Ellsberg Revisited: an Experimental Study

Yoram Halevy ()

Micro Theory Working Papers from Microeconomics.ca Website

Abstract: An extension to Ellsberg's experiment demonstrates that attitudes to ambiguity and compound objective lotteries are tightly associated. The sample is decomposed into three main groups: subjective expected utility subjects - who reduce compound objective lotteries and are ambiguity neutral, and two groups that exhibit different forms of association between preferences over compound lotteries and ambiguity - corresponding to alternative theoretical models that account for ambiguity averse or seeking behavior.
