The α-MEU model and the smooth ambiguity model are two popular models in decision making under ambiguity. However, the …

First, we define two notions of more ambiguous with respect to such a class. A more ambiguous (I) act … makes an ambiguity averse decision maker (DM) worse off but does not affect the welfare of an ambiguity neutral DM. A more …

Regarding symmetry assumptions, we show that, under relatively mild conditions, a variety of preference … stringent.
