PPPs provide the illusion that there are ready funds available for infrastructure repair, improvement, and construction at little or no cost. This is not the reality, however. Investors ask for returns through user fees or future taxes. We suggest that governments work under rules that consider not only the benefits, but also the costs, of PPPs. Since the apparent release of budgetary constraints is dangerous and can lead to excessive spending by current governments, at the expense of the future, we propose that the projects be treated in the government balance sheet as if they were public investments. This reduces the temptation to overspend and ensures that PPPs will be chosen for the right reason-that is, they will be chosen when they will lead to significant efficiency gains.
