Governments across the world have been preferring public-private-partnerships (PPP) over traditional methods in the past few decades to procure public services for their citizens. Developing countries, like India has the potential to successfully deploy PPP in providing integrated emergency medical services (EMS) like that of the west. This paper provides a base for implementing PPP contractual mechanism, when the government needs to maximize it social surplus or value for money (VFM). Further, the study attempts to observe the relationship between three players in a multiple principal agent model where government and global investor act as the principals and the service providers acts as the agents. This study intends to portray the equilibrium contract set among the three players including analysing moral hazard problems, signalling aspects, incentivization and matching through the entire contract cycle.
