This essay surveys the literature on directed/competitive search, covering theory and applications in, e.g., labor, housing and monetary economics. These models share features with traditional search theory, yet differ in important ways. They share features with general equilibrium theory, but...

We develop a dynamic equilibrium model of asset markets affected by adverse selection. There exists a unique equilibrium where better assets trade at higher prices but in less liquid markets. Sellers of high-quality assets can separate because they are more willing to accept a lower trading...

In this paper, I explore the impact of match-specific heterogeneity at the job creation margin on business cycle fluctuations. I show that this form of heterogeneity alone does not help to amplify labor market volatility, either under full or under asymmetric information. First, I show...

I explore the efficiency properties of a competitive search model with match-specific private information and limited commitment on the workers' side. In a static setting the competitive search equilibrium is constrained efficient, whereas in a dynamic setting it is constrained inefficient...

We extend the concept of competitive search equilibrium to environments with private information, and in particular adverse selection. Principals (e.g. employers or agents who want to buy assets) post contracts, which we model as revelation mechanisms. Agents (e.g. workers, or asset holders)...

This paper constructs a model of non-balanced economic growth. The main economic force is the combination of differences in factor proportions and capital deepening. Capital deepening tends to increase the relative output of the sector with a greater capital share, but simultaneously induces a...
