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.

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.
Brockhaus, Sebastian, Moritz Petersen and A. Michael Knemeyer (In press): The fallacy of “trickle-down” product sustainability: Translating strategic sustainability targets into product development efforts, International Journal of Operations & Production Management.
Abstract: Purpose The purpose of this paper is to explore how big-picture sustainability strategies are translated into tangible product development efforts. The authors assert that most sustainable products currently remain confined to niche markets and do not permeate the mainstream. The authors propose that there is a missing link between strategic sustainability goals and operational product development initiatives. The authors establish a path to bridging this gap. Design/methodology/approach The manuscript is based on a qualitative research design with a sample of 32 companies. Data were collected from semi-structured interviews with product developers as well as secondary data analysis. Findings The authors delineate three empirically derived approaches firms from the sample pursue to develop sustainable products. The authors identify a phenomenon that the authors’ call the fallacy of trickle-down product sustainability. The authors find that only one of the three approaches – codification – is equipped to successfully turn strategic sustainability targets into authentic sustainable products. Practical implications This study provides an actionable guide to executives and product developers with respect to bridging the gap between often elusive sustainability aspirations and tangible product improvements via the process of rigorous codification. Originality/value This study provides a novel and unique perspective into strategy, sustainability and product development. The authors synthesize the extant literature on sustainable product development, juxtapose the emergent structure with primary interview data, and elaborate the resource-based view (RBV) to provide theoretical and practical implications. The authors establish scalability as the missing RBV capability of many attempts toward mass–market compatibility of more sustainable products.

Heinen, Jakob and Kai Hoberg (In press): Assessing the Potential of Additive Manufacturing for the Provision of Spare Parts, Journal of Operations Management.
Abstract: Spare parts are a particularly interesting application for switching production from traditional manufacturing (TM) to additive manufacturing (AM). Research assessing AM has primarily addressed cost models centering on the production process or the operations management of separate spare parts. By combining case study, modelling, and design science elements, we adopt a holistic perspective and develop a design to examine the systematic leverage of AM in spare parts operations. Contextually grounded in problems faced by a leading material handling equipment manufacturer that is challenged by common characteristics of after-sales operations, we engage with practice to propose a portfolio level analysis examining the switchover share from TM to AM. Using a dataset of 53,457 spare parts over nine years, we find that up to 8% of stock keeping units (SKUs) and 2% of total units supplied could be produced using AM, even if unit production costs are four times those of TM. This result is driven by low demand, high fixed costs, and minimum order quantities in TM. Finally, we present the evaluation by the case company's management and highlight five areas of opportunity and challenge.

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.

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.
Abhishek, Boon, Marko A. A., Michel Mandjes and Rudesindo Núñez-Queija (In press): Congestion analysis of unsignalized intersections: The impact of impatience and Markov platooning, European Journal of Operational Research.
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)

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.

Badorf, Florian and Kai Hoberg (In press): The impact of daily weather on retail sales: an empirical study in brick-and-mortar stores, Journal of Retailing and Consumer Services.
Abstract: In this study, we examine the influence of weather on daily sales in brick-and-mortar retailing using empirical data for 673 stores. We develop a random coefficient model that considers non-linear effects and seasonal differences using different weather parameters. In the ex-post analysis using historic weather data, we quantify the explanatory power of weather information on daily sales, identify store-specific effects and analyze the influence of specific sales themes. We find that the weather has generally a complex effect on daily sales while the magnitude and the direction of the weather effect depend on the store location and the sales theme. The effect on daily sales can be as high as 23.1% based on the store location and as high as 40.7% based on the sales theme. We also find that the impact of extreme bad and good weather occurrences can be misestimated by traditional models that do not consider non-linear effects. In the ex-ante analysis, we analyze if weather forecasts can be used to improve the daily sales forecast. We show that including weather forecast information improves sales forecast accuracy up to seven days ahead. However, the improvement of the forecast accuracy diminishes with a higher forecast horizon.

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.
Petersen, Moritz (In press): How Corporate Sustainability Affects Product Developers’ Approaches Toward Improving Product Sustainability, IEEE Transactions on Engineering Management.
Abstract: Human factors, such as an individual's competences and attitudes, have a decisive impact on the results of product development processes, especially in companies with small product development teams. Sustainability considerations further amplify this impact as such a multifaceted issue results in an extra layer of product requirements and hard-to-make decisions on tradeoffs. This paper explores the interplay of corporate sustainability and the individual approaches product developers exhibit toward improving product sustainability. For this purpose, a grounded theory study in the German consumer goods industry is conducted. Thirty-two expert interviews with product development managers and extensive secondary data are collected and analyzed. It is found that the corporate sustainability approach heavily influences how developers comprehend sustainability and how they conceptualize it for their product portfolio. Explicitly, the products considered for sustainability improvements, their innovation level, and the use of design stereotypes to signal sustainability improvements emerge as key decision levers. The findings emphasize that the human factors in the context of product development, specifically concerning sustainability, warrant more academic attention. Also, it is demonstrated that companies need to be aware of the organizational environment which they are providing for their developers when pushing for product sustainability.

Meuer, Johannes, Christian Tröster, Michèle Angstmann, Uschi Backes-Gellner and Kerstin Pull (In press): Embeddedness and the repatriation intention of assigned and self-initiated expatriates, European Management Journal.
Abstract: Expatriation research has been intrigued by the question of how to prevent the unplanned return of expatriates to their home country. Although a majority of studies have focused on assigned expatriates (AEs), only recently have researchers expanded the scope of analysis by focusing on self-initiated expatriates (SIEs). For SIEs, research has identified job embeddedness as a key explanatory concept for early repatriation without yet acknowledging its potential to also explain the early expatriation of AEs. However, because AEs and SIEs differ in important motivational and behavioral aspects, the lack of comparative studies prohibits a deeper understanding of the mechanisms through which job embeddedness influences early repatriation. We build on belongingness theory to conceptualize early repatriation as a compensatory reaction of expatriates to an inhibited need to belong. Using a unique sample of 345 expatriates from 40 countries, we show that off-the-job embeddedness is more important for explaining the repatriation intention of AEs than of SIEs, whereas on-the-job embeddedness is more important for explaining the repatriation of SIEs compared to AEs. Our integrative model carries important theoretical implications for expatriation research and provides managerial implications for recruiting and retaining AEs and SIEs.
