(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)

(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.

(In press): From Action to Response to Effect: Mining Statistical Relations in Work Processes, Information Systems: 102035.
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.

(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.

(In Press): Offset or reduce: How should firms implement carbon footprint reduction initiatives?, Production and Operations Management: .
Abstract: Carbon emissions reduction initiatives have received considerable attention at the corporate level. Companies such as Daimler, Apple and Amazon have publicly declared their goal of becoming carbon neutral, or “net zero” in a near future. They are responding to a growing demand for sustainable products and services. Companies have a variety of options for carbon emission reductions available to them, including internal reductions such as adopting renewable energy, as well as buying carbon offsets. This raises the question of whether consumers perceive the different types of carbon emission reductions as equivalent, or whether they favor the implementation of internal measures. We investigate this issue empirically through surveys and incentive-compatible discrete choice experiments. We find clear consumer preferences and willingness to pay for companies to reduce their carbon footprint when companies internally reduce their controllable emissions rather than buying carbon offsets for these emissions, and it is especially true for eco-conscious consumers. Consumers place roughly the same value, however, to internal reductions in controllable emissions, and buying offsets for the same amount of uncontrollable emissions.
(2023): Data, analytical techniques and collaboration between researchers and practitioners in humanitarian health supply chains: a challenging but necessary way forward, Journal of Humanitarian Logistics and Supply Chain Management: .
Abstract: This paper aims to provide a discussion on the interface and interactions between data, analytical techniques and impactful research in humanitarian health supply chains. New techniques for data capturing, processing and analytics, such as big data, blockchain technology and artificial intelligence, are increasingly put forward as potential “game changers” in the humanitarian field. Yet while they have potential to improve data analytics in the future, larger data sets and quantification per se are no “silver bullet” for complex and wicked problems in humanitarian health settings. Humanitarian health supply chains provide health care and medical aid to the most vulnerable in development and disaster relief settings alike. Unlike commercial supply chains, they often lack resources and long-term collaborations to enable learning from the past and to improve further.
(2023): The Russia-Ukraine Outbreak and the Value of Renewable Energy, Economics Letters: .
Abstract: The paper studies the role of renewable energy in the stock market reaction to the Russia-Ukraine crisis. The examination of equity prices reveals that European firms with a larger share of ex-ante purchased or produced renewables experience less stock return decline in the Russia-Ukraine outbreak period.
(2023): Impact of pandemics on humanitarian retailing operations: A voucher´s case, Production and Operations Management, 32 (5): .
Abstract: In 2020, the world started a fight against a pandemic that has severely disrupted commercial and humanitarian supply chains. Humanitarian organizations (HOs), like the World Food Programme (WFP), adjusted their programs in order to manage this pandemic. One such program is cash and voucher assistance (CVA), which is used to bolster beneficiaries' freedom of choice regarding their consumption. In this vein, WFP supports local retailers to provide CVA to beneficiaries who do not have access to a functioning market. However, the operations of these stores can suffer from a very high transmission risk of COVID-19 unless preventive measures are put in place to reduce it. This paper discusses strategies that retailers and HOs can enact to maximize their service and dignity levels while minimizing transmission risk under a CVA program during a pandemic. We argue that HOs providing CVA programs can improve their assistance during a pandemic by implementing strategies that impact the retailing operations of their retailers.
(2023): Marvelous advertising returns? A meta-analysis of advertising elasticities in the entertainment industry, Journal of the Academy of Marketing Science: .
Abstract: How does advertising affect supply and demand in the entertainment industry? Different advertising and distribution mechanisms and unique product characteristics limit the transferability of findings from other industries to the entertainment industry. This meta-analysis focuses on 290 documented elasticities, drawn from 59 studies of movies and video games, and establishes new findings and empirical generalizations. First, the average advertising elasticity in the entertainment industry is .33 (method bias-corrected .20), approximately three times higher than the average identified for other industries. Second, average advertising elasticities are higher for demand (e.g., revenue) than for supply (e.g., screens). Third, elasticities of pre-launch advertising are higher than those of overall advertising budgets, but with respect to the success period, elasticities are higher for later periods, and in total, compared to the launch period. Fourth, elasticities tend to be rather recession-proof and consistent across geographic regions but decreased after the rise of social media platforms.

(2023): Supply chain preparedness: How operational settings, product and disaster characteristics affect humanitarian responses, Production and Operations Management: .
Abstract: Supply chains are dynamic and complex systems. This holds particularly true for humanitarian supply chains that operate under strong uncertainty. In view of an ever-growing gap of unmet humanitarian needs, it is essential to gain a better understanding of the behavior of humanitarian supply chain systems. Despite a growing academic output in this field, there is a lack of empirical studies that take an integrated view on humanitarian supply chains and support decision makers with fact-based evidence. Based on four extensive case studies and existing literature, we developed a system dynamics model that reflects the operational reality of humanitarian organizations in form of their centralized, hybrid and decentralized settings. The model provides a holistic supply chain view and measures the operational performance with regard to response cost, delivery lead time and impact on the local economy. Furthermore, we studied the impact of preparedness investments to enhance operational performance in the supply chain and deliver more humanitarian assistance with the limited resources available. Finally, we used our model to analyze the impact of major shocks such as the COVID-19 pandemic to assess the vulnerability of humanitarian supply chains. The results indicate that operational settings, product and disaster characteristics have a major influence on the supply chain performance both in the noninvestment case as well as in the case where preparedness investments have been made. Specifically, for low-value items, we find that decentralized settings have the lowest supply chain costs while for high-value items the price difference between local and international procurement determines which setting is the most cost-effective one. The preferability of the supply chain setting strongly depends on the indicator chosen. Hence, ultimately, the findings emphasize the need to apply appropriate indicators and identify their trade-offs to comprehensively analyze the performance of humanitarian supply chain settings. The newly introduced Humanitarian Return-on-Investment concept can play an important role in this context.
(2023): Can Capital Adjustment Costs Explain the Decline in Investment-Cash Flow Sensitivity?, Journal of Financial and Quanitative Analysis: .
Abstract: It is well documented that since at least the 1970s investment-cash flow (I-CF) sensitivity has been decreasing over time to disappear almost completely by the late 2000s. Based on a neoclassical investment model with costly external financing, we show that this pattern can be explained by the gradual increase of capital adjustment costs, attributable to the accumulation of knowledge capital. The result is robust to a variety of approaches, including Euler equation estimation and the simulated method of moments. More generally, our findings demonstrate that I-CF sensitivity should only be interpreted as a joint measure of financial and real frictions.
(2022): Supplier Inventory Leanness and Financial Performance, Journal of Operations Management, 68 (4): 385-407.
Abstract: Numerous studies have examined the relationship between inventory management and financial performance. However, the focus of such empirical work has primarily been on how a firm's own inventory characteristics affect its performance. Our objective is to extend this body of literature beyond the firm-level. We draw on inventory theory and resource-based theories to hypothesize about the effect of supplier inventory leanness on a focal firm's financial performance and how supplier and focal firm inventory leanness interact to affect such outcomes. We test our hypotheses using a large panel dataset of supplier-focal firm relationships obtained from Compustat's Customer Segment database and aggregated to the focal firm-quarter level, as well as firm financial information from Compustat's Fundamentals Quarterly database. The econometric analyses provide evidence that supplier inventory leanness influences focal firm financial performance indirectly through the interaction with the firm's own inventory leanness. In particular, our estimation results detail how supplier inventory leanness affects the non-linearity of the focal firm's inventory leanness-financial performance relationship and its optimal inventory leanness level. The findings broaden the scope of empirical inventory literature and highlight supplier inventory leanness as an important consideration in firm-level inventory decision making.
(2022): Transparency in port governance: setting a research agenda, Journal of Shipping and Trade, 7 (1): .
Abstract: This study examines the concept of transparency as practiced (or not) in ports. It explores the availability of information to the general public and port stakeholders through the ports’ most public face—its website, studying public ports in North America, Europe, and Latin America and the Caribbean. This exploratory research centred on identifying the parameters that would be useful for the general public to have sufficient information to monitor, review and in many cases, participate in the decision-making processes carried out by the port authority, irrespective of whether or not laws mandate such disclosure. Fifty-one items were identified for the examination of each port’s website, focusing primarily on four major categories: decision-making governance, port communications and accessibility, transparency in reporting and in port operational activities. Using nine items as proxies for the 51, the research reveals uneven levels of port transparency both regionally and by governance model. The study reveals a need for increasing and differentiating the existing levels and standards of transparency in the governance of the port industry, and for greater consistency between ports within and across regions. The study concludes with a research agenda for future research.
(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.
(2022): The impact of COVID-19 on music consumption and music spending, PLOS ONE, 17 (5): .
Abstract: COVID-19 induced restrictions ordered by governments around the world have been an exogenous shock to the music industry, which we divide into two affected groups: 1) live music events and 2) recorded music. While the impact on live music events is rather obvious, it is unclear how the current pandemic is affecting the recorded music market. Hence, we study consumers’ pre- and post-pandemic shifts in consumer spending (in euros) and music consumption (in hours) across live music events, as well as the digital and physical submarkets of recorded music, in the world’s fourth largest music market, Germany. Relying on an online bi-annual panel capturing five waves between winter 2018/19 and winter 2020/21, we find that the COVID-19 pandemic is accelerating the continuous trend towards digitalization of the music landscape with premium streaming being the biggest beneficiary. However, total monthly consumer spending on music decreased by more than 45% compared to pre-pandemic, with live music events and physical sales being the most severely affected. Surprisingly, music consumption in hours also decreased during the lockdown even though consumers spent more time at home.
