Die Analyse von täglichen Änderungen der deutschen Umlaufsrendite für festverzinsliche Wertpapiere der öffentlichen Hand zeigt starke Evidenz für eine zeitliche Abhängigkeit in den Varianzen für die Periode Januar 1981 - Juli 1996. Der untersuchte Zeitraum umfasst die Einführung von...

In this paper we test the purchasing power parity for the post Bretton Woods period for 18 main industrial countries. As base currencies we use alternatively the Deutsche mark, the Japanese yen, and the US dollar. We employ error correction models for single countries and on the level of pooled...

We analyze daily changes of two log foreign exchange (FX) rates involving the Deutsche Mark (DEM) for the period 1975 - 1998, namely FX-rates measured against the US dollar (USD) and the Japanese yen (JPY). Ta account for volatility e1ustering we fit a GARCH(l,l)-model with leptokurtic...

Regarding inflation as being a monetary phenomenon in the long-run is a widely-held view in modern macro economics. We analyse this topic by means of a P-star model. Based on the quantity theory of money, this approach explains inflation via a supposed equilibrium price level (P-star), which...

In this paper we follow an empirical approach to examine the implications of the Fisher hypothesis, namely cointegration linking interest rates and inflation, and stationarity of the real interest rate implying in turn homogeneity of the potential equilibrium relation. The considered sample is...

In this paper we follow an empirical approach to examine the implications of the Fisher hypothesis, namely cointegration linking interest rates and in°ation, and stationarity of the real interest rate implying in turn homogeneity of the potential equilibrium relation. The considered sample is...

Investigating the German money demand function the paper provides a vector autoregressive model that allows for cointegration at the zero frequency and at the seasonal frequencies. The sample period is 1975:1 to 1995:4 and thus contains the German unification period. Using prediction tests the...
