We investigate the computational complexity of several decision problems in hedonic coalition formation games and … is NP-hard in the strong sense. Furthermore, the corresponding decision problems with respect to the existence of a Nash …

Contemporary approaches to decision making describe a decision problem by sets of states and outcomes, and a rich set … of acts: functions from states to outcomes over which the decision maker (DM) has preferences. Real problems do not come … decision making, in which the primitive objects of choice are syntactic programs. We show that if the DM's preference relation …

which the decision maker has to make some effort in order to avoid mistakes when implementing any desired outcome. The … disutility of this effort enters the decision maker's goal function in an additively separable way. A particular disutility …

This paper analyses whether freedom of decision as a crucial precondition of normative deci-sion theory is questioned … decision as the necessary basis for handling ethical questions in business practice, rather then as a limitation to this end … plain determination on the one extreme and complete autonomy on the other. It supports the proposition in decision theory …
