This chapter highlights key insights from three expert reviewers mandated to: i) examine country practices for evaluating regulatory management tools and programmes and the collection of underlying data including advice to OECD countries for the evaluation of regulatory policy; ii) develop methodological practices that can be applied and replicated within OECD countries to assess the impact of sound regulatory management tools and programmes on the quality of regulation and on the real economy, and; iii) survey the literature on existing attempts at measuring the contribution of regulatory policy to improved performance in the real economy.
