Abstract: This paper considers an unsignalized intersection used by two traffic streams. The first stream of cars is using a primary road, and has priority over the other stream. Cars belonging to the latter stream cross the primary road if the gaps between two subsequent cars on the primary road are larger than their critical headways. A question that naturally arises relates to the capacity of the secondary road: given the arrival pattern of cars on the primary road, what is the maximum arrival rate of low-priority cars that can be sustained? This paper addresses this issue by considering a compact model that sheds light on the dynamics of the considered unsignalized intersection. The model, which is of a queueing-theoretic nature, reveals interesting insights into the impact of the user behavior on the capacity. The contributions of this paper are threefold. First, we introduce a new way to analyze the capacity of the minor road. By representing the unsignalized intersection by an appropriately chosen Markovian model, the capacity can be expressed in terms of the solution of an elementary system of linear equations. The setup chosen is so flexible that it allows us to include a new form of bunching on the main road that allows for dependence between successive gaps, which we refer to as Markov platooning; this is the second contribution. The tractability of this model facilitates studying the impact that driver impatience and various platoon formations on the main road have on the capacity of the minor road. Finally, in numerical experiments we observe various surprising features of the aforementioned model. (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.

Mendling, Jan, Jan Recker, Hajo A. Reijers and Henrik Leopold (In press): An Empirical Review of the Connection Between Model Viewer Characteristics and the Comprehension of Conceptual Process Models, Information Systems Frontiers.
Abstract: Understanding conceptual models of business domains is a key skill for practitioners tasked with systems analysis and design. Research in this field predominantly uses experiments with specific user proxy cohorts to examine factors that explain how well different types of conceptual models can be comprehended by model viewers. However, the results from these studies are difficult to compare. One key difficulty rests in the unsystematic and fluctuating consideration of model viewer characteristics (MVCs) to date. In this paper, we review MVCs used in prominent prior studies on conceptual model comprehension. We then design an empirical review of the influence of MVCS through a global, cross-sectional experimental study in which over 500 student and practitioner users were asked to answer comprehension questions about a prominent type of conceptual model - BPMN process models. As an experimental treatment, we used good versus bad layout in order to increase the variance of performance. Our results show MVC to be a multi-dimensional construct. Moreover, process model comprehension is related in different ways to different traits of the MVC construct. Based on these findings, we offer guidance for experimental designs in this area of research and provide implications for the study of MVCs.

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.

Tröster, Christian, 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.
Merkle, Christoph (In press): Financial Loss Aversion Illusion, Review of Finance.
Abstract: Abstract: We test the proposition that investors' ability to cope with financial losses is much better than they expect. In a panel survey of investors from a large bank in the UK, we ask for their subjective ratings of anticipated returns and experienced returns. The time period covered by the panel (2008-2010) is one where investors experienced frequent losses and gains in their portfolios. This period offers a unique setting to evaluate investors' hedonic experiences. We examine how the subjective ratings behave relative to expected portfolio returns and experienced portfolio returns. Loss aversion is strong for anticipated outcomes; investors are twice as sensitive to negative expected returns as to positive expected returns. However, when evaluating experienced returns, the effect diminishes by more than half and is well below commonly found loss aversion coefficients. This suggests that a large part of investors' financial loss aversion results from an affective forecasting error.
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.

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.

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.
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.
Badorf, Florian, Stephan M. Wagner, Kai Hoberg and Felix Papier (In press): How Supplier Economies of Scale Drive Supplier Selection Decisions, Journal of Supply Chain Management.
Abstract: Supplier selections are complex but nonetheless strategically important decisions that are influenced by numerous factors. Drawing on the resource-based and relational view of the firm, we investigate how suppliers’ economies of scale influence the buyer’s selection decision, and we illustrate how the influence of scale is contingent upon important economic, buyer, and relationship characteristics. We test the model with a large secondary dataset of actual supplier selection decisions from the automotive industry and show that economies of scale have a strongly positive but diminishing effect on the buying firm’s supplier selection decision. These effects are reinforced or extenuated by economic, buyer, and relationship characteristics, with characteristics that are more specific to the buyer-supplier situation (e.g., relationship duration and power balance) having a stronger moderating effect than do characteristics that are more global (e.g., economic cycle). Our research helps suppliers to better understand how to manage selection probabilities with buyers and provides buying firms with a better understanding of how contextual factors affect the benefit of supplier-provided economies of scale.
Legros, Benjamin, Yann Bouchery and Jan C. Fransoo (In press): A Time-based Policy for Empty Container Management by Consignees, Production and Operations Management.
Abstract: Despite the many advantages of containerization for goods transportation, the management of empty containers is a major disadvantage, driving costly repositioning operations. We investigate the potential for consignees to manage an inventory of empty containers at their location so as to enable direct reuse of these containers by consignors located in the surroundings. One difficulty is that the detention fees imposed by shipping companies under merchant haulage are nonlinear. Moreover, cleaning and related activities might be necessary if the consignee keeps some empties. These difficulties incentivize consignees to immediately return containers to the sea terminal. Contrary to this practice, we show that managing containers via time-based threshold policies can save costs. Without cleaning costs, we prove that a time-based policy with a timeout return time is optimal. We next develop a policy improvement approach to include the cleaning costs in the analysis. This results in a two-thresholds time based policy where the two time thresholds control the admission into and rejection out of the inventory. We next analyze the impact of this proactive management on the level of direct container reuse. This practice enables a high level of direct reuse. It also reduces container repositioning costs. Yet, the incentive to implement our policy varies a lot from one setting to another. In particular, low cleaning costs or high repositioning costs lead to significant costs improvement when implementing our policy. Finally, we further explore if the incentive could be made stronger by modifying the structure and/or purpose of the detention costs.
Gawor, Tobias and Kai Hoberg (2019): Customers’ valuation of time and convenience in e-fulfillment, International Journal of Physical Distribution & Logistics Management, 49 (1): 75-98.
Abstract: The purpose of this paper is to derive monetary benchmarks and managerial implications for omni-channel retailers’ B2C e-fulfillment strategies by investigating the trade-offs between lead time, delivery convenience and total price including shipment in the context of online electronics retailing. Based on a choice-based conjoint analysis among 550 US online shoppers, the monetary values of lead time and convenience were calculated in a log-log regression model. In addition, latent class segmentation was applied to identify consumer segments according to their differing e-fulfillment preferences. From a consumer perspective, the analysis suggests that price is the most important criteria in omni-channel retailer selection, followed by lead time and convenience. The value of time is, on average, $3.61 per day. Regarding convenience, the results indicate that delivery to the home is highly preferred over pick-up options. The value of the consumer’s travel time was estimated at $10.62 per hour. The latent class segmentation identified four segment groups with different preferences.

Schätter, Frank, Ole Hansen, Markus Wiens and Frank Schultmann (2019): A decision support methodology for a disaster-caused business continuity management, Decision Support Systems, 118: 10-20.
Abstract: Supply chain risk management typically deals with the systematic identification, analysis and mitigation of risks which affect the whole supply chain network of a company. Business continuity management (BCM) forms part of supply chain risk management and is an important competitive factor for companies by ensuring the smooth functioning of critical business processes in the case of failures. If business operations are severely disrupted, the companies’ decision maker is confronted with a situation which is characterized by a high degree of uncertainty, complexity and time pressure. In such a context, decision support can be of significant value. This article presents a novel decision support methodology which leads to an improved and more robust BCM for severe disruptions caused by disasters. The methodology is part of the Reactive Disaster and supply chain Risk decision Support System (ReDRiSS) to deal with different levels of information availability and to provide decision makers with a robust decision recommendation regarding resource allocation problems. It combines scenario techniques, optimization models and approaches from decision theory to operate in an environment characterized by sparse or lacking information and dynamic changes over time. A simulation case study is presented where the methodology is applied within the BCM of a food retail company in Berlin that is affected by a pandemic disaster.
