This paper explores how Public-Private Partnerships (PPPs) can serve as a strategic macroeconomic instrument for addressing poverty in Nigeria. Drawing on Keynesian economics and real-world case studies, the author argues that PPPs can bridge infrastructure gaps, create jobs, and improve service delivery. It highlights key challenges—such as weak regulations and political risk—and offers policy recommendations to strengthen PPP frameworks for inclusive development. The publication presents PPPs as a viable path toward sustainable economic growth in Nigeria.
