资产价格泡沫的宏观调控:识别、传导和应对

以稳物价、促增长为传统目标的宏观政策要不要以及如何对资产价格泡沫进行调控,在理论上和实践上一直存在争议:第一,资本市场的高频联动、金融摩擦、投资者的认知偏差共同造成资产泡沫的根源、泡沫规模和发展规律在识别上都极端困难.第二,利率渠道、信贷渠道、风险承担渠道等传导机制对资产泡沫产生的影响错综复杂.本文从资产泡沫的识别和泡...     

Social media celebrities and new world order. What drives purchasing behavior among social media followers?

Social media celebrities (SMCs) and social media platforms (SMPs) have become indispensable in today's business and marketing settings. Drawing on the celebrity influence model (CIM), this study examines the impact of SMCs on their followers' purchase intention and the moderating influence of SMP usage on the relationships between (a) SMCs and their followers' purchase intention, (b) para-social relationships (PSR) and purchase intention, and (c) identification and purchase intention. We collected 665 valid responses via an online questionnaire in China and then employed partial least squares structural equation modelling (PLS-SEM) to examine the proposed relationships between the variables. The findings revealed that SMCs do not significantly influence their followers' purchase intention directly; however, they do exert such influence through PSR and identification. The results further indicated that SMP usage moderates the effect of PSR and identification on purchase intention. Our study offers both theoretical and managerial contributions. Theoretically, the incorporation of CIM into this study's model augments the PSR and identification literature in the context of SMCs. Again, the moderating effect of SMP usage that we reveal is novel in the social media literature. In practice, marketers in China should consider the credibility and rapport a particular social media celebrity has with his or her followers before contracting that particular celebrity to endorse their products.     

Investment in identity in the field-Nudging refugees’ integration effort

Social identity greatly affects behavior. However, less is known about an individual’s investment in identification, i.e., in belonging to a social group. Using a language-learning platform utilized by refugees to learn the host country’s language, we design a field experiment that allows us to make effort as an investment in a new group identity salient. The social identity in our treatment is a refugee’s identification with the host society. We modified a mailing to 5600 refugees who use an online language-learning platform to learn the host country’s language. These treatment emails make salient that improving the host country’s language ability increases the belonging to the host society. Our analysis reveals that the treatment has a significant positive effect on the effort exerted on the language-learning platform, leading to more completed exercises and more time spent learning the host country’s language. This suggests that refugees invest in becoming part of the host country’s society for its social identity component. Our findings can inform policy considerations on the use of nudges for other integration measures intended for refugees and immigrants in general.     

A data-driven decision support system with smart packaging in grocery store supply chains during outbreaks

The unexpected emergence of the COVID-19 pandemic has changed how grocery shopping is done. The grocery retail stores need to ensure hygiene, quality, and safety concerns in-store shopping by providing “no-touch” smart packaging solutions for agri-food products. The benefit of smart packaging is to inform consumers about the freshness level of a packaged product without having direct contact. This paper proposes a data-driven decision support system that uses smart packaging as a smart product-service system to manage the sustainable grocery store supply chain during outbreaks to prevent food waste. The proposed model dynamically updates the price of a packaged perishable product depending on freshness level while reducing food waste and the number of rejected customers and maximising profit by increasing the inventory turnover rate of grocery stores. The model was tested on a hypothetical but realistic case study of a single product. The results of this study showed that stock capacities, freshness discount rate, freshness period, and quantity discounts significantly affect the performance of a grocery store supply chain during outbreaks.

What if the supervisor has a different gender? The roles of value fit,identification, and beliefs in gender equality

In the past decades, the number of female employees and managers has strongly increased in most developed countries. This demographic development emphasizes the importance to investigate gender dissimilarity between employees and their supervisor and how it can be managed to elicit beneficial gender dissimilarity effects on employees’ attitudes and interpersonal interactions. Past gender dissimilarity research often assumes women and men to have different values. Due to these value differences, women and men should be less satisfied with a supervisor who has a different gender. However, past research reported inconsistent gender dissimilarity effects on employees’ satisfaction and other work-related satisfaction variables. To clarify gender dissimilarity effects on employees’ satisfaction with their supervisor, we analyze the moderating role of an employee’s beliefs in gender equality. We further draw on social identity theory and investigate value fit with the supervisor and identification with the supervisor as underlying mechanisms of gender dissimilarity effects. To test our research model, we conducted a three-wave survey study with 463 employees. Value fit and identification with the supervisor mediated the relationship between gender dissimilarity and employees’ satisfaction with supervisor. This indirect relationship was only significant for employees with low beliefs in gender equality. This means high beliefs in gender equality can offset dysfunctional gender dissimilarity effects.     

创业者调节焦点、组织间信任与新企业资源识取——有调节的中介效应

对面临着资源约束的新企业而言，如何从供应链上下游识别并获取所需资源在一定程度上决定了新企业的生存与发展。大多数研究强调了创业者调节焦点在影响新企业战略决策与行为的重要作用，然而现有文献在深入揭示创业者调节焦点对新企业资源识取的作用机理方面仍较为薄弱。针对这一问题，该研究以213家一汽—大众供应链上的新企业为研究对象，整合注意力基础观、调节焦点理论，考察了创业者调节焦点与新企业资源识取之间的逻辑关系，并探讨了善意信任和能力信任的中介作用以及权力不对称的调节作用。结果表明：（1）创业者促进焦点与预防焦点均会对能力信任产生正向影响，两者之间的差异并不显著；与能力信任相比，促进焦点对善意信任正向作用更强；预防焦点不对善意信任有显著的影响。（2）善意信任、能力信任对促进焦点与新企业资源识取的关系起到中介作用，能力信任对创业者预防焦点与新企业资源识取的关系起到中介作用。（3）权力不对称负向调节了创业者预防焦点与资源识取之间的间接关系。
