To see how prospect theory can be applied, consider the decision to buy insurance. Assume the probability of the insured risk is 1%, the potential loss is $1,000 and the premium is $15. If we apply prospect theory, we first need to set a reference point. This could be the current wealth or the worst case (losing $1,000).
The new theory eliminated the editing phase in prospect theory and focused just on the evaluation phase. Its main feature was that it allowed for non-linear probability weighting in a cumulative manner, which was originally suggested in John Quiggin 's rank-dependent utility theory.
In 1979, Daniel Kahneman and Amos Tversky traced the cause of the disposition effect to the so-called "prospect theory". [3] The prospect theory proposes that when an individual is presented with two equal choices, one having possible gains and the other with possible losses, the individual is more likely to opt for the former choice even ...
Reference dependence is a central principle in prospect theory and behavioral economics generally. It holds that people evaluate outcomes and express preferences relative to an existing reference point, or status quo. It is related to loss aversion and the endowment effect. [1] [2]

Prospect theory involves the idea that when faced with a decision-making event, an individual is more likely to take on a risk when evaluating potential losses, and are more likely to avoid risks when evaluating potential gains. This can influence one's decision-making depending if the situation entails a threat, or opportunity.
The political opportunity theory has much in common with the related resource mobilization theory, particularly when it is seen as focusing on mobilization of resources external to the movement. [3] Associated and indigenous organizations also play a major role in recruiting and motivating actors to join and participate within social movements.
Prospect theory posits that a loss is more significant than the equivalent gain, [2] that a sure gain (certainty effect and pseudocertainty effect) is favored over a probabilistic gain, [3] and that a probabilistic loss is preferred to a definite loss. [2]
