Acerca das PPP

Em tempos, não sei se nos livros de Dan Ariely, ou de Kahneman, ou de Gigerenzer, encontrei uma referência ao sobre-optimismo dos governos quando calculam as taxas de crescimento em projectos como TGV, novos aeroportos, ...
.
Entretanto, encontrei esta peça "Over-optimism in government projects":
"This report looks at a particularly persistent risk management problem – the difficulties caused for government projects by unrealistic expectations and over-optimism.
.
Initiating projects on the basis of unrealistic assumptions is not new. It is a long-standing problem widely recognised by public sector managers and covered in HM Treasury guidance. Yet all too frequently over-optimism results in the underestimation of the time, costs and risks to delivery and the overestimation of the benefits. It undermines value for money at best, and in the worst case leads to unviable projects."
