Using a quantitative sovereign default model, we characterize constrained efficient borrowing by a Ramsey government that commits to income-history-contingent borrowing paths taking as given ex-post optimal future default decisions. The Ramsey government improves upon the Markov government because it internalizes the effects of borrowing decisions in period t on borrowing opportunities prior to t. We show the effect of borrowing decisions in t on utility flows prior to t can be encapsulated by two single dimensional variables. Relative to a Markov government, the Ramsey government distorts borrowing decisions more when bond prices are more sensitive to borrowing, and changes in bond prices have a larger effect on past utility. In a quantitative exercise, more than 80% of the default risk is eliminated by a Ramsey government, without decreasing borrowing. The Ramsey government also has a higher probability of completing a successful deleveraging (without defaulting), while smoothing out the fiscal consolidation.
使用定量主权违约模型,我们描述了拉姆齐政府的约束有效借款,该政府承诺采用收入历史条件下的借款路径,并将其作为给定的事后最优未来违约决策。拉姆齐政府比马尔可夫政府改进,因为它内化了t时期借款决策对t之前借款机会的影响。我们展示了t时期借款决策对t之前效用流的影响可以用两个单维变量来封装。相对于马尔可夫政府,当债券价格对借贷更敏感时,拉姆齐政府更容易扭曲借贷决策,债券价格的变化对过去效用的影响更大。通过定量分析,在不减少借贷的情况下,拉姆齐政府消除了超过80%的违约风险。拉姆齐政府在顺利完成财政整顿的同时,也更有可能成功地完成去杠杆化(不违约)。

Anchoring of inflation expectations is of paramount importance for central banks’ ability to deliver stable inflation and minimize price dispersion. Relying on daily interest rates and inflation forecasts from major financial institutions in the United States, we calculate monetary policy surprises of individual analysts as the unexpected changes in the federal funds rate before the meetings of the Federal Reserve Board. We then assess the effect of monetary policy surprises on the dispersion of inflation expectations, a proxy for the extent of anchoring, which is based on the same analysts’ inflation projections submit-ted after the Fed meetings. With an identification strategy that hinges on a tight window around the Fed meetings, we find that monetary policy surprises lead to an increase in the dispersion of inflation expectations up to nine months after the policy meeting. We rationalize these results with a partial equilibrium model that features rational expectations and sticky information. When we allow the degree of information rigidity to depend on the realization of firm-specific shocks, the theoretical results are qualitatively consistent and quantitatively close to the empirical evidence.
锚定通胀预期对于央行实现稳定通胀和最小化价格差异的能力至关重要。根据美国主要金融机构的每日利率和通胀预测,我们将个别分析师的货币政策意外值计算为联邦储备委员会会议前联邦基金利率的意外变化。然后,我们评估货币政策意外对通胀预期分散度的影响,这是锚定程度的代理,这是基于美联储会议后提交的相同分析师的通胀预测。我们的识别策略取决于美联储会议前后的短暂窗口期,我们发现,货币政策意外导致通胀预期的分散性在政策会议后长达9个月的时间里增加。我们用一个具有理性预期和粘性信息的部分均衡模型来合理化这些结果。当我们允许信息刚性的程度取决于企业特定冲击的实现时,理论结果在质量上是一致的,在数量上接近经验证据。

This paper explores three possible transmission channels for transition risk shocks to the financial system in Norway. First, we estimate the direct firm-level impact of a substantial increase in domestic carbon prices under severe assumptions. Second, we map the impact of a drastic increase in global carbon prices on the domestic economy via the Norwegian oil sector. Third, we model the impact of a forced reduction in Norwegian oil firms’ output on shareholder portfolios. Results show that such a sharp increase in carbon prices would have a significant but manageable impact on banks. Finally, the paper discusses ways to advance the still evolving field of transition risk stress testing.
本文探讨了转型风险冲击对挪威金融体系的三种可能的传导渠道。首先,我们在严格的假设下估计了国内碳价格大幅上涨对企业层面的直接影响。其次,我们通过挪威石油部门绘制了全球碳价格急剧上涨对国内经济的影响。第三,我们模拟了挪威石油公司产量被迫减少对股东投资组合的影响。结果表明,碳价格的大幅上涨将对银行产生重大但可控的影响。最后,本文讨论了如何推进仍在发展中的转型风险压力测试领域。

What Do We Talk About When We Talk About Output Gaps? 当我们谈论产出缺口时,我们在谈论什么?

Estimates of output gaps continue to play a key role in assessments of the stance of business cycles. This paper uses three approaches to examine the historical record of output gap measurements and their use in surveillance within the IMF. Firstly, the historical record of global output gap estimates shows a firm negative skew, in line with previous regional studies, as well as frequent historical revisions to output gap estimates. Secondly, when looking at the co-movement of output gap estimates and realized measures of slack, a positive, but limited, association is found between the two. Thirdly, text analysis techniques are deployed to assess how estimates of output gaps are used in Fund surveillance. The results reveal no strong bearing of output gap estimates on the coverage of the concept or direction of policy advice. The results suggest the need for continued caution in relying on output gaps for real-time policymaking and policy assessment.
对产出缺口的估计继续在评估商业周期状况方面发挥关键作用。本文使用三种方法来研究产出缺口测量的历史记录及其在国际货币基金组织内部监督中的应用。首先,全球产出缺口估计的历史记录显示出明显的负倾斜,这与之前的区域研究一致,而且对产出缺口估计的历史修正也很频繁。其次,当观察产出缺口估计值和已实现的闲置指标的共同运动时,发现两者之间存在积极但有限的关联。第三,采用文本分析技术来评估产出缺口的估计如何用于基金组织的监督。结果显示,产出缺口估计与政策建议的概念覆盖面或方向没有很强的相关性。研究结果表明,在依赖产出缺口进行实时政策制定和政策评估时,需要继续保持谨慎。

Not anytime soon. Using a novel dataset covering 127 countries and spanning two centuries, we find evidence for an energy Kuznets curve, with an initial decline of energy demand at low levels of per capita income followed by stages of acceleration and then saturation at high-income levels. Historical trends in energy efficiency have reduced energy demand, globally, by about 1.2 percent per year and have, thus, helped bring forward a plateau in energy demand for high income countries. At middle incomes energy and income move in lockstep. The decline in the manufacturing share of value added, globally, accounted for about 0.2 percentage points of the energy efficiency gains. At the country level, the decline (rise) of the manufacturing sector has reduced (increased) US (China) energy demand by 4.1 (10.7) percent between 1990 and 2017.
短期内不会。利用一个涵盖127个国家、跨越两个世纪的新数据集,我们发现了能源库兹涅茨曲线的证据,即在人均收入水平较低时,能源需求开始下降,随后在高收入水平时,能源需求出现加速和饱和阶段。能源效率的历史趋势使全球能源需求每年减少约1.2%,从而帮助高收入国家实现了能源需求的平稳期。在中等收入人群中,精力和收入的变化是同步的。全球制造业增加值份额的下降,约占能源效率增长的0.2个百分点。在国家层面,制造业的下降(上升)使美国(中国)的能源需求在1990年至2017年期间减少(增加)了4.1%(10.7%)。

The paper uses firm-level data to assess the financial health of the Vietnamese non-financial corporate sector on the eve of pandemic. Our analysis finds that smaller domestic firms were particularly vulnerable even by regional comparison. A sensitivity analysis suggests that the COVID-19 shock will have a substantial impact on firms’ profitability, liquidity and even solvency, particularly in the hardest hit sectors that are dominated by SMEs and account for a sizeable employment share, but large firms are not immune to the crisis. Risks of default can propagate more broadly through upstream and downstream linkages to industries not directly impacted, with stresses potentially translating into an increase in corporate bankruptcies and bank fragility. Policy measures taken in the immediate aftermath of the crisis have helped alleviate liquidity pressures, but the nature of policy support may have to pivot to support the recovery.
本文使用企业层面的数据来评估越南非金融企业部门在大流行前夕的财务健康状况。我们的分析发现,即使通过地区比较,规模较小的国内企业也特别脆弱。一项敏感性分析表明,2019冠状病毒疫情的冲击将对企业的盈利能力、流动性甚至偿付能力产生重大影响,特别是在受影响最严重的行业,这些行业以中小企业为主导,占据了相当大的就业份额,但大公司也不能幸免于危机。违约风险可以通过不受直接影响的行业的上下游联系更广泛地传播,压力可能转化为企业破产和银行脆弱性的增加。危机后立即采取的政策措施帮助缓解了流动性压力,但政策支持的性质可能不得不转向支持复苏。

Imported Food Price Shocks and Socio-Political Instability: Do Fiscal Policy and Remittances Matter? 进口食品价格冲击与社会政治不稳定:财政政策和汇款重要吗?

Using a panel of 101 low- and middle-income countries with data covering the period 1980-2012, this paper applies various econometric approaches that deal with endogeneity issues to assess the impact of food price shocks on socio-political instability once fiscal policy and remittances have been accounted for. It focuses on import prices to reflect the vulnerability of importer countries / net-buyer households to food price shocks. The paper finds that import food price shocks strongly increase the likelihood of socio-political instability. This effect is greater in countries with lower levels of private credit and income per capita. On the other hand, while remittances seem to dampen the adverse effect of import food price shocks on socio-political instability in almost all countries, the mitigating role of fiscal policy is significant only in countries with low-levels of private credit.
本文采用涵盖1980-2012年期间数据的101个低收入和中等收入国家的面板,应用处理内质性问题的各种计量经济学方法,在考虑财政政策和汇款后,评估粮食价格冲击对社会政治不稳定的影响。它侧重于进口价格,以反映进口国/净购买国家庭对粮食价格冲击的脆弱性。本文发现,进口食品价格冲击极大地增加了社会政治不稳定的可能性。在私人信贷和人均收入水平较低的国家,这种影响更大。另一方面,虽然汇款似乎在几乎所有国家都能减轻进口粮食价格冲击对社会政治不稳定的不利影响,但财政政策的缓解作用只有在私人信贷水平较低的国家才显着。

An essential element of the work of the Fund is to monitor and forecast international trade. This paper uses SWIFT messages on letters of credit, together with crude oil prices and new export orders of manufacturing Purchasing Managers’ Index (PMI), to improve the short-term forecast of international trade. A horse race between linear regressions and machine-learning algorithms for the world and 40 large economies shows that forecasts based on linear regressions often outperform those based on machine-learning algorithms, confirming the linear relationship between trade and its financing through letters of credit.
基金组织工作的一项基本内容是监测和预测国际贸易。本文利用信用证上的SWIFT电文,结合原油价格和制造业新出口订单采购经理指数(PMI),改进对国际贸易的短期预测。线性回归和机器学习算法在全球和40个大型经济体之间的竞赛表明,基于线性回归的预测往往优于基于机器学习算法的预测,这证实了贸易与其通过信用证融资之间的线性关系。

We develop an integrated epidemiological-macroeconomic model to analyze the interplay between the COVID-19 outbreak and economic activity, as a tool for capacity building purposes. We illustrate a workhorse framework that combines a rich epidemiological model with an economic block to shed light on the tradeoffs between saving lives and preserving economic outcomes under various mitigation policies and scenarios calibrated for emerging market and developing economies. In our benchmark setup, we link the effective contact frequency and labor supply decisions to the current state of the disease progression, allowing for relevant behavioral responses that introduce multiple feedback channels. We showcase the effects of various “smart” mitigation measures, e.g. improved quarantine capacity or targeted labor market restrictions, to alleviate the tradeoffs between health-related outcomes and economic activity, including in response to a second infection wave. The discovery of treatment or vaccine, and the possibility of temporary immunity for the recovered individuals are also considered. The model is further extended to a multisector framework to analyze the sectoral allocation effects of the COVID-19 shock.
我们开发了一个流行病学-宏观经济综合模型,分析COVID-19疫情与经济活动之间的相互作用,作为能力建设的工具。我们展示了一个将丰富的流行病学模型与经济块相结合的工作框架,以阐明在针对新兴市场和发展中经济体校准的各种缓解政策和情景下拯救生命和保持经济成果之间的权衡。在我们的基准设置中,我们将有效接触频率和劳动力供应决策与疾病进展的当前状态联系起来,允许引入多个反馈渠道的相关行为反应。我们展示了各种“智能”缓解措施的效果,例如改善检疫能力或有针对性的劳动力市场限制,以减轻与健康有关的结果与经济活动之间的权衡,包括应对第二波感染浪潮。还考虑了治疗方法或疫苗的发现,以及康复个体暂时免疫的可能性。该模型进一步扩展到一个多部门框架,以分析COVID-19冲击对部门配置的影响。

The model is further extended to a multisector framework to analyze the sectoral allocation effects of the COVID-19 shock.","PeriodicalId":14326,"journal":{"name":"International Monetary Fund (IMF) Research Paper Series","volume":"181 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83451546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study the inflation process in India, focusing on the periods before and after the adoption of flexible inflation-forecast targeting (FIT) in India. Our analysis uses several approaches including standard Phillips curve estimation for headline and core inflation, an examination of the sensitivity of medium-term inflation expectations to inflation surprises, and the properties of convergence between headline and core inflation. Results indicate an important role for domestic factors in driving the inflation process, and there is evidence that expectations have become more anchored since 2015. This result could be attributable to FIT adoption, or to persistently low food prices which dominate the post-FIT-adoption period. The policy implications of these structural changes in the inflation process are investigated using a semi-structural model calibrated to the Indian economy.
本文研究了印度的通货膨胀过程,重点研究了印度采用弹性通货膨胀预测目标制(FIT)前后的通货膨胀过程。我们的分析使用了几种方法,包括对总体通胀和核心通胀的标准菲利普斯曲线估计,对中期通胀预期对通胀意外的敏感性的检验,以及总体通胀和核心通胀之间的收敛特性。结果表明,国内因素在推动通胀过程中发挥了重要作用,有证据表明,自2015年以来,通胀预期变得更加稳定。这一结果可归因于FIT的采用,也可归因于在FIT采用后占主导地位的持续低粮价。在通货膨胀过程中,这些结构性变化的政策含义是使用校准到印度经济的半结构模型进行调查。
