PPP is presented as a new kind of practice. According to Wettenhall (2005) there is nothing new about the mixing of public-private endeavors (also Greve and Ejersbo 2005). There has always been some degree of public sector and private sector cooperation. Governments have contracted with the private sector for centuries. (Greve & Hodge 2005: 1–2.) The private sector has a long history of being involved in providing infrastructure facilities and services to the public (Grimsey & lewis 2004: 20).
