Continuos credibility effects are incorporated into a simple model of optimal monetary policy. The resulting model provides explanations for a number of "folk theorems" about credibility in monetary policy. A central bank with low initial credibility pursues a more restrictive policy than a...

In an attempt to move beyond the purchasing power parity hypothesis, this paper studies two issues. First, the causes of movements of real exchange rates are investigated. In contrast to the typical result, supply shocks are found to dominate the long-run variance decompositions for all...

Previous studies of the sources of real exchange rate fluctuations have concluded that real demand shocks account for the bulk of the movements in real exchange rates. In this paper, bilateral real exchange rates between the US, the UK, Germany and Japan are investigated using a statistical...

The co-movements of nominal exchange rates and short-term interest rates as the economy is hit by shocks is a potential source of ex post deviations from uncovered interest rate parity. This paper investigates whether an established model of endogenous monetary policy in an open economy is...

A widely spread belief among economists is that monetary policy has relatively short-lived effects on real variables such as unemployment. Previous studies indicate that monetary policy affects the output gap only at business cycle frequencies, but the effects on unemployment may well be more...

The strong response of long-term interest rates to macroeconomic shocks has typically been explained in terms of informational asymmetries between the central bank and private agents. The standard models assume that the equilibrium real interest rate is constant over time and independent of...

Data on short investments in Swedish long-term bonds as the bonds mature contains unusually rich information about the relationship between duration and the first and second moments of bond returns. We identify three different channels through which duration affects bond returns. The liquidity...
