Exchange-rates volatility in Nigeria : application of GARCH models with exogenous break
Bala, Dahiru A.; Asemota, Joseph O. - In: CBN journal of applied statistics 4 (2013) 1, pp. 89-116
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...

Exploring long memory and nonlinearity in Irish real exchange rates using tests based on semiparametric estimation
Bond, Derek; Harrison, Michael J.; O'Brien, Edward J. - 2009
Deciding whether a time series that appears nonstationary is in fact fractionally integrated or subject to structural change is a diffcult task. However, various tests have recently been introduced for distinguishing long memory from level shifts and nonlinearity. In this paper, three testing...

Exchange rate volatility in Nigeria : consistency, persistency & severity analyses
Adeoye, Babatunde W.; Atanda, Akinwande A. - In: CBN journal of applied statistics 2 (2011) 2, pp. 29-49
The adoption of the International Monetary Fund (IMF) Structural Adjustment Programme (SAP) in 1986 resulted in the transition from fixed exchange rate regime to floating exchange rate regime in Nigeria. Ever since, the exchange rate of naira vis-à-vis the U.S dollar has attained varying rates...

Symmetry and separability in two-country cointegrated VAR models : representation and testing
Krolzig, Hans-Martin; Heinlein, Reinhold - 2013
Introducing the approach by Masanao Aoki (1981) to time series econometrics, we show that the dynamics of symmetric linear possibly cointegrated two-country VAR models can be separated into two autonomous subsystems: the country averages and country differences, where the latter includes the...

Purchasing Power Parity in High Inflation Countries : A Cointegration Analysis of Integrated Variables with Trend Breaks
Zhou, Su - 1998
This paper examines the long-run validity of purchasing power parity (PPP) for four high-inflation countries. The method of Zivot and Andrews (1992) is employed to detect the time-series behavior of the exchange rates and consumer price indices of these countries. We find that these variables...

Volatility transmission and volatility impulse response functions in the main and the satellite Renminbi exchange rate markets
Funke, Michael; Loermann, Julius; Tsang, Andrew - 2020
We analyse volatility spillovers between the on- and offshore (CNY and CNH) Renminbi exchange rates towards the US dollar (USD). The volatility impulse response (VIRF) methodology introduced by Hafner and Herwatz (2006) is applied to several shocks between January 2012 and December 2019....

Filtering the Beer : A Permanent and Transitory Decomposition
Clark, Peter B.; MacDonald, Ronald - 2021
In this paper we extend the BEER (Behavioral Equilibrium Exchange Rate) approach which identifies an estimated … Permanent Equilibrium Exchange Rate, or PEER, for the U.S. and Canadian dollars and the pound sterling. The BEER and the PEER … pound sterling the BEER and the PEER diverge sharply, with the latter following the actual exchange rate quite closely …

Covered interest parity : a stochastic volatility approach to estimate the neutral band
Hernández, Juan Ramón - 2020
The neutral band is the interval where deviations from Covered Interest Parity (CIP) are not considered meaningful arbitrage opportunities. The band is determined by transaction costs and risk associated to arbitrage. Seemingly large deviations from CIP in the foreign exchange markets for the US...

Exchange Rate Misalignment Estimates – Sources of Differences
Cheung, Yin-Wong - 2011
We study the differences in currency misalignment estimates obtained from alternative datasets derived from two International Comparison Program (ICP) surveys. A decomposition exercise reveals that the year 2005 misalignment estimates are substantially affected by the ICP price revision....
