As a small, open economy, Mauritius needs a well-performing regulatory system that provides necessary protections while enabling the development of trade and investment and limiting administrative burdens. A robust regulatory impact assessment (RIA) framework can enhance Mauritius' business environment and attractiveness as a trade and investment partner. In particular, RIA can help Mauritius strengthen its rule-making framework, for example by increasing scrutiny and taking a more evidence-based approach to rulemaking. This report presents OECD recommendations on to how establish a RIA framework in Mauritius. These recommendations are based upon an analysis of the country's strengths and challenges, as well as extensive engagement with stakeholders. The recommendations also draw on lessons learnt from RIA implementation in a range of countries and an initial benchmarking of RIA-related best practices and guidance material from various relevant jurisdictions.
