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...

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...

We analyse the relationship between the debt to GDP ratio and real per capita GDP growth for the euro area members by distinguishing between periods of sustainable and non-sustainable debt. Thresholds are theory-based and depend on the macroeconomic framework. If the interest rate exceeds...

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...

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 ac-counting for international spillovers are employed. While private and public capital stocks are cointegrated, the...

Generally speaking, money demand models represent a natural benchmark against which monetary developments can be assessed. In particular, the existence of a well-specified and stable relationship between money and prices can be perceived as a prerequisite for the use of monetary aggregates in...

We investigate hysteresis and persistence behaviour in the course of unemployment in EU countries and US states by means of first and second generation panel unit root tests. While the former tests assume independent cross sections, the latter control for dependencies. The first generation tests...

We explore the long and short run relationship between private consumption, disposable income and housing and financial wealth approximated by price indices for a panel of industrialized countries. Consumption, income and wealth are cointegrated in their common, but not in their idiosyncratic...
