We show that the no betting characterisation of the existence of common priors over finite type spaces extends only partially to improper priors in the countably infinite state space context: the existence of a common prior implies the absence of a bounded agreeable bet, and the absence of a common improper prior implies the existence of a bounded agreeable bet. However, a type space that lacks...

Countable spaces and common priors

We show that the no betting characterisation of the existence of common priors over finite type spaces extends only partially to improper priors in the countably infinite state space context: the existence of a common prior implies the absence of a bounded agreeable bet, and the absence of a common improper prior implies the existence of a bounded agreeable bet. However, a type space that lacks...

Iterated Expectations with Common Beliefs

This paper generalizes a result by Samet concerning iterated expectations and common priors. When a player in some state of the world is allowed to ascribe probability zero to that state, something not allowed in Samet’s framework, iterated expectations may not converge, and when they do, common knowledge of their limit may not characterize a common prior. It is shown here that replacing common...

Iterated Expectations and Common Priors

A necessary and sufficient condition for the existence of a common prior for several players is given in terms of the players’ present beliefs only. A common prior exists iff for each random variable it is common knowledge that all its iterated expectations converge to the same value; this value is its expectation with respect to the common prior. The proof is based on the presentation of type ...

Exchanging Iterated Expectations of Random Upper Semicontinuous Functions: an application to decision theory

In this paper we present a procedure to deal with a kind of single-stage decision problems with imprecise utilities. In this type of problems the product measurability of the utility function is not required. So that, the involved expectations are calculated by means of iterated integrals instead of integrals over product spaces. Keywords— Bayesian decision analysis, Iterated expectation, Kudo-...
