A new multiscale decomposition ensemble approach for forecasting exchange rates

Due to the high complexity and strong nonlinearity nature of foreign exchange rates, how to forecast foreign exchange rate accurately is regarded as a challenging research topic. Therefore, developing highly accurate forecasting method is of great significance to investors and policy makers. A new multiscale decomposition ensemble approach to forecast foreign exchange rates is proposed in this paper. In the approach, the variational mode decomposition (VMD) method is utilized to divide foreign exchange rates into a finite number of subcomponents; the support vector neural network (SVNN) technique is used to model and forecast each subcomponent respectively; another SVNN technique is utilized to integrate the forecasting results of each subcomponent to generate the final forecast results. To verify the superiority of the proposed approach, four major exchange rates were chosen for model comparison and evaluation. The experimental results indicate that our proposed VMD-SVNN-SVNN multiscale decomposition ensemble approach outperforms some other benchmarks in terms of forecasting accuracy and statistical tests. This demonstrates that our proposed VMD-SVNN-SVNN multiscale decomposition ensemble approach is promising for forecasting foreign exchange rates.     

How uncivil customers corrode the relationship between frontline employees and retailers

This study investigates the effects of customers’ uncivil treatments on frontline retail employees’ emotions, deviant behaviors and relationship with the retail organization. Our theoretical model is based on both marketing and personnel management literatures. 415 frontline retailing American employees answered our questionnaire. Employees treated uncivilly by customers feel angry but have to hide their negative emotions, which leads them to emotional exhaustion and deviant behaviors. Paradoxically, employees’ strong commitment to their retailing organization brings about more deviant behaviors. We propose some managerial strategies to cope with uncivil customers, as well as future research on this important and under-researched topic.     

Effects of perceived constraints and negotiation on learned helplessness: A study of Chinese senior outbound tourists

Learned helplessness is an important psychological construct that may influence senior tourists' subjective wellbeing while travelling. Employing a mixed-method approach and a multi-sample design, this study examines how Chinese senior outbound tourists’ perceived travel constraints and negotiation efforts affect learned helplessness in outbound travel. We identified four perceived constraints (perceived incapability, lack of suitable travel agencies and services, lack of information and personal support, and complex travel decision-making) and three negotiation strategies (seeking family support, physical/health preparation, and learning). Multiple regression analyses showed that among the four perceived constraints, only perceived incapability increased learned helplessness significantly; conversely, negotiation in general reduced learned helplessness. However, not as expected, negotiation was not founded to be a moderator between perceived constraints and learned helplessness. Theoretical and practical implications are also discussed.     

The role of loyalty programs in boosting hotel guest loyalty: Impact of switching barriers

This study examines the relationships among the perceived value of a loyalty program, customer satisfaction with a loyalty program, affective commitment, switching barriers, and customer brand loyalty in the hotel context. An online survey method with a quantitative approach was used. Our results from a structural equation model revealed that the perceived value of a loyalty program is essential in the formation of customer brand loyalty. Lastly, findings from an indirect analysis showed that affective commitment and switching barriers mediated the relationship between the perceived value of a loyalty program and customer brand loyalty. Overall, our research will help researchers and practitioners demonstrate to the industry that the loyalty program is a crucial strategy for customer loyalty and helps develop competitive loyalty programs for success.

The effect of specific discount pattern in terms of price promotions on perceived price attractiveness and purchase intention: An experimental research

This study aims to investigate consumer perceptions and reactions in terms of specific discount patterns (fixed price, 40% discount, discount from 500 TL to 300 TL and 20% + 25% discount) in price promotion. According to the results, specific discount patterns in price promotion have a significant effect on perceived price attractiveness and purchase intention. When the specific discount patterns in price promotion and gender interaction were analyzed in terms of perceived price attractiveness, the scenario of the “discount from TL 500 to TL 300” significantly differentiated from both the control scenario (fixed price) and experimental scenarios for female. For males, no significant difference was found between the control and experimental scenarios. In terms of purchase intention, a significant difference was found between the fixed price scenario and the discount scenario from 500 TL to 300 TL and between the fixed price and 20% + 25% discount scenario. The theoretical managerial implications of the study were discussed, and future research suggestions were presented.     

Shopping intention at AI-powered automated retail stores (AIPARS)

Artificial Intelligence (AI) is transforming the way retail stores operate. AI-Powered Automated Retail Stores are the next revolution in physical retail. Consumers are facing fully automated technology in these retail stores. Therefore, it is necessary to scrutinize the antecedents of consumers' intention to shop at AI-Powered Automated Retail Stores. This study delves into this area to find the predictors of consumers’ intention to shop at AI-Powered Automated Retail Stores. It extends the technology readiness and acceptance model by the addition of AI context-specific constructs such as Perceived Enjoyment, Customization and Interactivity from the present literature. The proposed model is tested by surveying 1250 consumers & the data is analyzed using the PLS-SEM technique and empirically validated. The outcome of the study reveals that Innovativeness and Optimism of consumers affect the perceived ease and perceived usefulness. Insecurity negatively affects the perceived usefulness of AI-powered automated retail stores. Perceived ease of use, perceived usefulness, perceived enjoyment, customization and interactivity are significant predictors of shopping intention of consumers in AI-powered automated stores. This research presents insightful academic and managerial implications in the domain of retailing and technology in retail.     

Is there life after degeneration? The organizational life cycle of cooperatives under a ‘grow‐or‐die’ dichotomy

This article provides an in‐depth, longitudinal analysis combining real‐time and retrospective data on a set of Mondragon's industrial cooperatives that are organized as international groups. We examine the life cycle of these international cooperative groups, which is expected to evolve differently to that of small‐ and medium‐sized cooperatives that operate exclusively on a local scale. The article is theoretically informed by the cooperative life cycle theory, as well as by recent insights from the degeneration and regeneration theses. Our analysis yields an intricate picture of the evolution of cooperatives faced with a ‘grow‐or‐die’ dichotomy. On the one hand, our findings reject the highly simplistic and deterministic view of the degeneration thesis by demonstrating that these cooperatives can mobilize resources to revitalize cooperative values and practices. On the other, we find that regeneration may not occur in a consistent, sequential fashion as the previous literature suggests, but rather degenerative and regenerative tendencies can occur simultaneously, even leading to long‐lasting, unresolvable situations. In light of this, the article asks future research to draw on power‐aware and politically informed approaches for further understanding of how cooperatives manage the tensions at each organizational stage of their life cycle, and of which organizational actors benefit, and how, from reversing some degenerative tendencies while maintaining others intact.     

Effects of CSR on affective organizational commitment via organizational justice and organization-based self-esteem

This study examined how employee perceptions of corporate social responsibility (CSR) influenced their affective organizational commitment (AOC) via procedural justice and organization-based self-esteem (OBSE). Using survey data collected from 203 employees working for a hospitality company, hypotheses were tested using structural equation modeling. The results showed that economic and philanthropic CSR did not have significant effects on procedural justice, but had significant direct effects on AOC. The findings also showed that procedural justice had a significant effect on OBSE, and both procedural justice and OBSE had significant effects on AOC. In addition, the results suggested that ethical CSR programs can have a positive impact on employees’ AOC via their procedural justice and OBSE. This study contributed to the literature by developing a CSR-procedural justice-OBSE-AOC model, guided by social exchange and self-consistency theories, and empirically testing it within a hospitality context.
