摘要

This paper studies how nominal debt maturity alters local equilibrium determinacy under flexible prices when fiscal policy returns the face-value debt ratio to a target and monetary policy follows a Taylor rule. With inherited nominal liabilities, the initial price level changes the real debt burden. Long-bond prices then transmit expected interest rates into issuance costs and public-investment adjustment. Determinacy requires inflation feedback to exceed one but remain below a maturity-dependent upper bound; sufficiently aggressive feedback is destabilizing. If the initial real debt ratio is predetermined, the lower-bound orientation returns, but the cutoff remains maturity-dependent. A two-maturity extension shows that debt composition shifts the admissible policy interval, while a separately normalized par short-debt economy is locally indeterminate under the baseline timing. The model admits balanced growth, satisfies the growth-adjusted transversality condition, and can be implemented with explicit money demand and central-bank operations; the cashless specification is its regular limit.

中文摘要

本文研究在弹性价格下,当财政政策将面值债务比率回归至目标水平、货币政策遵循泰勒规则时,名义债务期限如何改变局部均衡确定性。在存在继承性名义负债的情况下,初始价格水平会改变实际债务负担。长期债券价格随后将预期利率传导至发行成本和公共投资调整之中。确定性要求通胀反馈超过1,但保持在依赖于期限的上界之下;足够激进的反馈会破坏稳定。若初始实际债务比率是预先确定的,则下界导向重新出现,但临界值仍依赖于期限。一个两期限扩展表明,债务构成会移动可容许的政策区间,而在基准时序下,一个单独标准化的面值短期债务经济是局部不确定的。该模型允许平衡增长,满足增长调整后的横截性条件,并可通过显性货币需求和中央银行操作加以实施;无现金设定是其正则极限。
