PublicationHotelplan berät neu mit KI – wollen das die Kunden überhaupt?(20 Minuten, 2024-07-18)Hotelplan setzt auf KI: Darum gehts Hotelplan setzt für Beratungen neu eine KI ein. So geht das Unternehmen mit möglichen KI-Falschaussagen um. Hotelplan-Mitarbeitende können bald auf eine neue KI zugreifen, die Beratungen in den Reisebüros schneller und präziser machen soll. So bleibe mehr Zeit für individuelle Beratungen, verspricht Hotelplan. Solange Hotelplan die KI-Beratung den Kunden nicht aufzwinge, sei das wohl eine gute Sache, sagt ein Experte der Fachhochschule Graubünden.

PublicationA Bayesian Stochastic Discount Factor for the Cross-Section of Individual Equity Options( 2024-02-16)We utilize Bayesian model averaging to estimate a stochastic discount factor (SDF) for single-stock options. A Bayesian model averaging SDF outperforms reduced-form benchmark models in-sample and out-of-sample in pricing option return anomalies and portfolios. We document that the SDF is dense in characteristics with the impliedrealized volatility spread, option return momentum, and jump risk emerging as the most likely included factors. Noteworthy, we find that (i) our results remain largely robust after controlling for transaction costs and (ii) characteristics linked to behavioral biases gain in importance for options with high retail trading volume.

PublicationAristotelian Rhetoric as a Driver of Moral Organizational Change How Logos, Pathos, and Ethos can Initiate, Scale Up, and Sustain Moral Change in Organizations( 2024-06-22)Driven by the ambition to transform their organization as a force for social good, a rising number of employees have started grassroots movements to drive positive change from within their workplace (Briscoe & Gupta, 2016; Scully & Segal, 2002; One Young World, 2022). Surprisingly, research examining how this rising phenomenon contributes to shaping organizational moral boundaries is still relatively scarce. In this paper, we build on the theoretical framework of organizational moral change by Solinger et al. (2020) and expand it by bringing in Aristotelian deliberative rhetoric. Specifically, we explain how logos, pathos, and ethos appeals enable each phase of a moral change process: 1) initiating, 2) scaling up, and 3) securing moral change (cf. Solinger et al., 2020, p.510). We argue that it is by opening up, widening, and integrating the moral space that rhetoric contributes to bringing about a moral change. Theoretically, anchoring our perspective in Aristotle’s moral philosophy, we demonstrate the importance of moral character in moving an organization and its members closer to the morally good life (Aristotle, 2004). Practically, our model offers a set of rhetorical tools that could be used to reduce moral muteness in companies and establish durable patterns of morality in companies.

PublicationService business in manufacturing companies - Identifying misconceptions and directing further research(Nova Southeastern University, 2010-09-06)Despite increasing interest in service business in manufacturing companies, the arguments for the transition from selling products to providing services still lacks theoretical robustness. By using eight focus groups with 45 participating companies, the following five misconceptions related to the economic and strategic arguments could be identified: the share of service revenue is an indicator for moving toward services, services are more profitable than products, service business is less volatile than product business, services are used for differentiating the total offering and service strategy creates sustainable competitive advantages. The reflection on these misconceptions guides further research and enriches the conceptualization of services in a manufacturing context.
