This review article analyzes the development of information overload literature in business administration and related interdisciplinary fields and provides a comprehensive and overarching overview using a bibliometric literature analysis combined with a snowball sampling approach. For the last decade, this article reveals research directions and bridges of literature in a wide range of fields of business administration (e.g., accounting, finance, health management, human resources, innovation management, international management, information systems, marketing, manufacturing, or organizational science). This review article identifies the major papers of various research streams to capture the pulse of the information overload-related research and suggest new questions that could be addressed in the future and identifies concrete open gaps for further research. Furthermore, this article presents a new framework for structuring information overload issues which extends our understanding of influence factors and effects of information overload in the decision-making process.}, subject = {Informations{\"u}berlastung}, language = {en} } @article{LohmannRoetzel2017, author = {Lohmann, Christian and R{\"o}tzel, Peter}, title = {The Outcome of Renegotiations between Institutionalized Public-Private Partnerships and Their Public Clients}, series = {International Journal of Public Administration}, volume = {41}, journal = {International Journal of Public Administration}, number = {9}, doi = {https://doi.org/10.1080/01900692.2017.1298128}, pages = {735 -- 745}, year = {2017}, abstract = {This study analyzes the renegotiations that take place between institutionalized public-private partnerships (PPPs) and their public clients drawing on survey data on the PPPs of the German Federal Armed Forces.

This effect is moderated by the degree of contract specificity and by a decrease in demand.

Whereas previous studies focus on the complexity of information, this study investigates how different quantities of information influence escalation of commitment and how information load interacts with a decision maker's interpretation of negative feedback regarding earlier decisions. In situations in which escalation of commitment can occur, infor-mation load is relevant for decision making for two reasons. First, in escalation situations in which decision makers face negative feedback, information load exacerbates the tendency to escalate commitment. Second, when an escalation tendency is absent, information load can lead to a decision to continue a losing course of action, which can be mistaken for escalation of commitment. Furthermore, decision makers with a higher level of creativity tend to invest more than decision makers with a lower level of creativity. Surprisingly, creative decision makers do not change their behavior when facing negative consequences while less creative decision mak-ers show an escalation of commitment tendency.}, subject = {Informationsverhalten}, language = {en} } @article{Roetzel2015, author = {R{\"o}tzel, Peter}, title = {Kognitive Verzerrungen bei der Wahrnehmung von Risiken}, series = {Controlling}, volume = {27}, journal = {Controlling}, number = {6}, doi = {https://doi.org/10.15358/0935-0381-2015-6-320}, pages = {320 -- 322}, year = {2015}, abstract = {Die Analyse, Bewertung, Kommunikation und Steuerung von Risiken wird oftmals durch das Controlling unterst{\"u}tzt oder selbst durchgef{\"u}hrt.

The results show that there is a clear relationship between innovation idea value, employees' perceptions of fairness, and employees' participation behavior and knowledge sharing behavior. Furthermore, there is clear evidence that tenure increases the value of innovation ideas. The findings suggest a number of implications for ideation management and for the design of social networks for innovation ideas.

The analyzed PPPs are unique in that the German Federal Ministry of Defence, a government institution, has a dual role as a main shareholder and a major customer. Drawing on these data, the present article analyzes how a government institution influences a PPP's set of objectives and shows that the conflict of interest with respect to monetary objectives between the government institution and the PPP as a whole is low in such partnerships. Furthermore, the article examines the opportunistic behavior of PPPs in contractual renegotiations where the government institution acts as a customer. The results show that, although such behavior indeed occurs, it does not concern monetary issues, since the government institution can control the monetary objectives of PPPs in which it is a main shareholder. Third, this study also analyzes and identifies certain exogenous factors that may influence the level of opportunistic behavior exhibited by the examined PPPs, providing evidence on the causes and effects of such behavior and indicating how it can be limited by the government institution.}, subject = {Public Private Partnership}, language = {en} } @article{Roetzel2014, author = {R{\"o}tzel, Peter}, title = {Informationslast im unternehmensinternen Berichtswesen}, series = {Controlling}, volume = {26}, journal = {Controlling}, number = {10}, doi = {https://doi.org/10.15358/0935-0381_2014_10_566}, pages = {566 -- 567}, year = {2014}, abstract = {Informationslast ist in der heutigen „Information Society" ein wesentlicher Faktor bei Entscheidungen im Unternehmensalltag.
