A prominent feature of the Kiyotaki and Wright (1989) model of commodity money is the multiplicity of dynamic equilibria. We show that the frequency of search is strongly related to the extent of multiplicity. To isolate the role of frequency of search in generating multiplicity, we (i) vary the...

This paper pursues a line of Cass and Shell, who advocate monetary models that are genuinely dynamic and fundamentally disaggregative and incorporate diversity among households and variety among commodities. Recent search-theoretic models fit this description. We show that, like overlapping...

This paper estimates a medium-scale DSGE model with search unemployment by matching model and data spectra. Price mark-up shocks emerge as the main source of business-cycle fluctuations in the euro area. Key factors in the propagation of these disturbances are a high degree of inflation...
