US business schools led by the University of Pennsylvania’s Wharton produce the most influential academic research for decision makers in business and government, according to an FT ranking and analysis.

Nearly half of the 50 top-ranked global institutions with faculty publishing research that is widely read or cited by non-academics are based in the US, reflecting their substantial resources and dominance of publications in the English language.

Harvard, Stanford and the University of Chicago: Booth rank close behind Wharton in the FT Research Insights ranking (below), with Rotterdam School of Management, Erasmus University, scoring highest in Europe, in 14th place, immediately followed by Hong Kong University Business School and the University of Oxford: Sa?d.
