We study the international monetary policy design problem within an optimizing two-country sticky price model, where each country faces a short run tradeoff between output and inflation. The model is sufficiently tractable to solve analytically. We find that in the Nash equilibrium, the policy...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a tractable canonical system in domestic inflation and the output gap. We employ this framework to analyze the macroeconomic implications of three alternative monetary...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyze its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

The unemployment rate in the euro area appears to contain a significant nonstationary component, suggesting that some shocks have permanent effects on that variable. I explore possible sources of this nonstationarity through the lens of a New Keynesian model with unemployment, and assess their...

In this paper we present a simple theory-based measure of the variations in aggregate economic efficiency: the gap between the marginal product of labor and the household's consumption/leisure tradeoff. We show that this indicator corresponds to the inverse of the markup of price over social...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to simple representation in domestic inflation and the output gap. We use the resulting framework to analyze the macroeconomic implications of three alternative...

The present paper describes recent research on two central themes of Keynes' General Theory: (i) the social waste associated with recessions, and (ii) the effectiveness of fiscal policy as a stabilization tool. The paper also discusses some evidence on the extent to which fiscal policy has been...

The present paper revisits a property embedded in most dynamic macroeconomic models: the stationarity of hours worked. First, I argue that, contrary to what is often believed, there are many reasons why hours could be nonstationary in those models, while preserving the property of balanced...
