Macroeconomic drivers of Public Private Partnership (PPP) projects in low income and developing countries : a panel data analysis

Drawing on a comprehensive panel data of 137 low income and developing countries, this study queries the macro-economic drivers of Public Private Partnership (PPP) in these countries. PPP is mainly used as a method to address infrastructure needs of nation states which cannot allocate their financial resources towards infrastructure investments and/or cannot secure finance through other instruments. Previous studies in the field remain partial as they included a limited number of macro-economic factors and a smaller number of countries. Our findings suggest that general government balance, population size, money supply and the share of investments in GDP are significant determinants of PPP activity.
