Empirical evidence on the relationship between technology shocks and e.g. hours worked hinges crucially on the identification of the unobservable technological progress. In this paper, we study different measures of technology in order to find out (i) to what extent they capture the same...

Empirical evidence on the cyclical behavior of technology shocks, or the relative importance of technology shocks versus other structural shocks as sources of fluctuations, hinges crucially on the identification of technological changes. In this paper, we study different measures of technology...

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...

We use micro data on product prices linked to information on the firms that set them to test for selection effects (state dependence) in micro-level producer pricing. In contrast to using synthetic data from a canonical menu-cost model, we find very weak, if any, micro-level selection effects...
