PublicationRolling-out company-specific production systems in multinational corporations – a multilateral network perspective( 2024-07)Company-specific production systems (XPS) have recently seen a surge of attention in industry, due to their potential to yield substantial performance improvements. Their implementation however represents a complex process that needs to be managed thoroughly to avoid potential pitfalls. This exploratory study provides a holistic overview on how to manage the roll-out of XPS in multi-plant networks of multinational corporations (MNCs), adding to the understanding of this phenomenon. Investigating the XPS roll-out in the pharmaceutical industry, this multiple-case study yields two major findings. First, companies roll-out their XPS in a deliberate sequence or create an emerging sequence through pull mechanisms. Second, site resource availability is a key determinant of the deliberate sequence. The study follows the call for more research on XPS from a headquarter perspective and extends current research beyond the bilateral headquarter-site perspective, taking a multilateral network perspective. Finally, it provides practical insights that help XPS managers in defining their roll-out roadmaps.

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.

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.
