Abstract

We propose a new theory of choice between lotteries, which combines an 'economic’ view of decision making - based on a rational, though incomplete, ordering - with a 'psychological’ view - based on heuristics. This theory can explain observed violations of EU theory, namely all cyclical patterns of choice as well as violations of independence.
