Public-private partnerships are a valuable tool in making government services better - and we are just scratching the surface in the U.S. in making best use of them.
Here's a story about how the State of Oklahoma is starting to use the P3 model to improve the recreational uses of the many lakes around the state. While the state's goal is not to make lots of money, I think it's a reasonable expectation that this sort of development will assist in economic activity where recreational facilities are developed, which will likely lead to more state revenue, thus creating a 'virtuous cycle' - and that's the point.
More than 9.3 million people annually visit Oklahoma’s 60,000 acres of state parks, said Gino DeMarco, deputy director of Oklahoma Tourism and Recreation. But park facilities have been deteriorating for decades, he said. “We are looking for public-private partnerships,” he said. “… We’re not necessarily interested in making a whole lot of money off these partnerships. What we’re interested in doing is making it a better experience for the visitor. If we have a nice marina, if we have nice equestrian resources there, a barn or a place for you to store your horses ... what we have are happier guests.”
