In a general equilibrium model with incomplete asset markets, nominal securities, and mean-variance preferences, a monetary union is desirable when the gain from eliminating excess volatility of nominal variables exceeds the cost of reducing the number of currencies with which to hedge risks....

This paper studies the relation between seigniorage and inflation in Argentina for the period 1979-1989. We estimate a money demand function and derive the Laffer curve for several sub-periods with different monetary/exchange rate regimes. We find that for most of the period the Argentine...

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 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...

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...
