Thus the gain-loss value of 'not purchasing insurance' is negatively associated with loss aversion. In other words, the value people place on avoiding a certain loss is higher than the value of acquiring a gain of equal size.

They show that, should a shock occur, loss aversion would reduce the chance of renegoti- Prospect theory introduces several anomalies in the behavior of rational agents, including loss aversion, the reflection effect, probability weighting, and the certainty effect.
