摘 要:
Problem Definition: The loyalty penalty refers to a pricing strategy where companies charge higher prices to loyal customers for exploitation while offering lower prices to non-loyal customers for attraction. To address this unfair business practice, various regulatory agencies, such as the CMA and FCA in the UK, have proposed or implemented regulations aimed at promoting fairness in pricing. In this study, we analyze the impact of such regulations on both firms and consumers. Methodology and Results: We develop a stylized model to investigate duopoly competition in two symmetric markets, where consumers exhibit loyalty to different firms in each market. The regulatory intervention mandates that the price difference between the two markets, set by each firm, must not exceed a certain threshold. Our analysis reveals an intriguing interaction between market competition and price fairness regulation. When competition is intense, fairness regulation can alleviate cut-throat competition between firms, resulting in Pareto improvements compared to a scenario with no regulation. On the other hand, when competition is weak, fairness regulation can further enhance firms' existing monopoly power, potentially leading to collusive high prices that are detrimental to consumers and society. We also consider several extensions to enrich our findings, including fairness regulation on relative price discounts, asymmetric markets, and a two-pronged policy regulating the price gap and price cap. Managerial and Policy Implications: Our study reveals the economic consequences of price fairness regulations - firms can benefit by pricing fairly, but well-intended fairness requirements may have adverse effects on consumers.
