Ordering Disorder – On the Perplexities of the Partnership Literature

The literature on public‐private partnerships (PPP) has proliferated in recent years. However, confusion about the actual meaning of PPP still abounds. As a consequence, contradicting findings and statements about PPP flourish in the literature. This article reviews the literature, and argues that there are different streams of PPP research which operate with qualitatively different notions of the PPP concept. Accordingly the literature is divided into four different PPP ‘approaches’. By doing so the article offers some clarification concerning an increasingly complex concept. The article concludes that an authoritative definition of PPP – one that can encompass all the different variations of the concept currently in use – is not logically possible.
