معدل صرف الدينار الجزائري بين فرضيتي تعادل القوة الشرائية و صيرورة النزهة العشوائية : دراسية قياسية اقتصادية للفترة 1980-2017

الملخص EN

This study aims to investigate the Algerian dinar’s exchange rate tendency to the PPP hypothesis or to a random walk process, using monthly data going from January 1980 up to December 2017.

Based on first and second-generation unit root tests, alongside unit root tests with gradual and discrete structural breaks (Innovation Outlier, Additive Outlier).

The results of this study show that Algerian dinar’s exchange rate exhibits a long-run relation with the PPP’s proposition under the gradual structural break case.

Contrarily, no relation in the cases of the discrete structural break or using the first and second-generation unit root tests.
