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...

Currency substitution and the stability of the Italian demand for money before the entry into the monetary union, 1972 - 1998

Nielsen, Hannah; Tullio, Giuseppe; Wolters, Jürgen - 2000

A money demand function for M2 is estimated for Italy for the period 1972-1998 within an error correction framework … monetary policy. This study takes these changes into account. Moreover, currency substitution, especially between Italy and … Germany is incorporated into the model. By accounting for structural breaks and currency substitution a stable money demand …

Fractional integration and the dynamics of UK unemployment

Gil-Alaña, Luis A.; Henry, S. G. B. - 2000

This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

A fractionally integrated model with a mean shift for the US and the UK real oil prices

Gil-Alaña, Luis A. - 2000

In this article we model the log of the U.S. and the U.K. real oil prices in terms of fractionally integrated processes with a mean shift. We use different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicate that if we model the...

A fractionally integrated exponential model for UK unemployment

Gil-Alaña, Luis A. - 2000

Fractionally integrated models with the disturbances following a Bloomfield (1973) exponential spectral model are proposed in this article for modelling the U.K. unemployment. This enables us a better understanding of the low-frequency dynamics affecting the series, without relying on any...

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...

Nonlinear error correction and the efficient market hypothesis : the case of German dual-class shares

Breitung, Jörg; Wulff, Christian - 1999

The efficient market hypothesis implies that asset prices cannot be cointegrated. On the other hand, arbitrage processes prevent prices of fundamentally related assets from drifting far away. An attractive model that reconciles these two conflicting facts is the nonlinear error correction...

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...

Sources of German unemployment : a structural vector error correction analysis

Brüggemann, Ralf - 2001

parameter restrictions. A cointegration analysis for the unified Germany reveals a long rum relationship between real wages …. We compare these results to results from a standard SVECM and find that, using the Subset VECM reduces estimation … uncertainty. In contrast to previous studies for West Germany, we find that, unemployment is equally determined by technology …

Money and prices : an I(2) analysis for the euro area

Holtemöller, Oliver - 2002

The concept of integrated stochastic processes is widely used in empirical macroeconomics; and cointegration analysis is an important framework to analyze economic time series both in single equation and in system approaches. This framework is not only suited to study the relationships between...
