This paper characterizes jointly optimal default and exchange-rate policy. The theoretical environment is a small open economy with downward nominal wage rigidity as in Schmitt-Grohe and Uribe (2013) and limited enforcement of international debt contracts as in Eaton and Gersovitz (1981). It is...

When the Central Bank sets nominal rates as a a non-decreasing function of the inflation rate to stabilize the economy, that is it uses a Taylor Rule, the zero lower bound on interest rates may result in multiple equilibria and a liquidity trap. However, if fiscal policy is non-Ricardian, or...

The combination of a fixed exchange rate and downward nominal wage rigidity creates a real rigidity. In turn, this real rigidity makes the economy prone to involuntary unemployment during external crises. This paper presents a graphical analysis of alternative policy strategies aimed at...

Each of these driving forces is buffeted by four types of structural innovations: unanticipated innovations and innovations anticipated one, two, and three quarters in advance. We find that anticipated shocks account for more than two thirds of predicted aggregate fluctuations. We estimate that...

This paper identifies a new source of business-cycle fluctuations. Namely, a common stochastic trend in neutral and investment-specific productivity. We document that in U.S. postwar quarterly data total factor productivity (TFP) and the relative price of investment are cointegrated. We show...

A traditional argument against a balanced-budget fiscal policy rule is that it amplifies business cycles by stimulating aggregate demand during booms via tax cuts and higher public expenditures and by reducing demand during recessions through a corresponding fiscal contraction. This paper...

This paper characterizes conditions under which interest-rate feedback rules that set the nominal interest rate as an increasing function of the inflation rate induce aggregate instability by generating multiple equilibria. It shows that these conditions depend not only on the monetary-fiscal...

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...

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...
