This important collection presents an authoritative selection of papers on public private partnerships. The literature is relatively new, and draws on the disciplines of both economics and engineering. As well as examining the recent experience of these schemes - whose evolution has accelerated in recent years - this insightful collection also considers the intellectual origins of the concept, and investigates the organisational and risk management aspects of PPPs. It will be an essential source of reference for all those with an interest in this topical subject.
