Purpose of Review: This systematic literature review evaluates the potential of gambling monopolies to affect gambling harms. It compares the occurrence of gambling harms in jurisdictions with gambling monopolies to jurisdictions with license-based regimes. Recent Findings: The review identified 21 publications concerning three gambling-related harm indicators: problem gambling prevalence, total consumption, and the appearance of conflicts of interest. Due to the dearth of literature, concept papers and older publications were also included. Summary: Results show that there is a paucity of empirical research on the effectiveness of different regulatory regimes in affecting gambling harms. Available research demonstrates that monopolistic regimes appear to perform somewhat better in terms of problem gambling prevalence and total consumption but may also be more prone to conflicts of interest than license-based regimes. Monopolistic configurations also differ between themselves, and issues such as availability, accessibility, product range, scope of preventive work, monitoring, as well as the recognition of the public health approach may better predict the levels of harm in society than the existence of a monopoly.
