Price fixing and corruption cause immense economic damage. Measures of competition law com-pliance present a possibility to prevent price fixing and cartelisation. Taking a psychological perspective may help to understand which individual, group, and organisational factors may foster compliance. We explore factors driving compliance and propose the psychological onion model of competition law compliance. The model contains individual, group, and organisational factors determining competition law compliance. These factors are influenced by environmental factors. Within each layer of the onion model, we focus on particularly relevant examples by discussing implicit motives and core self-evaluations (individual), justice (group), and corporate social responsibility (organisation) in detail. Practical recommendations for the establishment of compliance structures in organisations are given, accompanied by theoretical considerations and future research directions.
