In the name of austerity, Mexican President Andrés Manuel López Obrador has slashed budgets, fired thousands of federal employees and cut salaries since he took office Dec. 1.

Now his party has decided that high-ranking government officials may not work in private sector industries they once regulated for 10 years after leaving government. The measure, aimed at ending the revolving door between the public and private sectors and cracking down on corruption, is one of the strictest in the world — well above the average three-year ban common among the 36 member countries of the Organisation for Economic Co-operation and Development.
