Satınalma Gücü Paritesinin OECD Ülkeleri için Test Edilmesi: Fourier Kantil Birim Kök Testinden Bulgular

Satınalma gücü paritesi, döviz kuru belirleme teorileri arasında en eski ve en tartışmalı yaklaşımlardan biridir. Bu çalışma, satınalma gücü paritesinin uzun dönemli geçerliliğini 36 OECD ülkesi için Fourier kantil birim kök testi ile incelenmeyi amaçlamaktadır. Analizler 1993:1-2018:8 aylık dönemleri kapsamaktadır. Fourier kantil birim kök testi sonuçları, 24 OECD ülkesi için satınalma gücü paritesinin geçerli olduğunu ortaya koymaktadır. Bu durum, söz konusu 24 OECD ülkesinde yer alan döviz kurlarının nispi fiyat değişikliklerine uyum sağladığını ve satınalma gücü paritesi teorisinin bu ülkeler için güvenilir bir döviz kuru belirleme aracı olarak kullanılabileceğini ifade etmektedir.

Testing the Purchasing Power Parity for the OECD Countries: Evidence from Fourier Quantile Unit Root Test

Purchasing power parity is one of the oldest and most controversial approaches among theories of exchange rate determination. This study aims to analyze the long-run validity of purchasing power parity for 36 OECD countries using the Fourier quantile unit root test. Monthly observations are used from 1995:1 to 2018:12. Fourier quantile unit root test results show that purchasing power parity is valid for 24 OECD countries. This reveals that the exchange rates in these countries adapt to the price differences and therefore, purchasing power parity theory can be used as a reliable exchange rate determination policy for the countries.
