In decision problems with absentmindedness the decision maker may manifest time-inconsistent choices in spite of unaltered preferences. In this paper we argue that this can be the case whenever the decision makeris reasoning is not appropriately modeled. More in particular, it is shown that the...

The paper presents a version of the EMAIL Game, originally proposed by Rubinstein (AER,1989), in which efficient coordination is shown to obtain even when the relevant coordination game is not mutual knowledge. In the model investigated a mediator is introduced in such a way that the two...

In the Email Game (Rubinstein, AER 89) noisy information channels may prevent efficient coordination, even when the game is almost common knowledge. In the paper we show that this is the case whenever message failure probabilities are not sufficiently different. Quite intuitively, the extent of...

An arms race for an artificial general intelligence (AGI) would be detrimental for and even pose an existential threat to humanity if it results in an unfriendly AGI. In this paper an all-pay contest model is developed to derive implications for public policy to avoid such an outcome. It is...
