Public-private partnerships (PPPs) are collaborative agreements between government entities and private sector companies. These partnerships aim to finance, build, and operate projects that serve the public, such as infrastructure, healthcare, and education. By combining resources and expertise, both sectors can achieve better outcomes than they might individually. In a PPP, the government typically provides regulatory support and funding, while the private partner brings in investment and operational efficiency. This arrangement can lead to improved services and reduced costs for taxpayers, as seen in various projects like highways, schools, and public transportation systems.
