Abstract
In this paper, we show an analysis on a Misrepresentation Game with ambiguous preferences. A Misrepresentation Game is a game that sometimes an agent obtains higher utility than truth-telling on a preference-elicitation based fair division negotiation by misrepresenting their preferences while it is still difficult to be noticed by the counterpart. We investigate whether we can generate mechanisms for fair negotiations which avoids incentives to make misrepresentations by using a way of automated design of mechanisms.
