Uncertainty, Ambiguity and Risk Taking : An Experimental Investigation of Consumer Behavior and Demand for Insurance

The purpose of this paper is to examine whether people treat all forms of uncertainty in the same way. Studies investigating known-risk gambles and ambiguous gambles have systematically used the urn context. Little systematic research has investigated differences in expressed attitude as a function of the manner in which vague probability information is communicated to a decision maker. The experiments reported in this paper examine the behavior of people when faced with a different situations with and without an insurance context: a risky situation (the probability of loss is known), an uncertain situation (there is no prior information on the probability of loss) or an ambiguous (the information provided is vague)
