It is well known that, whereas in one-agent contexts the value of information is always positive, in strategic situations, this is not always the case. We will consider the class of games for which, under a specific information structure, there exists a unique Pareto payoff profile, and we show...

We exhibit a general class of interactive decision situations in which all the agents benefit from more information. This class includes as a special case the classical comparison of statistical experiments a la Blackwell.

We consider a stronger version of the paradox of multiple elections and show that it is possible that not only the winning combination of propositions, but also all the combinations sufficiently close to it, receive zero votes.
