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...

This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards...

It has been widely documented in laboratory experiments that subjects act more risk-averse when they make their decisions frequently (e.g., one as opposed to several decisions at a time), a phenomenon dubbed "myopic loss aversion" by Benartzi and Thaler (1995). The present paper uses two new...
