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)

Abstract: Various advanced systems deploy artificial intelligence (AI) and machine learning (ML) to improve demand forecasting. Supply chain planners need to become familiar with these systems and trust them, considering real-world complexities and challenges the systems are exposed to. However, planners have the opportunity to intervene based on their experience or information that the systems may not capture. In this context, we study planners’ adjustments to AI-generated demand forecasts. We collect a large amount of data from a leading AI provider and a large European retailer. Our dataset contains 30 million forecasts at the SKU-store-day level for 2019, plus variables related to products, weather, and holidays. In our two-phase analysis, we aim to understand the adjustments made by planners and the quality of these adjustments. Within each phase, we first identify the drivers of adjustments and their quality using random forest, a well-known ML algorithm. Next, we investigate the collective effects of the different drivers on the occurrence and the quality of the adjustments using a decision tree approach. We find that product characteristics such as price, freshness, and discounts are important factors when making adjustments. Large positive adjustments occur more frequently but are often inaccurate, while large negative adjustments are generally more accurate but fewer in number. Thus, planners do not contribute to accuracy on average. Our findings provide insights for the better use of human knowledge in judgmental forecasting.

Koorn, Jelmer J., Xixi Lu, Henrik Leopold and Hajo A. Reijers (In press): From Action to Response to Effect: Mining Statistical Relations in Work Processes, Information Systems.
Abstract: Process mining techniques are valuable to gain insights into and help improve (work) processes. Many of these techniques focus on the sequential order in which activities are performed. Few of these techniques consider the statistical relations within processes. In particular, existing techniques do not allow insights into how responses to an event (action) result in desired or undesired outcomes (effects). We propose and formalize the ARE miner, a novel technique that allows us to analyze and understand these action-response-effect patterns. We take a statistical approach to uncover potential dependency relations in these patterns. The goal of this research is to generate processes that are: (1) appropriately represented, and (2) effectively filtered to show meaningful relations. We evaluate the ARE miner in two ways. First, we use an artificial data set to demonstrate the effectiveness of the ARE miner compared to two traditional process-oriented approaches. Second, we apply the ARE miner to a real-world data set from a Dutch healthcare institution. We show that the ARE miner generates comprehensible representations that lead to informative insights into statistical relations between actions, responses, and effects.

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.

Bouchery, Yann, Johan Woxenius and Jan C. Fransoo (In press): Identifying the market areas of port-centric logistics and hinterland intermodal transportation, European Journal of Operational Research.
Abstract: Many port authorities have developed ambitious strategies to foster hinterland intermodal transportation. In addition, port-centric logistics, that is, the provision of distribution facilities and value-adding activities in the port area, has expanded in multiple ports. Obviously, such port-centric logistics may impact the operations in the hinterland substantially and could potentially reduce opportunities for intermodal transport in the hinterland. We analyze the interaction between port-centric logistics and hinterland intermodal transportation. We take a logistics service provider’s perspective and we include some key elements in the model, such as detention fees, extra handling, transport efficiency and empty container repositioning. We develop new analytical results identifying the optimal market areas of truck-only transportation, port-centric logistics and hinterland intermodal transportation. Our results show that tension between port-centric logistics and hinterland intermodal transportation is quite likely to happen in practice. We additionally study the use of continental containers as a way to reconcile port-centric logistics and hinterland intermodal transportation and we derive further results. We illustrate our results via an example and we highlight managerial insights.

Van Quaquebeke, Niels, Mojtaba Salem, Marius van Dijke and Ramon Wenzel (2022): Conducting organizational survey and experimental research online: From convenient to ambitious in study designs, recruiting, and data quality., Organizational Psychology Review.
Abstract: Conducting organizational research via online surveys and experiments offers a host of advantages over traditional forms of data collection when it comes to sampling for more advanced study designs, while also ensuring data quality. To draw attention to these advantages and encourage researchers to fully leverage them, the present paper is structured into two parts. First, along a structure of commonly used research designs, we showcase select organizational psychology (OP) and organizational behavior (OB) research and explain how the Internet makes it feasible to conduct research not only with larger and more representative samples, but also with more complex research designs than circumstances usually allow in offline settings. Subsequently, because online data collections often also come with some data quality concerns, in the second section, we synthesize the methodological literature to outline three improvement areas and several accompanying strategies for bolstering data quality. Plain Language Summary: These days, many theories from the fields of organizational psychology and organizational behavior are tested online simply because it is easier. The point of this paper is to illustrate the unique advantages of the Internet beyond mere convenience—specifically, how the related technologies offer more than simply the ability to mirror offline studies. Accordingly, our paper first guides readers through examples of more ambitious online survey and experimental research designs within the organizational domain. Second, we address the potential data quality drawbacks of these approaches by outlining three concrete areas of improvement. Each comes with specific recommendations that can ensure higher data quality when conducting organizational survey or experimental research online.

Sitkin, Niels Van Quaquebeke and Pisitta Vongswasdi (2022): Walking our evidence-based talk: The status of leadership development in business schools, Journal of Leadership and Organizational Studies, 29 (1).
Abstract: Academics have lamented that practitioners do not always adopt scientific evidence in practice, yet while academics preach evidence-based management (EBM), they do not always practice it. This paper extends prior literature on difficulties to engage in EBM with insights from behavioral integrity (i.e., the study of what makes individuals and collectives walk their talk). We focus on leader development, widely used but often critiqued for lacking evidence. Analyzing 60 interviews with academic directors of leadership centers at top business schools, we find that the selection of programs does not always align with scientific recommendations nor do schools always engage in high-quality program evaluation. Respondents further indicated a wide variety of challenges that help explain the disconnect between business schools claiming A but practicing B. Behavioral Integrity theory would argue these difficulties are rooted in the lack of an individually owned and collectively endorsed identity, an identity of an evidence-based leader developer (EBLD). A closer inspection of our data confirmed that the lack of a clear and salient EBLD identity makes it difficult for academics to walk their evidence-based leader development talk. We discuss how these findings can help facilitate more evidence-based leader development in an academic context.
Ruesch, Lea, Murat Tarakci, Maria Besiou and Niels Van Quaquebeke (2022): Orchestrating coordination among humanitarian organizations, Production and Operations Management.
Abstract: Disasters mobilize hundreds of humanitarian organizations. Despite the common aim to assist beneficiaries, coordination among humanitarian organizations remains a challenge. This is why the United Nations has formed clusters to facilitate information and resource exchange among humanitarian organizations. Yet, coordination failures in prior disasters raise questions as to the effectiveness of the cluster approach in coordinating relief efforts. To better understand barriers to coordination, we developed a grounded theory and augmented the theory with an agent-based simulation. Our theory discerns a cluster lead’s roles of facilitating coordination but also investing in its own ground operations. We find that specifically serving such a dual role impairs trust and consequent coordination among cluster members. The additional simulation findings generalize the detrimental effect of the cluster lead’s dual role versus a pure facilitator role and specifies it against various boundary conditions.
Brosi, Prisca and Fabiola H. Gerpott (2022): Stayed at home - but can´t stop working despite being ill? Guilt as a driver of presenteeism at work and at home, Journal of Organizational Behavior.
Abstract: We argue that the literature on presenteeism needs to consider that employees not only go to work despite being ill but also often work from home despite being ill, especially since the COVID-19 crisis enabled home-office work on a large scale. We label this phenomenon “workahomeism” and develop theory that shows its distinctness from traditional presenteeism through the evoked pattern of guilt. Across three studies (a vignette experiment, a critical incident study, and a within-person intervention study), we tested whether employees' work-related reactions to illness (i.e., workahomeism, presenteeism, and resting at home) differ in terms of experienced and anticipated guilt. We found that when employees considered engaging in workahomeism, they anticipated feeling less guilty than when resting at home. However, when employees actually engaged in workahomeism, they felt as guilty or even more guilty than when resting at home. In contrast, employees' anticipated guilt for presenteeism as compared to workahomeism changed from the same to more after the beginning of the COVID-19 crisis. Furthermore, we identify facets of guilt in response to workahomeism (i.e., guilt toward colleagues and about own health) and demonstrate that organizations can change guilt patterns by asking employees to reflect on the consequences of workahomeism and presenteeism.
Lugovoi, Ivan, Dimitrios A. Andritsos and Claire Senot (2022): Manufacturing Process Innovation in the Pharmaceutical Industry, Manufacturing & Service Operations Management, 24 (3): 1261-1885.
Abstract: Problem definition: Process innovation is commonly claimed to be a major source of competitive advantage for firms. Despite this perceived influence, it has received substantially less attention than product innovation, and much uncertainty remains about its true association with firm performance. We investigate the relationship between a pharmaceutical firm’s portfolio of manufacturing process innovations and its economic performance. Academic/practical relevance: We uniquely conduct a multidimensional evaluation of a firm’s portfolio of manufacturing process innovations at the product level. This allows a quantitative evaluation of both the relative benefit of the different dimensions of a portfolio as well as the potential complementarities between these in different technological landscapes. Methodology: Through a collaboration with expert patent attorneys, we develop a unique longitudinal data set that combines secondary data and evaluations of a firm’s portfolio of process patents along two key dimensions: novelty and scope. We conduct econometric analyses for a large-scale sample of active pharmaceutical ingredients (APIs) whose product patents have expired and for which process innovation is thus the main source of competitive advantage. Results: We find a positive association between the presence of manufacturing process innovation and firm performance. However, although portfolio’s scope appears to always be beneficial to performance, the effect of novelty alone depends on the ruggedness of the technological landscape: negative in smoother landscapes and positive in more rugged landscapes. Results further suggest that novelty and scope of a portfolio of process innovations are complementary across technological landscapes. Managerial implications: Our results provide important practical insights that can inform the organization and execution of the research and development process across high-technology industries. In particular, although process innovations can be economically beneficial, investing in high-novelty process innovations without a corresponding high scope could jeopardize payoffs, especially in technological landscapes that are relatively smooth.
Lugovoi, Ivan, Dimitrios A. Andritsos and Claire Senot (2022): Novelty and scope of process innovation: The role of related and unrelated manufacturing experience, Production and Operations Management.
Abstract: The accumulation of experience that occurs with production is likely to impact an organization's ability to develop manufacturing process innovations. However, how different types of manufacturing experience relate to the characteristics of an organization's process innovation output is an open question. In this study, we investigate how a firm's accumulated related and unrelated manufacturing experiences are associated with this firm's ability to innovate its production methods. To characterize firms' process innovation output, we observe their portfolios of patented manufacturing inventions, which we qualitatively evaluate over time, through a unique collaboration with expert patent attorneys, along two critical dimensions: novelty and scope. We argue that related manufacturing experience leads to a better understanding of parts of the focal product's technological landscape that will allow the development of inventions of broader scope. However, it may also contribute to inertia in that it might restrict the firm's innovative activity to more familiar regions of the landscape, thereby limiting inventions' novelty. Conversely, manufacturing experience with products that are unrelated to the focal product is expected to stimulate and support a broader search that includes more distant regions of the focal product's technological landscape, which would lead to more novel manufacturing inventions. Yet, the application of this unrelated experience to the production of the focal product is likely to require additional exploratory effort in a not-well-understood region of the focal product's landscape, likely resulting in inventions of limited scope. In line with our hypotheses, we find that related (unrelated) manufacturing experience is positively (negatively) associated with inventions' scope, and negatively (positively) associated with inventions' novelty. In addition to supporting the relevance of a multidimensional evaluation of innovations, our findings provide practical guidance regarding the strategic implications of a firm's knowledge management.
