The present paper investigates the impact of German money growth volatility on income … velocity and money demand in view of Friedman's money growth volatility hypothesis. Granger-causality tests provide some …

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...

Money demand in Europe : evidence from the past
Müller-Kademann, Christian; Hahn, Elke - 2000
The conditions under which European monetary policy is likely to be conducted are investigated by means of multi-variate time series modelling using aggregated data of all eleven European Monetary Union member states. A cointegration analysis identifies two stable long-run relationships within a...

Semiparametric diffusion estimation and application to a stock market index
Härdle, Wolfgang; Kleinow, Torsten; Korostelev, … - 2001
The analysis of diffusion processes in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A methodology is proposed for estimating and testing coefficient functions for ergodic diffusions that are not directly observable. It is based on...

A money demand system for M3 in the unified Germany
Lütkepohl, Helmut; Wolters, Jürgen - 1997
A small macroeconomicmodel is constructed starting from a German money demand relation for M3 based on quarterly, seasonally unadjusted data for the period from 1976 to 1996. In contrast to previous studies we build a vector error correction model for M3, GNP, an inflation rate and an interest...

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...

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. This period has been characterized by major structural changes in the Italian financial system and by major changes in monetary policy. This study takes these changes into...

Modeling the interdependence of volatility and inter-transaction duration processes
Grammig, Joachim; Wellner, Marc - 1999
simultaneous estimation of the interdependent duration-volatility model. In an empirical application we utilize the model for an …-transaction duration process and vice versa. In order to solve the estimation problems implied by this interdependent formulation, we first … propose a GMM estimation procedure for the Autoregressive Conditional Duration model. The method is then extended to the …
