Modeling the impact of government guarantees on toll charge, road quality and capacity for Build-Operate-Transfer (BOT) road projects
Highlights We model the impact of government guarantees on BOT road projects. We incorporate traffic demand uncertainty into our analysis. Toll charge, road quality, and road capacity vary with guarantee levels. Auction reduces impact of government guarantees on toll charge. Some policy implications are derived from model results.
Abstract Government guarantees are frequently used to attract private investors’ participation into Build-Operate-Transfer (BOT) road projects. In this paper, we investigate the impact of government guarantees on toll charge, road quality and road capacity by taking perspective of the private investor. The main results are: (1) Minimum traffic guarantee increases toll charge while decreasing road quality. Under a low guarantee level, minimum traffic guarantee has no impact on road capacity. However, it improves road capacity when a high guarantee level is performed. (2) Under minimum revenue guarantee, if the guarantee level is sufficiently high, the optimal toll charge will be sufficiently large, but road quality and road capacity will approach zero. (3) Price compensation guarantee decreases toll charge and increases both road quality and road capacity. This paper further investigates the impact of government guarantees when the contract is auctioned. We find that auction reduces the impact of government guarantees on toll charge while failing to affect the impact of government guarantees on road quality and capacity. Some policy implications are also derived from our model results.
