Data (r)evolution - the economics of algorithmic search and recommender services. - Ilmenau : Ilmenau University of Technology, Institute of Economics, 2021. - 1 Online-Ressource (33 Seiten). - (Ilmenau economics discussion papers ; vol. 27, no. 148)
The paper analyses the economics behind algorithmic search and recommender services, based upon personalized user data. Such services play a paramount role for online services such as marketplaces (e.g. Amazon), audio streaming (e.g. Spotify), video streaming (e.g. Netflix, YouTube), app stores, social networks (e.g. Instagram, Tik Tok, Facebook, Twitter) and many more. We start with a systematic analysis of search and recommendation services as a commercial good, highlighting the changes to these services by the systematic use of algorithms. Then we discuss benefits and risk for welfare arising from the widespread employment of algorithmic search and recommendation systems. In doing so, we summarize the existing economics literature and go beyond its insights, including highlighting further research desires. Eventually, we derive regulatory and managerial implications drawing on the current state of academic knowledge.

Wettbewerb und Antitrust in Unterhaltungsmärkten. - Ilmenau : Technische Universität Ilmenau, Institut für Volkswirtschaftslehre, 2021. - 1 Online-Ressource (46 Seiten). - (Diskussionspapier ; Nr. 147)
Dieser Beitrag fasst die ökonomischen Besonderheiten von Unterhaltungsmärkten zusammen und legt dabei einen besonderen Fokus auf Digitalisierungseffekte. Dabei werden die Aspekte Erfahrungsgüter und Qualität, Fixkostendegression & Güterheterogenität, Super-stareffekte, die Rolle (digitaler) Medien, sowie Preis- und Geschäftsmodelle diskutiert. Ein wesentliches Ergebnis der Betrachtung ist, dass Unterhaltungsmärkte im digitalen Zeitalter anfällig werden für typische Wettbewerbsbeschränkungen in digitalen Ökosystemen. Die Autoren unterstreichen diesen Befund mit einer Auswahl an relevanten und aktuellen Wettbewerbsproblemen und -fällen. Dabei zeigt sich, dass (i) die prowettbewerbliche Wirkung der Digitalisierung auf Medienmärkte fragil ist und des aktiven wettbewerbspolitischen Schutzes bedarf, (ii) nicht-horizontale Verflechtungen in digitalen Ökosystemen erhebliche Anreize zu behinderungswettbewerblichen Strategien wie Selbstbevorzugung, Monopolisierung und Raising Rivals Costs mit sich bringen und (iii) bisher funktionierende Abhilfemaßnahmen unter den Rahmenbedingungen digitalisierter Medien- und Unterhaltungsmärkte wohlfahrtssenkende Wirkungen entfalten können. Daher bedarf es einer Modernisierung der Wettbewerbsordnung für die Unterhaltungsindustrien.

Understanding cross border innovation activities: the linkages between innovation modes, product architecture and firm boundaries. - In: Journal of business research, ISSN 0148-2963, Bd. 128 (2021), S. 762-769
The mirroring hypothesis highlights the correspondence of design characteristics across different architectural levels and in this paper, we consider how mirroring may impact the distribution of national and international innovation activities of firms. We identify incremental and modular innovations (as product architecture reinforcing innovations) along with architectural and radical innovations (as innovations that overturn the existing product architecture) to consider how and when innovation activities may adopt an international dimension. Our study of the bicycle industry highlights that international collaboration is most likely to occur in respect of incremental and modular innovation on the basis of the embedded coordination that modular designs offer. However, even in these circumstances, international collaboration was limited, on the basis that cross-national collaboration created higher levels of complexity and uncertainty; thereby being an attractive option only when the capabilities of the international partner far exceeded what was available either internally, or within national boundaries.

Stars in social media : new light through old windows?. - In: Journal of media business studies, ISSN 2376-2977, Bd. 18 (2021), 2, S. 79-105
We review the economics of superstars, originally developed for stars in traditional media, and discuss whether they are applicable for the novel phenomenon of stars in social media (influencer, micro-celebrities). Moreover, we analyse potentially new factors for creating social media superstardom. Our overall result is that the economics of superstars remain applicable and relevant for social media stars. In line with this assessment, we find that several (allegedly) new star factors in social media, like disappearance of gatekeepers and authenticity, turn out to be just slightly different to traditional concepts. However, algorithm management and upload strategies represent novel success factors relevant for social media superstardom that are not captured by traditional superstar theories.
