In den entwickelten Volkswirtschaften ist das Produktivitätswachstum seit den 1970er Jahren tendenziell gesunken, zeigen die Statistiken–eine Beobachtung, die angesichts der weitreichenden Digitalisierung der Wirtschaft erstaunt. Sie könnte auf Messfehlern beruhen, ist sie aber realistisch,...

This paper disentangles direct spillovers and common factors, the sources of correlations in simultaneous heteroscedastic systems. While these different components are not identifiable by standard means without restrictions, it is shown that they can be distinguished by specifying the variances...

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...

The Expectations Hypothesis of the Term Structure (EHT) implies cointegration between interest rates of different maturities and predicts certain values for adjustment speed. We estimate reduced-form Vector Error Correction Models (VECMs) of the US term structure. These are derived from a...

The present work deals with a frequently detected failure of the uncovered interest rate parity (UIP) - the absence of bivariate cointegration between domestic and foreign interest rates. We explain the non-stationarity of the interest differential via central bank reactions to exchange rate...

The present paper sheds further light on a well-known (alleged) violation of the expectations hypothesis of the term structure (EHT): the frequent finding of unit roots in interest rate spreads. We show that the EHT implies (i) that the nonstationarity stems from the holding premium, which is...
