Fengler, Matthias R.; Herwartz, Helmut - 2001

Multivariate Volatility Models belong to the class of nonlinear models for financial data. Here we want to focus on multivariate GARCH models. These models assume that the variance of the innovation distribution follows a time dependent process conditional on information which is generated by...

Was there a regime change in the German monetary transmission mechanism in 1983?

Candelon, Bertrand; Lütkepohl, Helmut - 2000

Recent investigations of the transmission mechanism of German monetary policy arrive at quite different conclusions regarding its stability during the period of monetary targeting by the Bundesbank. In this study small dynamic models for the monetary sector of the German economy are analyzed in...

The response of long-term interest rates to news about monetary policy actions : empirical evidence for the US and Germany

Nautz, Dieter; Wolters, Jürgen - 1998

We reexamine the expectations theory of the term structure focusing on the question how monetary policy actions … tests of expectations theory this implication only requires rational expectations but not stationary risk premia. Therefore …, its empirical test sheds new light on the importance of expectations theory for the determinants of the term structure of …

The transmission of German monetary policy in the pre-Euro period

Lütkepohl, Helmut; Wolters, Jürgen - 2001

A small macroeconomic model is constructed to study the transmission of the monetary policy conducted by the Deutsche Bundesbank (DBB) since the middle of the 1970s. For this purpose quarterly, seasonally unadjusted data for the period from 1975 to 1998 are used, that is, the period until the...

Empirical modeling of the DEM/USD and DEM/JPY foreign exchange rate: Structural shifts in GARCH-models and their implications

Herwartz, Helmut; Reimers, Hans-Eggert - 2001

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...

Comparison of bootstrap confidence intervals for impulse responses of German monetary systems

Benkwitz, Alexander; Lütkepohl, Helmut; Wolters, Jürgen - 1999

It is argued that standard impulse response analysis based on vector autoregressive models has a number of shortcomings. Although the impulse responses are estimated quantities, measures for sampling variability such as confidence intervals are often not provided. If confidence intervals are...

Fractional cointegration and real exchange rates

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

This paper uses fractional integration and cointegration in order to model the DM/dollar and the yen/dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be...
