We present a model that characterizes the relationship between optimal dynamic cash management and the choice of the means of payment. The novel feature of the model is the sequential nature of the payments choice: in each instant the agent can choose to pay with either cash or credit. This...

We study models where prices respond slowly to shocks because firms are rationally inattentive. Producers must pay a cost to observe the determinants of the current profit maximizing price, and hence observe them infrequently. To generate large real effects of monetary shocks in such a model the...

We consider an inventory model for a liquid asset where the per-period net expenditures have two components: one that is frequent and small and another that is infrequent and large. We give a theoretical characterization of the optimal management of liquid asset as well as of the implied...
