Implicit vs. Explicit Deception in Ultimatum Games with Incomplete Information

We explore bargaining, using ultimatum games, when one party, the proposer, possesses private information about the pie size and can either misrepresent this information through untruthful statements (explicit deception) or through information-revealing actions (implicit deception). Our study is the first such direct comparison between two ways in which people can deceive. We find that requirin...

Games with Incomplete Information

1. Game theory and classical economics. Game theory is a theory of strategic interaction. That is to say, it is a theory of rational behavior in social situations in which each player has to choose his moves on the basis of what he thinks the other players’ countermoves are likely to be. After preliminary work by a number of other distinguished mathematicians and economists, game theory as a sy...

Bayesian Games: Games with Incomplete Information

Glossary Bayesian game An interactive decision situation involving several decision makers (players) in which each player has beliefs about (i. e. assigns probability distribution to) the payoff relevant parameters and the beliefs of the other players. State of nature Payoff relevant data of the game such as payoff functions, value of a random variable, etc. It is convenient to think of a state...

Information in Ultimatum Games: An Experimental Study

This study reports on an experiment using variations of the ultimatum game. The experiment controls the amount and type of information known to the responder in the game. In two treatments, she knows both the absolute (money) and relative (fairness) payoffs from an offer. In the other two, she knows either only the absolute or only the relative payoffs. The predictions of four models for these ...
