PFI, which stands for Private Finance Initiative, is a financial model used by governments around the world to fund public infrastructure projects. It involves partnering with private sector companies to design, build, finance, and operate these projects, such as hospitals, schools, and transportation systems. The aim is to leverage private sector expertise and capital to deliver high-quality public services and infrastructure. The PFI model has been both praised and criticized for its potential benefits and drawbacks. While it can provide access to much-needed funding and expertise, critics argue that it can be costly in the long run and may result in the privatization of public assets. Overall, understanding the full form of PFI is essential for anyone interested in the financing and delivery of public infrastructure projects.
