论文摘要
本文研究了社会折现率（SDR）选择对由公私伙伴关系（PPPS）项目引起的代际权益问题的影响。实际上，更多的PPP意味着将产生财政赤字危机的子孙后代积累更多的债务。该论文借鉴了当今所采用的SDR级别如何在社会福利功能（SWF）上分发社会。这是通过回答两个子问题来完成的：（i）PPPS债务不平衡的风险是什么？ （ii）如何基于所设想的SDR，位置社会在不同的道德观点中的公共政策？答案是从对不同的SDR（在英国应用）的讨论根据相关的道德理论的优点，即自由主义者，自由主义者，平等主义者，功利主义和罗尔西安。我们发现，公共政策制定者可以操纵SDR，使PPP看起来比传统融资表更好。但是，这使价值与货币原则的价值相结合。我们还指出，公共政策并不与道德理论保持一致。我们发现目前（在英国），SDR在权衡曲线中的加权功利主义和罗尔西亚社会之间。 las，我们的研究没有发现（英国）政府正在使用复杂的制度来跟上累积的债务债务。因此，由于不确定性因素，几乎无法做出最终状态的确切预测。我们得出的结论是，我们的研究希望为决策者提供一个良好的分析框架，以便在启动PPP等公共政策之前借鉴道德理论的优点。
This paper investigates the impact of Social Discount Rate (SDR) choice on intergenerational equity issues caused by Public-Private Partnerships (PPPs) projects. Indeed, more PPPs mean more debt being accumulated for future generations leading to a fiscal deficit crisis. The paper draws on how the SDR level taken today distributes societies on the Social Welfare Function (SWF). This is done by answering two sub-questions: (i) What is the risk of PPPs debts being off-balance sheet? (ii) How do public policies, based on the envisaged SDR, position society within different ethical perspectives? The answers are obtained from a discussion of the different SDRs (applied in the UK for examples) according to the merits of the pertinent ethical theories, namely libertarian, egalitarian, utilitarian and Rawlsian. We find that public policymakers can manipulate the SDR to make PPPs looking like a better option than the traditional financing form. However, this antagonises the Value for Money principle. We also point out that public policy is not harmonised with ethical theories. We find that at present (in the UK), the SDR is somewhere between weighted utilitarian and Rawlsian societies in the trade-off curve. Alas, our study finds no evidence that the (UK) government is using a sophisticated system to keep pace with the accumulated off-balance sheet debts. Thus, the exact prediction of the final state is hardly made because of the uncertainty factor. We conclude that our study hopefully provides a good analytical framework for policymakers in order to draw on the merits of ethical theories before initiating public policies like PPPs.
