Abstract
This study analyzed the structure of private sector participation in 696 public–private partnership (PPP) projects in 12 G-20 countries, through a comparison of fully funded (100%) private sector projects with those substantially funded (51%–99%) and partially funded (50% and below) by the private sector. The main goal of this study is to determine whether PPP is a viable option for revamping America’s infrastructure.
Multiple linear regression was then applied to these data because of the presence of continuous outcomes and multiple independent variables. This method of analysis allowed for the development of predictive models explaining contract length and project costs based on private-sector funding levels, the transport subsector, and other predictors. This study found that substantially funded cases (at 51–99%), or, at the very minimum, partnerships with a private-sector majority (at least 51%) are associated with shorter contract lengths. Partially funded (50% or less) cases are associated with increases in project costs when compared with fully funded (100%) cases.
In the interest of improving the U.S. infrastructure, the results suggest that greater private sector participation should be pursued to the extent possible because this is associated with the shortest contract lengths and lowest project costs. Overall, private sector participation that provides at least 51% of funding was found to be most beneficial, with PPP determined to be a viable option to improve America’s infrastructure.
