The single price law examines the influence of all goods on the economies of a single property like a law. In the comparison of the countries, the price level changes to the currency conversion rate by removing the difference. It equals the general price levels of the countries. Expenditures that convert from a foreign exchange rate to a common currency reveal not only the volume of goods and services purchased but also the price level differences between economies. The emergence of the purchasing power parity is attempting to reveal the similarities and disparities of real goods and service volume by eliminating the price level difference between countries. The purpose of this study, with unit root tests for the economy of Turkey 2003: 1-2018: 4 period is valid is to investigate whether purchasing power parity using monthly data. Conventional ADF KPSS unit root tests, the PP and structural break Zivot Andrews unit root test analyzed for purchasing power parity Turkey is tested to be valid. After the findings and the tests made, the results of the ADF unit root test and the PP unit root test are valid, while the SGP is valid, the KPSS unit root test and the Zivot Andrews fractured unit root test statistic SGP are invalid.
