The value function is steeper for losses than for gains, with a loss aversion coefficient of approximately 2.25.

Many canonical demonstrations of loss aversion can be explained by other mechanisms. The evidence for a general loss aversion coefficient is weaker than commonly believed.
Brown, Imai, Vieider & Camerer, 'Meta-analysis of Empirical Estimates of Loss Aversion,' Journal of Risk and Uncertainty (2024)FLAGGED: DOI not in registry
Across 607 estimates from 150 articles, the median loss aversion coefficient is 1.69, confirming losses loom larger than gains but less than the original 2.25 estimate.
