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...

We document cash management patterns for households that are at odds with the predictions of deterministic inventory models that abstract from precautionary motives. We extend the Baumol-Tobin cash inventory model to a dynamic environment that allows for the possibility of withdrawing cash at...

We present a dynamic cash-management model where agents choose whether to pay with cash or credit at every point in time. In the model credit usage depends on the current stock of cash, a novel result that matches recent micro evidence on household's payment choices. The optimality of such...

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...
