The FASB and the IASB have defined the provision of decision useful information as the primary objective of financial reporting. Decision usefulness is based on two fundamental qualitative characteristics, relevance and reliability (now replaced by “faithful representation”). Using a...

Investor judgment and decision-making (JDM) is influenced by several factors. We examine the effect of dispositional goal orientation (approach and avoidance motivation), as well as situational goal orientation (gain- and loss-framing), on non-professional investors' JDM. In an experiment, 150...

We contribute to the field of Ramsey-type equilibrium models with heterogeneous agents. To this end, we state such a model in a time-continuous and time-discrete form, which in the latter case leads to a finite-dimensional mixed complementarity problem. We prove the existence of solutions of the...

While single-level Nash equilibrium problems are quite well understood nowadays, less is known about multi-leader multi-follower games. However, these have important applications, e.g., in the analysis of electricity and gas markets, where often a limited number of firms interacts on various...

This paper mainly studies two topics: linear complementarity problems for modeling electricity market equilibria and optimization under uncertainty. We consider both perfectly competitive and Nash-Cournot models of electricity markets and study their robustifications using strict robustness and...

Die deutsche Infrastrukturdebatte ist durch ökonomische Perspektiven geprägt und vernachlässigt häufig die Besonderheiten der beiden Teilbereiche sozialer und technischer Infrastrukturen und die Abstimmungsprobleme sowohl zwischen den verschiedenen Sparten der Infrastrukturplanung als auch...
