By Gabrielle Gurley for The American Prospect – Public-private partnerships may indeed provide the dollars that fearful politicians are unable to pry from the pockets of their tax-averse constituents. But P3s, as they are known in the infrastructure sector, are more complex than they appear to people who just want to get where they’re going. In a new Economic Policy Institute report, “No Free Bridge,” researcher Hunter Blair shows just why these partnerships are far from a “eureka” moment for America’s infrastructure woes. “The idea that P3s allow infrastructure to be built for free is economic snake oil,” Blair said. P3s do not end up saving taxpayers money, especially when policymakers obscure the true costs and the risks.
