We apply Diebold-Yilmaz spillover index methodology to monthly industrial production indices to study business cycle interdependence among G-6 industrialized countries since 1958. The business cycle spillover index fluctuates substantially over time, increasing especially after the 1973-75,...

Time-series regressions including non-linear transformations of an integrated variable are not uncommon in various fields of economics. In particular, within the Environmental Kuznets Curve (EKC) literature, where the effect on the environment of income levels is investigated, it is standard...

We apply Purchasing Power Parity (PPP) theory to the analysis of long- run equilibrium in the foreign exchange market. We study the case of Portugal vis-à-vis Germany and Spain, and the case of Spain vis-à-vis Germany, in the period 1960-1990. The empirical analysis was based on unit-root...

We analyze the issue of the impact of multiple breaks on monetary neutrality results, using a long annual international data set. We empirically verify whether neutrality propositions remain addressable (and if so, whether they hold or not), when unit root tests are carried out allowing for...

In this paper we aim at testing the inflation persistence hypothesis as well as modelling (using logistic smooth transition autoregressive, LSTAR, models) the long run behaviour of inflation rates in a pool of African countries. In order to do so, we rely on unit root tests applied to nonlinear...

This paper analyses the empirical fulfilment of the Real Interest Rate Parity (RIRP) theory for a pool of Central and Eastern European Countries. To do so, we apply the recently developed Ng and Perron (2001) unit root tests, that are corrected versions of existing unit root tests and the...

The aim of this paper is to analyse the empirical fulfilment of the Purchasing Power Parity (PPP) theory for the Australian dollar. In order to do so we have applied recently developed unit root tests that account for asymmetric adjustment towards the equilibrium (Kapetanios et al., 2003) and...

Time-series regressions including non-linear transformations of an integrated variable are not uncommon in various fields of economics. In particular, within the Environmental Kuznets Curve (EKC) literature, where the effect on the environment of income levels is investigated, it is standard...

This paper studies business cycle interdependence among the industrialized countries since 1958. Using the spillover index methodology recently proposed by Diebold and Yilmaz (2009) and based on the generalized VAR framework, I develop an alternative measure of comovement of macroeconomic...

The problem of detecting unit roots in univariate and multivariate time series data is treated as a problem of multiple decisions instead of a testing problem, as is otherwise common in the econometric and statistical literature. Four examples for such multiple decision designs are considered:...
