We investigate an international monetary business-cycle model in which agents face monetary policy processes that incorporate regime shifts. In any given period agents cannot directly observe the policy regime, but instead form beliefs that are updated via Bayesian learning. As a result, expectation adjustment displays inertia that adds persistence to the e®ects of monetary shocks. Monetary pol...

This paper examines the international experiences with four basic types of monetary policy regimes: 1) exchange-rate targeting, 2) monetary targeting, 3) inflation targeting, and 4) monetary policy with an implicit but not an explicit nominal anchor. The basic theme that emerges from this analysis is that transparency and accountability are crucial to constraining discretionary monetary policy ...

In many countries, the monetary policy instrument sometimes remains unchanged for a long period and shows infrequent responses to exogenous shocks. The purpose of this paper is to provide a new explanation on why the central bank’s policy instrument remains unchanged. In the following analysis, we explore how uncertainty on the private agents’ expectations affects robust optimal monetary policy...

In Kohler (2002) we analyse coalition formation in monetary policy coordination games between n countries. We find that positive spillovers of the coalition formation process and the resulting free-rider problem limit the stable coalition size: since the coalition members are bound by the union’s discipline, an outsider can successfully export inflation without fearing that the insiders will tr...

The conduct of monetary policy in an oil economy with a managed floating exchange rate regime can be challenging in an environment of fiscal dominance and incomplete transition to a market economy. The Five-Year Development Plans provide a natural benchmark against which to assess monetary policy performance in Iran. Price stability has proved elusive, with liquidity growth targets constan...

This study examines the usefulness of the Taylor-rule framework as an organizing device for describing the policy debate and evolution of monetary policy in the United States. Monetary policy during the 1920s and since the 1951 Treasury-Federal Reserve Accord can be broadly interpreted in terms of this framework with rather surprising consistency. In broad terms, during these periods policy has...
