Funding and Financing Infrastructure: The Joint Use of Public and Private Finance

Working Paper: CEPR ID: DP13844

Authors: David Martimort; Stephane Straub; Marianne Fay

Abstract: We characterize the structure of financial and regulatory infrastructure contractsand derive conditions under which public and private finance coexist. This requires a combination of regulated prices and public subsidies sufficiently attractive for outside financierpointing at a fundamental trade-off between financial viability and social inclusion. Whileimprovements in the efficiency of bankruptcy procedures facilitate access to private finance,institutional changes lowering the cost of public funds make public finance more attractive.Project data from the PPI database provides support for our findings and reveals an inverseU-shaped pattern, with private finance peaking for countries in the upper-middle incomerange.
