A meta-analysis of price change fairness perceptions

The dual entitlement principle suggests that price change motives influence price fairness perceptions. A meta-analysis replicates this finding, and shows that the negative effect of unjustified motives is stronger than the positive effect of cost-justified motives; motive effects are independent of the magnitude of the price change; and price fairness is explained better by price changes than by motives. The relationship between price change and price fairness follows a cubic function, indicating satiation effects for high price changes.
