This paper examines exchange-rate volatility with GARCH models using monthly exchange-rate return series from 1985:1 to 2011:7 for Naira/US dollar return and from 2004:1 to 2011:7 for Naira/British Pounds and Naira/Euro returns. The study compare estimates of variants of GARCH models with break...

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...

We examine whether the inflation rates of the countries that pursue inflation targeting policies have converged as opposed to the experience of the OECD non-inflation targeters. Using a methodology introduced by Pesaran (2007a), we examine the stationarity properties of the inflation...

In this paper, we propose Phillips-Perron type, semiparametric testing procedures to distinguish a unit root process from a mean-reverting exponential smooth transition autoregressive one. The limiting nonstandard distributions are derived under very general conditions and simulation evidence...

This paper This paper develops a new approach to the problem of testing the existence of a long-run level relationship between a dependent variable and a set of regressors, when it is not known with certainty whether the underlying regressors are trend- or first-difference stationary. The...

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...

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....
