Diese Studie untersucht die formale Aussage, dass in kleinen offenen Volkswirtschaften flexible Wechselkurse eine 'sckockabsorbierende Wirkung' entfalten und exogene Störungen effektiver als feste Wechselkurse mildern. Ein intertemporales Modell mit nominalen Rigiditäten zeigt die...

This paper is about contagion and interdependence among Central European economies. It investigates the extent to which country-specific shocks spread across these countries beyond the normal channels of interdependence, taking into account common external shocks. To model such shocks, we make...

This paper shows that properly designed interest rate rules can be consistent withmaintaining exchange rate stability. It sheds light on the relation between interest rate rules,exchange rate regimes, and determinacy of the rational expectation equilibrium in a modernmacroeconomic framework.[...]

This paper addresses the consumption–real exchange rate anomaly.International real business cycle models based on complete financialmarkets predict a unitary correlation between the realexchange rate and the ratio of home to foreign consumptionwhen subjected to supply-side shocks. In the data,...

This paper demonstrates effects of economic convergence processes on the foreign exchange behaviour in a monetary modelling approach. Since the exchange rate represents the relative price of two currencies, commonness of stochastic trends between the fundamental determinants of supply and demand...

Fundamentals may determine the range of real exchange rate fluctuation, through signalsof misalignment, even if they are not a major influence on the level within that range.This can explain the puzzle that more open economies experience lower real exchangerate volatility...

Since changes in import prices feed into consumer prices and thus might affect monetary policydecisions, policymakers need to establish whether or not German importers’ long-run pricingbehaviour has changed. Of particular interest are any shifts in the importance of cost passthroughand...

Explaining exchange rates has long been an important but vexing issue in international economics and finance. In recent years, a number of studies have shown that investors' private information plays a central role in determining exchange rates. We demonstrate in this paper that the private...

While it is widely agreed that Purchasing Power Parity (PPP) holds as a long-runconcept the specific dynamic driving the process is largely build upon a priori economicbelief rather than a thorough statistical modeling procedure. The two prevailing timeseries models, i.e. the exponential smooth...

We consider a simple random walk process, a special case ofthe Martingale model, which exhibits a deterministic break in its drift term,for instance, from positive to negative. This particular example can be aplausible model for a time series on exchange rates which displays a persistentcurrency...
