Korea has significantly improved its regulatory policy system over the recent years. Ex post evaluation is mandatory for all regulations developed by the executive and central ministries are required to outline the intended evaluation plan as part of each RIA. Korea has been putting effort into systematically implementing this approach in practice. RIAs are undertaken for all subordinate regulations in Korea and for the primary laws initiated by the executive. To increase the quality of RIA and reduce the burden of preparing RIA statements, e-RIA was launched in May 2015, providing public officials with the data necessary for cost-benefit analysis.
