Dette publique, qualité institutionnelle et croissance économique dans les pays de la région MENA : analyse par la méthode des moments généralisés

Despite the diversity of theoretical studies, the problematic of the public debt – economic growth relationship remains a controversial issue. The aim of the paper is to complement the existing evidence focusing on MENA countries.

The results of robustness tests show that public debt stimulates economic conditions in the countries with sound macroeconomic policies and stable institutions
