Due to health concerns related to COVID-19, shoppers have learned to minimise social contact by adopting various contactless self-service technologies to fulfil their consumption needs. This study explores shoppers’ behavioural changes in relation to self-service, using the special research context of e-commerce self-collection services. By synthesising insights from the health psychology literature, this study proposes an affective-cognitive-social perspective to explain the pandemic-driven behavioural changes of self-collection users. The survey instrument is used for online data collection (n = 500), and a combined (descriptive and quantitative) method is adopted for data analysis. Our results suggest that, although with a relatively weak predictive power, the affective and cognitive appraisals of health risks lead to the reinforced usage of self-collection service. This also applies to the factors of action/coping planning and subjective norm. This study theoretically contributes to the self-service literature and creates managerial implications for retailers and logistics operators.

Panic buying has been observed across many regions during the COVID-19 pandemic which greatly disrupts supply chains and market economies. The determinants of panic buying, upon being identified, can be applied to control the escalation of panic buying behaviour that is highly detrimental to societies. This research aims to synthesise the dual-system theory and stimulus-organism-response framework to investigate into the causes of panic buying. Structural equation modelling is employed to analyse data collected from 508 residents in Singapore. The results reveal that panic buying can be explained as a response to both environmental stimuli and reflective thinking. Specifically, perceived susceptibility and perceived severity of a pandemic event as well as social influence and social norm can stimulate consumers' perceptions of scarcity and affective response, which in turn leads to the impulsive decision of panic buying; meanwhile, a rational reflection which is operationalised by perceived lack of control also influences panic buying. Furthermore, the perceived lack of control positively moderates the relationship of consumers' perceptions of scarcity and affective response on panic buying. Theoretically, this research provides a unique explanation of panic buying. The findings also provide managerial implications on dealing with panic buying in response to disasters such as a health crisis.

Arising from the global COVID-19 pandemic, social distancing has become the new norm that shapes consumers’ shopping and consumption activities. In response, the contactless channel (i.e., shopping online, self-collecting and returning parcels via delivery lockers) is ideally positioned to fulfil consumers’ shopping/logistics needs while avoiding all unnecessary social interactions. Thus, this study examines the factors that motivate consumers’ migration to the contactless channel by viewing consumers’ channel choice as both health-related and shopping behaviours. Anchored on the synthesised insights of protection motivation theory and automation acceptance theory, the conceptual framework and a series of hypotheses are proposed. A survey instrument is used for data collection, and the data are analysed using structural equation modelling. Our findings reveal that perceived channel characteristics such as compatibility and trust directly contribute to the relative value of the contactless channel; these characteristics are also correlated where trust perception reinforces compatibility perception. The channel characteristics are further influenced by consumers’ perceived susceptibility of COVID-19; that is, susceptibility perception enhances channel compatibility but decreases consumers’ trust in the contactless channel. However, the impacts of susceptibility become insignificant with a low level of severity perception, confirming the stage-based conceptualisation of severity. Furthermore, the severity perception of COVID-19 is found to amplify the positive impacts of susceptibility perception but attenuate its negative impact. Our study promotes a deeper integration between the health and service literature and encourages more interdisciplinary studies in this nexus. Considering the practical context of social distancing, our findings suggest a struggle between compatibility perception and trust concern that shapes consumers’ behaviours.

Due to the supply chain globalization, technology-oriented original equipment manufacturers are focusing on their core competencies by outsourcing the production to contract manufacturers. Many contract manufacturers also engage in remanufacturing and provide high quality remanufactured products in the market posing competition to the new products. This paper considers a supply chain with an original equipment manufacturer and a contract manufacturer. The contract manufacturer produces new products for the original equipment manufacturer and may compete with the original equipment manufacturer by producing and selling remanufactured products. The original equipment manufacturer can determine whether to authorize the contract manufacturer's remanufacturing. This paper investigates the wholesale price and retail price decisions for the new product and the conditions under which an authorization agreement can be reached between the two parties. In the analysis, two wholesale price settings are considered, the exogenous wholesale and endogenous wholesale price settings. In addition, three authorization decision bargaining scenarios are examined, including the original equipment manufacturer determining the authorization fee, the contract manufacturer determining the authorization fee, and two parties negotiating the authorization fee, to analyze the authorization cooperation outcomes via the generalized Nash bargaining framework. The results show that when the contract manufacturer determines the authorization fee, an authorization cooperation can never be reached whether in the exogenous or endogenous wholesale price setting. The original equipment manufacturer is more likely to set an authorization fee that leads to an authorization cooperation between the original equipment manufacturer and the contract manufacturer, especially when the contract manufacturer collects and remanufactures all the used products. Multiple factors influencing authorization cooperation decision are investigated, including the exogenous and endogenous wholesale price, production cost of new and remanufactured products, bargaining power of the two parties, and consumers' preference for remanufactured products.

The implementation of International Maritime Organization (IMO) 2020 sulfur cap requires ship operators to decrease fuels’ sulfur content and this may increase their demand for low-sulfur fuel (LSF). In anticipation, bunker companies can choose to upgrade their refining technology to produce better quality distillate and lighter oil. In this study, we consider a bunker supply chain consisting of bunker companies and a population of ship operators with two main marine fuel products, low-sulfur fuel (LSF) and high-sulfur fuel (HSF). We use Cournot game to model the competition between LSF and HSF under two different market channels (i.e., dual and single channels). The results show that bunker companies’ refining technology upgrading choice is affected by many operational parameters, such as the basic market demand, cost difference between LSF and HSF, market competition, variable and fixed cost for upgrading, the increase of market demand due to upgrading, and so on. Compared with a dual channel bunker company, a single channel bunker company is less likely to implement new refining technology. We further consider the scenario where bunker companies can make decisions after the realization of ship operators’ demand uncertainty. The findings are beneficial for both LSF and HSF bunker companies and may reach a win-win solution for bunker companies.

Due to the increasing focus on green consumerism, sustainability disclosure—company informing its stakeholders of its involvement in sustainability—is an integral part of stakeholder management. Nevertheless, the sustainability reports published by container shipping companies exhibit unique structures and content. Existing sustainability disclosure frameworks are generic and do not cater to B2B industries, such as container shipping. Moreover, limited studies have been conducted to explore the sustainability disclosure framework of the container shipping industry. With a hierarchical unsupervised text-mining method, the latent information of major listed container shipping companies' sustainability reports has been explored. A unified framework is produced comprising three primary dimensions: employee training and management, sustainable business management, and sustainable shipping operation. Each primary dimension has three secondary sub-dimensions. Theoretically, this research uncovers themes and patterns on how container shipping companies disclose sustainability. Managerially, this research guides container shipping companies on preparing and organizing sustainability disclosure. For regulators, policymakers, and global investors, this research also provides implications on evaluating container shipping companies’ sustainability performance and serves as a benchmark against broader sustainability goals such as sustainable development goals (SDGs).

The volatile characteristics of the tanker market pose challenges to forecasting. In addition, the volatile characteristics of newbuilding and secondhand ship prices, time charter rates, and scrap values make developing a unified framework of forecasting difficult. Most researchers have developed forecasting models and evaluated their performance based on a specific market. Such narrow development imposes difficulty for practitioners to choose a suitable model. Due to the boom of machine learning, many researchers are trying to boost the forecasting accuracy of shipping markets using machine learning. However, there are many hyper-parameters of the complex machine learning models and a slight variation of the model may cause significant performance degradation. This paper utilizes a forecast combination mechanism to forecast many time series collected from the shipping market, including newbuilding and secondhand ship prices, scrap values, and time charter rates. The models inside the combination pool are just linear functions. Finally, we compare their performance with conventional machine learning models and naïve forecasts using three error metrics and statistical tests. The statistical tests show that the combination of linear models is superior. The findings of this study also indicate that complex models do not boost forecasting accuracy necessarily.

Traditional behavior-based pricing (BBP) literature suggests that firms should offer lower prices to incentivize new customers to switch. However, at the time of switch, customers are often uncertain about their true needs or valuations of the product. Accordingly, they may experience repeat-purchase or switch-purchase regret, depending on whether they have bought a product from the same brand or switched to another brand. This paper investigates the impact of customers’ anticipated regret on firms’ BBP strategy and profits. Contrary to prior research which generally shows that firms performing BBP yield lower profits, we find that firms’ profits can increase or decrease in the presence of anticipated regret. When customers’ anticipated regret is sufficiently strong, firms can benefit from performing BBP. In addition, we find that firms have to change their traditional BBP strategy from rewarding new customers to rewarding repeat customers when repeat-purchase regret is sufficiently high.

Panic buying (PB), a typical consumer behaviour induced by crisis, was observed worldwide in the face of COVID-19 pandemic. Drawing on Survival Psychology and Maslow's motivation theories, this study introduced a theoretical model to establish the factors affecting consumers' PB and investigate their interrelationships. An online survey was designed and administered to 508 respondents in Singapore. Then, structural equation modelling was implemented to study the survey data. The results indicated that the effects of several constructs namely, normative social influence, observational learning, perceived severity, and perceived scarcity, with mediation by control, impose significant influence on consumers' PB. Analysis of total effects showed that normative social influence has the strongest effect on PB. This is followed by perceived scarcity, control, social trust, observational learning, and perceived severity. Two diverse research paradigms centring on Survival Psychology and Maslow's motivation theories were integrated to offer a logical explanation of the motivation driving PB. By utilising a theory-driven approach, the current study has offered a unique approach to interpreting consumers' PB. Overall, this study enhances current research on consumers' PB, offers new insights into understanding the motivating factors behind consumers' PB, and implicates policies on tackling hoarding situations in the event of crisis such as the COVID-19 pandemic.

As an important measure to combat COVID-19 pandemic, social distancing is observed worldwide and increasingly being regarded as a normative behaviour that guides consumers' daily activities. In response, consumers have embraced a variety of digital technologies that facilitate in-home or contactless shopping. This study examines the emerging presence of technologies in shopping activities under social distancing by: 1) conceptualising the structures of shopper-facing technologies, and 2) examining the interplay between task-technology fit and technology-trust that influences shoppers' adoption of the multi-dimensional technologies. Exploratory factor analysis and structural equation modelling are used for data analysis (n = 508). Our findings reveal three distinctive dimensions of shopper-facing technologies which are labelled as shopper-dominant (pre-)shopping technologies, shopper-dominant post-shopping technologies, and technology-dominant automations. Shoppers' adoption intention depends on their evaluations of the technology fit in performing shopping tasks characterised by contact avoidance/minimisation. The impacts of task-technology fit are further moderated by shoppers' trust in those technologies. More importantly, task-technology fit and technology trust are found to demonstrate differentiated explanatory powers towards shoppers’ adoption of the different categories of technologies.

Trade-in promotions allow consumers to turn in old products and receive a discount for purchasing a new item. Firms usually price discriminate consumers based on their purchase history (i.e. new or existing customers). However, behavioural research has shown that consumers exhibit loss aversion and brand loyalty after consuming a product that may influence economic outcomes. This paper examines the impact of consumers’ loss aversion and brand loyalty behaviour on firms’ trade-in promotion pricing strategy, profits, consumer surplus, and social welfare. Contrary to prior game theory research that generally shows that price discrimination based on purchase histories eventually results in lower profits for all firms, we find that firms’ profits from conducting price discrimination can increase with consumers’ loss aversion behaviour. We consider two scenarios where firms recognise and do not recognise consumers’ loss aversion and brand loyalty behaviour. We find that the profit with behaviour recognition is higher than that without behaviour recognition under the condition that consumers’ loss aversion concerns are sufficiently strong. However, both loss aversion and brand loyalty decrease consumer surplus. Besides, consumers’ loss aversion and brand loyalty behaviour can increase social welfare because they can reduce inefficient switching.

Except for the catastrophic accidents that have made headlines, public’s knowledge about the shipping industry remains limited. As a result, the public may form an unjust stereotype of the industry as ‘polluting’ and ‘unsustainable’, which reduces the industry’s attractiveness to its potential employees and indirect customers (i.e. end-consumers). It is high time for the industry to shape its public image by not only acting sustainably but also communicating the same to the public. Thus, this study examines the shipping industry’s sustainability communications in social media focusing on the Twitter interactions between the top container liners and the public. Adopting the 2030 Agenda and Sustainable Development Goals (SDGs) as a normative framework, this study analyses the strategic fit of the sustainability communications internally (i.e. congruence with core business) and externally (i.e. congruence with public expectation) by top shipping companies. A combined method of qualitative content analysis and quantitative statistic test is employed. Our findings suggest a trend of diversification in shipping companies’ sustainability communications which gradually extend from SDGs related to the industry’s core responsibilities to peripheral responsibilities. Contrarily, a trend of convergence in the public’s response is observed where the public’s attention is increasingly diverted from SDGs pertaining to the industry’s peripheral responsibilities to the core ones. Based on the opposite trends, theoretical and managerial implications for maritime scholars and industry players are discussed; moreover, sustainable communication strategies for the shipping industry are highlighted.

The cruise industry has suffered a huge loss due to the suspension of cruise operations during the COVID-19 pandemic. As the industry is preparing for recovery, there is an urgent need for research on cruise consumers’ psychology, in particular, the factors influencing their intention to use cruise services after the pandemic. This study employs theories, namely, the health belief model, trust theory and attitude theory, to investigate consumers’ use intention for cruise services after the pandemic. An online survey was administered to consumers in China’s tourism industry, where 376 responses were received. Subsequently, this study employs structural equation modelling to test its theoretical model consisting of hypotheses. The results show that consumers’ trust is directly influenced by health belief constructs including perceived safety threat, outcome expectation, self-efficacy and cues to action. Next, trust exerts a direct impact on consumers’ attitude and intention to use cruise services. Moreover, this study finds full and partial mediation effects. The findings provide a series of recommendations for cruise operators and policymakers in terms of marketing strategies, service design, public communication and health measures.

Purpose To gain competitive advantage, shipping companies need the abilities to manage environmental requirements, which this study refers to as sustainable shipping capabilities, including internal resources and external factors such as inter-firm collaboration. However, previous studies mainly focused on the effectiveness of internal resources, leading decision-makers in shipping companies to undervalue the significance of external relationships in managing sustainability issues and their impact on performance. Therefore, this paper aims to identify and examine the impacts of sustainable inter-firm collaboration on shipping companies' business performance (i.e. shippers' loyalty and financial performance). Design/methodology/approach A proposed model that explains the relationships between relation bonding strategies, sustainable inter-firm collaboration and business performance was developed. Accordingly, a survey questionnaire was constructed and sent to 294 shipping companies in Vietnam. Structural equation modeling was deployed to examine the validity of the measurement items and investigate relationships among the latent constructs. Findings The findings show that financial bonding strategies have the most significant impact on sustainable inter-firm collaboration, followed by social bonding strategies and structural bonding strategies. Furthermore, sustainable inter-firm collaboration has direct and indirect (via perceived shippers' loyalty) effects on business performance. Research limitations/implications Relational bonding strategies provide a unique perspective to sustainable inter-firm collaboration. This study also contributes to allocate external resources and capabilities to improve inter-firm collaboration, thereby maximizing financial performance. Originality/value This paper contributes to the literature by applying relational bonding strategies that determine the key factors enabling sustainable inter-firm collaboration.

The challenge of accurately forecasting a time series covers numerous disciplines, from economics to engineering. Among the thousands of machine learning models, random vector functional link (RVFL) is a robust and efficient model which has demonstrated its success in various challenging forecasting problems. RVFL is an efficient universal function appropriator that randomly generates the weights between the input and hidden layers. However, RVFL still lacks the strong ability to extract meaningful multi-scale features from input data because of the single-layer random mapping of enhancement nodes. Therefore, we propose to combine the empirical wavelet transformation (EWT) with RVFL to strengthen the multi-scale feature extraction ability. The EWT can decompose the original time series into several sub-series which carry the information of different frequencies. Besides, we propose a walk-forward decomposition mechanism to implement the EWT. By introducing such a walk-forward mechanism and the combination of EWT and RVFL, the hybrid model achieves high accuracy and averts the data leakage problem during forecasting. A detailed and comprehensive empirical study on twenty-six public time series validates the proposed model’s superiority compared with ten popular baseline models from the literature.

Port State Control (PSC) guarantees that foreign ships do not jeopardize marine safety, security, and the environment when entering foreign ports. To share inspection information and improve the efficiency of PSC, countries in the same regions cooperate and follow memoranda of understanding (MoUs). Globally, a total of ten MoUs govern three different inspection regimes designed to select and inspect substandard ships. In this study, we use a super-slacks-based measure (super-SBM) to evaluate and compare the inspection efficiency of the three inspection regimes implemented by these ten MoUs and relies on the Malmquist production index (MPI) to identify the most applicable regimes. Our analyses produce three main conclusions. First, we use the average scores of the super-SBM in the past 11 years to confirm the efficiency rankings of the ten MoUs. Second, we combine the average efficiency scores of the three inspection regimes to show that the New Inspection Regime (NIR) is more economically efficient than other inspection regimes. Third, we use MPI scores to obtain a better understanding of the efficiency changes in MoUs' productivity over time and confirm that the NIR is more stable than other inspection regimes.

E-commerce logistics services are increasingly offering innovative solutions that invite consumers’ co-creation. Although value co-creation empowers consumers, it also connotes a sense of exploitation. This study explores the fairness perspective of co-creating satisfactory logistics services, using self-collection service as an example. A theoretical model based on synthesized insights of Fairness Heuristics and Selective Information Processing was conceptualized and validated. Survey data were collected from 680 actual self-collection users. The findings show a three-pronged service evaluation process with consumers’ fairness perception as a central anchorage. Furthermore, the satisfaction formation process is moderated by consumers’ pre-formed beliefs leading to biased evaluations of co-creation experiences. This study contributes to literature with a contingent framework of consumers’ participation in logistics services, suggesting a heuristic-based process of value co-creation among the consumers. We also create practical insights on consumers’ preformed beliefs toward the logistics services and service providers that lead to a biased satisfaction formation process.

Purpose E-commerce last-mile logistics is undergoing dramatic changes. By inviting consumers to participate in self-collection, they collectively form a mass crowd of resources that can be integrated into last-mile logistics. However, consumers' participation may lead to a spectrum of value outcomes from value co-creation to co-destruction. Therefore, the purpose of this paper is to critically examine the value formation process focussing on micro-level practices and resource outcomes. Design/methodology/approach Anchored on practice theory and resource conservation theory, content analysis is adopted to analyse 546 practice-based experiences extracted from a leading social media platform. Findings The analysis reveals five sequential practices of self-collection: purchasing, delivering, notifying, receiving and confirming. Furthermore, the co-created practices are characterised by gains in material, esteem, social and energy resources of the interacting actors. Meanwhile, the co-destructed practices cause a chain of resource losses, where the interacting actors suffer primary losses which subsequently triggers consumers' coping behaviours and further destroys resources for all. Research limitations/implications Focussing on constituent service practices, this study zooms into the value formation process. The authors contribute to logistics literature with a service-dominant logic by stressing end-consumers' involvement in the creation and consumption of last-mile logistics. Originality/value This study conceptualises the sources and consequences of the nuanced service practices (value formation or destruction) of self-collection. A unified framework is thus proposed, which guides logistics service providers to channel consumers towards more constructive participation in last-mile logistics.

The COVID-19 pandemic has seen an unmatched level of panic buying globally, a type of herd behavior whereby consumers buy an uncommonly huge amount of products because of a perception of scarcity. Drawing on the health belief model, perceived scarcity, and anticipated regret theories, this paper formulated a theoretical model that linked the determinants of panic buying and analyzed their interrelationships. Subsequently, data were collated from 508 consumers through an online survey questionnaire in Singapore that was conducted during the early stage of the pandemic, before the onset of the circuit breaker in April 2020. Next, an analysis of the results was done through structural equation modeling. It showed that the effect of the health belief model dimensions (i.e., perceived susceptibility, perceived severity, outcome expectation, cues to action, and self-efficacy) on panic buying is partially mediated by the consumers’ perceived scarcity of products. Furthermore, the effect of perceived scarcity on panic buying is partially mediated by consumers’ anticipation of regret. This paper expands on the current theoretical understanding of panic buying behavior, giving insights into the possible measures and solutions that policymakers and relevant stakeholders can uptake to manage panic buying in future a pandemic or health crisis.

This article determines the quality factors which improve the satisfaction of logistics services, and the specific evaluation items that customers value. Moreover, this study verifies the moderating effect of consumers on the perceived importance of last-mile logistics services, and its impact on logistics service satisfaction. Through a literature review, the conceptual model is determined, and measurement scales are developed. Furthermore, we collect data through online surveys and employ structural equation modeling, hierarchical regression analysis, and importance–performance analysis methods in order to analyze the collected data, and to test the research hypotheses. The findings of this study are as follows. First, the qualities of personal contact, timeliness, and empathy in the fresh food e-commerce logistics service quality evaluation system have a significant positive impact on the fresh food e-commerce logistics service consumer satisfaction, but the delivery quality and information quality are not significant. Second, consumers’ perceived importance of last-mile logistics services has a positive and significant impact on the consumer satisfaction of fresh food e-commerce logistics services. Moreover, as a moderating variable, its moderating effect has limitations: it only affects the relationship between information quality, timeliness quality, empathy quality, and consumer satisfaction. Finally, in the three evaluation dimensions of information quality, timeliness quality, and empathy quality, specific items that need to be further improved are identified. This study enriches and supplements the empirical research in the field of fresh food e-commerce logistics, and provides academic literature with a reference value for fresh food e-commerce logistics enterprises.
