If floating exchange rates stabilize shocks rather than create shocks, a country that joins a monetary union or fixes its exchange rate looses a stabilizing mechanism. We use a first difference structural VAR on trade weighted macroeconomic data to study the role of floating exchange rates for...

We show that empirical results concerning the behavior of floating exchange rates differ between otherwise identical cointegrated and non-cointegrated VAR models. In particular, virtually all ten-year movements in nominal exchange rates are due to fundamental supply and demand shocks when long...

This paper uses a dynamic stochastic rational expectations model of a small open economy to shed some light on factors determining exits from a fixed to a flexible exchange rate regime. Exits are in the model determined by a concern for macroeconomic stabilization. If cost-push shocks are...

This paper takes a critical look at available proxies of uncertainty. Two questions are adressed: (i) How do we evaluate proxies given that subjective uncertainty is inherently unobservable? (ii) Is there such a thing as a general macroeconomic uncertainty? Using correlations, some narrative...

This paper sets up a simple model for interventions and interest rate setting assuming that the policy maker cares about deviations in inflation from a target level. Under a quadratic cost of interest rate adjustments and interventions the policy maker should use a combination of interest rate...
