Abstract (2. Language): 
In this study, the relation between inflation and inflation uncertainty was examined for the period of 1987:1-2005:6 monthly for the Turkish economy. EGARCH was utilized to get inflation uncertainty. Although there is a bi-directional causality relation between the variables according to Hsiao and Granger approaches, the sign of causality running from inflation uncertainty to inflation as to Granger causality test is not significant. VAR analysis shows that there exist a uni-directional causality relation running from inflation to inflation uncertainty. Shortly, inflation has a strong effect on inflation uncertainty. Achieved empirical results from Granger causality test and VAR analyses support the Friedman-Ball hypothesis in that period.

Bu çalışmada, Türkiye ekonomisinin 1987:01-2005:06 döneminde enflasyon ve enflasyon belirsizliği arasındaki ilişki incelenmiştir. Enflasyon belirsizliğinin ölçülmesinde EGARCH yöntemi kullanılmıştır. Hsiao ve Granger nedensellik testlerine göre çift yönlü nedensellik ilişkisi olmasına rağmen, Granger nedensellik testine göre enflasyon belirsizliğinden enflasyona doğru olan nedenselliğin işareti istatistiksel olarak anlamlı olmadığı görülmektedir. VAR analizi sonuçlarına göre de tek yönlü bir nedensellik ilişkisi mevcut ve bu ilişkinin yönü de enflasyondan enflasyon belirsizliğine doğrudur. Kısaca enflasyonun enflasyon belirsizliği üzerinde güçlü bir etkiye sahip olduğu görülmektedir. Granger nedensellik testi ve VAR analizine dayanarak elde edilen sonuçlar, incelenilen bu dönemde, Friedman-Ball hipotezini desteklemektedir.
