The past advancements in Reinforcement Learning (RL) provided more capable algorithms that can be used to solve pricing problems. In this paper, we study the performance of Deep Q-Networks (DQN) and Soft Actor Critic (SAC) in different market models. We consider tractable duopoly settings, where optimal solutions derived by dynamic programming techniques can be used for verification, as well as oligopoly settings, which are usually intractable due to the curse of dimensionality. We find that both algorithms provide reasonable results, while SAC performs better than DQN. Moreover, we show that under certain conditions, RL algorithms can be forced into collusion by their competitors without direct communication.}, language = {en} } @article{SchweringSommerUeppingetal.2022, author = {Schwering, Anja and Sommer, Friedrich and Uepping, Florian and Winkelmann, Sandra}, title = {The social-psychological perspective on executive compensation}, series = {Journal of Business Economics}, volume = {92}, journal = {Journal of Business Economics}, number = {2}, publisher = {Springer}, address = {Berlin}, doi = {10.1007/s11573-021-01066-5}, pages = {309 -- 345}, year = {2022}, abstract = {This paper investigates whether and how social-psychological mechanisms, namely reciprocity, demographic similarity, and similar experiences, affect CEO compensation packages with respect to the levels of total, fixed, and short- and mid-term compensation and the variable proportion of the compensation package. We use evidence from Germany as it is considered a prototype of a two-tier board system. Given the primary roles of both the CEO and the chair of the supervisory board, we especially highlight social-psychological mechanisms in the process leading to the final compensation package. Using a hand-collected sample of non-financial constituents of the German HDAX, we find that reciprocity can lead to a compensation package that is more favorable for the CEO. Results on similarity are ambivalent such that the effects of similarity on CEO compensation—both positive and negative—may depend on the dimension of similarity. Finally, the chair's CEO experience, both inside and outside the focal company, also plays an essential role in shaping CEO compensation. More specifically, CEO experience in general is associated with more favorable compensation. However, having a chair that has been CEO at the focal company correlates with less favorable compensation packages except for when the CEO has also been recruited internally.}, language = {en} } @article{Surrey2022, author = {Surrey, Heike}, title = {Neuroleadership}, publisher = {Sch{\"a}ffer-Poeschel}, address = {Stuttgart}, isbn = {978-3-7910-5642-5}, pages = {247}, year = {2022}, abstract = {Wie k{\"o}nnen notwendige Systemwechsel „gemanaged" werden, wenn die etablierten F{\"u}hrungsans{\"a}tze an heutigen Entwicklungen vorbeigehen?

Nevertheless, it is a prerequisite for the functioning of the European Union that all member states and their subnational authorities apply and enforce EU legislation in due time. I address this research gap and take a closer look at the legal transposition process in the German regional states. Using a novel data set comprising detailed information on about 700 subnational measures, I show that state-level variables, such as political preferences and ministerial resources, account for variation in the timing of legal transposition and repeatedly lead to subnational delay. To conclude, the paper addresses the role of subnational authorities in the EU multi-level system and points to their interest in shaping legal transposition in order to counterbalance their loss of competences to the national level.}, language = {en} } @article{HuettelBalderjahn2022, author = {H{\"u}ttel, Alexandra and Balderjahn, Ingo}, title = {The coronavirus pandemic}, series = {The Journal of consumer affairs}, volume = {56}, journal = {The Journal of consumer affairs}, number = {1}, publisher = {Wiley}, address = {Hoboken}, issn = {1745-6606}, doi = {10.1111/joca.12419}, pages = {68 -- 96}, year = {2022}, abstract = {As a means to preserve present and future generations' living conditions, sustainable consumption presents a route to the enhanced well-being of individuals. However, the occurrence of the COVID-19 pandemic raises the question of whether society is going to continue down a path of increased awareness of sustainable consumption or whether the pandemic will move people to focus more on themselves. Based on data gathered before and near the end of the first pandemic lockdown in Germany in spring 2020, this research demonstrates that ecological, social, and voluntary simplicity consciousness deteriorated in the minds of sustainability-conscious consumers, with notable impacts on their willingness to spend sustainably and their shopping affinity. Furthermore, we identify segments that show particular vulnerability to the lockdown by reacting with a decrease in their ecological consumption consciousness. This study concludes with a discussion of the pandemic's implications for the spread of sustainable consumption styles and human well-being.}, language = {en} } @article{GleissLewandowski2022, author = {Gleiß, Alexander and Lewandowski, Stefanie}, title = {Removing barriers for digital health through organizing ambidexterity in hospitals}, series = {Journal of public health}, volume = {30}, journal = {Journal of public health}, number = {1}, publisher = {Springer}, address = {Heidelberg}, issn = {2198-1833}, doi = {10.1007/s10389-021-01532-y}, pages = {21 -- 35}, year = {2022}, abstract = {Aim Hospitals noticeably struggle with maintaining hundreds of IT systems and applications in compliance with the latest IT standards and regulations. Thus, hospitals search for efficient opportunities to discover and integrate useful digital health innovations into their existing IT landscapes. In addition, although a multitude of digital innovations from digital health startups enter the market, numerous barriers impede their successful implementation and adoption. Against this background, the aim of this study was to explore typical digital innovation barriers in hospitals, and to assess how a hospital data management platform (HDMP) architecture might help hospitals to extract such innovative capabilities. Subject and methods Based on the concept of organizational ambidexterity (OA), we pursued a qualitative mixed-methods approach. First, we explored and consolidated innovation barriers through a systematic literature review, interviews with 20 startup representatives, and a focus group interview with a hospital IT team and the CEO of an HDMP provider. Finally, we conducted a case-study analysis of 36 digital health startups to explore and conceptualize the potential impact of DI and apply the morphological method to synthesize our findings from a multi-level perspective. Results We first provide a systematic and conceptual overview of typical barriers for digital innovation in hospitals. Hereupon, we explain how an HDMP might enable hospitals to mitigate such barriers and extract value from digital innovations at both individual and organizational level. Conclusion Our results imply that an HDMP can help hospitals to approach organizational ambidexterity through integrating and maintaining hundreds of systems and applications, which allows for a structured and controlled integration of external digital innovations.}, language = {en} } @book{Richter2022, author = {Richter, Martin}, title = {Das Beteiligungsmanagement als Intermedi{\"a}r}, series = {Beh{\"o}rden Spiegel.

To do so, we surveyed 350 students and analyzed the impact of the different dispositions using ordinary least squares regression analysis.

Moreover, their potential to coordinate partially autonomous entities as typical for federal organized states is highlighted. This study contributes through a uniform understanding of public service platforms by providing a framework with constitutive elements, that may guide future analysis. Apart from chance regarding coordination, platforms are well suited to support contextual eGovernment targets. Among them is service personalization. Highly individualized service offerings support targets such as No Stop government.
