In the framework of Knightian uncertainty more precisely in the model introduced by Epstein and Schneider 3 different questions concerning the aspect of time-consistency, in the sense of m-stability or rectangularity, are studied.The first part describes an alternative description of...

Epstein and Schneider (2007) develop a framework of learning under ambiguity, generalizing maxmin preferences of Gilboa and Schmeidler (1989) to intertemporal settings. The specific belief dynamics in Epstein and Schneider (2007) rely on the rejection of initial priors that have become...

We show that the monotone continuity condition introduced by Arrow (1970) is the behavioral counterpart of countable additivity and weak compactness of the set of priors in a maxmin expected utility model. This generalizes Arrow's original result, who considered the special case of a singleton...
