A stochastic concession model for infrastructure projects under build-operate-transfer schemes

Project-focussed literature on public-private partnership (PPP) in developing countries: a critical review

“…Actual cases covered the whole spectrum of project types, including utilities (He et al 2020), transportation (Le et al 2020), and social services projects (Leiringer 2006;Kavishe et al 2019). There was also a small number of hypothetical case studies, all of which, notably, addressed hypothetical transportation projects (Jeerangsuwan et al 2014;Zhu et al 2016;Li et al 2017).…”

“…BOT is mainly used in infrastructure projects as a delivery/financing system by the private sector (Algarni et al 2007). The government allocates the private sector a specific concession period during which it collects revenues by operating and maintaining the infrastructure (Zhu et al 2016;Le et al 2020). We employed 'Construction' or 'Infrastructure' in the search string as a means of ensuring that our search not was not limited to literature focused on building-related construction.…”

“…Several researchers tried to identify the optimal lifespan in BOT projects to maximise benefits to both the public and private sectors. Studies included bridge construction projects (Emamian et al 2017) and road construction projects (Zhu et al 2016). The optimal lifespan for BOT projects can be based on:…”

“…(i) cash flow (Hanaoka and Palapus 2012), (ii) estimation of the economic and social development (Zhang et al 2016), (iii) negotiation between the projects' parties (Zhu et al 2016), and iv) total investment cost (Emamian et al 2017). Regarding the effects of a single-period concession structure as compared with a two-period concession structure, Ye and Tiong (2003) analysed the effects based on time overruns, and suggested the two-period structure would be better at reducing the risk of overruns.…”
