A rankings boycott that caused 15 of the top 25 schools in The Economist's MBA ranking to drop out is collapsing. Some 20 U.S. schools that shunned The Economist list have participated in the Financial Times 2021 ranking, including Chicago Booth, Northwestern Kellogg, Yale and UVA Darden. Nine European Schools that walked from The Economist also cooperated, including INSEAD, London Business School, Cambridge and Oxford.
