Assessing contingent liabilities in public‐private partnerships (PPPs)
Public-private partnerships (PPPs) can impose important future cost on the government, which in turn create obligations similar to public debt obligations for financing infrastructure investment. Apart from that, government guarantees, typical in PPP contracts, constitute explicit contingent liabilities. The risk that arises from such guarantees must be transparently valued to assess a country’s fiscal profile. In this study, we aim to show that the notion of a PPP as a (set of) contingent claim(s) can also be used to value the PPP public risk. Valuing contingent claims in this manner is important, as it allows us to compare more carefully different set-ups of a PPP. We introduce and analyse the different scenarios that were at the Chilean government’s disposal for executing a transport infrastructure project. Our findings reveal that, for the first years of a PPP programme, the burden on the surplus or deficit will be less in the case of the PPP compared to typical public investment. Secondly, the net contingent PPP flows constitute the real effect on the deficit and correspondingly on the public debt and weaken the government’s fiscal stance. Finally, we attribute a specific price to the PPP public risk introducing CDS valuation with and without counterparty (government) default.
