本研究分析了公私合作(PPP)基础设施项目的合同效率,重点关注两个财务方面:无追索权本金和债务合同的不完全性。当保荐公司设立的特殊目的机构(SPV)发生违约时,无追索权委托人解除保荐公司的债务合同。因此,债务合同项下的所有义务仅限于 SPV 违约后的责任。由于债务合同不完整,银行和 SPV 之间可能会重新协商追加贷款,以使项目能够继续或清算,进而影响 SPV 的事前策略(道德风险)。考虑到PPP基础设施项目的这两个财务特征,本研究开发了不完全合同模型来研究重新谈判如何引发事前道德风险和事后低效清算。我们推导了通过招标内生确定的服务费下的均衡策略,并检验了均衡策略对合同效率的影响。最后,我们提出了履约担保、政府终止权和服务费的优化组合,以提高PPP基础设施项目的合同效率。
This study analyses the contractual efficiency of public-private partnership (PPP) infrastructure projects, with a focus on two financial aspects: the nonrecourse principal and incompleteness of debt contracts. The nonrecourse principal releases the sponsoring companies from the debt contract when the special purpose vehicle (SPV) established by the sponsoring companies falls into default. Consequently, all obligations under the debt contract are limited to the liability of the SPV following its default. Because the debt contract is incomplete, a renegotiation of an additional loan between the bank and the SPV might occur to enable project continuation or liquidation, which in turn influences the SPV’s ex ante strategies (moral hazard). Considering these two financial features of PPP infrastructure projects, this study develops an incomplete contract model to investigate how the renegotiation triggers ex ante moral hazard and ex post inefficient liquidation. We derive equilibrium strategies under service fees endogenously determined via bidding and examine the effect of equilibrium strategies on contractual efficiency. Finally, we propose an optimal combination of a performance guarantee, the government’s termination right, and a service fee to improve the contractual efficiency of PPP infrastructure projects.
