Based on a method developed by Leybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the NASDAQ stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

In this paper we aim to analyse the dynamics of unemployment in a group of Central and Eastern European Countries (CEECs). The CEECs are of special importance for the future of the European Union, given that most of them have recently become member states, and labour flows have been seen to rise...

In this paper we provide an insight into the inflation dynamics in a panel of Central and Eastern European countries. These countries are selected because of their increasing importance in the EU and their likely increased future importance in monetary policy decisions inside the euro area. By...

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...

Unit root tests are the starting point of most empirical time series research. This paper analyses the order of integration of oil prices taking into account the possibilities of nonlinearities in the deterministic components. Using an aggregate index for the price of oil, and applying Bierens...

The aim of this paper is to analyse the empirical fulfilment of the PPP in Australia (1977-2004). Previous research focuses on the presence of structural breaks and fails to find any support to the PPP (Darne and Hoarau, 2008, Henry and Olekalns, 2002). In contrast, we find that the PPP...

The aim of this paper is to analyse the existence of price convergence in Mercosur. Two variables are considered, Consumer Price Indices to assess convergence in the goods and services markets and real interest rates, to analyse convergence in the money markets. The univariate analysis points...

In this paper we aim at modelling the long run behaviour of the Real Effective Exchange Rates (REER) for a pool of African countries. Not much attention has been paid to this group of countries, in particular, to the existence of nonlinearities in the long run path of such a variable....

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...
