We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables and unobservable "modes." The form of model uncertainty our framework...

The trade-off between interest rate variability and the width of an exchange rate target zone is examined, using the regulated Brownian motion model of target zones. It is shown that for narrow exchange rate bands, and for reasonable parameter values, the interest rate differential's asymptotic...

The foreign exchange risk premium in an exchange rate target-zone regime with devaluation/realignment risks is derived. In contrast to previous literature, the exchange rate's heteroscedasticity within the band, as well as a separate devaluation/realignment risk, is taken into account. The risk...

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 inflationary policy than a high-credibility bank,...

We show how to construct optimal policy projections in Ramses, the Riksbank's open-economy medium-sized DSGE model for forecasting and policy analysis. Bayesian estimation of the parameters of the model indicates that they are relatively invariant to alternative policy assumptions and supports...

Under the assumption of no arbitrage, exchange rate target-zone credibility is tested by whether domestic interest rates fall within `rate-of-return bands' between the maximum and minimum home-currency rate of return on a foreign investment in the absence of a devaluation. Under the assumption...
