A choice problem is risky (respectively ambiguous) if the decision maker is choosing between probability distributions (respectively sets of probability distributions) over utility relevant consequences. We provide an axiomatic foundation for and a representation of continuous linear preferences...

From Breiman et al. [...] are singleton sets, this is the Blackwell and Dubins [2] version of Skorohod's representation theorem.

This paper considers dynamic moral hazard settings, in which the consequences of the agent's actions is not precisely understood. In a new continuous-time principal-agent model with drift ambiguity, the agent's unobservable action translates to drift set for the diffusion processes that describe...
