The Degree of Private Participation in PPPs: Evidence from Developing and Emerging Economies

Abstract

Public–Private Partnerships (PPPs) are used worldwide to reduce the infrastructure gap. Public entities encourage private sector involvement through PPPs, but the degree of such commitment is affected by several factors, related to the specific PPP project and to the institutional and economic environment in the host country. The purpose of this chapter is to perform an empirical analysis of the determinants of the degree of private sector participation in PPPs in developing and emerging countries. This chapter explores fractional response models to explain the degree of private participation in PPPs using data from 2000 to 2014, obtained from the World Bank’s PPI database. The results suggest that the type of project is a key determinant of the degree of private sector involvement. Favourable fiscal conditions and the existence of explicit support from the government (direct or indirect) increase the degree of private involvement. Multilateral support reduces private participation, emphasizing a substitution effect. In the same way, private sector involvement appears as a substitute to overcome failures in countries with poor financial systems. The results are particularly important for public authorities. This chapter identifies key factors that can foster private sector involvement in PPPs. Although the expansion of PPPs is a well-accepted reality, empirical studies that explore factors that affect the degree of private sector involvement are still lacking. This chapter particularly addresses this topic.
