Governments globally have embraced Public-Private Partnerships (PPPs) to reduce fiscal burdens and transfer responsibilities to the private sector. However, the long-term viability of this approach remains uncertain due to social and economic limitations. To offer decision-makers involved in PPP initiatives worldwide with valuable insights for shaping their PPP programs, this thesis undertakes a comprehensive analysis of the lasting social and financial implications of the United Kingdom's Private Finance Initiative (PFI) and its subsequent iteration, PF2. The PFI and PF2 programs in the UK were chosen as the unit of analysis because they represent one of the largest PPP programs around the globe, encompassing a diverse portfolio of over 700 projects.
