The economics of the German investigation of Facebook's data collection. - Ilmenau : Ilmenau University of Technology, Institute of Economics, 2020. - 1 Online-Ressource (43 Seiten). . - (Ilmenau economics discussion papers. - vol. 26, no. 139)

The importance of digital platforms and related data-driven business models is ever increasing and poses challenges for the workability of competition in the respective markets (tendencies towards dominant platforms, paying-with-data instead of traditional money, privacy concerns, etc.). Due to such challenges, investigations of such markets are of high interest. One of recent cases is the investigation of Facebook's data collection practices by German competition authorities. Our paper, in contrast to the wide stream of legal studies on this case, aims to analyze whether Facebook's practices regarding data collection could constitute an abuse of market power from an economic perspective, more specifically against the background of modern data economics. In doing so we summarize the state of the advanced theories, including influences from behavioral economics, addressing such markets, and discuss four potential theories of harm.

Evolutionary bilevel approach for integrated long-term staffing and scheduling. - Ilmenau : Technische Universität Ilmenau, Fakultät für Wirtschaftswissenschaften und Medien, Institut für Wirtschaftsinformatik. - 1 Online-Ressource (ii, 13 Seiten). . - (Ilmenauer Beiträge zur Wirtschaftsinformatik. - 2020,2) ISBN 978-3-938940-63-1

Determining size and structure of a companys workforce is one of the most challenging tasks in human resource planning, especially when considering a long-term planning horizon with varying demand. In this paper an approach for integrated staffing and scheduling in a strategic long-term context is presented by applying evolutionary bilevel optimization. For demonstration, the example of determining the number of employees in different categories over the period of one year in a midsized call center of a utility is used. In doing so, two contrary objectives were optimized simultaneously: reduce the overall workforce costs and retain a high scheduling quality. The results show that the proposed approach could be used to support corporate decision making related to strategic workforce planning, not only for call centers but for any other kind of workforce planning involving personnel scheduling.

Holistic workforce planning: integrating staffing, shift design and scheduling using evolutionary bilevel optimization. - Ilmenau : Technische Universität Ilmenau, Fakultät für Wirtschaftswissenschaften und Medien, Institut für Wirtschaftsinformatik. - 1 Online-Ressource (ii, 16 Seiten). . - (Ilmenauer Beiträge zur Wirtschaftsinformatik. - 2020,1) ISBN 978-3-938940-62-4

Personnel scheduling is an important and challenging task that arises in a variety of application areas. Scheduling quality, however, strongly depends on the results of the preceding activities of staffing and shift design. This paper presents a novel approach that integrates staffing, shift design and scheduling into one optimization problem for the first time, providing a holistic view of the workforce planning process. By applying an evolutionary multi-objective bilevel algorithm, the three objectives staffing costs, number of shifts and scheduling quality are optimized simultaneously. The experimental results show that the presented holistic approach is suitable to support decision making regarding staffing as well as shift design by showing the decision maker tradeoffs between different solution alternatives. Furthermore, applying the holistic approach reveals new promising solution areas and valuable individual solutions, which would not have been found when optimizing sequentially.

What drives binge-watching? : an economic theory and analysis of impact factors. - Ilmenau : Ilmenau University of Technology, Institute of Economics, 2020. - 1 Online-Ressource (29 Seiten). . - (Ilmenau economics discussion papers. - vol. 26, no. 138)

Behavioral patterns in media consumption are changing. With the upcoming of video-on-demand platforms, so-called "binge-watching" gained broad awareness. To the best of our knowledge, this is the first economic analysis explicitly on binge-watching. We approach the phenomenon by arguing that it follows fundamental patterns of addictive behavior. By applying concepts of rational addiction and behavioral economics, we derive (i) a theoretical understanding of binging-watching behavior and (ii) factors increasing the likelihood of binging, especially with modern technologies and digital media services. The decision to binge depends on individual factors such as the accumulation rate of consumption capital (speed of learning and acquiring knowledge), opportunity costs, and the expected value of consumption. Consumption capital in the form of specific knowledge positively influences marginal utility. Moreover, binge-watching is not specific to online streaming services (video-on-demand), but modern platforms facilitate certain factors which increase the consumers' engagement. Non-linear, self-organized video scheduling and a single narrative (coherent plot) increase the likelihood for consumers to binge.

The battle of YouTube, TV and Netflix - an empirical analysis of competition in audio-visual media markets. - Ilmenau : Ilmenau University of Technology, Institute of Economics, 2020. - 1 Online-Ressource (39 Seiten). . - (Ilmenau economics discussion papers. - vol. 26, no. 137)

The world of audiovisual online markets is rapidly changing. Not long ago, it was dominated by linear television, transmitted terrestrially, through cable networks or via satel-lite. Recently, streaming services like Netflix, YouTube, Amazon Prime and others have emerged as new suppliers of audiovisual content. In this quickly changing industry, compe-tition interrelations between such different formats like traditional TV, videos on YouTube, and streaming via Netflix are subject to controversy. In particular, doubt is cast on services like YouTube exerting competitive pressure on services like Netflix and traditional TV. Based upon a survey with almost 3,000 participants, we provide an empirical analysis of consump-tion behavior of audiovisual contents. Using descriptive and analytical statistics, including multiple equation models, we show that there are specific areas within audiovisual content markets where YouTube exerts considerable competitive pressure on both Netflix and classic TV, for instance, through prime time video entertainment. However, our analysis yields dif-ferentiated results as we also identify areas where competition intensity between different service types appear to be low, for instance, through daytime and regarding the intention to shorten waiting time.
