This paper studies how different search protocols affect social welfare in a search market with scarcity. Agents search for objects that differ in quality either through a random or a directed search protocol. Random search protocol, in which agents are randomly paired to an object of any...

We examine wage competition in a model where identical workers choose the number of jobs to apply for and identical firms simultaneously post a wage. The Nash equilibrium of this game exhibits the following properties: (i) an equilibrium where workers apply for just one job exhibits unemployment...

I study social learning in networks with information acquisition and choice. Bayesian agents act in sequence, observe the choices of their connections, and acquire information via sequential search. Complete learning occurs if search costs are not bounded away from zero and the network is...

Classic models of fire-sales that emphasize liquidity-constrained natural buyers can-notfully account for the asset fire-sales during the Financial Crisis of 2008. I present a modelto demonstrate that fire-sales may happen even when there is a sizable pool of naturalbuyers and in the absence of...

It is challenging to explain the collapse in the price of subprime mortgage-backed securities (MBS) during the Financial Crisis of 2008, using the existing models of fire-sale. I present amodel to demonstrate that fire-sales may happen evenwhen there is a relatively sizable pool of natural...

We investigate an equilibrium search model in which the search frictions are increasing with the distance to the central business district allowing for on-the-job search and endogenous (monopsony) wage formation and land allocation. We find that there are many different possible outcomes with...

The effects of households' indebtedness on their house-selling decisions are studied in a dynamic equilibrium model with search in the housing market and defaultable long-term mortgages. In equilibrium, both sellers' asking prices and time-to-sell increase with the relative size of their...

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode by which an intermediary holds inventories...

A model of the distribution of home-ownership in a city is developed. Heterogeneous houses are built by a competitive development industry and either rented competitively or sold through directed search to households which differ in wealth and sort over housing types. In the absence of both...
