This paper compares the welfare costs of business cycles in a dollarized economy to those arising in economies in which monetary policy takes the form of inflation targeting, money growth rate pegs, or devaluation rate rules. The analysis is conducted within an optimizing model of a small open...

Using panel structural VAR analysis and quarterly data from four industrialized countries, we document that an increase in government purchases leads to an expansion in output and private consumption, a deterioration in the trade balance, and a depreciation of the real exchange rate (i.e., a...

A number of empirical studies document that marginal cost shocks are not fully passed through to prices at the firm level and that prices are substantially less volatile than costs. We show that in the relative-deep-habits model of Ravn, Schmitt-Grohe, and Uribe (2006), firm-specific marginal...

In this paper we study optimal fiscal and monetary rules in a medium-scale estimated model of the U.S. business cycle. The model features several real and nominal rigidities that have been identfied in the recent literature as salient in explaining observed aggregate fluctuations. The government...

This paper studies optimal fiscal and monetary policy under sticky product prices. The theoretical framework is a stochastic production economy without capital. The government finances an exogenous stream of purchases by levying distortionary income taxes, printing money, and issuing one-period...

This paper analyzes the implications of a balanced budget fiscal policy rule for the determinacy of the price level in a cash-in-advance economy under three alternative monetary policy regimes. It shows that, in such stylized models with flexible prices and a period-by-period balanced budget...

This paper proposes a novel international transmission mechanism based on the assumption of deep habits. The term deep habits stands for a preference specification according to which consumers form habits on a good-by-good basis. Under deep habits, firms face more elastic demand functions in...
