    Chief strategy officers: Contingency analysis of their presence in top management teams
    (Wiley, 2014-03) Menz, Markus; Scheef, Christine
    Drawing upon contingency theory, we analyze the antecedents and performance consequences of chief strategy officer ( CSO ) presence in top management teams ( TMTs ). We argue that strategic and structural complexity affects the decision to have a CSO in the TMT and its effect on firm performance. The results of a sample of S&P 500 firms over a five‐year period reveal that diversification, acquisition activity, and TMT role interdependence are positively associated with CSO presence. However, we also find that the structural choice to have a CSO in the TMT does not significantly affect a firm's financial performance. This first systematic analysis of CSO presence informs research on CSOs and contributes to the emerging literature on TMT structure . Copyright © 2013 John Wiley & Sons, Ltd.

    Advanced therapy medicinal products are coming of age: A pipeline analysis of the clinical trial landscape
    (Elsevier, 2025-08) Vanhaeren, Michiel; Gijsbers, Rik; Van Dyck, Walter; Huys, Isabelle; Simoens, Steven
    Advanced therapy medicinal products (ATMPs) are a unique class of biological medicines that are based on cells, genes, or tissues. Searching four databases, this analysis identified 2008 trials that investigated ATMPs and characterised them according to various characteristics, such as the sponsor type and phase of clinical development. This characterisation revealed that the market for ATMPs is maturing in terms of the number of products in development, the diseases being targeted, and the technologies being pursued. This characterisation is meant to help further the discussion on the ever-growing clinical trial landscape of ATMPs and inform healthcare payers.

    Optimal robust inventory management with volume flexibility: Matching capacity and demand with the lookahead peak‐shaving policy
    (SAGE Publications, 2023-11) Gijsbrechts, Joren; Imdahl, Christina; Boute, Robert; Van Mieghem, Jan A
    We study inventory control with volume flexibility: A firm can replenish using period‐dependent base capacity at regular sourcing costs and access additional supply at a premium. The optimal replenishment policy is characterized by two period‐dependent base‐stock levels but determining their values is not trivial, especially for nonstationary and correlated demand. We propose the Lookahead Peak‐Shaving policy that anticipates and peak shaves orders from future peak‐demand periods to the current period, thereby matching capacity and demand. Peak shaving anticipates future order peaks and partially shifts them forward. This contrasts with conventional smoothing, which recovers the inventory deficit resulting from demand peaks by increasing later orders. Our contribution is threefold. First, we use a novel iterative approach to prove the robust optimality of the Lookahead Peak‐Shaving policy. Second, we provide explicit expressions of the period‐dependent base‐stock levels and analyze the amount of peak shaving. Finally, we demonstrate how our policy outperforms other heuristics in stochastic systems. Most cost savings occur when demand is nonstationary and negatively correlated, and base capacities fluctuate around the mean demand. Our insights apply to several practical settings, including production systems with overtime, sourcing from multiple capacitated suppliers, or transportation planning with a spot market. Applying our model to data from a manufacturer reduces inventory and sourcing costs by 6.7%, compared to the manufacturer's policy without peak shaving.

    Rage Against the Machine: Experimental Insights into Customers’ Negative Emotional Responses, Attributions of Responsibility, and Coping Strategies in Artificial Intelligence–Based Service Failures
    (SAGE Publications, 2023-02) Pavone, Giulia; Meyer-Waarden, Lars; Munzel, Andreas
    In their interactions with chatbots, consumers often encounter technology failures that evoke negative emotions, such as anger and frustration. To clarify the effects of such encounters, this article addresses how service failures involving artificial intelligence–based chatbots affect customers’ emotions, attributions of responsibility, and coping strategies. In addition to comparing the outcomes of a service failure involving a human agent versus a chatbot (Study 1), the research framework integrates the potential influences of anthropomorphic visual cues and intentionality (Studies 2 and 3). Through three experimental designs, the study reveals that when interacting with chatbots, customers blame the company more for the negative outcome, experiencing mainly frustration, compared with when they interact with a human agent. As the chatbot is perceived as not having intentions and control over them, it is not considered responsible. Thus, the company bears more responsibility for the poor service performance. However, the authors suggest that anthropomorphic visual cues might help mitigate the negative attributions to the company. The attribution of humanlike characteristics also helps promote both problem-focused coping, which helps consumers actively handle the service failure, and emotion-focused coping, which helps restore the emotional balance disrupted by the negative event.

    Le marketing relationnel
    (CAIRN, 2021-08-18) Munzel, Andreas
    Le paysage concurrentiel et les économies volatiles qui marquent le monde moderne signifient qu’il n’y a pas moyen de contourner la nécessité de gérer les clients de manière rentable à long terme. Il s’agit d’une question plus pressante que jamais. Les données sont facilement accessibles, à tel point que les entreprises sont souvent dépassées et manquent de compétences en interne pour faire face à cette explosion d’informations. De nouvelles tendances, telles que l’essor des médias sociaux et des applications, se développent alors pour créer de nouveaux défis de marketing relationnel pour les entreprises.Ce chapitre présente le marketing relationnel et expose les principaux facteurs qui influencent les approches relationnelles dans les entreprises. Il présente également une stratégie de gestion centrée sur le client et montre comment l’évolution du marketing relationnel rend possible une nouvelle compréhension du consommateur. Nous verrons ensuite comment le marketing relationnel et les principes de centralité du client façonnent les processus relationnels entre consommateurs et entreprises, depuis leur acquisition et intégration, en passant par la fidélisation et la formation des clients, jusqu’à leur récupération et la fin de la relation.Objectifs Considérer le marketing relationnel comme une source importante d’avantages concurrentiels durables pour les entreprises, avec une pertinence croissante dans le monde d’aujourd’hui. Définir le marketing relationnel et la gestion stratégique de la relation client et identifier les différences conceptuelles entre le marketing relationnel et d’autres stratégies…
