However, the use of external consultants can be a means to acquire competence and knowledge for the benefit of the public-sector party, but it also has limits. First, the use of consultants does not address the problem of corruption. A priori, there is no reason to believe that external consultants maybe less prone to corruption than public sector bureaucrats, although it could be argued that large consultancy firms may have more to loose from being involved in a corruption scandal than single individuals. Second, large consultancy firms that have the specific knowledge to deal with contracts as complex as PPP contracts find themselves hired by the public sector in one contract and by the private sector in another. Working for both sides, although at different points in time, is likely to be conducive to favoritism.
