We propose an integrated treatment of the problems of optimal monetary and fiscal policy, for an economy in which prices are sticky and the only available sources of government revenue are distorting taxes. Our linear-quadratic approach allows us to nest both conventional analyses of optimal...

Erceg et al. (2000) show that when both wages and prices are sticky, maximization of expected utility is equivalent to minimizing a loss function with three terms, involving measures of the variability of wage inflation, price inflation and the output gap respectively. Here we generalize their...

This paper considers the appropriate stabilization objectives for monetary policy in a microfounded model with staggered price-setting. Rotemberg and Woodford (1997) and Woodford (2002) have shown that under certain conditions, a local approximation to the expected utility of the representative...

We consider a general class of nonlinear optimal policy problems involving forward-looking constraints (such as the Euler equations that are typically present as structural equations in DSGE models), and show that it is possible, under regularity conditions that are straightforward to check, to...

Standard discussions of flexible inflation targeting as an optimal monetary policy abstract completely from the consequences of monetary policy for the government budget. But at least some of the countries now adopting inflation targeting have substantial difficulty in controlling fiscal...

We reconsider the optimal taxation of income from labor and capital in the stochastic growth model analyzed by Chari et al. (1994, 1995), but using a linear-quadratic (LQ) approximation to derive a log-linear approximation to the optimal policy rules. The example illustrates how inaccurate...

Deleveraging from high debt can provoke deep recession with significant international side effects. The exchange rate of the deleveraging country will depreciate in the short run and appreciate in the long run. The real interest rate will fall by more than in the rest of the world. Bounds and...

This paper studies optimal monetary policy under dynamic debt deleveraging once the zero bound is binding. Unlike the existing literature, the natural rate of interest is endogenous and depends on macroeconomic policy. Optimal monetary policy successfully raises the natural rate of interest by...

This paper proposes an explanation of the international home bias in equity based on ambiguity aversion. Doubts imply an additional hedging motif driven by the interaction between real exchange rate risk and ambiguity aversion. What matters is the long-run as opposed to the short-run risk....

Recent studies have emphasized the role of valuation effects due to exchange rate movements in easing the process of adjustment of the external balance of a country. This paper asks to what extent valuation effects are desirable from a global perspective as a mean to achieve an efficient...
