We assess the conditional relationship in the time-frequency domain between the return on S&P 500 and confirmed cases and deaths by COVID-19 in Hubei, China, countries with record deaths and the world, for the period from January 29 to June 30, 2020. Methodologically, we follow Aguiar-Conraria et al. (2018), by using partial coherencies, phase-difference diagrams, and gains. We also perform a parametric test for Granger-causality in quantiles developed by Troster (2018). We find that short-term cycles of deaths in Italy in the first days of March, and soon afterwards, cycles of deaths in the world are able to lead out-of-phase US stock market. We find that low frequency cycles of the US market index in the first half of April are useful to anticipate in an anti-phasic way the cycles of deaths in the US. We also explore sectoral contagion, based on dissimilarities, Granger causality and partial coherencies between S&P sector indices. Our findings, such as the strategic role of the energy sector, which first reacted to the pandemic, or the evidence about predictability of the Telecom cycles, are useful to tell the history of the pass-through of this recent health crises across the sectors of the US economy. 相似文献

This paper uses data at the trading day frequency and the method of local projections to quantify the dynamic responses of U.S. airline stock prices to a COVID-19 shock. We show that airline stock prices decline immediately by 0.1 percentage point in response to a 1% COVID-19 shock. In addition, the effect of the shock persists beyond the day on which it occurs, with most airline stock prices falling by as much as 0.6 percentage points after fifteen days. This negative response of airline stock prices to a COVID-19 shock is not explained by a COVID-19-induced increase in airlines’ variable costs, but rather by a COVID-19-induced decrease in air travel, which, in turn decreases revenues, profitability, and stock prices of U.S. airlines. 相似文献

应对疫情的财政政策对财政自身的收支平衡产生很大的冲击,这更凸显了财政制度建设的重要性。本文认为,财政制度建设需要建立在以下六个认识基础上:国家需要与其经济发展阶段相匹配的财力;税收成本一般低于其他形式财政收入;税收第一位功能是筹集财政收入,而不是其他;通过国有企业支撑财政不是长久之计;提高财政透明度、加强财政预算审查是财政提质增效的最好办法;财政改革最终落脚到现代治理观念和方式的变革。 相似文献

This research aims to assess air travelers' concerns affected by the Coronavirus pandemic, expressed in the comments they wrote online. A sample of 639 comments written on the Italian National Consumer Union website and related to the airline industry was assessed through an automated sentiment analysis in this study. The achieved results showed that travelers' concerns were directed mainly towards compensations, cancellations, and COVID-19 and at the same time, they had mixed and unpredictable feelings. This element suggests that consumers may have understood that airline companies are facing unsustainable cash-flow and revenue situations. Moreover, all our hypotheses, grounded on existing literature, were refuted. Accordingly, we argue that the actual context prevents assessments based on previous assumptions, and studies related to the impact of COVID-19 need to be conducted anew. 相似文献

The travel, tourism and hospitality industries have been the worst affected of the world's major economic sectors during the COVID19 pandemic, which has had a devastating effect on both destinations and organisations. Drawing from a sample (N = 385) of adult permanent residents of Athens, Greece, the study examines the impact of COVID19 upon holiday intention. The chaordic systems are evaluated through the use of fuzzy-set Qualitative Comparative Analysis, whilst the study also used Necessary Condition Analysis for the calculation of the size effects of the examined conditions. The findings reveal two sufficient complex configurations leading to holiday intention: (i) holiday risks, and (ii) impact of COVID19. Based on the results, the article also offers a set of managerial implications. The contribution of the study is to both theoretical and methodological tourism domains. 相似文献

The coronavirus pandemic has had a devastating impact on the demand for air transport. One passenger segment that has received relatively little attention is ageing passengers (defined as aged 65+), in spite of the fact that this group has been disproportionately affected by COVID-19, and in recent years has been viewed as a potential growth market. Therefore, the aim of this brief paper is to analyse the attitudes of ageing passengers by assessing air travel plans in the next 12 months, examining the factors influencing future flying decisions, and investigating the impact of the coronavirus pandemic on perceived risks and experiences associated with flying. The findings show that over 60% of ageing passengers are planning to travel by air in the next 12 months, although the nature of their trips may change. Factors such as flexible ticket booking and quarantine rules do not appear to be key drivers affecting travel decisions and within the different stages of the air journey, getting to/from the airport is perceived as the safest stage. The findings suggest that there are various COVID-19 implications for airlines and airports serving this market segment, ranging from the use of self-service technology, the generation of commercial/ancillary revenues and the design of surface access policies. 相似文献

The study is based on a multi-year research conducted in three successive years (2019; 2020; 2021). Drawing from three samples (N = 507; 463; 488) it longitudinally examines the complexity and the derived chaordic systems of the impact of COVID-19 upon the purchasing intentions of adult Athenian holidaymakers by using fuzzy-set Qualitative Comparative Analysis. In doing so, it evaluates the simple conditions of impact of recession, destination selection, and price and quality risks, also progressing to a complementary examination through Necessary Condition Analysis. The findings generate three pathways (price-quality nexus; financial focus; destination orientation) leading to the same outcome (purchasing intentions), the hierarchy of which changed over time. They also highlight the impact of recession and quality risks as constant necessary conditions, and demonstrate the transformation over time of destination selection and price risks from influential to necessary. The contribution of the study lies in both the theoretical and methodological domains. 相似文献

COVID-19 has drawn renewed focus on the importance of resilience, both among practitioners and in academia, as companies struggle to cope with the rapid swings, changing patterns, and disruptions in supply and demand. This article identifies and delineates a way forward for companies to support resilience, particularly recognizing the wider communities they are nested in and the resources that exist there. To identify such productive resources, known as capitals, we provide a novel and actionable integrated capitals framework (ICF). ICF integrates 10 existing frameworks drawn from both practice and academia and is comprised of nine different forms of capital that businesses can leverage and contribute toward supporting resilience. We provide insights into how businesses can use this framework to achieve resilience through this useful, yet underutilized, path. 相似文献
