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...

The main purpose of this paper is to investigate the West-German consumption process depending on wealth and income with seasonal cointegration techniques using the framework of vector autoregressive models to capture the seasonal pattern of the series. The vector autoregressive models are 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...

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...

Benchmark revisions in non-stationary real-time data may adversely affect the results of regular revision analysis and the estimates of long-run economic relationships. Cointegration analysis can reveal the nature of vintage heterogeneity and guide the adjustment of real-time data for benchmark...

We analyse the relationship between the debt-to-GDP ratio and real per capita GDP growth for euro area members and a broader set of industrial countries by distinguishing periods of sustainable and non-sustainable debt. Thresholds for debt are theory-driven and depend on-macroeconomic...

This paper models the relationship between consumer and asset prices (approximated by house prices, oil prices and the exchange rate) by means of a Markov Switching model (MS model). It can be shown that house prices appear to play a significant role in the determination of consumer prices in a...
