We introduce a new smooth transition vector autoregressive model with a Gaussian conditional distribution and transition weights that, for a pth order model, depend on the full distribution of the preceding p observations. Specifically, the transition weight of each regime increases in its relative weighted likelihood. This data-driven approach facilitates capturing complex switching dynamics, enhancing the identification of gradual regime shifts. In an empirical application to the macroeconomic effects of a severe weather shock, we find that in monthly U.S. data from 1961:1 to 2022:3, the shock has stronger impact in the regime prevailing in the early part of the sample and in certain crisis periods than in the regime dominating the latter part of the sample. While the overall evidence is somewhat mixed, this may lend some support to overall adaptation of the U.S. economy to severe weather over time.
我们引入了一种新的平滑过渡向量自回归模型,该模型具有高斯条件分布和过渡权,对于p阶模型,过渡权取决于前p个观测值的完整分布。具体来说,每个政权的过渡权在其相对加权可能性中增加。这种数据驱动的方法有助于捕获复杂的切换动态,增强对渐进政权转移的识别。在对严重天气冲击的宏观经济效应的实证应用中,我们发现,在1961年1月至2022年3月的美国月度数据中,冲击对样本早期和某些危机时期普遍存在的制度的影响强于对样本后期主导制度的影响。尽管整体证据好坏参半,但这可能会为美国经济对恶劣天气的整体适应提供一些支持。

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.
考虑考虑模型不确定性并寻求稳健决策的政府的最优税收和借款计划。定量暗示表明,模型不确定性的存在使政府更愿意借贷并扩大其债务能力。在最坏情况下,税收的边际效益和最优税率先降低后增加。这是由于模棱两可所引起的两种对立效果之间的博弈。此外,政府应更多地参与金融对冲,而持有的债务与gdp之比不再是线性的。

Cap and trade versus tradable performance standard in a production network model with sectoral heterogeneity 具有部门异质性的生产网络模型中的限额与交易与可交易绩效标准

In this paper, we compare the economic and welfare implications of two carbon pricing policies, namely the European Cap and Trade (CaT) regime and the Chinese Tradeable Performance Standard (TPS). The former sets an economy-wide emissions target and forces firms to purchase sufficient certificates. The latter sets an emissions intensity and requires firms with a higher intensity to either abate or buy emissions allowances from firms with lower-than-target intensities. It can be shown that TPS is equivalent to CaT when carbon pricing revenues are redistributed to firms according to output. In a dynamic two-agent general equilibrium model with heterogenous production sectors, we show that TPS outperforms a CaT regime that redistributes carbon revenues to households in a lump-sum manner, both, in terms of output gains and welfare due to lower costs on the production side. However, CaT with labor tax reduction increases welfare most because it alleviates distortions on the production side and improves the income situation of all households.
在本文中,我们比较了两种碳定价政策的经济和福利影响,即欧洲的限额与交易(CaT)制度和中国的可交易绩效标准(TPS)。前者设定了整个经济体的排放目标,并强制企业购买足够的证书。后者设定了一个排放强度,并要求强度较高的企业要么减少排放,要么从低于目标强度的企业那里购买排放配额。结果表明,当碳定价收入按产量再分配给企业时,TPS相当于CaT。在具有异质生产部门的动态双主体一般均衡模型中,我们发现TPS在产出收益和福利方面都优于CaT制度,后者以一次性方式将碳收入重新分配给家庭,这是由于生产侧成本较低。然而,降低劳动税的CaT增加福利最多,因为它缓解了生产端的扭曲,改善了所有家庭的收入状况。

The introduction of an unremunerated retail central bank digital currency (CBDC) is currently under consideration by several central banks. Motivated by the decline in transactional cash usage and the increase in online sales in the UK, this paper provides a theoretical framework to study the underlying drivers of these trends and the welfare implications of introducing an unremunerated retail CBDC. I develop a cash credit model with physical and digital retail sectors, endogenous entry of firms and directed consumer search. Calibrating to UK data between 2010 and 2022 the model suggests that there are positive welfare gains from introducing an unremunerated retail CBDC, but these have likely declined over time.
目前,几家央行正在考虑推出一种无报酬的零售央行数字货币(CBDC)。受英国交易现金使用量下降和在线销售增加的推动,本文提供了一个理论框架来研究这些趋势的潜在驱动因素以及引入无酬零售CBDC的福利影响。我开发了一个现金信贷模型与实体和数字零售部门,企业的内生进入和定向消费者搜索。根据英国2010年至2022年的数据,该模型表明,引入无报酬零售CBDC会带来积极的福利收益,但这些收益可能会随着时间的推移而下降。

We develop an investment and financing model in which a controlling shareholder holds write-down equity and extracts private benefits by diverting the firm's cash flows. The model highlights how write-down equity affects investment and financing decisions, and the aggregate agency costs arising from investment, financing, and private benefits diversion. We find that the write-down equity causes the controlling shareholder to delay investment, choose conservative debt financing, and reduce credit spreads. Additionally, under an exogenous capital structure, there exists an optimal write-down ratio that completely eliminates agency costs related to investment. An increase in the write-down ratio reduces agency costs from private benefits diversion. Conversely, under the optimal capital structure, increasing the write-down ratio increases agency costs related to financing and private benefits diversion. Thus, the write-down equity is an effective financial instrument to reduce agency conflicts between the controlling shareholder and principals (i.e., minority shareholders and debtholders), especially for firms with debt financing constraints.
我们开发了一种投融资模式,在这种模式下,控股股东持有减记股权,并通过转移公司的现金流来获取私人利益。该模型强调了减记股权如何影响投资和融资决策,以及投资、融资和私人利益转移所产生的总代理成本。研究发现,减记股权导致控股股东推迟投资,选择保守的债务融资,降低了信用利差。此外,在外生资本结构下,存在完全消除与投资相关的代理成本的最优减记比率。减记比率的增加降低了私人利益转移的代理成本。相反,在最优资本结构下,增加减记率会增加与融资和私人利益转移相关的代理成本。因此,减记股权是一种有效的金融工具,可以减少控股股东和委托人(即小股东和债权人)之间的代理冲突,特别是对于债务融资受限的公司。

Dynamic incentive contracts with controllable risk 风险可控的动态激励契约

We address a dynamic contracting model in which a principal hires an agent to manage a project. The key new ingredient is that either the principal or the agent can dynamically control the project risk. Increasing the risk has three effects: (i) a positive drift effect due to the risk premium, (ii) a negative drift effect that captures inefficiencies arising from risk-shifting, and (iii) a mechanical mean-preserving spread effect. We show that if the principal instead of agent controls the risk, we get a higher contract efficiency. The higher the agent's promised value, the more pronounced the advantage. The non-contractibility of risk induces the agent's risk-taking behavior. The contract efficiency in the exogenous no-savings environment is higher than that in the endogenous one due to additional costs of no-savings incentives. These findings contribute to the allocation of control rights, bringing forth a corporate governance perspective.
我们解决了一个动态承包模型,其中委托人雇佣代理人来管理项目。关键的新因素是委托方或代理方都可以动态控制项目风险。增加风险有三种影响:(i)由于风险溢价而产生的正漂移效应,(ii)捕获风险转移引起的低效率的负漂移效应,以及(iii)机械均值保持价差效应。结果表明,由委托方而不是代理方控制风险,可以获得更高的合同效率。代理人承诺的价值越高,优势就越明显。风险的不可收缩性诱发了代理人的冒险行为。由于无储蓄激励的额外成本,外生无储蓄环境下的契约效率高于内生无储蓄环境下的契约效率。这些发现有助于控制权的配置,提出了公司治理的视角。

Medicaid work requirements, labor market effects and welfare 医疗补助工作要求,劳动力市场影响和福利

We develop an overlapping generations model with labor supply, health risk, and health insurance choice to evaluate the effects of imposing work requirements for Medicaid eligibility. The model is calibrated to U.S. data and used to simulate counterfactual policies that condition Medicaid access on minimum weekly work hours, with exemptions for the sick and disabled. Our partial and general equilibrium analyses show that such requirements increase labor force participation, reduce Medicaid enrollment, raise the uninsured rate, and boost output. While long-run growth can offset short-run welfare losses, most scenarios lead to net welfare declines for low-income households. High-income households, by contrast, experience welfare gains. When work requirements are extended to include the sick and disabled, the policy yields stronger growth effects and larger welfare gains. Incorporating key features of the Affordable Care Act—such as Medicaid expansion and subsidized private insurance exchanges—creates a less risky environment in which low-income individuals can substitute Medicaid with subsidized private coverage, thereby reducing welfare losses. However, the fiscal burden of insurance subsidies offsets some of the government's savings from Medicaid contraction, resulting in more modest overall growth effects.
我们开发了一个包含劳动力供给、健康风险和健康保险选择的重叠代模型,以评估对医疗补助资格施加工作要求的影响。该模型是根据美国的数据进行校准的,并用于模拟反事实的政策,这些政策将医疗补助计划以每周最低工作时间为条件,病人和残疾人除外。我们的部分均衡和一般均衡分析表明,这些要求增加了劳动力参与率,减少了医疗补助登记,提高了未参保率,并促进了产出。虽然长期增长可以抵消短期福利损失,但大多数情况下会导致低收入家庭的净福利下降。相比之下,高收入家庭的福利则有所增加。当工作要求扩大到包括病人和残疾人时,该政策产生更强的增长效应和更大的福利收益。纳入《平价医疗法案》的关键特征——比如扩大医疗补助和补贴私人保险交易所——创造了一个风险较低的环境,在这个环境中,低收入个人可以用补贴的私人保险代替医疗补助,从而减少福利损失。然而,保险补贴的财政负担抵消了政府从医疗补助计划收缩中节省的部分资金,导致总体增长效果更为温和。

We study how the transmission of monetary policy innovations is affected by the endogenous response of the central bank to macroeconomic aggregates in a two-agent New Keynesian model. We focus on how the stance of monetary policy and the fraction of savers in the economy affect transmission. We show that the indirect effect of an innovation is negative when the indirect real rate effect exceeds the indirect income effect. The relative magnitude of the indirect real rate effect increases with the share of savers and the strength of the central bank's response and decreases with the horizon of the innovation.
在双代理新凯恩斯模型中,我们研究了货币政策创新的传导如何受到中央银行对宏观经济总量的内生反应的影响。我们关注货币政策的立场和经济中储蓄者的比例如何影响传导。研究表明,当间接实际利率效应超过间接收入效应时,创新的间接效应为负。间接实际利率效应的相对大小随着储蓄者比例和央行应对力度的增加而增加,随着创新的广度而减小。

A tractable model of epidemic control and equilibrium dynamics 一个易于处理的流行病控制和平衡动力学模型

We develop a single-state model of epidemic control and equilibrium dynamics, and we show that its simplicity comes at very low cost during the early phase of an epidemic. Novel analytical results concern the continuity of the policy function; the reversal from lockdown to stimulus policies; and the relaxation of optimal lockdowns when testing is feasible. The model's enhanced computational efficiency over SIR-based frameworks allows for the quantitative assessment of various new scenarios and specifications. Calibrated to reflect the COVID-19 pandemic, the model predicts an optimal initial activity reduction of 38 percent, with subsequent stimulus measures accounting for one-third of the welfare gains from optimal government intervention. The threat of recurrent infection waves makes the optimal lockdown more stringent, while a linear or near-linear activity-infection nexus, or strong consumption smoothing needs, reduce its stringency.
我们开发了流行病控制和平衡动力学的单状态模型,并且我们表明,在流行病的早期阶段,它的简单性以非常低的成本获得。新的分析结果涉及政策功能的连续性;从封锁转向刺激政策;在可行的情况下放松最佳封锁。与基于sir的框架相比,该模型提高了计算效率,可以对各种新场景和规范进行定量评估。该模型经过校准以反映COVID-19大流行,预测最优的初始活动减少38%,随后的刺激措施占最优政府干预带来的福利收益的三分之一。复发性感染波的威胁使最佳封锁更加严格,而线性或近似线性的活动-感染联系,或强烈的消耗平滑需求,降低了其严格性。

The threat of recurrent infection waves makes the optimal lockdown more stringent, while a linear or near-linear activity-infection nexus, or strong consumption smoothing needs, reduce its stringency.</div></div>","PeriodicalId":48314,"journal":{"name":"Journal of Economic Dynamics & Control","volume":"178 ","pages":"Article 105145"},"PeriodicalIF":1.9,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines how anticipated, unanticipated, and uncertainty shocks in U.S. government spending affect the term structure of interest rates, showing that fiscal policy design significantly influences the yield curve and financing costs. Combining a recursively-identified fiscal SVAR with an affine term-structure model that incorporates five-year Congressional Budget Office projections and the Economic Policy Uncertainty index, we recover three orthogonal fiscal shocks and trace their effects on bond markets and economic activity. We find that heightened fiscal policy uncertainty induces a flight to quality, causing immediate declines in Treasury yields. Unanticipated spending shocks have a limited impact on yields, underscoring the forward-looking nature of financial markets. Anticipated spending shocks also lower yields as investors adjust expectations about future macroeconomic conditions. Contrary to traditional views, we observe a contractionary effect on real GDP growth, as lower yields reinforce precautionary behavior among households and firms. Our macro-finance framework captures the bidirectional relationship between macroeconomic expectations and financial markets, highlighting the critical role of the yield curve in transmitting fiscal policy shocks to the real economy.
本文考察了美国政府支出的预期冲击、非预期冲击和不确定性冲击如何影响利率期限结构,结果表明财政政策设计显著影响收益率曲线和融资成本。将递归识别的财政SVAR与包含五年国会预算办公室预测和经济政策不确定性指数的仿射期限结构模型相结合,我们恢复了三个正交的财政冲击,并追踪了它们对债券市场和经济活动的影响。我们发现,财政政策的不确定性加剧导致投资者向优质资产外逃,从而导致美国国债收益率立即下降。意外支出冲击对收益率的影响有限,突显出金融市场的前瞻性。随着投资者调整对未来宏观经济状况的预期,预期的支出冲击也压低了收益率。与传统观点相反,我们观察到实际GDP增长的收缩效应,因为较低的收益率加强了家庭和企业的预防行为。我们的宏观金融框架抓住了宏观经济预期与金融市场之间的双向关系,强调了收益率曲线在将财政政策冲击传递给实体经济方面的关键作用。
