Haircut, interest rate, and collateral quality in the tri-party repo market: Evidence and theory

三方回购市场中的折扣率、利率与抵押品质量:证据与理论

Review of Economic Dynamics · 2026, 61 · Sangyup Choi、Inkee Jang、Kee-Youn Kang、Hyunpyung Kim ·

公共治理货币与金融监管

利用韩国三方回购市场的交易层面数据,我们研究回购合约条款如何与抵押品质量相互作用。折扣率与利率均随抵押品风险上升,这与既有证据一致。然而,在给定抵押品质量的条件下,我们发现二者之间存在权衡关系:利差每上升1个百分点,折扣率相应下降1.3个百分点。在市场不确定性加剧时,同样幅度的利率上升所对应的折扣率降幅更小,这表明随着违约风险上升,针对违约的保险变得更有价值。我们证明,贷款人获取信息的激励与借款人机会主义违约风险之间的相互作用,既解释了折扣率与利率之间正的无条件关系,也解释了二者之间负的条件关系。

英文原文

Using transaction-level data from the Korean tri-party repo market, we study how repo contract terms interact with collateral quality. Both haircuts and interest rates rise with collateral risk, consistent with existing evidence. Conditional on collateral quality, however, we find a trade-off: a one-percentage-point increase in the spread is associated with a 1.3-percentage-point reduction in the haircut. The same increase in the interest rate is associated with a smaller reduction in the haircut under heightened market uncertainty, indicating that insurance against default becomes more valuable as default risk rises. We show that the interaction between lenders’ incentives to acquire information and borrowers’ opportunistic default risk explains both the positive unconditional relationship and the negative conditional relationship between haircuts and interest rates.

Cash Heterogeneity and the Payout Channel of Monetary Policy

现金异质性与货币政策的派息渠道

The Journal of Finance · 2026, 81(4) · ALTAN PAZARBAŞI ·

公共治理货币与金融监管

本文提供了新的经验证据:面对扩张性货币政策冲击,现金充裕的企业具有更高的股权派息和更高的股价。尽管企业对货币政策的现金流、投资和信贷反应较弱,股价仍会上升。我在一个异质性企业的新凯恩斯模型中对此经验证据加以解释,在该模型中企业以现金和股权发行来为投资融资。货币宽松削弱了预防性现金需求,使现金充裕的企业将多余资金最优地分配给股东。由于派息具有顺周期性,现金充裕的企业在扩张期获得更高的回报。我的发现凸显了货币政策影响资产价格的一条派息渠道。

英文原文

ABSTRACT This paper provides novel empirical evidence that cash‐rich firms have higher equity payouts and higher stock prices in response to expansionary monetary policy surprises. Stock prices rise despite weak cash‐flow, investment, and credit responses to monetary policy. I rationalize the empirical evidence in a heterogeneous‐firm New Keynesian model where firms finance investment with cash and equity issuance. Monetary easing weakens precautionary cash demand, leading cash‐rich firms to optimally allocate excess funds to shareholders. Since payouts are procyclical, cash‐rich firms earn higher returns in expansionary periods. My findings highlight a payout channel through which monetary policy impacts asset prices.

Monetary Policy and Wealth Effects: The Role of Risk and Heterogeneity

消费公共治理居民消费货币与金融监管

我们研究资产重估在货币传导机制中的作用。我们构建了一个解析性的异质性个体模型,包含两个主要要素:(i)罕见灾难与(ii)异质性信念。该模型在嵌套教科书式新凯恩斯模型的设定中,刻画了时变风险溢价与预防性储蓄。模型生成货币冲击后资产价格的大幅变动,但这些变动对实际变量可能是中性的。实际效应取决于具有异质性预防性动机的个体之间的再分配。在定量分析中,我们发现这一渠道可以解释向总量消费传导的很大一部分。

英文原文

ABSTRACT We study the role of asset revaluation in the monetary transmission mechanism. We build an analytical heterogeneous‐agents model with two main ingredients: (i) rare disasters and (ii) heterogeneous beliefs. The model captures time‐varying risk premia and precautionary savings in a setting that nests the textbook New Keynesian model. The model generates large movements in asset prices after a monetary shock but these movements can be neutral on real variables. Real effects depend on the redistribution among agents with heterogeneous precautionary motives. In quantitative analysis, we find that this channel can account for a large fraction of the transmission to aggregate consumption.

The Debt Capacity of a Government

政府的债务承受能力

Management Science · 2026, 72(9) · Bernard Dumas、Paul Ehling、Chunyu Yang ·

财政收入政府债务

过度债务的财政成本应予以动态评估,以反映预期的增长、赤字与利率。通过研究这些变量的联合行为,并在世代交叠和源自社会保障的结构性赤字背景下,我们将政府债务承受能力定义为:在当前财政参数保持不变的情况下,恰好能够一直维持直至某个不稳定稳态的债务水平,在该稳态中,基本赤字将永远持续。低于承受能力时,债务收敛至一个稳定的稳态;超过承受能力时,债务将发散失控。若要超出承受能力而不致失控,就需要未来更高的税收或削减支出,这才是真正的财政成本。引入货币之后,若泰勒系数小于一,承受能力会随目标名义利率的上升而提高。通过补贴创新来提高承受能力颇具挑战,因为其收益很难超过成本。本文由 Lukas Schmid(金融)录用。资助:P.

英文原文

Fiscal costs of excessive debt should be assessed dynamically reflecting anticipated growth, deficits, and interest rates. Studying their joint behavior, with overlapping generations and structural deficits arising from social security, we define government debt capacity as the level that can be just sustained with current fiscal parameters unchanged all the way to an unstable steady state, in which primary deficits last forever. Below capacity, debt converges to a stable steady state. Above capacity, debt unravels. Exceeding capacity without unraveling requires higher future taxes or reduced expenditures, which is the true fiscal cost. With money, capacity increases with the target nominal interest rate if the Taylor coefficient is below one. Increasing capacity by subsidizing innovation is challenging as benefits hardly surpass costs. This paper was accepted by Lukas Schmid, finance. Funding: P.

Self-Fulfilling Debt Crises with Long Stagnations

长期停滞下的自我实现型债务危机

Journal of Political Economy · 2025, 133(12) · João Ayres、Gastón Navarro、Juan Pablo Nicolini、Pedro Teles ·

财政收入政府债务

我们定量评估了预期驱动的主权债务危机的重要性,重点关注2010年代初的南欧危机和2001年阿根廷违约。多重均衡的来源是Calvo所提出的一种机制。对多重均衡而言至关重要的是一个以长期高增长或长期停滞为特征的产出过程,我们利用这些国家的数据对该过程进行了估计。我们的分析表明,预期驱动的债务危机在数量上具有重要性,但具有状态依赖性,因为它们只在停滞时期发生。预期及其对政策的反应,是解释西班牙与阿根廷之间违约率和信用利差差异的主要因素。

英文原文

We assess the quantitative relevance of expectations-driven sovereign debt crises, focusing on the southern European crisis of the early 2010s and the Argentine default of 2001. The source of multiplicity is the one proposed by Calvo. Crucial for multiplicity is an output process characterized by long periods of either high growth or stagnation, which we estimate using data for these countries. Our analysis suggests that expectations-driven debt crises are quantitatively relevant but state dependent, as they occur only during periods of stagnation. Expectations and how they respond to policy are the major factors explaining default rates and credit spread differences between Spain and Argentina.

Time Consistency and Duration of Government Debt: A Model of Quantitative Easing

时间一致性与政府债务期限:一个量化宽松模型

本文提出了一个短期名义利率处于零下限(ZLB)时的量化宽松(QE)模型。QE 会缩短政府债务的期限,其在零下限处有效,是因为它在一个时间一致的均衡中产生了对未来货币扩张的预期。数值实验表明,这一效应可能相当可观。

英文原文

This article presents a model of quantitative easing (QE) at the zero lower bound (ZLB) on the short-term nominal interest rate. QE, which reduces the maturity of government debt, is effective at the ZLB because it generates expectations of future monetary expansion in a time-consistent equilibrium. Numerical experiments show that this effect can be substantial.

Money as a Unit of Account

作为记账单位的货币

Econometrica · 2017, 85(5) · Matthias Doepke、Martin Schneider ·

未归类E 宏观与货币经济学

我们构建了一个理论,为经济中主导记账单位的使用提供合理化解释。行为人与各类商业伙伴签订非或有合同。交易沿信用链依次展开,并受随机匹配的约束。通过使用主导记账单位,行为人可以降低其面临的相对价格风险敞口,避免代价高昂的违约,并创造更多总剩余。我们讨论了在何种条件下采用流通中的政府纸币作为主导记账单位是最优的,以及当区域内和区域间的贸易强度存在差异时"货币区"的最优选择问题。

英文原文

We develop a theory that rationalizes the use of a dominant unit of account in an economy.Agents enter into non-contingent contracts with a variety of business partners.Trade unfolds sequentially in credit chains and is subject to random matching.By using a dominant unit of account, agents can lower their exposure to relative price risk, avoid costly default, and create more total surplus.We discuss conditions under which it is optimal to adopt circulating government paper as the dominant unit of account, and the optimal choice of "currency areas" when there is variation in the intensity of trade within and across regions.
