Abstract
Purpose
The purpose of this paper is to investigate the influence of food retailer's Approaching the Expiration Date (AED) labelling on consumers' retailer-related response. Specifically, the main effect of food retailer's AED labelling on consumers' patronage intention, the mediation effect of food retailer's concern for consumers and the boundary condition of this effect are explored. The selected context of research is that food retailers are reluctant to stick an AED label on nearly expired food due to negative effect on selling them.
Design/methodology/approach
Two separate pretests and two separate experiments have been conducted to investigate the influence of food retailer's AED labelling on patronage intention. Pretest 1 develops the stimulus material of food retailer's AED labelling. Study 1 investigates the influence of AED labelling on patronage intention and mediation effect of consumers' perception of retailer's concern for consumers. Pretest 2 develops the stimulus material of government regulation on food retailer's AED labelling. Study 2 explores the boundary condition of the positive effect, namely the moderation effect of whether retailer's AED labelling is voluntary or mandatory.
Findings
The main findings of this research highlight the positive influence of food retailer's AED labelling on consumers' patronage intention. In addition, the current research reveals the underlying mechanism food retailer's concern for consumers and the boundary condition whether the AED labelling is voluntary or mandatory.
Originality/value
Although previous researches has explored the effect of food retailer's AED labelling on consumers' response, most of them focus on consumer purchase intention of the nearly expired food and neglect its effect on consumers' food retailer-related response. It is a need for food retailer to explore the potential positive influence of food retailer's AED labelling on consumers' patronage intention.

Abstract
Purpose
This study aims to present a type of metamorphic mechanism-based quadruped crawling robot. The trunk design of the robot has a metamorphic mechanism, which endows it with excellent crawling capability and adaptability in challenging environments.
Design/methodology/approach
The robot consists of a metamorphic trunk and four series-connected three-joint legs. First, the walking and steering strategy is planned through the stability and mechanics analysis. Then, the walking and steering performance is examined using virtual prototype technology, as well as the efficacy of the walking and turning strategy.
Findings
The metamorphic quadruped crawling robot has wider application due to its variable trunk configuration and excellent leg motion space. The robot can move in two modes (constant trunk and trunk configuration transformation, respectively, while walking and rotating), which exhibits outstanding stability and adaptability in the examination and verification of prototypes.
Originality/value
The design can enhance the capacity of the quadruped crawling robot to move across a complex environment. The virtual prototype technology verifies that the proposed walking and steering strategy has good maneuverability and stability, which considerably expands the application opportunity in the fields of complicated scene identification and investigation.

Abstract
Purpose
Extant research has paid considerable attention to the effects of enterprise social media (ESM) on employees' work attitudes and outcomes, yet the authors know little about the influence of job demands arising from the implementation of ESM. Drawing on resource allocation theory, the purpose of this study is to unravel how ESM-related job demands influence employee outcomes.
Design/methodology/approach
This study conducts a two-wave time-lagged survey of 223 employees from 53 teams in 14 financial service firms in China to test the conceptual model.
Findings
The findings of this paper indicate that ESM-related job demands have indirect effects on employee outcomes (i.e. job satisfaction and work–family conflict), and emotional exhaustion plays an intermediary role in these relationships. Specifically, ESM-related job demands have a U-shaped effect on emotional exhaustion.
Originality/value
This study combines job demands with ESM research and clarifies the mechanism behind how ESM-related job demands at different intensity affect employee outcomes from a new perspective. Moreover, this study’s findings suggest several beneficial courses of action for managers to take advantage of ESM.

The purpose of this paper is to introduce an augmented high-order capital asset pricing model (AH-CAPM) as a new risk-based model to price stocks.
Abstract
Purpose
The purpose of this paper is to introduce an augmented high-order capital asset pricing model (AH-CAPM) as a new risk-based model to price stocks.
Design/methodology/approach
The AH-CAPM is defined as a linear model with high-order marginal moments and co-moments from the joint distributions of the sorted stock portfolio returns and the market return.
Findings
The performance of the AH-CAPM is tested in the Chinese and US stock markets. Empirical results show that the high-order marginal moments and co-moments from the joint distributions in AH-CAPM contain the risk and return information implied by the Fama–French factors, indicating it as a better risk measurement. Moreover, the AH-CAPM performs better than the Fama–French three-factor model and the Carhart four-factor model in both the Chinese and US stock markets.
Originality/value
Overall, this study introduces a new asset pricing model with better measurements to incorporate risk information in the stock market.

This study aims to provide empirical evidence on the relationship between formal institutions and stock price crash risk from a global perspective.
Abstract
Purpose
This study aims to provide empirical evidence on the relationship between formal institutions and stock price crash risk from a global perspective.
Design/methodology/approach
This paper uses data of 35,468 firms globally over the years 1987–2019 and address the endogeneity issue by employing the Mundlak random effects estimator.
Findings
The authors find a significant negative impact of institution quality on stock price crash risk (i.e. better institutions reduce crash risk), after controlling for common determinants of crash risk such as leverage, return on asset, firm size, investment, etc. as well as macro factors such as GDP growth. This effect is robust to different measures of crash risk and sub-indicators of institutions quality. In addition, the authors also find this effect to be universally present in economies characterized by different levels of income.
Originality/value
To the best of the authors' knowledge, there's no known study that explores the potential causal relationship between institution quality and stock price crash risk. Therefore, the research topic in this study is original and can contribute significantly to the existing literature.

Abstract
Purpose
This study aims to build on equity theory to assess the effect of chief executive officer (CEO) underpayment on the accumulation of firm-specific knowledge, accounting for the moderating effects of the CEO compensation gap and the clarity of the board’s informal hierarchy.
Design/methodology/approach
This study starts with all firms listed in the Execucomp database for the period 1992 to 2006. Then, all data sources are merged and entries with missing information are excluded. The final data set used for model estimations includes 1,152 firm-year observations. The command xtreg in Stata 12 with the fixed-effect option (fe) is used to estimate the relationship between CEO underpayment and firm-specific knowledge.
Findings
This study proposed and examined the role of CEO underpayment in discouraging CEO willingness to invest firm-specific human capital and, accordingly, to adopt a strategy of accumulating lower levels of firm-specific knowledge assets. The empirical analyses strongly support this argument. Moreover, CEO compensation gaps and the informal hierarchy of boards negatively moderated this relationship. That is, CEO underpayment had a weaker negative effect on firm-specific knowledge when the CEO compensation gap and the clarity of the board’s informal hierarchy were high.
Originality/value
Prior studies from the knowledge-based perspective have focused on the importance of firm-specific knowledge in enabling a firm to achieve superior financial performance. However, relatively little attention has been paid to CEOs’ willingness to accumulate firm-specific knowledge. The present study contributes to the knowledge-based view of the firm. This study integrates equity theory with the knowledge-based view of the firm by highlighting how unfair compensation of CEOs may discourage them to fully realize a firm’s potential to generate specific knowledge. By incorporating the fairness issue of CEO compensation into the knowledge-based view, this study contributes to a deeper understanding of the origins of firm-specific knowledge.

Abstract
Purpose
This study examines whether common directors are guilty of contagion of corporate frauds from the customer side and, if so, how contagion occurs. Moreover, it explores a way to mitigate it, which is the increased digital orientation of firms.
Design/methodology/approach
Secondary data analysis is applied in this paper. We extract supply chain relations from the China Stock Market and Account Research (CSMAR) database as well as corporate fraud data from the same database and the official website of the China Securities Regulatory Commission (CSRC). Digital orientations are estimated through text analysis. Poisson regression is conducted to examine the moderating effect of common directors and the moderated moderating effect of the firms’ digital orientations.
Findings
By analysing the 2,096 downstream relations from 2000 to 2021 in China, the study reveals that corporate frauds are contagious through supply chains, while only customers’ misconduct can contagion to upstream firms. The presence of common directors strengthens such supply chain contagion. Additionally, the digital orientation can mitigate the positive moderating effect of common directors on supply chain contagion.
Originality/value
This study highlights the importance of understanding supply chain contagion through corporate fraud by (1) emphasising the existence of the contagion effects of corporate frauds; (2) understanding the potential channel in the process of contagion; (3) considering how digital orientation can mitigate this contagion and (4) recognising that the effect of contagion comes only from the downstream, not from the upstream.

Abstract
Purpose
Online trust is a key factor for successful online transactions. To some extent, online health consultation can be considered an online transaction. Owing to the unique physician–patient relationship, patients' choice of physicians within an online health consultation setting may not only be based on rational judgments but also considerably affected by their feelings. Hence, the purpose of this study was to explore which physicians' attributes affect patients' cognitive and affective trust in physicians, as well as how these two variables and their association affect patients' willingness to choose.
Design/methodology/approach
Based on the broad conceptual framework of online trust, this paper proposed a set of hypotheses that were tested through analyzing survey data using structural equation modeling techniques.
Findings
Results showed that physicians' ability had a significant positive influence on patients' cognitive trust in the physician; physicians' integrity and benevolence had a significant positive influence on patients' affective trust in the physician; cognitive and affective trust had a significant positive impact on patients' willingness to choose and there were significant positive interactions between affective and cognitive trust.
Originality/value
This study theoretically enriches the generic model of online trust. From the practical perspective, it will provide physicians working in online health consultation platforms and relevant practitioners with baseline information on the topic and advice for decision-making toward service enhancement and clientele improvements.
