This study investigates the long run relationship between exchange rate andexternal reserves in Nigeria during 1990Q1 - 2012Q4. We confirm theexistence of threshold cointegration between the variables in Nigeria, asagainst linear cointegration. Consequently, a two-regime threshold vector error...

This paper investigates the long-run relationship and asymmetric adjustment between the real oil prices and the real bilateral exchange rates of twelve major oil producers and consumers in the world. It uses threshold autoregressive, TAR, and momentum threshold autoregressive, M-TAR models. The...

This paper discusses the levels and trend of external reserves in Nigeria. The relevance of this lies in the fact that it could help to monitor the reserves and throw early warning signal about any economic crisis. Monthly data on Nigeria external reserves for the period January 1999 to...

We examine the daily exchange rate dynamics in selected new EU member states (Czech Republic, Hungary, Poland, Romania, and Slovakia) using GARCH and TARCH models between 1999 and 2006. Despite these countries adopted inflation targeting regime, they occasionally tried to manage their exchange...

We examine the daily exchange rate dynamics in selected EU new member states (Czech Republic, Poland, Romania, and Slovakia) using GARCH and TARCH models between 1999 and 2004. We show that these countries tried to reduce volatility of the spot exchange rate despite their official policy of free...

We propose a common factor approach to analyse convergence, which we implement using principal components analysis. We show that this method provides a useful new way of approaching the convergence debate. We apply this technique to a dataset of nominal and real monthly exchange rates of the...

Long-range persistence in volatility is widely modelled and forecasted in terms of the so-called fractional integrated models. These models are mostly applied in the univariate framework, since the extension to the multivariate context of assets portfolios, while relevant, is not...

This paper investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the US and her top thirteen trading countries. Our investigation also considers those effects on trade flows which may arise through changes in income volatility and the...

In this paper, we investigate the impact of monetary policy signals stemming from the ECB Council and the FOMC on the intradaily Euro-dollar volatility, using high-frequency data (five minutes frequency). For that, we estimate an AR(1)-GARCH(1,1) model, which integrates a polynomials structure...
