We examine the role of the vaccine initiation rate in mitigating the international stock market volatility during COVID-19. Our findings reflect that the positive effect of the vaccine initiation rate assists in stabilizing the international stock markets. This possible effect is stronger for developed markets, and countries with the vaccine initiation rate are above its overall average. The mass vaccinations signal a lower probability of stringent government responses to the pandemic. The low level of trust in governments’ actions makes the investors hold compliance fears and doubt that the negative effects of COVID-19 may be longer, especially for emerging markets.
我们研究了疫苗启动率在缓解COVID-19期间国际股市波动中的作用。我们的研究结果反映出疫苗启动率的积极作用有助于稳定国际股票市场。这种可能的影响在发达市场更为明显,疫苗启动率高于其总体平均水平的国家。大规模疫苗接种表明,政府对大流行采取严格应对措施的可能性较低。对政府行为的信任度较低,使投资者对合规感到担忧,并怀疑COVID-19的负面影响可能会持续更长时间,特别是对新兴市场。

Carry Trade and Precautionary Saving of Foreign Currency Debt: Evidence from Korean Firms 套利交易与外币债务的预防性储蓄:来自韩国企业的证据
Pub Date : 2021-09-22 DOI: 10.2139/ssrn.3929036

Substantially increased global corporate debt in the past decade revives macro stability concerns of foreign currency liability in emerging countries. Due to data unavailability, there is limited understanding of how the debt proceeds are used. We empirically study the use of proceeds of debt issuance in different currencies using a rich firm-level dataset from Korea which provides information on the currency denomination of both assets and liabilities of firms. We establish six key empirical findings: 1) Consistent with a carry trade hypothesis, firms that issue foreign currency short-term loans increase local currency liquid assets. 2) Consistent with a precautionary saving hypothesis, firms that issue foreign currency loans, regardless of the maturity of loans, increase foreign currency liquid assets. 3) Consistent with the corporate finance pecking order prediction, firms that issue local currency loans reduce both local and foreign currency liquid assets and lower dividend payouts. 4) Investment decreases with short-term foreign currency debt but increases with other types of debt. 5) Stronger carry trade and precautionary saving behavior are observed when the interest rate differential and exchange rate volatility are high, respectively. 6) Sectors that are financially dependent or export exposed have shown a stronger carry trade and precautionary saving behavior.
过去10年全球企业债务大幅增加,重新引发了对新兴国家外币负债宏观稳定的担忧。由于无法获得数据,对债务收益如何使用的了解有限。我们使用来自韩国的丰富的公司层面数据集对不同货币的债务发行收益的使用进行了实证研究,该数据集提供了公司资产和负债的货币面额信息。我们建立了六个关键的实证发现:1)与套利交易假设一致,发行外币短期贷款的公司增加了本币流动资产。2)与预防性储蓄假设相一致,发行外币贷款的公司,无论贷款期限如何,都会增加外币流动资产。3)与企业融资优先顺序预测一致,发放本币贷款的企业同时减少了本币和外币流动资产,并降低了派息。4)投资随着短期外币债务而减少,但随着其他类型债务的增加而增加。5)利差和汇率波动较大时,套利交易和预防性储蓄行为较强。6)金融依赖或出口敞口的行业表现出更强的套息交易和预防性储蓄行为。

Barriers to Creative Destruction: Large Firms and Non-Productive Strategies 创造性破坏的障碍:大公司和非生产性战略
Pub Date : 2021-09-19 DOI: 10.2139/ssrn.3927528
S. Baslandze
This chapter reviews recent empirical evidence on large firms and non-productive strategies that hinder creative destruction and reallocation. The focus is on three types of non-productive strategies: political connections, non-productive patenting, and anti-competitive acquisitions. Across different contexts using granular micro data sets, we overwhelmingly see that as firms gain market shares, they rely more on non-productive strategies but reduce their productive, innovation-based strategies. I discuss theoretical channels, aggregate implications, and potentials for some policies.
本章回顾了最近关于大公司和阻碍创造性破坏和再分配的非生产性战略的经验证据。重点是三种非生产性战略:政治关系、非生产性专利和反竞争收购。在不同的背景下使用颗粒微观数据集,我们压倒性地看到,随着企业获得市场份额,他们更多地依赖于非生产性战略,但减少了他们的生产性创新战略。我讨论了一些政策的理论渠道、总体影响和潜力。

Employee Views of Leveraged Buy-Out Transactions 员工对杠杆收购交易的看法
Pub Date : 2021-09-18 DOI: 10.2139/ssrn.3926300
M. Lambert, Nicolas Moreno, Ludovic Phalippou, Alexandre Scivoletto
A large sample of employee reviews shows a decline in satisfaction after a Leveraged Buy-Out (LBO), but with significant heterogeneity. The key driver is the previous ownership structure. For Private-to-Private transactions, dissatisfaction is concentrated in non-management employees and comes mostly from how management treats them. In Public-to-Private transactions, the dissatisfaction is stronger, multi-faceted, and present for all employees, including management. Industry and Private Equity sponsor fixed effects are significant, but second order. Other ownership changes (M&A, IPO) trigger less dissatisfaction.
一个大样本的员工评价显示,在杠杆收购(LBO)后,满意度下降,但具有显著的异质性。关键的驱动因素是之前的所有权结构。对于Private-to-Private交易,不满主要集中在非管理层员工身上,主要来自于管理层对待他们的方式。在公私交易中,这种不满更强烈,是多方面的,并且存在于所有员工中,包括管理层。行业和私募股权发起人的固定效应显著,但居于次要地位。其他所有权变更(并购、IPO)引发的不满较少。

Fund Flows, Performance, and Exit Under Dynamic Unobservable Managing Ability 动态不可观察管理能力下的资金流动、绩效与退出
Pub Date : 2021-09-16 DOI: 10.2139/ssrn.3719953

. We introduce continuous-time learning models of dynamic unobservable fund manager abilities under a nonlinear framework, with risk-neutral or risk-averse investors. In equilibrium, sensitivities of inferred manager abilities to fund returns’ innovation shocks are time nonmonotonic, inducing time-nonmonotonic flow-performance sensitivities and convexities. Funds’ exit probabilities change with time and fund sizes at any fund age. Our empirical evidence of nonmonotonic flow-performance sensitivities and convexities, and old funds’ increasing exit probability with fund age support our nonlinear framework, which current linear frameworks cannot explain. We also offer insights into the current empirical controversy of whether flow-performance relations are linear or convex.
. 我们在非线性框架下引入了风险中性或风险厌恶投资者的动态不可观察基金经理能力的连续时间学习模型。在均衡状态下,推断经理人能力对基金收益创新冲击的敏感性是时间非单调的,从而产生时间非单调的流动绩效敏感性和凸性。基金的退出概率随时间和基金规模而变化。我们的非单调流动绩效敏感性和凸性以及老基金退出概率随基金年龄增加的经验证据支持了我们的非线性框架,这是当前线性框架无法解释的。我们也提供见解到当前的经验争议是否流动性能关系是线性或凸。

Everywhere Differentiable Continuums, Mathematical Spaces, and Axioms: Modeling of Financial Phenomena 处处可微连续体、数学空间和公理:金融现象的建模
Pub Date : 2021-09-12 DOI: 10.2139/ssrn.3861264
Oghenovo A. Obrimah
Formal theoretical proofs show modeling of stock returns on `everywhere differentiable' continuums always is inappropriate to modeling of rational expectations equilibriums (REE). Simultaneously, modeling of stock returns in discrete time always is robust to modeling of each of REE, or feasibility of deviations from REE. In stated respect, modeling in discrete time results in dichotomous sufficiency conditions for each of conformance with, or deviation of investors' priors from REE. Bane of modeling in continuous time is non-dichotomization of connectedness property of stock prices from evolution of stock prices, a contradiction to the norm that connectedness properties be independent of specific elements that are located in topological spaces. In aggregate, while modeling in continuous time induces positive relations between risk (volatility) and returns, contrary to rational expectations, it is relatively low realizations for volatility that have higher risk of generation of negative returns.
正式的理论证明表明,在“处处可微”连续体上建立股票收益模型总是不适合建立理性期望均衡模型。同时,离散时间股票收益的建模对于每一个REE的建模或偏离REE的可行性都具有鲁棒性。在声明的方面,离散时间的建模导致投资者的先验与REE的一致性或偏差的二分类充分性条件。连续时间建模的缺点是股票价格的连通性不能从股票价格的演变中二分化,这与连通性属性独立于位于拓扑空间中的特定元素的规范相矛盾。总的来说,虽然连续时间的建模可以得出风险(波动率)与收益之间的正相关关系,但与理性预期相反,产生负收益的风险较高的波动率的实现相对较低。

Investment-Specific Technological Progress: The Perspective of Capital Owners 投资特异性技术进步:资本所有者的视角
Pub Date : 2021-09-11 DOI: 10.2139/ssrn.3941839
Yosuke Jin
This study highlights the importance of investment-specific technological (IST) progress in affecting the business cycle, which is identified by properly specifying shock propagation mechanisms. IST progress differentiates the value of investment goods across different vintages, which raises payouts from new investments while inducing capital losses of older investment goods. I develop a DSGE model that focuses on asset valuation by capital owners, considering their net wealth. The study shows that an IST shock raises investment and output significantly in contrast to the existing studies that estimate DSGE models. When associated with other shocks related to financial market mechanisms, the IST shock accounts for approximately 35% of output fluctuations. These findings are similar to those reported in the studies that adopted less stringent shock propagation mechanisms such as structural VAR models. These findings can provide a way to reconcile the significantly different results reported in the literature until date.
本研究强调了投资特定技术(IST)进步在影响商业周期中的重要性,这是通过适当指定冲击传播机制来确定的。IST的进步区分了不同年份投资商品的价值,这提高了新投资的收益,同时导致了旧投资商品的资本损失。我开发了一个DSGE模型,关注资本所有者的资产估值,考虑他们的净财富。该研究表明,与估计DSGE模型的现有研究相比,IST冲击显著提高了投资和产出。当与金融市场机制相关的其他冲击联系在一起时,技术创新冲击约占产出波动的35%。这些发现与采用不太严格的冲击传播机制(如结构VAR模型)的研究报告相似。这些发现可以提供一种方法来调和迄今为止在文献中报道的显著不同的结果。

Investors’ Perception of Business Group Membership during An Economic Crisis: Evidence from the COVID-19 Pandemic 经济危机期间投资者对企业集团成员资格的看法:来自COVID-19大流行的证据
Pub Date : 2021-09-07 DOI: 10.2139/ssrn.3889505
Romain Ducret
This paper examines how investors perceive business group membership in Korea during the COVID-19 pandemic. Evidence of a time-varying and heterogeneous value of affiliation emerges from stock price performance analysis. I find that investors discount business group affiliation during a market collapse, but are willing to pay a premium for affiliation during market recovery. Overall, this pattern is more pronounced for financially weak affiliates and large business groups. Results also show that business group membership alleviates investors’ concerns regarding financial flexibility highlighting the role of internal capital markets as a substitute to external finance.
本文分析了在新冠疫情(COVID-19)期间,投资者如何看待韩国企业团体会员制度。在股票价格表现分析中出现了时变和异质性价值关联的证据。我发现投资者在市场崩溃时对企业集团的隶属关系不感兴趣,但在市场复苏时却愿意为隶属关系支付溢价。总的来说,这种模式在财务状况不佳的子公司和大型企业集团中更为明显。结果还表明,企业集团成员减轻了投资者对财务灵活性的担忧,突出了内部资本市场作为外部融资替代品的作用。

Repricing Avalanches in the Billion-Prices Data 十亿价格数据中的重新定价雪崩
Pub Date : 2021-09-01 DOI: 10.2139/ssrn.3907149
Laura Leal, Haaris Mateen, Makoto Nirei, J. Scheinkman
Nirei and Scheinkman (2021) proposed an equilibrium model of price adjustments with menu-costs with a finite number of firms and derived a "reproduction number" for repricing and a limit functional form for the distribution of the number of simultaneously price-adjusting firms. We show that the distribution of price-changes in data from the Billion Prices Project is well fitted by this functional form and exhibits a reproduction number that is close to unity, indicating that complementarity in price-changes plays a major role in repricings.
Nirei和Scheinkman(2021)提出了有限企业数量下具有菜单成本的价格调整均衡模型,并推导出了重新定价的“再生产数”和同时进行价格调整的企业数量分布的极限函数形式。我们发现,十亿价格项目数据的价格变化分布很好地拟合了这种函数形式,并表现出接近于一的再现数,表明价格变化的互补性在再定价中起主要作用。

Sri Lanka's Economy Plummeting under the Influence of COVID-19 Epidemic 受新冠疫情影响,斯里兰卡经济急剧下滑
Pub Date : 2021-08-30 DOI: 10.2139/ssrn.3914259

The COVID-19 epidemic, declared by the World health Organization as a global epidemic on 11th of March 2020, is now not only a global health crisis but also a global economic and financial crisis. In this situation Sri Lanka’s all major sources of income are at high risk. This research is focused the economic impact of COVID-19 on Sri Lankan economy specific the three major components of the economy in Agriculture, Industry & Service sector. Those are contributed their share to the GDP at current prices by 7.3%, 28.4%, 58.3% respectively in the first quarter of 2020.As a result of the COVID-19 outbreak many sectors in the economy was in deep decline. Therefore GDP estimates of the first quarter of 2020, have reported in Agriculture, & Industrial activities by 5.6% and 7.8% respectively. Although during the first Quarter of 2020 services sector activities have been continued further. Also the severe downturn in the tourism industry, which has been instrumental in boosting Sri Lanka’s foreign reserves, has been a major challenge at Present. The Sri Lanka Rupee is depreciating rapidly due to the depreciation of foreign reserves. In such a situation Sri Lanka is facing a serious challenge of sustaining economic growth by spending large amounts of foreign exchange on vaccinations and PCR & RAT tests required for virus control.
新冠肺炎疫情于2020年3月11日被世界卫生组织宣布为全球流行病,现在不仅是一场全球卫生危机,也是一场全球经济和金融危机。在这种情况下,斯里兰卡的所有主要收入来源都处于高风险之中。本研究的重点是COVID-19对斯里兰卡经济的经济影响,具体包括农业、工业和服务业经济的三个主要组成部分。2020年第一季度,按现价计算,这些行业对GDP的贡献率分别为7.3%、28.4%和58.3%。由于新冠肺炎疫情的爆发,经济中的许多部门都陷入了严重衰退。因此,农业和工业活动报告的2020年第一季度GDP估计分别为5.6%和7.8%。尽管在2020年第一季度,服务业的活动仍在继续。此外,旅游业的严重衰退一直是增加斯里兰卡外汇储备的重要因素,目前也是一个重大挑战。由于外汇储备的贬值,斯里兰卡卢比正在迅速贬值。在这种情况下,斯里兰卡面临着一项严峻的挑战,即通过将大量外汇用于疫苗接种和病毒控制所需的聚合酶链反应和鼠式反应检测来维持经济增长。
