the model account for relevant properties of the data, but not very significantly. The biggest quantitative potential for search frictions in this setting appears to be in the dynamic implications they generate for inventories and markups in the retail sector. Assessment of this potential is in...

In this paper, we develop a general stochastic model of directed search on the job. Like in the analogous models of random search on the job, the state of the economy in our model includes the infinite-dimensional distribution of workers across different employment states (unemployment, and...

In this paper, we construct a tractable search model of money with a non-degenerate distribution of money holdings. We model search as a directed process in the sense that buyers know the terms of trade before visiting particular sellers, as opposed to undirected search that has dominated the...
