Based on a mix of conceptual insights and findings from cases, this paper discusses three ways in which the effectiveness of regulation in the areas of competition, data and consumer protection can be improved by tailoring substantive protections and enforcement mechanisms to the extent of market power held by firms. First, it is analysed how market power can be integrated into the substantive scope of protection of data protection and consumer law, drawing inspiration from competition law’s special responsibility for dominant firms. Second, it is illustrated how more asymmetric and smarter enforcement of existing data protection rules against firms possessing market power can strengthen the protection of data subjects and stimulate competition based on lessons from priority-setting and cooperation by consumer authorities. Third, it is explored how competition law’s special responsibility for dominant firms can be further strengthened in analogy with the principle of accountability in data protection law. Similarly, it is discussed how positive duties to ensure fair outcomes for consumers are developed in consumer law. The analysis offers lessons for improving the ability of the three regimes to protect consumers by imposing greater responsibility on firms with greater market power and thus posing greater risks for consumer harm.

在竞争、数据保护和消费者法领域实现更智能的监管：为什么更大的权力应该伴随着更大的责任

基于概念性见解和案例调查结果，本文讨论了三种方式，可以通过调整实质性保护和执法机制来提高竞争、数据和消费者保护领域的监管有效性，以适应市场支配力的程度。由公司。首先，从竞争法对主导企业的特殊责任中汲取灵感，分析了如何将市场力量融入数据保护和消费者法的实质性保护范围。其次，根据消费者当局确定优先级和合作的经验，阐述了针对拥有市场支配力的公司更不对称和更明智地执行现有数据保护规则可以加强对数据主体的保护并刺激竞争。第三，与数据保护法中的责任原则相类比，探讨如何进一步加强竞争法对主导企业的特殊责任。同样，讨论了如何在消费者法中制定确保消费者公平结果的积极义务。该分析为提高三种制度保护消费者的能力提供了经验教训，通过对具有更大市场力量的公司施加更大的责任，从而对消费者造成更大的伤害风险。
