We present a monetary model in the presence of segmented asset markets that im- plies a persistent fall in interest rates after a once and for all increase in liquidity. The gradual propagation mechanism produced by our model is novel in the literature. We provide an analytical characterization...

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 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...

We extend the Baumol-Tobin cash inventory model to a dynamic environment, which allows for the possibility of withdrawing cash at random times at a low cost. This modification captures developments in withdrawal technology, such as the increasing diffusion of bank branches and ATM terminals. We...

We compute the impulse response of output to an aggregate monetary shock in a general equilibrium when firms set prices subject to a costly observation of the state and a menu cost. We study how the aggregate effects of a monetary shock depend on the relative size of these costs. We find that...

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 tran- sitory variation in the firm’s...

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

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 we find that the size distribution of price changes has a positive excess kurtosis, with a shape...

A monetary union is modelled as a technology that makes surprise devaluations impossible but requires voluntarily participating countries to follow the same monetary policy. It is shown that for low discount factors and sufficiently correlated shocks welfare in the union is higher than that...

It has been argued that the inflationary bias of discretionary monetary policy can be eliminated, and welfare maximized, by the appointment of a central banker who does not care at all about inflation (a 'populist central banker'). We show that this result hinges crucially on the assumption that...
