This paper discusses how price stability can be defined and how price stability can be maintained in practice. Some lessons for the Eurosystem are also considered. With regard to defining price stability, the choice between price-level stability and low (including zero) inflation and the...

We identify an inflationary technology news shock as the leading source of business cycle variations for the postwar U.S. economy. This shock acts like a demand shock: it induces strong positive comovement in real quantities - GDP, consumption, investment - and weak positive comovement between...

Why do countries tend to repay their domestic and external debt, even though the legal enforcement of the sovereign debt contract is limited? Contrary to conventional wisdom, we argue that temporary market exclusion after default is costly. When the domestic financial market is characterized by...

This paper specifies a new convenient algorithm to construct policy projections conditional on alternative anticipated policy-rate paths in linearized dynamic stochastic general equilibrium (DSGE) models, such as Ramses, the Riksbank's main DSGE model. Such projections with anticipated...

The purpose of the paper is to survey and discuss in ation targeting in the context of monetary policy rules. The paper provides a general conceptual discussion of monetary policy rules, attempts to clarify the essential characteristics of in ation targeting, compares in ation targeting to other...

The paper extends previous analysis of closed-economy inflation targeting to a small open economy with forward-looking aggregate supply and demand with some microfoundations, and with stylized realistic lags in the different transmission channels for monetary policy. The paper compares targeting...

We define and study transparency, credibility, and reputation in a model where the central bank's characteristics are unobservable to the private sector and are inferred from the policy outcome. A low-credibility bank optimally conducts a more expansionary policy than a high-credibility bank, in...

Policy rules that are consistent with inflation targeting are examined in a small macro-econometric model of the US economy. We compare the properties and outcomes of explicit "instrument rules" as well as "targeting rules". The latter, which imply implicit instrument rules, may be closer to...
