This study investigates the sources of Japanese business fluctuations since the 1990s, taking into account both external shocks (e.g., risk premium and foreign demand shocks) and domestic supply and demand shocks. We use the sign-restricted VAR model based on the theoretical model to identify these shocks. The presented results show that approximately 30–50% of the forecast error variances in output can be explained by external shocks. Further, we demonstrate that supply shock is the main influencing factor in Japanese business fluctuations throughout the sample period and that the role of external shocks has been growing in the post-Lehman period, including the effect of the Great East Japan Earthquake.  相似文献

This study examines how economic and social activities in Asia were affected by the COVID-19 pandemic, using the emissions of various air pollutants as representative measures of those activities. Our review of emissions data suggests that the amount of air pollutants emitted decreased in most subnational regions from 2019 to 2020. We also determined that economic and social activities have restarted in some regions in many countries. Moreover, we conduct regression analyses to identify the types of regions that restarted earlier. Regional characteristics are distinguished by employing a remotely sensed land cover dataset and OpenStreetMap. Results reveal that in the case of the Association of Southeast Asian Nations (ASEAN) forerunners, economic and social activities in cropland, industrial estates, accommodations, restaurants, education, and public services have not yet returned to previous levels.  相似文献

The COVID-19 outbreak had a significant impact on business cash flows and investment activities. This paper examined the COVID-19 impact on Chinese business investment in 3326 A-share listed quarterly financial reports, from which it was found that the negative relationship was more pronounced in the large, eastern Chinese state-owned firms. Using a propensity score matching method and difference-in-differences estimation, corporate financial flexibility was also examined, with the results indicating that high cash flexibility provided a buffer that allowed firms to better deal with adverse external shocks as the firms that had high cash flexibility were able to significantly increase their investments after the COVID-19 outbreak. Various robustness tests were conducted, all of which verified the robustness of the results. Overall, the empirical results provided evidence that the COVID-19 pandemic in China had a negative impact on Chinese listed firms, and verified the vital role of flexible financial reserves for firm survival and development during crises.  相似文献

以海南省旅游统计数据为基础,利用ARIMA模型,并结合新冠肺炎确诊人数进行预测分析。结果表明,海南省游客流量和旅游收入在新冠疫情下依然可以很大程度保持原有的增长趋势和季节性波动规律,但两组数据表现略有不同。新冠肺炎疫情对海南省旅游统计数据的影响体现在两个方面,一方面是新冠肺炎疫情严重程度与旅游统计数据存在明显此消彼长的关系,另一方面是新冠肺炎疫情主要对旅游统计数据中的游客流量产生了较大影响。可以得出政策启示:政府要做好疫情防控和让民众对旅游业持有信心,要随着疫情发展弹性放开或收紧旅游业,还要对需求侧进行扶持和对供给侧进行创新。  相似文献

The global COVID-19 pandemic has generated serious challenges for the world economy, including cross-border foreign direct investment (FDI). China’s inward FDI (IFDI) and outward FDI (OFDI) are also facing unprecedented risks and challenges. This paper first clarifies the timelines of the pandemic evolving in China, the US, and the rest of the world. It then reflects on China’s past development process of IFDI and OFDI, noting the growth of IFDI and highlighting the risks and challenges for OFDI during and after the pandemic. Empirical evidence for the impact of COVID-19 on FDI is set out. Policy recommendations are then made regarding China’s latest development strategy using the so-called dual circulation to sustain its economic growth with respect to cross-border FDI.  相似文献

本文采用基于中国经济的DSGE模型,模拟在技术和政策的外生冲击下,建立统一碳排放市场对总产出、环境质量和CER实际价格产生的影响。分析结果表明,在政府制定好CER审核标准的前提下,短期至中期,建立统一碳排放市场具有减小总产出波动、提高环境质量以及减小CER实际价格波动的作用。而在长期,建立统一碳排放市场并不会对总产出和CER实际价格产生明显影响,却对环境有改善的作用。同时建立统一碳排放市场将会:使得财政政策的效果与未建立统一碳排放市场时的效果相反;要求政府对CER审核标准的定制更加谨慎,以应对清洁型技术可能带来的部分不利影响;对货币政策效果影响不明显。  相似文献

The COVID-19 pandemic led many governments to implement lockdown regulations to curb the spread of the virus. Though lockdowns do minimise the physical damage caused by the virus, there may also be substantial damage to population well-being. Using a pooled data set, we analyse the relationship between a mandatory lockdown and happiness in three diverse countries: South Africa, New Zealand and Australia. These countries differ amongst others in terms of lockdown regulations and duration. The primary aim is to determine, whether a lockdown is negatively associated with happiness, notwithstanding the characteristics of a country or the strictness of the lockdown regulations. Second, we compare the effect size of the lockdown on happiness between these countries. We use Difference-in-Difference estimations to determine the association between lockdown and happiness and a Least Squares Dummy Variable estimation to study the heterogeneity in the effect size of the lockdown by country. Our results show that a lockdown is associated with a decline in happiness, regardless of the characteristics of the country or the type and duration of its lockdown regulations. Furthermore, the effect size differs between countries in the sense that the more stringent the stay-at-home regulations are, the greater it seems to be.  相似文献

The COVID-19 pandemic severely disrupted international trade, leading countries to grapple with product shortages and firms to experience major supply chain issues. These challenges increased production costs and significantly contributed to lower trade and higher inflation. In this paper, we examine the impact of COVID-19 on Chinese trade through its two main trading partners: Japan and the US. By differentiating products by product type and processing status, we find evidence that products in the middle of the global supply chain were most affected by the pandemic and that the severity of the shock depends on the partner country’s role in the global supply chain. Additionally, we find that Chinese exports are more impacted than Chinese imports, regardless of processing status. These findings are largely consistent with economic theory. Understanding that the effects of global shocks vary by product and country will help guide policies that minimize supply chain disruptions.  相似文献

COVID-19 has had an enormous effect on labor markets globally. Economic restrictions, notably strict border controls and lockdowns, have led many workers to lose their jobs and forced many migrants to return to their homes or change their migration plans. While adverse effects on labor mobility are expected, variations in the prevalence of COVID-19 and governmental responses to the pandemic across countries are likely to influence workers’ intentions to migrate in different ways. To understand the effects of pandemics on the international labor supply, we explore the impact of COVID-19 and the various economic restriction policies on job search behavior by considering cases from Southeast Asian countries using the difference-in-differences (DID) approach with data from Google Trends Index (GTI). We find that the search volume of queries related to the labor market dramatically increased over time following the outbreak of COVID-19. However, we do not observe any positive impact on the search volume related to emigration, regardless of the infection control measures in the host countries. Our results imply that the job insecurity increases after the imposition of lockdown in the respective countries. On the other hand, the expectation to migrate outside of the country, which requires preparation time and incurs high costs, does not seem to have increased in developing countries.  相似文献

本文建立了一个包含异质性家庭、企业、零售商、商业银行、中央银行等多部门的动态随机一般均衡模型。模型中企业以房地产抵押向银行借贷,普通家庭通过银行借款提前消费房地产,将房地产市场与银行体系引入模型,两者构成模型中经济波动传导的主体。我们模拟了各种冲击(包括房地产偏好、存款准备金率、通胀等)对宏观经济变量的动态影响,模拟的一些结果和现实中国经济反应非常一致。模拟结果表明:房地产需求的增加会在一定程度上引发经济衰退,影响经济最重要的变量是央行的存款准备金率和通胀冲击,银行体系将外生冲击分散传导,导致经济主体在冲击下形成其不同经济表现,在我国,银行体系是我国经济波动不可忽视的传导途径。  相似文献

货币政策预期管理对于我国防范金融风险、稳定经济增长有重要的作用.通过构建含有托宾Q的新凯恩斯DSGE模型,在不同货币政策规则下引入预期冲击,运用贝叶斯方法对模型进行估计并分析货币政策未预期冲击和预期冲击对宏观经济变量的影响.政策实验分析发现,经济系统受到货币政策预期冲击之后,各主要宏观经济变量产生了消息冲击驱动的经济周期波动,表明货币政策预期管理能够影响到宏观经济运行,经济主体预期在经济系统中能够起到一定传导作用.此外,相对于未预期的货币政策冲击,货币政策预期冲击对宏观经济变量的影响更为平缓,更能起到抵御资产价格巨幅震荡、平滑经济稳定运行的作用.因此,我国央行有必要加强货币政策预期管理,进一步完善货币政策预期管理机制.  相似文献

Fossil-fuel burning transportation methods significantly contribute to air pollution. During the COVID-19 pandemic, South Korea experienced a 10-20% decline in commuting flows, even without government-mandated stay-at-home orders. This paper quantifies the impact that decreased commuting flows have on PM2.5, PM10, NO2, CO, and SO2, using municipality level commuting data. We find that a 1% decrease in commuting flows decreases air pollutants by 0.08-0.17%, after controlling for seasonality and time-varying local production. The effect was higher in regions with high initial pollution, and people recognized air quality improvements. These results emphasize the importance of encouraging cleaner transportation methods after the pandemic.  相似文献

This paper employs a difference-in-differences strategy to examine the causal effect of exposure to the COVID-19 pandemic on interpersonal trust amidst zero-COVID policies in China. Using a nationally representative panel survey, we find that COVID-19 exposure leads to a decrease in the levels of generalized trust. We also show that the change in interpersonal trust varies across domains. Specifically, COVID-19 exposure significantly decreases trust in parents, neighbors, and local government officials, but has small and insignificant effects on trust in doctors, strangers, and Americans. Empirical tests suggest that changes in income and physical health status are not likely to be potential channels. We provide some evidence for the mechanism of deteriorated mental health status and pessimistic expectations.  相似文献
