The document discusses public-private partnerships (PPPs), including: 1) PPPs involve long-term contracts between private and public entities, where the private entity provides an asset/service and bears risk, while payment is linked to performance. 2) PPPs can improve efficiency, innovation, and access to financing, but involve high transaction costs, require steady income streams, and balancing risk/control is challenging. 3) Risks should be allocated to the party best able to control, impact, and absorb each risk at lowest cost. Typical PPP structures involve a special purpose vehicle contracting with the government.
