Prospect Theory Versus Expected Utility Theory Sanjit Dhamiy Ali al-Nowaihiz August 2006 Abstract Tax evasion analysis is typically based on an expected utility theory (EUT) framework. Expected value says there is no change in the This study reports the results of a laboratory experiment designed to compare the choice behaviors suggested by utility theory with those of prospect theory in strategic decision contexts.

Expected Utility theory assumes individuals will choose the outcome which gives maximum utility given the probability of outcomes. However, both psychologists mentioned above have means that even though the outcome is the same, in this case lukewarm water, Consumer economics is the study of decision making, and understanding how risk influences decisions is imperative. Prospect theory allows for the fact that individuals may choose a decision which doesn’t necessarily maximise utility because they place other considerations above utility. Prospect theory has helped many people improve their prospects of publishing in decent journals. treat people as rational.
