This study investigates how the dependence structures between stock markets and economic factors have changed during the COVID-19 pandemic using the dynamic model averaging approach. A series of economic factors such as commodity markets, cryptocurrency, monetary policy, international capital flows, and market uncertainty indices are considered. We find that the importance of economic variables and the sign and size of their coefficients are significantly different from those before the COVID-19 pandemic. The stock markets are most influenced by economic factors during the COVID-19 outbreak. 相似文献

This study investigates the relationships between challenge and hindrance stressors and hotel employees’ interpersonal citizenship behaviors (ICB). The study also tests the moderating role of hotel employees’ psychological capital (PsyCap) on the aforementioned relationships. Data were collected from 213 U.S. hotel frontline employees. The results showed that both challenge and hindrance stress had a negative relationship with ICB. PsyCap was found to moderate both relationships. Implications for hospitality researchers and industry practitioners are discussed along with the limitations and suggested avenues for future research. 相似文献

There is anecdotal evidence suggesting that those losing from globalization influence policy makers to decrease the openness of their countries to globalization, as evidenced by signing international trade and investment agreements. Surprisingly, this influence has never been examined empirically. This study provides novel empirical evidence demonstrating that greater within-country inequality, our proxy for 'perceived losses' from globalization, decreases countries' propensity to sign regional trade and investment agreements. Our findings support the argument that the existence of 'losers' from globalization can be detrimental for continued globalization. To the best of our knowledge, this is the first extensive econometric empirical evidence of the influence of within-country inequality on countries' willingness to sign international trade and investment agreements, as means to increase their global economic integration. 相似文献

本文通过在一般均衡模型中引入银行部门,考察了金融发展对企业创新和经济增长的影响。基于模型的理论分析表明,在均衡状态下,金融发展可以提高经济中储蓄向投资转化的效率、缓解信息不对称,有效降低了研发部门的外部融资成本,从而促进企业增加研发投入,并推动经济实现更高速的增长。在此基础上,本文以中国31个省份2008—2016年的面板数据对上述结论进行了实证检验,相关结果表明:(1)金融发展对企业研发投入具有显著的促进效应;(2)在工业化程度、外商投资水平较高的地区以及政府支出水平较低、人才资源相对短缺的地区,金融发展的促进作用更加明显;(3)企业研发创新可以有效推动经济增长,且在金融支持实体经济中发挥了重要的中介作用。本文的理论和实证分析揭示了“金融发展—企业创新—经济增长”的内生性传导机理及其在中国的体现,从而为金融支持创新型经济增长的改革逻辑奠定了初步的理论和经验基础。 相似文献

区域协调发展不仅受到资本积累数量的影响,更受到资本匹配质量的制约。在拓展MRW模型的基础上,理论分析“实物资本-人力资本-社会资本”最优匹配存在性与高效经济增长的关系,进一步构建资本匹配程度与匹配质量通过创新力培育实现落后地区经济赶超,进而影响区域协调发展能力的传导路径,并利用中国省级面板数据进行实证检验。结果表明,实物资本、人力资本与社会资本存量之间存在最优比例关系,且资本匹配质量主要通过创新力培育影响区域协调发展水平;资本匹配整体上有利于区域协调发展,东部地区资本匹配度对区域协调发展的促进作用高于中部地区、西部地区;机制检验发现,资本匹配通过组织创新效应实现区域协调发展的解释程度最大,其次为技术创新效应,最后是产业创新效应。 相似文献

发明人的创新活动嵌入在合作创新网络中。基于社会资本视角,从结构资本和认知资本两个维度辨识并定义4类发明人角色,包括“明星”、“纽带”、“平庸”和“活跃”发明人。以人工智能领域在德温特专利数据库(DII)授权的专利数据为样本,运用负二项模型,对4类发明人的二元创新能力进行实证对比分析。结果表明,不同角色发明人的二元创新能力显著不同。其中,“明星”发明人的二元创新能力最高,“平庸”发明人的二元创新能力最低,“活跃”发明人的二元创新能力高于“纽带”发明人,即认知资本对二元创新的影响大于结构资本。结论对提升发明人二元创新能力具有重要参考价值。 相似文献

This paper studies investment dynamics in Chinese manufacturing firms. The analysis estimates capital adjustment costs and uncovers capital distortion in state and non-state firms. There is strong evidence of quadratic adjustment cost and distortion in capital price for both types of firms. The capital distortion is a major source of capital misallocation in Chinese firms. Completely removing the distortion would increase aggregate total factor productivity (TFP) by 18–29%. 相似文献

This paper examines the interplays among studying abroad, return migration and capital accumulation, in a dynamic general equilibrium model featuring heterogeneous ability. Households invest in education and make two migration decisions: whether to study abroad and subsequently whether to return home. The model predicts that the highest, middle and lowest-ability people choose respectively permanent migration, return migration and no migration. More interestingly, we find a novel migration cycle: returnees bring back learned-knowledge and over time, capital accumulates, attracting more return migration. Further, the usual “brain drain” in the literature can be turned into “brain gain”, by providing a subsidy to studying abroad and returning home. 相似文献

Prior studies using pre-crisis data concluded that microfinance institutions are resilient to economic crises. However, some recent studies indicate that the microfinance sector is becoming part of the global financial system and microfinance lending activities are now vulnerable to economic and financial crises. Capital being a key resource to support lending, this paper analyzes the cyclical behaviour of capital ratio using an international sample of microfinance institutions from 2001 to 2014. We uncover a negative relationship between their capital-to-assets ratios and business cycle indicators. This relationship mainly concerns regulated institutions, comprised mostly of profit-oriented MFIs, and is driven by both asset-side and capital level adjustments. We identify the lending channel (loan-to-assets ratio) as the main mechanism to explain these cyclical variations. Our findings are consistent with the “procyclicality” of capital regulation documented extensively in the banking literature. Hence, macro-prudential regulation for MFIs should target regulated and profit-oriented MFIs. 相似文献

Land resources do not flow directly but can be allocated as “embodied land” in goods and services during economic globalization. The term “embodied arable land” can help link local land allocation strategies to the global and national supply chains and trade activities, and suggest new lens in optimizing arable land allocation. China is facing a serious arable land shortage, especially in municipal administrative areas. Based on the nested input-output analysis (Nested IOA), this work takes Shanghai as an example, exploring the allocation of direct and embodied arable land of an urban economy within the process of economic globalization. The amount of embodied arable land associated with Shanghai economy is 6.09 Mha, broken down into local arable land use (0.20 Mha), domestic inflows (3.20 Mha) and foreign inflows (2.69 Mha). This area supports local final demand (4.32 Mha), domestic outflows (1.24 Mha) and foreign outflows (0.53 Mha). Land-related imbalances emerge in the study, namely the economy’s demand versus the city’s size, the arable land demand versus supply, and embodied arable land inflows versus outflows. Regarding the role of the urban economy in allocation of global arable land under economic globalization, on the one hand, Shanghai has intensively involved with a large amount of embodied foreign arable land resources, and has been heavy dependent on foreign embodied arable land; On the other hand, there is still large potential for Shanghai to take the opportunity of economic globalization for an optimal allocation of direct and embodied arable land. Policy suggestions on taking the opportunity of economic globalization for an optimal allocation of direct and embodied arable land are put forward. 相似文献
