Evaluating Public Sector’s Support Mechanisms for Project Companies Facing Revenue Risk of PPP Projects

In PPP toll road projects, public sector supports project companies that face the risk of revenue, by different mechanisms. It is necessary for the public sector to evaluate these mechanisms before granting them to the private sector. This study evaluates the support mechanisms defined in the Irania...

It is necessary for the public sector to evaluate these mechanisms before granting them to the private sector. This study evaluates the support mechanisms defined in the Iranian PPP toll road projects legislations by real options and compares them with a proposed mechanism.

The impacts of the revenue risk on public and private sectors is evaluated by Monte Carlo simulation in a Flexible-term mechanism, a Flexible-term mechanism alongside a Revenue Guarantee mechanism defined in the legislations, and a Flexible-term mechanism alongside a proposed Guarantee based on Barrier Option.
