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 …

-dimensional decision outcomes, economic theory assumes a uni-dimensional utility measure. This paper reviews evidence from behavioral and …Although decision makers are often reported to have difficulties in making comparisons between multi … brain sciences to assess whether, and for what reasons, this assumption may be warranted. It is claimed that the decision …

This allows the observer to make inferences about the latent subjective probability … consistently with expected utility theory or rank-dependent utility theory. Inferred subjective probabilities are significantly …

We provide characterizations of preferences representable by a Cobb-Douglas utility function. …

In most economics textbooks there is a gap between the non-existence of utility functions and the existence of … continuous utility functions, although upper semi-continuity is sufficient for many purposes. Starting from a simple constructive … the existence of upper semi-continuous utility functions on a wide class of domains. Although links between utility theory …

subjective probabilities. Cases 3 and 4 define the extent to which probabilities must be specified to solve a decision problem. …

Experimental research on decision making under risk has until now always employed choice data in order to evaluate the … empirical performance of expected utility and the alternative nonexpected utility theories. The present paper performs a similar …
