A global decline in PPP transactions has been observed in recent years despite the critical need for investments in various sectors, particularly in infrastructure development. Among reasons identified for the loss of confidence in PPPs are approaches taken in PPP contracts to risk allocation and dispute resolution. This brief recommends incremental reforms to current PPP contracting practices, incorporating various alternative arrangements and taking into account the associated governance challenges.

The traditional approach to public infrastructure delivery and management has been challenged in the past decades through different forms of private capital participation. Two well established platforms for private capital participation in the context of public infrastructure procurement are the Regulatory Asset Base (RAB) Model and the Project Finance Model (broadly termed as PPP - Public-Private Partnerships). Based on a literature review, this paper assesses the two vehicles in terms of efficiency in delivery and operation of major infrastructure.
