We explore high-frequency arbitrage activities on international cross-listed stocks and develop a methodology to study the effect of information latency in high-frequency trading. We derive statistical arbitrage bounds for a mean-reverting synthetic instrument engineered from cross-listed stock prices, and we propose a new strategy that takes advantage of price deviations outside these bounds. Market frictions such as trade costs, inventory control, and arbitrage risks are considered. The strategy is tested with cross-listed stocks involving three exchanges in Canada and the United States in 2019. The annual net profit with the limit order strategy is around US$6 million, whereas the market order version is not profitable because of the great interconnectedness between exchanges in our data.  相似文献

The panic buying behavior under public health emergencies will lead to many adverse consequences, such as material waste, price fluctuation and uneven distribution of epidemic prevention materials, which will pose a threat to the social stability and economic development. In this paper, we construct a tripartite game model to explore the strategic choices of the public, merchants and the government in order to effectively respond to the panic buying behavior in the epidemic. The results demonstrate that: (1) Eight evolutionary stable strategies emerge in the panic buying events. The worst scenario can be improved by adjusting some relevant parameters. (2) The probability of the public choosing the strategy of “not involving in panic buying” depends on the potential benefits and losses of snapping up, rather than the extent of price rising. (3) The probability of merchants choosing the strategy of “not bid up price” depends on the intangible benefits. (4) The probability of the government choosing the strategy of “active supervision” depends on the supervision costs and government credibility, rather than the amount of fines. In addition, strategic suggestions to mitigate panic buying behavior are put forward from the perspective of each stakeholder.  相似文献

While online retail sites succeed in reinforcing perceptions of human warmth on their websites thanks to more and more interactive technologies, the charitable sector cannot, for lack of human, technical and financial resources, make use of such technologies. This research paper demonstrates the potential of a simple tool: the socially rich photo. Although the literature has extensively documented how photos impact visitor behavior in online environments, research in the context of donations through charity websites is rare and has provided contradictory results. By focusing more closely on the role of the individual represented in such photos (the recipient of a donation versus the donor), our studies, conducted in France, offer additional insights on the subject as well as managerial advice for organizations.  相似文献

The research problem of this paper attempts to understand the effects of disorganized versus organized shelves on search information. Contemporary retail studies have tended to discover how the organization of displays can evoke increased consumer attention. Thus, the purpose is to examine how disorganization cues shelf displays foster surprise through information search and the implications of that process for visualizing low-price signals. In three experiments carried out using eye-tracking devices and face reader techniques (two in the laboratory and one in the field), empirical evidence is presented that disorganization cues can generate an increase in information search generated by cognitive processing, increased emotional surprise manifested levels via schema discrepancy, and perception of low-price provoked by the attempt to reduce the risk of choice.  相似文献

Rather than focusing on the spread of enterprises' bank loans, we focus on the impact of government spending expansion on the amount of bank loans obtained by enterprises. We first build a theoretical model to show that there are the demand effect and loan cost effect of government spending expansion on the bank loans and then use the fixed effects approach to analyze the bank loan distribution effect of government spending expansion by using the data of enterprises listed on the China Stock Exchange between 2003 and 2019. Empirical results show that the demand effect plays a leading role for the central government state-owned enterprises (SOEs), helping them obtain more bank loans from banks. In contrast, for private enterprises, the loan cost effect plays a leading role, hurting them in obtaining bank loans from banks. Further research shows that government spending expansion's crowding-in or crowding-out effect differs from Neoclassicism and (new) Keynesianism. This paper provides a new explanation for why the financing problem of private enterprises is getting worse in China. The policy implication is that when the government implements expansionary fiscal policies, it should also provide convenience for private enterprise financing through window guidance to prevent the expansionary fiscal policies from crowding out private enterprise bank loans.  相似文献

创新要素配置在投入产出两个环节中生成大量不完全技术信息,投入产出效率随机变动更加明显。从投入产出数据集合中提炼共同因子,与不可观测变量构成预测器,建立因子增广向量自回归模型(FAVAR),分析随机变动方差构成,测度投入产出效率随机变动程度。随机变动效应包括水平效应、稳定性效应和规模效应。投入产出效率自回归扰动项表示随机变动程度,将其细分为共同因子,计算预测器方差及其与投入产出效率的协方差。基于669家上市公司月度、季度、半年度和年度技术研发数据,比较分析投入产出效率随机变动程度及形成原因,引入脉冲响应法分析变量方差构成与变动特征,提出相关政策建议。  相似文献

We examine the impact of institutional investor networks on firm innovation in China. Employing the unexpected departure of mutual fund managers and the inclusion of the Shanghai-Shenzhen 300 index as identifications, we find that institutional investor networks have a positive impact on firm innovation. Specifically, firms that are hold by well-connected institutional investors are motivated to make R&D investments and receive greater patents than their counterparts. This positive influence is more pronounced for non-SOEs and for firms located in less-developed regions, indicating that institutional investor networks act as information flow facilitator and a value certifier to encourage innovation activities.  相似文献

森林公园旅游是森林旅游的重要组成部分,研究森林公园旅游区域协调发展对于推进森林旅游可持续发展和林业产业结构调整具有重要意义。以2010—2019年湖南省14个市州森林公园数量、面积、旅游接待人数和旅游收入数据为基础,运用位序—规模分布理论与首位分布理论,对湖南省森林公园旅游规模差异及其分布状况进行了分析。结果表明:(1)湖南各市州森林公园旅游发展的绝对差异在扩大,但相对差异变化不大。(2)湖南省森林公园旅游发展不均衡情况总体上表现为森林公园数量<森林公园面积<旅游接待人数<旅游收入的局面。(3)在排名上,大部分市州都出现了一定波动,但在旅游接待人数和旅游收入方面,张家界一直稳居首位,娄底的旅游收入排名有大幅度上升。文章最后简要探讨了这种差异形成的原因和应对措施。  相似文献

Developing and transitional countries often impose a wide variety of entry barriers on foreign direct investments (FDIs). One important reason behind these entry barriers is ideological taboos. However, do these taboos actually affect the inflow of FDIs? With the help of China’s “cultural system reform,” this study uses a panel data of 283 prefecture-level cities in China for 1994–2017 and the difference-in-differences method to evaluate the effect of the cultural system reform on regional FDI. We found that the cultural system reform remarkably promoted the inflow of FDIs by deregulating institutions and removing entry barriers, and the attraction of FDI has slowly increased along with the deepening of the reform. Our conclusions still hold after performing several robustness tests, thereby highlighting ideologies as important barriers to the inflow of FDIs into less developed countries.  相似文献

新冠肺炎疫情将对中国产业供应链的持续竞争力形成挑战,使企业面临人力短缺、成本增加、现金流紧张和供应链不确定性增高等问题,在企业供应链的原材料供应、采购管理、生产复工、物流以及市场等方面均会产生一定的负面影响,这对供应链弹性管理提出了新的要求。在政府层面,应建立综合、协同性的产业供应链风险管理和沟通机制,构建基于事件的产业供应链预警体系,保障企业供应链运营的资源体系,推动产业平台和产业集群带动供应链参与者建立供应链弹性体系。在企业层面,应建立基于企业事件的供应链预警体系,根据供应链预警信息和状况,合理规划供应链运营方式,运用数字化能力建设企业供应链弹性体系,稳定供应链运营,提升供应链效率。  相似文献
