria, as well as nonstationary equilibria, including some that display deterministic cyclic and chaotic dynamics. There are also stochastic...
