This study analyses the long-run validity of the purchasing power parity (PPP) between Turkey and its major trading partners (China, Euro Area, Russia, United Kingdom, and United States) by using the Fourier quantile unit root test. Fourier quantile unit root test results show that PPP is valid for all countries. Additionally, the Fourier quantile unit root test presents more evidence in favour of the PPP hypothesis in comparison to conventional and other Fourier-type unit root tests.
