The absence of any study examining the post-republican period with the Fourier analysis method shows the contribution of this study to the literature. Real exchange rate values for the relevant years were used in the study. These values were obtained using the State Institute of Statistics report.. In the study, Unit Root Tests (ADF, Phillips-Perron) were used assuming that the series were linear and Fourier ADF Unit Root Tests were used assuming that the series were non-linear. The test result shows that the PPP theory is not valid between the relevant years.eninfo:eu-repo/semantics/openAccessJeokimya ve Jeofizikİktisatİstatistik ve OlasılıkArticle821451541219747
