世博日志（三）

世博会首日试运行，轨道地铁几近瘫痪。2010年4月20日，是上海世博会第一个试运行日。什么叫试运行？就是拉一批人做试验，来冲击一下世博园区，看各项准备工作是否已经到位。对整个上海而言，这是一个特殊的日子。我也有幸成为试验品之一。早上出门，天空阴沉，坐上2号线地铁，到人民广场转8号线前往世博园区耀华路站。

浅析我国乡村医生队伍短缺的原因及对策建议

中国是一个农业大国,拥有着8亿多的农民。而作为这8亿多农民健康的"守门人",中国的乡村医生却少的可怜,村医空白村的数量越来越多。而到目前为止,我国的乡村医生的平均年龄已经在60岁以上。这说明乡村医生即将面临着"后继乏人"的局面。本文从分析目前我国乡村医生短缺的主要原因入手,并就这些原因提出了一些建议。

Herding in the bad times: The 2008 and COVID-19 crises

The objective of this paper is to analyze the imitation behavior of investors in especially convulsed periods, such as the 2008 financial crisis and the recent global pandemic, both of which could affect investors' emotions and behavior, although both have different characteristics and might have different implications. The cross-sectional dispersion of returns is used to measure the level of herding in the markets of Spain and Portugal, using a survivorship-bias-free dataset of daily stock returns during the period January 2000–May 2021, in turn divided into several sub-periods classified as pre-2008 crisis, 2008 crisis, post-2008 crisis, Covid-19 and post Covid-19. Additionally, the existence is studied of differences between days of positive and negative returns, or between days of high volatility compared to the rest, and whether the cross-sectional dispersion of returns in one market is affected by the cross-sectional dispersion of returns in the other market. The results indicate that herding appears with greater intensity in periods prior to the crisis, disappearing during the financial crisis and reappearing, although with less intensity, after it, while it is not generally detected in Covid-19 times. However, herding behavior can be observed in the market during the pandemic on high volatility days.     

Agility,adaptability, and alignment: new capabilities for PSM in a post-pandemic world

Purchasing and Supply Management (PSM) was overwhelmed by a perfect storm during the Covid-19 emergency, in both the public and private sectors. Many organizations were caught unprepared, and it became evident that they did not have the capabilities needed to quickly react and respond to changes caused by the pandemic. This poses the questions of where and how PSM systems should evolve to better contribute to organizational responsiveness to crisis events in the future. In this Editorial, which introduces the “PSM learning from the pandemic: transforming for better crisis management” Notes and Debates special issue, the six contributions included in this issue are discussed. We relate the evidence included in the contribution to three critical capabilities of supply chains in the post-Covid-19 business environment – agility, adaptability, and alignment – and, in this editorial, we discuss how they can be conceptualized from a PSM perspective. From a theoretical perspective, we provide a starting point for future studies that want to focus on how these capabilities can be deployed in PSM, and how they impact the supply network design. From a managerial perspective, these definitions provide preliminary points of discussion on what organizations can do to enhance these capabilities in the future.

Entrepreneurship and the systemic consequences of epidemics: A literature review and emerging model

The Covid-19 epidemic is a global challenge requiring adequate public and private responses to overcome the emergency, shape new development trajectories, and prepare for future outbreaks. As socioeconomic turning points, epidemics imply an entrepreneurial response in which not only managers and entrepreneurs, but also policymakers, health professionals, and civil society as a whole are active participants. Using the PRISMA methodology, we provide a comprehensive review of the complex interactions between entrepreneurship and epidemics over time. Applying a combined Kirznerian-Schumpeterian theoretical framework, we find that, in the short term, epidemics trigger a wave of Kirznerian entrepreneurship aimed at reducing the uncertainty generated directly and indirectly by the medical emergency. In the long term, as medical uncertainty abates, Schumpeterian entrepreneurship can contribute to transforming the post-crisis environment, either supporting or undermining the public reaction to the crisis and determining the path of institutionalization, in the process of defining a new normal. Thus, epidemics could lead to unpredictable socioeconomic and technological improvements, but also to highly undesirable outcomes. The construction of a satisfactory new normal requires the integration of entrepreneurial capabilities within the public sector and an explicit policy of cooperation with the private sector. Therefore, as the short-term phase of the Covid-19 pandemic draws to a close, policymakers must shift their focus away from restrictions and obligations towards a collaborative framework supportive of private entrepreneurial efforts.

     

疫情防控常态化下的世界经济战略走向

新冠疫情的出现冲击了世界经济,从经济全球化和全球经济治理体系两个维度分析疫情对世界经济的影响以及世界经济未来走向,研究发现:(1)新冠疫情通过影响全球价值链、贸易投资和就业环境阻碍经济全球化进程,中美矛盾升级、原有治理体系规则未与时俱进和激进政策的不确定性对全球经济治理体系提出新的挑战;(2)新冠疫情强化了世界各国对人类命运共同体的认识,将人类命运共同体融入全球治理体系将是未来治理的重要趋势;(3)新冠疫情可能会使世界经济格局出现新的变化,而中国在此次疫情中高效率的抗疫举措将进一步提升自身在世界经济格局中的地位和参与度。

Multilevel IRT models for the analysis of satisfaction for distance learning during the Covid-19 pandemic

The Covid-19 pandemic played a relevant role in the diffusion of distance learning alternatives to “traditional” learning based on classroom activities, to allow university students to continue attending lessons during the most severe phases of the pandemic. In such a context, investigating the students' perspective on distance learning provides useful information to stakeholders to improve effective educational strategies, which could be useful also after the end of the emergency to favor the digital transformation in the higher educational setting.Here we focus on the satisfaction in distance learning for Italian university students. We rely on data comprising students enrolled in various Italian universities, which were inquired about several aspects related to learning distance.We explicitly take into account the hierarchical nature of data (i.e., students nested in universities) and the latent nature of the variable of interest (i.e., students' learning satisfaction) through a multilevel Item Response Theory model with students' and universities' covariates.As the main results of our study, we find out that distance learning satisfaction of students: (i) depends on the University where they study; (ii) is affected by some students' socio-demographic characteristics, among which psychological factors related to Covid-19; (iii) is affected by some observable university characteristics.

Deriving equity risk premium using dividend futures

In this paper I present a simple stock price decomposition model using the dividend discount model and dividend futures. The main contribution of this paper is the use of dividend futures which represent the risk-adjusted expectations of future dividends. This allows for the calculation of the implied equity risk premium and the decomposition of stock price movements into individual components. Due to the use of daily market data, this method can take into account the structural changes associated with falling interest rates and the Covid-19 pandemic. I empirically show the risk premium development of the S&P 500 Index and Euro Stoxx 50 Index in the last decade.
