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...

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...

In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations. Moreover, the properties of the tests...

This paper explores the long run relationship between public and private investment in the euro area in terms of capital stocks and gross investment flows. Panel techniques accounting for international spillovers are employed. While private and public capital stocks are cointegrated, the...
