Abstract

Bu çalışma, 1982–2008 dönemi için Türkiye’de enflasyon ile enflasyon belirsizliği arasındaki nedensellik ilişkisinin varlığını ve yönünü sorgulamaktadır. Otoregresif enflasyon modellerine ilişkin ARCH, GARCH ve PARCH tahminlerinden elde edilen varyans serileri ile enflasyon serisi arasındaki nedensellik analizi, Türkiye’de yüksek enflasyonun, enflasyon belirsizliğini arttırdığı sonucunu desteklemektedir. Bunun yanında, kısa dönemde enflasyon belirsizliğinin yüksek enflasyonun nedeni olduğu sonucuna da ulaşılmaktadır. Ulaşılan bu sonuç, kısa dönemde merkez bankasının enflasyon sürprizlerine başvurma eğiliminin bir göstergesi olarak yorumlanabilir.
