In the analysis below, we provide a rationale for relying on a PPP rather than adopting a more traditional procurement model. With such traditional contracting, G first buys the infrastructure from a given builder and then selects an operator. We thus investigate whether the two tasks of respectively designing/building the assets and operating them should be bundled and performed by the same contractor (a consortium) or instead whether they should be unbundled and undertaken by two separate firms (a builder and a separate operator).
