This study primarily aims to develop and solve an enhanced optimisation model for an assembly product multi-period inbound inventory routing problem (IRP). The many-to-one (inbound) model considers the bill of materials (BOM), supply failure risks (SFR) and customer demand uncertainty. The secondary objective is to study the influence of potential time-dependent model variables on the overall supply network costs based on a full factorial design of experiments (DOE).

A five-step solution approach is proposed to derive the optimal inventory levels, best sourcing strategy and vehicle route plans for a multi-period discrete manufacturing product assembly IRP. The proposed approach considers an optimal risk mitigation strategy by considering less risk-prone suppliers to deliver the required components in a specific period. A mixed-integer linear programming formulation was solved to derive the optimal supply network costs.

The simulation results indicate that lower demand variation, lower component price and higher supply capacity can provide superior cost performance for an inbound supply network. The results also demonstrate that increasing supply capacity does not necessarily decrease product shortages. However, when demand variation is high, product shortages are reduced at the expense of the supply network cost.

A two-echelon supply network for a single assembled discrete product with homogeneous vehicle fleet availability was considered in this study.

The proposed multi-period inbound IRP model considers realistic SFR, customer demand uncertainties and product assembly requirements based on a specific BOM. The mathematical model includes various practical aspects, such as supply capacity constraints, supplier management costs and target service-level requirements. A sensitivity analysis based on a full factorial DOE provides new insights that can aid practitioners in real-life decision-making.

The purpose of this paper is to explore the mediating role of internal reference price (IRP) in a pay-what-you-want (PWYW) price setting. Specifically, it examines the effects of altruism, social desirability and price consciousness as the antecedents of IRP and consumers’ willingness to pay (WTP), future purchase intention and attitude toward the seller as the outcomes of IRP.

The data for the study were collected from 272 respondents through a structured survey and analyzed through structural equation modeling technique using AMOS 22.0.

Altruism and social desirability positively influence IRP whereas price consciousness influences IRP negatively. IRP mediates the effects of altruism, social desirability and price consciousness on WTP, future purchase intention and attitude toward the seller.

PWYW pricing strategy can help attract consumers with self-less characteristics or a desire to behave in a socially appropriate manner but not those who are highly price conscious as reflected by the differences in the way in which their IRPs influence their WTP, future purchase intention and attitude toward the seller.

This paper introduces a parsimonious framework to explain how three consumer characteristics influence consumers’ pricing decisions in PWYW context. The finding that the effects of antecedent variables on WTP, attitude and future purchase intention are mediated by IRP provides new insights that have not been explored earlier.

The purpose of this paper is to explore the roles of the initial perceptions of chief audit executives (CAEs) on the role of internal audit function (IAF) in integrated reporting (IR) in South Africa. This paper draws attention to possible challenges and barriers to internal audit’s (IAs) involvement in the integrated reporting process (IRP).

Detailed interviews were carried out in 2016 with 10 CAEs from the EY Excellence in Integrated Reporting Awards for South Africa. An interpretive approach involving thematic content analysis was used to construct key themes which provided the CAE’s initial perception of the IAF’s role in IRP.

Despite the current role being limited, the findings suggest that the IAF has unexploited potential to improve the IRP. These roles include: providing assurance on data integrity; reviewing risks and opportunities; evaluating the adequacy of governance and risk management controls and giving assurance on the IRP. A benefit to the IAFs involvement in the IRP relates to their extensive knowledge of the business. The lack of skills in the IA profession is an area of concern, as there is a shortage of capacity and specialist skills.

The interpretive style will assist IAFs to understand and define their role in the IRP, as well as to follow best practice in the IRP.

This paper is the first to explore the views and make recommendations on the role of the IAF in the IRP. This paper can be seen as an important contribution to academic research as the role of IAF in the IRP is exploratory in a global context.

This study aims to extend prior studies by examining the mediation effects of sticker shock on the relationship between price discount and buying intention. Sticker shock refers to the discrepancy between a brand’s sale price (SP) and an individual’s internal reference price (IRP) (Winer 1985).

Prior marketing research on sticker shock is primarily model-based. The authors employed a between-subject experimental design, and hypotheses were tested using a series of regression functions (Baron and Kenny 1986).

The results suggest the effect of price discount on buying intention is partially mediated by sticker shock.

The research results suggest that consumers take into account price messages from different sources, such as advertised reference price, SP and IRP. IRP is a key reference point that consumers use to develop the “gain” or “loss” perception. Firms may apply different strategies to influence consumers’ internal reference point and, in turn, influence the perception of the attractiveness of the sale product.

This study contributes to the literature by first testing the mediation effects of sticker shock on the relationship between price discount and buying intention.

The purpose of this paper is to demonstrate the heterogeneous effects of gains and losses on the perception of new products. It seeks to argue that the heterogeneity in these effects (partly) stems from the price-perceived quality relationship which is more important for quality-seeking customers.

A multilevel logit model was applied to household panel data on purchases of new yoghurt and sausage products in Germany. The multilevel model allowed to estimate heterogeneous price effects and accounted for the nested structure in panel data.

Significant variation in the effects of gains, losses, and promotions were found. Internal reference prices (IRPs), which served as indicator of loss-averse vs quality-seeking customers, were found to moderate these effects. Monetary losses have less negative effects for customers with high IRPs. Negative interaction effects of IRPs with monetary gains and promotions indicate that quality-seeking customers are less attracted by gains and promotions.

The heterogeneity in the price effects confirms the strategic importance of new product prices to influence customers’ perception of value. The price-quality relationship is an explanatory approach for heterogeneous price effects and should not be neglected in price setting. The inclusion of customer-specific reference price information yields deeper insights into customers’ use of prices to evaluate new products.

This study is the first to estimate asymmetric gain and loss effects in the analysis of new product trial. A customer-specific view in price setting is emphasized by taking customer-specific reference prices into account.

This chapter describes and tests the principles of configural theory in the context of hospitality frontline service employees’ happiness-at-work and managers’ assessments of these employees’ quality of work performances. The study proposes and tests empirically a configural asymmetric theory of the antecedents to hospitality employee happiness-at-work and managers’ assessments of employees’ quality of work performance. The findings confirm and go beyond prior statistical findings of small-to-medium effect sizes of happiness-performance relationships. The method includes matching cases of data from surveys of employees (n = 247) and surveys completed by their managers (n = 43) and uses qualitative comparative analysis via the software program fsQCA.com. The findings support the four principles of configural analysis and theory construction: recognize equifinality of different solutions for the same outcome; test for asymmetric solutions; test for causal asymmetric outcomes for very high versus very low happiness and work performance; and embrace complexity. The theory and findings confirm that configural theory and research resolves perplexing happiness–performance conundrums. The study provides algorithms involving employees’ demographic characteristics and their assessments of work facet-specifics which are useful for explaining very high happiness-at-work and high quality-of-work performance (as assessed by managers) – as well as algorithms explaining very low happiness and very low quality-of-work performance.

This study aims to analyze the impact of family incivility (FI) on in-role performance (IRP) and proactive customer service performance (PCSP) via the mediating effect of emotional exhaustion (EE) and the moderating roles of emotional intelligence (EI) and mindfulness.

Hypotheses were verified using multisource and multiwave data collected from 337 valid hotel employee–supervisor dyads in Kuala Lumpur, Malaysia. Data were analyzed using SPSS 24.0, AMOS 24.0 and PROCESS (version 3.4).

FI intensified frontline employees’ (FLEs) EE, which subsequently impeded their IRP and PCSP. EI and mindfulness moderated the direct influence of FI on EE, IRP and PCSP and moderated the indirect influence of FI on the two aforementioned outcomes through EE.

Managers should observe FLEs’ indicators of FI and deter its emergence by implementing care programs for FLEs suffering from FI. In addition, human resource managers should preferentially recruit employees with high EI through related tests. Hotels can invite reputable psychologists to provide psychotherapy interventions for FLEs, such as mindfulness-based psychological lectures and therapy.

The hospitality literature lacks an understanding of the underlying process through which FI affects FLEs’ job outcomes. This study incorporates EE as a mediator of the FI’s impact on IRP and PCSP, and to the best of the authors’ knowledge, this study is the first to assess whether EI and mindfulness moderate the direct impact of FI on IRP and PCSP and the indirect impact of FI on two aforementioned outcomes via EE.

This industry viewpoint paper provides a comprehensive overview and critical viewpoint on the use of collectable toy premiums via instant reward programs (IRP) within the retail industry as a marketing tool.

This paper draws upon the uses of a “free” collectable toy premium promotion with a fixed purchase spend (via an IRP) in the supermarket industry as a marketing instrument to increase customer basket spend and repeat visits. Reflections on the recent use of toy premiums by Australian supermarket retailers are also utilised to highlight the ingredients for a successful promotion but also the controversies associated with such promotions.

One of the key findings suggest that the role of toy premiums is a successful marketing tool by retailers to increase customer total basket spending. However, notable points of caution regarding offering IRPs incorporating collectable toy premiums promotions are established, including environmental concerns and the social, ethical dilemma as to whether these promotions are indirectly targeted at children rather than adult consumers.

The findings have important implications for retailers to attract customer attention, increased market spend and repeat purchases through a desired collectable premium promotion (via an IRP).

This is the first paper to critically review the usage of collectable toy premiums within the supermarket retail industry.

Extant literature on pricing posits that consumers’ internal reference price (IRP) drives willingness to pay (WTP), when external pricing cues are available. This positive IRP-WTP relationship is further moderated by involvement and price consciousness. The purpose of this paper is to test how the IRP-WTP relationship will be moderated by involvement and price consciousness, albeit in the pay-what-you-want (PWYW) context. In the PWYW setting consumers can pay any amount of money (including nothing) and no external pricing cues are provided.

A survey was engaged to measure the key variables, and the data was analyzed using hierarchical multiple regression with spotlight analyses.

In the normal everyday pricing context, involvement strengthens the IRP-WTP relationship, while price consciousness weakens it. Contrary to this normal pricing wisdom, in the PWYW context, it was found that both involvement and price consciousness weaken the IRP-WTP relationship, thereby driving down consumers’ WTP.

Future studies should use experimental design to manipulate some of the independent variables used in the study, focus on the mediating processes that underlie PWYW decision-making and extend the findings in the context of wider demographics.

Managers should focus on segmentation, branding and product experiences to ensure higher returns of PWYW businesses.

This paper addresses lack of overall research in the PWYW area, and also addresses some key gaps left by extant research of Kim et al. (2009) that was published in the Journal of Marketing.

The purpose of this paper is to propose a research model in which work engagement (WE) mediates the influence of work social support on job satisfaction (JS), in-role performance (IRP), creative performance (CP) and extra-role performance (ERP).

Data were collected from cabin attendants via three surveys two weeks apart and their pursers. The aforesaid relationships were assessed through structural equation modeling.

In general, there is support for the preponderance of hypotheses. Specifically, WE completely mediates the impact of coworker support on JS and IRP, while the impact of supervisor support on CP is completely mediated by WE. WE partly mediates the effect of coworker support on CP and ERP. Furthermore, the effect of supervisor support on JS, IRP and ERP is partly mediated by WE.

Management should make sure that the work environment consists of supportive supervisors and coworkers who are trained on how they can enhance the cooperation and collaboration among employees. Management should also create an employee platform where cabin attendants can contribute to service delivery process by sharing their experiences arising from passenger requests and problems.

The study extends and contributes to the current service research by assessing the impact of WE simultaneously on three performance outcomes. The study adds to current knowledge by investigating the mediating mechanism linking work social support to the attitudinal and behavioral outcomes. The study also controls the threat of common method variance with at least two procedural remedies, which have been rarely used in the current service research.
