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 document the presence of both small and large price changes in individual price records from the CPI in France and the US. After correcting for measurement error and cross-section heterogeneity, the size-distribution of price changes has a positive excess kurtosis. We propose an analytical...

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 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 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 present new evidence on the presence of both small and large price changes in individual price records from the CPI both in France and in the US. After correcting for measurement error and cross-section heterogeneity we find that the size distribution of price changes has a positive excess...

We model the decisions of a multi-product firm that faces a fixed “menu” cost; once it is paid, the firm can adjust the price of all its products. We characterize analytically the steady state firm’s decisions in terms of the structural parameters: the variability of the flexible prices,...

We study the stylized problem of a multi-product firm that can revise prices only after paying a fixed “menu” cost. The key assumption, introduced by Lach and Tsiddon (1996, 2007) and Midrigan (2007, 2009), is that once the menu cost is paid the firm can adjust the price of all its products....
