An Examination Of Risk Allocation Preferences In Public-Private Partnerships In Nigeria

Abstract

Risk allocation preferences are important elements of Public-Private Partnerships (PPP), as the fundamental
tension in many negotiations between the public and private sector in PPPs usually comes down to the
question: who is responsible for managing a particular risk? Yet research literature suggests that risk
allocation preferences phenomena have not been adequately studied; hence they remain poorly understood. This
paper provides an empirical analysis and study of risk allocation preferences in PPPs in Nigeria.
Research participants (spanning banking, construction, and public sector groups who were selected
through a convenience sampling method) completed an online survey with Likert-type items within six months
(i.e. between June and November 2011) to gauge probabilities of occurrence, risk impact and risk significance
of 46 risk factors pertaining to PPP projects. As data did not meet the assumptions for parametric statistics,
Mann-Whitney U tests were performed to evaluate the ranked differences in the independent variables (46
risk factors) between private and public sector groups.
This paper shows that 27 (59%) out of the 46 risk factors are preferred to be allocated to the
private sector, while 8 (17%) risk factors are to be allocated to the public sector and 11 (24%) of the risk
factors are to be equally shared between the private and public sectors.
