أثر سياسة التيسير الكمي على التضخم في المدى الطويل في الولايات المتحدة الأمريكية: دراسة قياسية معتمدة على مقاربة Sims

الملخص EN

This study aims to investigate the impact of quantitative easing policy on the inflation rate in the USA by studying the long-run causal relationship between quantitative easing and inflation rate, by taking the data for the period from the third quarter of 2008 to the last quarter of 2018.

in order to analyze these data, we applied different statistical tools.

first, we performed the unit root test and found that both series are stationary at the level form.

hence, we used the causality test of sims approach, which depends on the original series to test the existence of a long-run causal relationship between the study variables.

the results indicate that there is a bidirectional relationship between the quantitative easing and the inflation in the USA.

then, the study recommends that the QE policy should not be overstated.
