TY - JOUR A1 - Rötzel, Peter T1 - Information overload in the information age: a review of the literature from business administration, business psychology, and related disciplines with a bibliometric approach and framework development JF - Business Research N2 - In the light of the information age, information overload research in new areas (e.g., social media, virtual collaboration) rises rapidly in many fields of research in business administration with a variety of methods and subjects. 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.

Generally, both the party that initiates such renegotiations and the time at which renegotiations are launched determine the outcome of the PPP’s renegotiated remuneration. This effect is moderated by the degree of contract specificity and by a decrease in demand. Specifically, when the public client initiates the renegotiation of an incomplete contractual agreement due to a decrease in demand, it can successfully reduce the remuneration of the PPP.

We conducted two experiments with Chinese participants and used a replication of Staw's (1976) often cited case.

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.

Der Umgang mit Risiken ist geprägt durch mögliche kognitive Verzerrungen und subjektive Bewertungen der beteiligten Personen.So zeigen empirische Studien aus der betriebswirtschaftlichen und psychologischen Forschung bei der Risikowahrnehmung einige Verhaltensmuster von Entscheidungsträgern auf, die sich durch Heuristiken (sog. „Daumenregeln“) erklären lassen.Der Einsatz dieser Heuristiken ist evolutionär bedingt und ermöglicht es Menschen, durch einen sparsamen Umgang mit begrenzten kognitiven Ressourcen in kurzer Zeit zu einer Bewertung zu kommen (vgl.Renn et al., 2007). Der Einsatz von Heuristiken führt allerdings häufig dazu, dass die von Entscheidungsträgern geschätzte Eintrittswahrscheinlichkeit von Risiken sehr stark von der objektiven statistischen Eintrittswahrscheinlichkeit abweicht (vgl. Hertwig/Wulff,2014).

The study uses survey data and a database from a large company that is one of Europe’s top performers in idea management. In addition to the idea database, this study surveys participating employees about their perceptions of fairness and their participation behavior and knowledge sharing behavior. 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. To increase the value of innovation ideas, social networks for innovation ideas can be used if the allocation of rewards for idea providers is positively associated with the fairness perceptions of network members.

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.

Neben den vielen Vorteilen der Weiterentwicklung von Managementinformationssystemen und der stetig höheren Verfügbarkeit von Informationen ist allerdings auch die Entwicklung zu betrachten, dass immer mehr Entscheidungsträger zu viele Informationen erhalten (vgl. Lohr, 2007). Quellen dieser Informationsüberlast sind das interne Berichtswesen und die schnelle und aufwandsarme Verfügbarkeit von Informationen über Managementinformationssysteme. Darüber hinaus ist die Herausforderung, auch für das Controlling, Entscheidungsträgern im Unternehmen einen optimalen Umfang an Informationen zur Verfügung zu stellen, keine reine IT-Problematik, sondern betrifft sehr stark auch die Bereiche Personalwesen und Organisation. Daher sollte das Controlling in seiner Koordinationsfunktion auch Personalwesen und Organisation berücksichtigen.

Allerdings führen das stetige Wachstum des internationalen Handels und die steigende globale Abhängigkeit von Produktionsprozessen zu einem hohen Anpassungsdruck auf die Managementinformationssysteme, die zumeist mit hohen Kosten verbunden sind. Die Anpassung oder Neuausrichtung des Managementinformationssystems kann allerdings auch große Chancen beinhalten: Unternehmen, welche starkes Augenmerk auf Managementinformationssysteme legen und deutlich mehr in diesen Bereich investieren als die Peergroup, erzielen starke Prozessverbesserungen in der Wertschöpfungskette und erreichen damit eine signifikante Ersparnis bei den Betriebskosten, die bei den Best-in-class Unternehmen bei einem Mehrfachen der investierten Mittel liegen kann.
