Notice that this is an ex ante definition. We would hardly ual to gather evidence if he or she didn t expect to learn enough so as to possibly affect a decision. Bayes theorem is simply a device to proci learned. The crucial requirement for evidence to constitute information is that for at least some evidence that might be received beliefs will be sufficiently affected that the optimal decision will change. Also the definition is individual-specific. As pointed out viduals may differ in their reaction to the same information source. For example their prior probabilities may differ so that posterior probabilities and hence their decisions may differ even when confronted with the same evidence. The definition should really be interpreted net of cost. Ail information source may have the potential to affect an individuals decision but if it is too costly it is not information because it will not be used. It can be argued however that financial statements are a cost-effective information source because of the large number of potential users. Finally it should be emphasized that an individual s receipt of information
