This paper computes welfare-maximizing monetary and fiscal policy rules in a real business cycle model augmented with sticky prices, a demand for money, taxation, and stochastic government consumption. We consider simple feedback rules whereby the nominal interest rate is set as a function of...

This essay aims to explain the nature of monetary and fiscal policy interactions and how those interactions could inform the fiscal rules that countries choose to follow. It makes two points: (1) monetary policy control of inflation requires appropriate fiscal backing; (2) European fiscal...

The goal of this paper is to compute optimal monetary and fiscal policy rules in a real business cycle model augmented with sticky prices, a demand for money, taxation, and stochastic government consumption. We consider simple policy rules whereby the nominal interest rate is set as a function...

The paper examines international issues that arise in the design and evaluation of macroeconomic policy rules. It begins with a theoretical investigation of the effects of fiscal and monetary policy in a two-country rational expectations model with staggered wage and price setting and with...

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...

This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time-inconsistent preferences with a present-bias towards public spending. The government chooses a fiscal rule to trade off its desire to commit to not overspend...

Recurrent concerns over debt sustainability in emerging and developed nations have prompted renewed debate on the role of fiscal rules. Their optimality, however, remains unclear. We provide a quantitative analysis of fiscal rules in a standard model of sovereign debt accumulation and default...

Governments are present-biased toward spending. Fiscal rules are deficit limits that trade off commitment to not overspend and flexibility to react to shocks. We compare coordinated rules – chosen jointly by a group of countries – to uncoordinated rules. If governments' present bias is...

In analyses of "liquidity trap" problems associated with the zero lower bound (ZLB) on nominal interest rates, it is important to emphasize the difference between policy rule changes, intended to help escape an existing ZLB situation, and maintained policy rules designed so as to avoid ZLB...

I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter,...
