中文摘要:
本文探讨了一类政府的最优税收与借贷方案:这类政府会担忧模型不确定性,并寻求具有稳健性的决策。定量分析结果表明,模型不确定性的存在会使政府更倾向于借贷,并提升其债务承载能力。在最坏情景下,税收的边际收益与最优税率会先下降、后上升。这一现象源于不确定性引发的两种反向效应之间的博弈。此外,政府应更多地开展金融对冲操作,且其对冲工具持有量不再与债务占 GDP 的比率呈线性关系。
英文摘要:
We consider the optimal tax and borrowing plan of a government that worries about model uncertainty and seeks robust decisions. Quantitative implications show that the presence of model uncertainty makes the government more willing to borrow and enlarges its debt capacity. Under the worst-case scenario, the marginal benefit of taxation and the optimal tax rate decreases first and then increases. This is due to the game between two opposing effects induced by ambiguity. Moreover, the government should engage more in financial hedging while the amount of holdings is no longer linear in the debt-to-GDP ratio.
