Subjective expected utility is currently the dominant model for preferences of an agent that chooses between acts. In this
thesis we look at some of the critiques of the model, with special focus on the Ellsberg paradox. We then take a look at the expected utility in the uncertainty model proposed by Gul Faruk and Wolfram Pesendorfer, our main question being how the proposed model interacts with edge cases defined in the critiques of Subjective expected utility. We conclude that expected utility in uncertainty is capable of modeling the Ellsberg paradox in its entirety and we present an example.
