We compute the impulse response to an aggregate monetary shock in a general equilibrium model where firms set prices subject to observation and menu costs. The firm optimally decides when to "review" costly information on the adequacy of its price. Upon each review, the firm chooses whether to...

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 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 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 study the price setting problem of a firm in the presence of both observation and menu costs. In this problem the firm optimally decides when to collect costly information on the adequacy of its price, an activity which we refer to as a price “review”. Upon each review, the firm chooses...

The empirical evidence on rational inattention lags far behind the theoretical developments: micro evidence on the most immediate consequence of observation costs (the infrequent observation of state variables) is not available in standard datasets. We contribute to filling the gap with two...

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 study a model in which prices respond slowly to shocks because firms must pay a fixed cost to observe the determinants of the profit maximizing price, as pioneered by Caballero (1989) and Reis (2006). We extend their analysis to the case of random transitory variation in the firm’s...
