THE VALIDITY OF DIFFERENT VERSIONS OF PURCHASING POWER PARITY VERSIONS: EVIDENCE FROM TURKEY

Abstract

In this study, we investigated different versions of purchasing power parity PPP for Turkey over the period January 1980 – December 2012. The test results we obtained show that purchasing power parity is not valid for Turkey. However, by employing unit root tests which allow structural breaks in intercept and intercept and also trend, we conclude that Qualified PPP and Qualified-Trend PPP with structural breaks is valid.

SATIN ALMA GÜCÜ PARİTESİ ve VARYASYONLARININ TÜRKİYE İÇİN SINANMASI

Öz

Bu çalışmada Türkiye’de satın alma gücü paritesinin ve çeşitli varyasyonlarının geçerliliği Ocak 1980 – Aralık 2012 dönemi için, reel döviz kurunu çeşitli veri yaratma süreçleriyle modelleyerek sınanmıştır. Yapılan testler sonrasında, Türkiye’de satın alma gücü paritesinin geçerli olmadığı görülmektedir. Bununla birlikte, çoklu yapısal kırılmaya izin veren birim kök testleriyle yapılan analizde, sadece sabit terimde ve sabit terim ile trend terimlerinde kırılmaya izin veren birim kök testlerinde, reel döviz kuru durağan bulunmuştur. Elde edilen bu sonuçlar, Türkiye’de sınırlı SAGP ile Kırılmalı-Trendli-Sınırlı SAGP’nin geçerli olduğunu göstermektedir.
