Mexico has made several efforts to design and implement a regulatory improvement policy over the past several years. The institutions involved in the better regulation policy have played a key role in enhancing regulatory quality. This includes the Federal Regulatory Improvement Commission (COFEMER), the Ministry of Economy, and the Ministry of Public Administration. Mexico now has two decades of experience in the application of Regulatory Impact Analysis (RIA). Over this period, it has continued to expand the scope of RIA, to refine and improve the specific requirements and to invest substantial resources in implementation. Recently, Mexico has adopted the internationally recognised Standard Cost Model, which has brought a renewed impetus across the federal government to reduce administrative burdens generated by formalities. There is also a thriving multi-level regulatory governance programme. As a result, Mexico is currently at a stage where positive results are being obtained. However, this is not the time to slow down; instead, further work should be fostered to step up to a new phase of regulatory quality which embeds an effective and profound regulatory improvement culture across the federal government.
