Abstract

Bu çalışmada, YTL/US$ döviz kuru getirisinin oynaklık (volatility) içeriği 2001 krizi sonrası dönem için 2008’in erken dönemlerine kadar incelenmektedir. Üssel GARCH (EGARCH) yöntemi kullanılarak elde edilen sonuçlar döviz kuru getirisi üzerindeki oynaklık şoklarının kalıcı olduğunu ve bu şekilde koşullu varyans tahminlerinin durgun duruma oldukça yavaş bir şekilde yakınsadığını göstermektedir. Ayrıca, döviz kuru getirisinin koşullu varyansı aynı büyüklükteki negatif ve pozitif değişikliklere farklı bir şekilde tepki göstermektedir. Haber Etki Eğrisinin (News Impact Curve) çizimi döviz kuru getirisindeki beklenmedik bir artışın beklenmedik bir azalış durumuyla karşılaştırıldığında daha fazla belirsizliğe yol açtığını ortaya koymaktadır

ASYMMETRIC INFORMATION CONTENT OF THE YTL/US$ EXCHANGE RATE RETURN: NEW EVIDENCE FROM THE POST- CRISIS DATA USING ARMA-EGARCH-M MODELING

Year 2008, Volume: 5 Issue: 2, 1 - 10, 01.12.2008

Abstract

In this paper, the volatility content of the YTL/US$ exchange rate return has been examined for the post-2001 crisis period till the early periods of 2008. Using exponential GARCH (EGARCH) methodology, estimation results indicate that volatility shocks on exchange rate return seem to be persistent so that the forecasts of the conditional variance converge to the steady state quite slowly. Besides, conditional variance of the exchange rate return reacts differently to equal magnitude negative and positive innovations. Plotting the News Impact Curve reveals that an unanticipated increase in exchange rate return would lead to more uncertainty when compared with the case of an unanticipated decrease
