Worldwide monetary and fiscal policies in the past few years have put into sharp relief the fundamental tradeoff between short-run stabilization and long-run sustainability that policymakers face. The paper is organized around this question: How do the effects of routine monetary and fiscal operations designed to achieve macroeconomic stabilization objectives change when the economy moves from ...

We study the monetary instrument problem in a model of optimal discretionary fiscal and monetary policy. The policy problem is cast as a dynamic game between the central bank, the fiscal authority, and the private sector. We show that, as long as there is a conflict of interest between the two policy-makers, the central bank’s monetary instrument choice critically affects the Markov-perfect Nas...

This paper investigate the stabilization bias that arises in a model of non-cooperative monetary and fiscal policy stabilisation of the economy, when monetary authority implements price level targeting but fiscal policy remains benevolent. We demonstrate the gain in welfare improvement depends on the level of steady state debt. If the steady state level of the government debt is low, then the m...

This paper investigates the efficiency of monetary and fiscal policy in a twocountry general equilibrium model with monopolistic competition and wage stickiness. When monopoly distortions are completely eliminated, we find that under some conditions, stochastic government spending can affect the efficiency of global monetary policy rules that replicate the real allocations under flexible wages....

We analyse the impact of interactions between monetary and fiscal policy on macroeconomic stability. We find that in the presence of sovereign default beliefs a monetary policy, which aims to stabilize inflation through an active interest rate policy, will destabilize the economy if the feedback from debt surprises back to the primary surplus is too weak. This result, which relies on endogenous...

Central to ongoing debates over the desirability of monetary unions is a supposed trade-off, outlined by Mundell [1961]: a monetary union reduces transactions costs but renders stabilization policy less effective. If shocks across countries are sufficiently correlated, then, according to this argument, delegating monetary policy to a single central bank is not very costly and a monetary union i...

We characterize monetary and fiscal policy rules to implement optimal responses to a substantial decline in the natural rate of interest, and compare them with policy decisions made by the Japanese central bank and government in 1999—2004. First, we find that the Bank of Japan’s policy commitment to continuing monetary easing until some prespecified conditions are satisfied lacks history depend...
