This paper experimentally investigates individual information acquisition and decisions in ambiguous situations in which the degree of ambiguity can endogenously and individually be decreased by the subjects. In particular, I analyze how risk aversion, ambiguity attitude and personality traits are related to an individual’s information acquisition prior to a decision and to the decision itself based on this information. I focus on urn decisions and conduct treatments that consider the loss and gain domain separately and that vary the amount of available information and the probabilistic structure.
