This chapter presents the OECD Framework for Regulatory Policy Evaluation. It builds on the findings of the expert papers and discussions with delegates from the OECD Regulatory Policy Committee. The Framework aims to assist countries in evaluating their regulatory policy at every step in the process; from design to implementation and subsequently to the achievement of broader objectives. It also describes how different types of indicators can be used to create an overarching method of evaluating regulatory policy performance. The full application of the Framework requires data and information on the design, implementation and results of regulatory policy. This includes input (resources committed to regulatory policy), process (formal requirements for good regulatory policy), output (actual implementation of good practices), intermediate outcomes (improvements of regulations due to implementation of good practices) and outcomes (achievement of strategic objectives).
