We investigate various statistical methods for forecasting risky choices and identify important decision predictors. Subjects (n=44) are presented a series of 50/50 gambles that each involves a potential gain and a potential loss, and subjects can choose to either accept or reject a displayed...

There is a long ongoing debate on whether interaction in a market influences moral decisions of individuals. While some studies show that individuals tend to decide less morally when being exposed to a market environment, other studies argue that the experience of market interaction promotes...

A key premise underlying most of the economic literature is that rational decision-makers will choose dominant strategies over dominated alternatives. However, prior literature in various disciplines including business, psychology, and economics document a series of phenomena associated with...

The increasing digitalization in the process and the end-result of public service, a phenomenon widely known as e-government, is changing the range and ways of collaboration among governments and their stakeholders. Especially with the pervasive use of social media for knowledge sharing,...

In this study we introduce a new stochastic choice rule that categorizes objects in order to simplify the choice procedure. At any given trial, the decision maker deliberately randomizes over mental categories and chooses the best item according to her utility function within the realized...

Unternehmen stehen aktuell aufgrund der Digitalisierung, des stetigen technologischen Fortschritts und immer kürzer werdenden Produktlebenszyklen vor großen Herausforderungen. Das Ziel der Arbeit ist die Unterstützung von Stakeholdern bei der Entscheidungsfindung im...

Diese Untersuchung beschäftigt sich mit der konsistenten und effizienten Ausgestaltung eines Risikomanagementsystems, das geeignet ist die Auswirkungen der Ungewissheit in betriebswirtschaftlichen Entscheidungssituationen besser zu verstehen und Strategien für eine aktive Steuerung von...

Kernelement der neuen Finanzwissenschaft ist die entscheidungstheoretische Fundierung von Verhaltensfunktionen. Gerade gegen diese Fundierung auf der Basis individueller Optimierungskalküle richtet sich allerdings schon immer der Vorwurf der Realitätsferne. Diese Arbeit untersucht, ob man die...

In this paper, we propose an interpretation of the Hilbert space method used in quantum theory in the context of decision making under uncertainty. For a clear comparison we will stay as close as possible to the framework of SEU suggested by Savage (1954). We will use the Ellsberg (1961) paradox...

I provide axiomatic foundations for a model of taste uncertainty with endogenous learning through consumption. In this setting, uncertainty is over an unobservable, subjective state space. Preference over lottery-menu pairs is sufficient to identify the state space and the learning process. In...

This paper studies associations between the use of formal decision-making processes in e-Government projects and the outcomes of these projects. By doing so, this study contributes to the decision sciences as well as to the fields of e-Government, information systems and public administration....

Consideration set models relax the assumption that consumers are aware of all available options. Thus far, identification arguments for these models have relied either on auxiliary data on what options were considered or on instruments excluded from consideration or utility. In a discrete choice...

Equality of opportunity is usually defined as a situation where the effect of circumstances on outcome is nullified (compensation principle) and effort is rewarded (reward principle). We propose a new version of the reward principle based on the idea that effort deserves reward for it is costly....
