With the release of US Treasury Secretary Tim Geithner's latest plan  to clear bad loans off the books of troubled banks in the US, the fact that the elaborate auction is essentially a public-private partnership has flown under the radar amidst celebrations and critiques.
Public-private partnerships  (PPPs) are a relatively old tool of development work. PPPs are often implemented in developing countries for large-scale infrastructure projects, landscape or agricultural improvements, or any number of other "public goods" projects. Typically, governments will finance part or all of the project, while private firms will carry out the construction or operation of the project.
PPPs have many benefits. Joined with the private sector, projects often escape the inefficiency and corruption that plagues much government work. By providing such large amounts of capital or start-up money, which many private sectors lack, governments help to spur business in a (hopefully) transparent environment, enforcing regulations and helping to create the foundations of a healthy, complex business sector.
Not only do such connections often help increase aid effectiveness  but they also help to transfer knowledge and technology in both the public and private sectors. For developing countries that need high-level technologies to combat difficult global problems - such as boosting agricultural production, combating global warming with clean energy, and building "smart," green infrastructure - PPPs offer the opportunity to engage proven, global firms in their efforts. It's much easier to entice competent private firms to play a role in development when they're given the opportunity to turn a profit - and that's just what PPPs do.
The transfer of such knowledge, especially when coupled with continuing education efforts, allows "hard" projects in infrastructure, manufacturing, and energy, to provide a model for "soft" initiatives aimed at improving the social realities of daily life in the developing world. Policymakers should take notice  - governments don't have to help out the private sector only in a crisis. Improving schools, public health, and housing will all require the help, and knowledge, of businesses throughout the world.
