This paper uses 2018 data as a benchmark to build a numerical 26-country global general equilibrium model with trade cost and an endogenous trade imbalance structure. We assume that COVID-19 will increase the trade cost between countries and decrease labor supply in production. We use China’s trade data from January to April in 2020 to calibrate the influence level parameters and then simulate the trade effects of COVID-19 in China, the EU, the US, and the world. Our simulation results find that all countries’ trade and exports will be significantly hurt by the pandemic. Due to the trade diversion effect and the price growth effect, some countries will see an increase in import trade. Comparatively, the pandemic has the most negative impact on global trade, followed by the EU, the US, and China. As the pandemic deepens, the negative impact on trade will increase. The worldwide pandemic has the most significant impact on US trade, with an effect about 1.5 times that of the average world effect. 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

This paper proposes a susceptible-infected-removed dynamic stochastic general equilibrium (SIR-DSGE) model to assess the macroeconomic impact of the recent COVID-19 outbreak. The parameters of the SIR setting are calibrated to COVID-19 data from China. Using the model, we illustrate how the pandemic could result in consumption and output loss. We show that a combination of quarantine policy and random testing of the uninfected is effective in reducing the number of infected individuals and outperforms the alternative scenarios in which only one of the policies is implemented. Moreover, the economic impacts of both policies are evaluated. Compared with the decentralized equilibrium, we find that the Ramsey social planner allows output to decrease more substantially during the pandemic, in exchange for a faster economic recovery. 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

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

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

We examine how the COVID-19 contagion influences consumer expenditure patterns. We show that the consumption expenditure responses to the spread of the COVID-19 pandemic are significantly different between the older and younger generations. We find that older adults spend less than the younger generation by at least 5% during the pandemic. In fact, those aged above 60 significantly decrease their spending even on food and drink products by 13%. We also find that older adults forgo shopping in favor of the younger generation. These responses might be due to the fear of COVID-19 infection (Immordino et al., 2022). 相似文献

文章以中老年人参与志愿服务为例,基于2013-2015年中国健康与养老追踪调查数据,采用有序Logit、OLS、PSM-DID等方法,尝试解答助人会让人变得更幸福以及助人会对不同年龄群体幸福感产生差异吗等问题。研究结果表明：第一,中老年人参与志愿服务有助于提升幸福感水平,且在考虑到内生性问题情况下,该结论仍成立;第二,进行分样本讨论发现,这种影响存在年龄差异。具体而言,老年人参与志愿服务对幸福感有显著提升作用,但对中年人影响并不显著;第三,经济因素并不对志愿服务与幸福感之间的关系起调节作用;第四,通过中介效应检验发现,中老年人参与志愿服务通过提升积极情绪实现,而消极情绪则起遮掩效应。文章的研究意义在于,理论上,梳理了国内外关于中老年人志愿者服务对幸福感影响的文献,丰富了当前我国中老年人志愿服务参与和幸福感关系的理论和经验研究;实践上,为推进我国中老年人志愿服务参与、保障幸福老年生活及构建互助的社会网络支持体系提供了一定的建议与启示。 相似文献

We examine the effectiveness of fiscal and monetary policy in mitigating the impact of COVID-19 in India using the NK-DSGE framework. In terms of policy effectiveness, our findings imply that expansionary monetary policy is effective in reviving economic growth both from the demand side and supply side. In contrast, expansionary fiscal policy is effective only from the supply side. Our findings recommend the implementation of optimal policy mix in a coordinated and staggered framework for effective mitigation of ill-effects of the COVID-19, such as reviving employment and capacity utilization to its pre-pandemic level with minimal inflationary effects. 相似文献

This paper investigates the sleeplessness in Chinese cities during the coronavirus disease 2019 (COVID-19) pandemic. We provide first evidence of a link from daily COVID-19 cases resulting in sleep loss in a panel of Chinese cities. We use Wuhan, which was the first city to be completely locked down, as basis to present the result that sleeplessness has become a considerably serious issue owing to the COVID-19 pandemic. In using the intervention policy of various cities as exogenous shocks, we find that lockdown policies significantly increase the sleeplessness level of Chinese cities. In addition, the severity of COVID-19 pandemic significantly exacerbates the negative effect of lockdown policies on sleep quality in the city. Overall, this study indicates that policy makers should pay more attention to public mental health when citizens recover from COIVD-19 by investigating the unintended consequences of COVID-19 on sleeplessness level of cities. 相似文献

COVID-19 pandemic has substantially altered socioeconomic conditions around the world. While numerous existing studies analyze the impact of the COVID-19 pandemic among developed states, little is known about its effects on people’s lives and social discrepancies in emerging economies. To this end, we empirically analyze the 2020 Indonesian Labor Force Survey data, hypothesizing that COVID-19 has given idiosyncratic risks and impacts on people by gender, age, education, occupation and regions. We find that income loss and job loss are prominent among males, younger and less educated people as well as among self-employed and part-time non-agricultural workers. These tendencies are not pronounced for people enjoying high income and mobility, but tend to be evident for urban residents and those having dependents. Notably, self-employed people have the highest risk of losing income, while part-time urban workers face the highest probability of losing their jobs. The propensity score matching method also demonstrates that these losses are most evident for the regions susceptible to COVID-19. Overall, we suggest that socioeconomically disadvantaged groups require additional support to strengthen their resilience in the face of exogenous shocks, such as the one caused by the global coronavirus pandemic. 相似文献

A computable general equilibrium model linked to a microsimulation model is applied to assess the potential short-term effects on the South African economy of the ongoing COVID-19 pandemic. With a particular focus on distributional outcomes, two simulations are run, a mild and a severe scenario. The findings show significant evidence of decline in economic growth and employment, with the decline harsher for the severe scenario. The microeconomic results show that the pandemic moves the income distribution curve such that more households fall under the poverty line while at the same time, inequality declines. The latter result is driven by the disproportionate decline in incomes of richer households while the poorest of the poor are cushioned by government social grants that are kept intact during the pandemic. The COVID-19 pandemic is still unfolding and its economic modelling as well as the data used to operationalise the model will need to be updated and improved upon as more information about the disease and the economy becomes available. 相似文献

Using nationally representative income and expenditure data from South Korea, we show that single-person households suffered a much greater decrease in household income and expenditure compared to multi-persons households during the COVID-19 pandemic in 2020. Negative effects on income were largest for the single-person households in ages 50—64, mostly driven by decreases in earned income rather than business income. There was no corresponding decrease in consumption expenditures, however, other than on transportation expenditure for young men. Notably, there were significant decreases in non-consumption expenditures that are related to formal and informal consumption-smoothing mechanisms, such as spending on insurances, pensions, and household transfers. Our findings highlight the disproportionately negative effects of the COVID-19 pandemic on the middle-aged single-person households. With reduced spending on consumption-smoothing mechanisms, this group is likely to be even more vulnerable to negative income shocks in the future. 相似文献
