Public Private Partnership: Models, Success, and Lessons

6 min read

TOPIC CLASSIFICATION

Subject: Indian Economy Sub-area: Infrastructure - PPP, Investment Models Difficulty: Medium Weightage: Moderate (1-2 Prelims + Mains on infrastructure)

EXAMINER REASONING

  1. Trap: Thinking all PPP projects involve private financing and asset ownership (varies by model - BOT, BOOT, DBFOT, etc.).
  2. Most confused: PPP vs Privatization - PPP involves risk-sharing with continued public control; privatization transfers ownership entirely.
  3. Key anchor: NITI Aayog PPP framework; VGF (Viability Gap Funding) Scheme, 2005; Model Concession Agreements.
  4. Current affairs hook: NMP (National Monetisation Pipeline) 2022-27; Asset monetisation of highways, railways, power; InvITs/REITs for infrastructure; PPP in airport modernization.
  5. Mains hinge: "PPPs have been successful in some sectors but have failed in others due to flawed contract design and risk allocation. Critically evaluate India's experience with PPPs."
