Satın Alma Gücü Paritesi Hipotezinin Türkiye İçin Geçerliliğinin Araştırılması: Lineer Olmayan Birim Kök Testi

Abstract

Tek fiyat kanunu, satın alma gücü paritesinin temel çerçevesini oluşturur. Satın alma gücü paritesi hipotezinin geçerliliği literatürde halen tartışılmaktadır. Bu çalışma, Türkiye için satın alma gücü paritesi hipotezinin yapısal kırılmalar ve doğrusal olmama koşullarında geçerliliğini incelemektedir. Bu hipotez zaman serisi birim kök sınamaları kullanılarak 2013-2023 dönemi için test edilmiştir. Çalışmada reel döviz kuru verileri kullanılmaktadır ve bu veriler TCMB'den elde edilmiştir. ADF, DF-GLS, Ziwot- Andrews, Lee-Strazicich ve ESTAR birim kök sınamalarına çalışmada yer verilmiştir. Çalışma sonucunda elde edilen bulgu, satın alma gücü paritesi hipotezinin Türkiye için geçerli olduğunu göstermektedir.

Investigation of Validity Purchasing Power Parity Hypothesis for Turkey: Non-Linear Unit Root Test

Abstract

The law of one price establish a basic framework of purchasing power parity. The validity of the purchasing power parity hypothesis is still debated in the literature. This paper examines validity purchasing power parity hypothesis for Turkey under structural breaks and non-linearity conditions. It is tested using times-series unit root tests over the period of 2013-2023. Real exchange rate data is used in this study and this data is collected from TCMB. ADF, DF-GLS, Ziwot-Andrews, Lee-Strazicich and ESTAR unit root tests are implemented in the study. The obtained result from study displays that purchasing power parity hypothesis is valid for Turkey.
