In practice, central banks have been confronted with a trade-off between stabilising inflation and output when dealing with rising oil prices. This contrasts with the result in the standard New Keynesian model that ensuring complete price stability is the optimal thing to do, even when an oil...

While consumption habits have been utilised as a means of generating a hump shapedoutput response to monetary policy shocks in sticky-price New Keynesian economies,there is relatively little analysis of the impact of habits (particularly, external habits) onoptimal policy. In this paper we...

Caplin & Leahy (1996) show that, when central bankers learn about theeconomy by observing its response to policy shock, cautious monetary policymay be ineffectual as private agents correctly anticipate that today's interestrate cuts are likely to be followed by future cuts. The central banker...

Recent theoretical work shows that changes in the volatility of inflation and/or unem-ployment affect equilibrium in°ation outcomes when the central banker's loss functionis asymmetric. We show that previous evidence offered in support of the propositionthat the volatility of unemployment helps...

The Friedman rule, a widely studied prescription for monetary policy, is optimal inTownsend’s turnpike model of money; it is not so in the overlapping generations versionof his stochastic relocation model of money. We investigate these monetary models inthe light of this disparity. To that...

In this paper, we explore the connection between optimal monetary policy and heterogeneityamong agents. We study a standard monetary economy with two types of agents inwhich the stationary distribution of money holdings is non-degenerate. Sans type-specific fiscalpolicy, we show that the...

Inflation rates in a number of OECD follow a common trend over the past four decades: inflation starts out low in the 1960s, rises for a time before peaking in the 1970s or early 1980s, and then falls back to initial levels. This similarity in the behavior of trend inflation suggests that any...

In models of money with an infinitely-lived representative agent (ILRA models), the optimal monetary policyis almost always the Friedman rule. Overlapping generations (OG) models are different: in this paper, westudy how they are different, and why. We investigate the welfare properties of...
