Keck, Natalija, Steffen R. Giessner, Niels Van Quaquebeke and Erika Kruijff (In press): When do followers perceive their leaders as ethical? A relational models perspective to normatively appropriate conduct, Journal of Business Ethics.
Abstract: In the aftermath of various corporate scandals, management research and practice have taken great interest in ethical leadership. Ethical leadership is referred to as “normatively appropriate conduct” (Brown et al. in Organ Behav Hum Decis Process 97(2):117–134, 2005), but the prescriptive norms that actually underlie this understanding constitute an open question. We address this research gap by turning to relational models theory (Fiske in Structures of social life: the four elementary forms of human relations, Free Press, New York, 1991), which contextualizes four distinct moralities in four distinct interactional norms (i.e., the relational models). We expect that the norms inherent in each model dictate the type of leader relationship that followers deem ethical. Specifically, we hypothesize that, for each norm, followers will perceive leaders as less ethical the more discrepant, i.e., the more incongruent, followers’ ideal relational norm is with the perceived norm that they attribute to their actual leader–follower interaction. We tested the respective incongruence hypothesis in a cross-sectional survey of 101 Dutch employees. Polynomial regression and surface response analyses provide support for the hypothesized incongruence effects in each of the four relational models, suggesting that normatively appropriate conduct should not be limited to caring (i.e., community-oriented) behaviors. Indeed, all four relational models can predict ethical leadership perceptions. We discuss the implications in the context of ethical leadership research and managerial practice.

Gerpott, Fabiola H., Niels Van Quaquebeke, Sofia Schlamp and Sven C. Voelpel (In press): An Identity Perspective on Ethical Leadership to Explain Organizational Citizenship Behavior: The Interplay of Follower Moral Identity and Leader Group Prototypicality, Journal of Business Ethics.
Abstract: Despite the proliferation of research on ethical leadership, there remains a limited understanding of how specifically the assumingly moral component of this leadership style affects employee behavior. Taking an identity perspective, we integrate the ethical leadership literature with research on the dynamics of the moral self-concept to posit that ethical leadership will foster a sense of moral identity among employees, which then inspires followers to adopt more ethical actions, such as increased organization citizenship behavior (OCB). We further argue that these identity effects should be more pronounced when leaders are perceived to be group prototypical, as their actions then speak louder to followers’ sense of identity. Two studies—a scenario experiment with 138 participants and a field study with 225 employees—provided support for our hypothesized moderated mediation model. Perceived ethical leadership positively affected OCB via followers’ moral identity but only under conditions of high perceived leader group prototypicality. We discuss how the identity pathway of ethical leadership can facilitate novel theorizing about moral transference. Our findings also suggest that, when hiring external ethical leaders or training internal managers, practitioners are well advised to consider that these individuals may only be effective in morally transforming followers when they are perceived as prototypical for the group.
van Gils, Suzanne, Niels Van Quaquebeke, Jan Borkowski and Daan van Knippenberg (In press): Respectful leadership: Reducing performance challenges posed by leader role incongruence and gender dissimilarity, Human Relations.
Abstract: We investigate how respectful leadership can help overcome the challenges for follower performance that female leaders face when working (especially with male) followers. Firstly, based on role congruity theory (Eagly & Karau, 2002), we illustrate the biases faced by female leaders. Secondly, based on research on gender (dis-)similarity, we propose that these biases should be particularly pronounced when working with a male follower. Finally, we propose that respectful leadership is most conducive to performance in female leader/male follower dyads compared to all other gender configurations. A multi-source field study (N = 214) provides partial support for our hypothesis. While our hypothesized effect was confirmed, respectful leadership seems to be generally effective for female leaders irrespective of follower gender, thus lending greater support in this context to the arguments of role congruity rather than gender dissimilarity.
Van Quaquebeke, Niels, Jan U. Becker, Niko Goretzki and Christian Barrot (In press): Perceived ethical leadership affects customer purchasing intentions beyond ethical marketing in advertising due to moral identity self-congruence concerns, Journal of Business Ethics.
Abstract: Ethical leadership has so far mainly been featured in the organizational behavior domain and, as such, treated as an intra-organizational phenomenon. The present study seeks to highlight the relevance of ethical leadership for extra-organizational phenomena by combining the organizational behavior perspective on ethical leadership with a classical marketing approach. In particular, we demonstrate that customers may use perceived ethical leadership cues as additional reference points when forming purchasing intentions. In two experimental studies (N = 601 and N = 336), we find that ethical leadership positively affects purchasing intentions because of customers’ concerns for moral self-congruence. We show this by means of both mediation and moderation analyses. Interestingly, the effect of perceived ethical leadership on purchasing intentions holds over and above the ethical advertising claims (e.g., cause-related marketing) that are commonly used in marketing. We conclude by discussing the possible ramifications of ethical leadership beyond its effects on immediate employees.

Ottemöller, Ole and Hanno Friedrich (In Press): Modelling change in supply-chain-structures and its effect on freight transport demand (available online), Transportation Research Part E: Logistics and Transportation Review.
Abstract: The paper introduces a model to determine possible impacts of changes in supply chain structures on freight transport demand. Examples are centralisation or vertical (des)integration within supply chains. The model first generates a population of establishments and commodity flows in space which is then manipulated according to different scenarios. It uses methods from transport planning and optimisation as well as scenario technique. To demonstrate its applicability a centralisation in food supply chain structures in Germany is analysed. The results show that a more educated discussion is needed for such changes since the range of possible impacts is large.

, Christian Tröster, Andrew Parker, Daan van Knippenberg and Ben Sahlmueller (In press): The Coevolution of Social Networks and Thoughts of Quitting, Academy of Management Journal.
Abstract: Research has shown that employees who occupy more central positions in their organization's network have lower turnover. As a result, scholars commonly interpret turnover as the consequence of social networks. Based on Conservation of Resources theory, we propose an alternative coevolution perspective that recognizes the influence of changes in individuals' social network position on their thoughts of quitting (the consideration of turnover), but also posits that thoughts of quitting shape individuals' agency in maintaining and changing their social network. Extending previous research, we predict that creation (dissolution) of both friendship ties and advice ties are negatively (positively) related to subsequent thoughts of quitting. We then develop and test the novel hypotheses that for friendship ties, thoughts of quitting are positively related to tie retention and negatively related to tie creation (leading to network stasis), whereas for advice ties thoughts of quitting are negatively related to tie retention and positively related to tie creation (leading to network churn). In a longitudinal network analysis that assessed 121 employees across three time points, we find support for our hypotheses that thoughts of quitting affect network changes, but do not find that network changes affect thoughts of quitting.

Schwarzmüller, Tanja, Prisca Brosi and Isabell M. Welpe (In press): Sparking Anger and Anxiety: Why Intense Leader Anger Displays Trigger Both More Deviance and Higher Work Effort in Followers, Journal of Business and Psychology, (published online first).
Abstract: While previous research has assumed that intense leader anger displays result in negative consequences, researchers have recently started to outline their potential for prompting followers to improve their performance. We explain these conflicting positions by demonstrating that leaders’ anger intensity positively affects both deviance and work effort through triggering anger and anxiety in followers. We conducted two critical incident studies, replicating our results with different methodologies and controlling for potential alternative explanations. In line with theories on reciprocal emotions, supervisor-directed deviance became more likely with higher leader anger intensity because followers reacted with correspondingly more anger. However, in line with theories on complementary emotions, leaders’ anger intensity was also positively related to followers’ work effort due to followers’ anxiety. These results were replicated when taking leaders’ anger appropriateness into account as a potential moderator of the deviance-related path and when controlling for followers’ feelings of guilt (an alternative explanation for followers’ work effort). Our paper provides evidence that intense anger displays increase followers’ work effort but also cautions leaders to show these, as the work effort caused by them is based on followers’ intimidation and likely to be accompanied by deviant reactions. By considering the affective reactions triggered in followers, our paper integrates diverging theoretical perspectives on followers’ reactions to leaders’ anger intensity. Moreover, it is one of the first to disentangle the interpersonal effects that different expressions of the same emotion may have.

Welpe (In press): Satisfied with the Job, But Not with the Boss: Leaders’ Expressions of Gratitude and Pride Differentially Signal Leader Selfishness, Resulting in Differing Levels of Followers’ Satisfaction, Journal of Business Ethics, (published online first).
Abstract: Setting out to understand the effects of positive moral emotions in leadership, this research examines the consequences of leaders’ expressions of gratitude and pride for their followers. In two experimental vignette studies (N = 261; N = 168) and a field study (N = 294), leaders’ gratitude expressions showed a positive effect and leaders’ pride expressions showed a negative effect on followers’ ascriptions of leader selfishness. Thereby, leaders’ gratitude expression indirectly led to higher follower satisfaction with and OCB towards the leader, while leaders’ pride expressions indirectly reduced satisfaction with and OCB towards the leader. Furthermore, leaders’ expressions of gratitude indirectly reduced followers’ intentions to leave the leader, while leaders’ expressions of pride indirectly fuelled them. Although ascriptions of selfishness consistently influenced these leader outcomes more strongly than comparable organizational outcomes, results on organizational outcomes were mixed. While leaders’ expressions of gratitude led, as expected, to higher job satisfaction and lower turnover intentions, leaders’ expressions of pride showed positive relations with both OCB towards the organization and intentions to leave the organization. We discuss the theoretical implications of leaders’ expressions of positive moral emotions as signals of outcome attributions, as well as leaders’ selfishness and practical implications that help leaders build followers’ satisfaction and positive leader–follower relationships.

Mölders, Sophie, Prisca Brosi, Matthias Spörrle and Isabell M. Welpe (In press): The Effect of Top Management Trustworthiness on Turnover Intentions via Negative Emotions: The Moderating Role of Gender, Journal of Business Ethics, (published online first).
Abstract: Based on a field study (N = 303), this paper explores the differential role that perceived top management trustworthiness has on female and male employees’ negative emotions and turnover intentions in organizations. A theoretical model is established that explicates a negative indirect effect of perceived top management trustworthiness on employee turnover intentions through employee negative emotions. The results reveal that there is a negative relationship between perceived top management trustworthiness and employee negative emotions and resulting turnover intentions and that this effect is stronger for female employees than for male employees. These results demonstrate the pivotal role played by top management trustworthiness, provide an explanation for the turnover gender gap, and highlight the subjectivity in reactions to trustworthiness perceptions. The implications for organizations are discussed in line with the need for top management to positively influence employees and particularly women, to retain them in their workforce.

Li, Hongyan and Joern Meissner (In press): Capacity optimization and competition with cyclical and lead-time-dependent demands, Annals of Operations Research.
Abstract: Capacity acquisition is often capital- and time-consuming for a business, and capacity investment is often partially or fully irreversible and difficult to change in the short term. Moreover, capacity determines the action space for service/production scheduling and lead-time quotation decisions. The quoted lead-time affects the customer’s perceived service quality. Thus, capacity acquisition level and lead-time quotation affect a firm’s revenue/profit directly or indirectly. In this paper, we investigate a joint optimization problem of capacity acquisition, delivery lead-time quotation and service-production scheduling with cyclical and lead-time-dependent demands. We first explore the structural properties of the optimal schedule given any capacity and lead-time. Then, the piecewise concave relationship between the delay penalty cost and the capacity acquisition level is found. Thereby, an efficient and effective polynomial time algorithm is provided to determine the optimal capacity acquisition level, delivery lead-time quotation and service/production schedule simultaneously. Furthermore, a capacity competition game among multiple firms is addressed. The numerical studies show that capacity equilibrium often exists and converges to a unique solution.
Turrini, Laura and Joern Meissner (In Press): Spare parts inventory management: New evidence from distribution fitting, European Journal of Operational Research.
Abstract: Spare parts are necessary for ensuring the functioning of the critical equipment of many companies, and as such, they play a central role in these companies’ operations. Inventory control of spare parts is particularly challenging due to the nature of their demand, which is usually slow-moving, erratic and lumpy. As inventory policies rely on the forecasted lead-time demand distribution and this choice impacts the performance of the system, an ill-suited hypothesized distribution may result in high preventable costs. In this study, we contribute to the empirical literature by analyzing what distributions best fit spare parts demand. We use the Kolmogorov Smirnov (K–S) goodness-of-fit test to find the best-fitting distributions to our data and compare our results to those in the literature. Furthermore, we implement a slightly modified K–S test that places greater emphasis on differences in the right tail of the distribution, mirroring real-world inventory applications, and less emphasis on the left tail. Finally, we link the goodness-of-fit of the distributions to their inventory performance. Our first dataset comes from the German renewable energy industry and is composed of the weekly demand for more than 4000 items over the period 2011–2013. The second dataset comes from the Royal Air Force. It is composed of monthly demand for 5000 items over the period 1996–2002.
Acciaro, Michele, Claudio Ferrari, Jasmine S. L. Lam, Rosario Macario, Athena Roumboutsos, Christa Sys, Alessio Tei and Thierry Vanelslander (2018): Are the innovation processes in seaport terminal operations successful? (published online first), Maritime Policy & Management, 45 (6): 787-802.
Abstract: The maritime and port sector is widely considered conservative concerning the ability to introduce innovation in respect to other industries. This may be due to the lack of cooperative interactions among the several players involved. It does not mean that innovation does not occur in this industry. Along with some technical innovations, managerial, organizational, and cultural innovations also take place in the sector. The literature has considered the assessment and effects of the adoption of particular innovation, but still few studies underline the innovation path in a broad sense with a specific focus on terminal operators. The present article aims at filling this gap through a field analysis grouping together case studies developed in different world regions and examining the adoption path of innovation through a mix of three different techniques (i.e. the H- and I-indexes, a Systems of Innovation Analysis, and a Qualitative Comparative Analysis). Research outcomes underline how, even if no unique recipe for success can be found, specific factors (e.g. a ranking of innovation objectives, coordination among actors, and institutions) can influence the achievement of success. The analyses allow suggesting strategic and policy advice that may help link in a better way the innovation drivers with their actual effects.

Dong, Chuanwen, Robert Boute, Alan C. McKinnon and Marc Verelst (2018): Investigating synchromodality from a supply chain perspective, Transportation Research Part D: Transport and Environment, 61 (Part A): 42-57.
Abstract: Greater use of multimodal transportation can substantially improve the environmental performance of freight transportation. Despite strenuous efforts by public policy-makers to alter the freight modal split, most companies still rely heavily on road transportation, and modal shifts to rail and water have remained modest at best. In this paper we argue that this is partly the result of a failure to take a holistic supply chain view of the modal shift process. Synchromodality provides a framework within which shippers can manage their supply chains more flexibly to increase the potential for shifting mode. On the basis of a literature review, we broaden the conventional focus of multimodal transportation to give it a supply chain dimension, and propose the concept of ‘Synchromodality from a Supply Chain Perspective’ (SSCP). Using a case study we show that when the supply chain impacts are taken into account, it is possible to significantly increase the share of intermodal rail transportation within a corridor, without necessarily increasing total logistics cost or reducing the service level. In this way the environmental impact of freight activities can be significantly reduced.
Reh, Susan, Christian Tröster and Niels Van Quaquebeke (2018): Keeping (future) rivals down: Temporal social comparison predicts coworker social undermining via future status threat and envy, Journal of Applied Psychology, 103 (4): 399-415.
Abstract: The extant social undermining literature suggests that employees envy and, consequently, undermine coworkers when they feel that these coworkers are better off and thus pose a threat to their own current status. With the present research, we draw on the sociofunctional approach to emotions to propose that an anticipated future status threat can similarly incline employees to feel envy toward, and subsequently undermine, their coworkers. We argue that employees pay special attention to coworkers' past development in relation to their own, because faster-rising coworkers may pose a future status threat even if they are still performing worse in absolute terms in the present. With a set of two behavioral experiments (N = 90 and N = 168), we establish that participants react to faster-rising coworkers with social undermining behavior when the climate is competitive (vs. less competitive). We extended these results with a scenario experiment (N = 376) showing that, in these situations, participants extrapolate lower future status than said coworker and thus respond with envy and undermining behavior. A two-wave field study (N = 252) replicated the complete moderated serial mediation model. Our findings help to explain why employees sometimes undermine others who present no immediate threat to their status. As such, we extend theorizing on social undermining and social comparison.
