The option value of government guarantees in infrastructure projects

Abstract

The participation of private capital in public infrastructure investment projects has been sought by many governments who perceive this as a way to overcome budgetary constraints and foster economic growth. For some types of projects, this investment may require government participation in the form of project guarantees in order to reduce the risk to the private investor, and as a consequence, the government assumes a contingent liability which may have significant future budgetary impacts. We present a minimum traffic guarantee (MTG) real options model that differs from most of the literature in the field by using market data to determine stochastic project parameters. This model can be used to assess the value of these guarantees, allows the government to analyse the cost-benefit of each level of support, and proposes an alternative to limit the exposure of the government while still maintaining the benefits to the private investor. We apply this model to the projected 1000 mile long BR-163 toll road that will link the Brazilian Midwest to the Amazon River. We conclude that the use of public-private partnerships (PPP) with guarantees and caps on total government outlays can be modelled effectively using option pricing methods and can be a solution to attract private investment to high risk public infrastructure projects.Real options, infrastructure projects, toll roads, government guarantees, concessions,

A Two-Factor Uncertainty Model to Determine the Optimal Contractual Penalty for a Build-Own-Transfer Project

“…This argument is common in the literature and is frequently invoked as being one of the reasons why governments actually grant the projects to the private sector (see, for example, Brandao and Saraiva (2008); Zhang and Kumaraswamy (2001)). Being so, one should expect the private firm to invest earlier due to its greater efficiency.…”

“…Various research pieces can be found focusing on one or more of the above research topics. For example, Huang and Chou (2006) valued the MRG and the option to abandon the project by the private firm, and Brandao and Saraiva (2008) also developed a model for infrastructure projects based on the consideration of a Minimum Demand Guarantee. Cheah and Liu (2006) addressed the valuation of demand and revenue guarantees, applying Monte Carlo simulation, and Chiara et al (2007) also applied the same technique to evaluate a MRG, which is only redeemable at specific moments in time.…”

“…Different approaches such as real option models (e.g. Garvin & Cheah 2004;Zhao et al 2004;Chiara et al 2007;Brandao & Saraiva 2008;Cui et al 2004;Vassallo 2006), the neural network modelling (e.g. Sonmez & Ontepeli, 2009, Baalousha & Çelik, 2011, Wilmot & Mei 2005Hegazy & Ayed, 1998;and Sodikov, 2005) and discounted cash flow (DCF) are used for cost evaluation of infrastructure projects.…”

“…For instance, by taking into account shadow cost of public funds and private investors' risk aversion, (Engel et al, 2013) gave the optimal guarantee level under minimum revenue guarantee for intermediate-demand road projects. Finally, there is a number of studies undertaken recently to examine the option value of government guarantees by employing real option models (Ashuri et al, 2012;Brandao and Saraiva, 2008;Lara Galera and Sánchez Soliño, 2010).…”
