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.

A multiple-prior decision maker is open-minded if she can describe, as subjective uncertainty, all convex sets of distributions over payoff relevant consequences. Theorem 1: open-mindedness is equivalent to the ability to subjectively describe both the uniform distribution on an interval and the...

We propose a model of political persuasion in which a biased newspaper aims to convince voters to vote for the government. Each voter receives the newspaper's report, as well as an independent private signal. Voters then exchange this information on social media and form posterior beliefs,...

This paper studies health insurance over the life-cycle with adverse selection to analyze the welfare implications of the Aordable Care Act of 2010 that targets at improving the access to health insurance for the uninsured. For this purpose, this study develops a life-cycle model following...
