The 2012 Financial Times executive MBA ranking highlights the merits of sharing culture, experience and expertise, with five cross-continental joint programmes topping the tables.
The ranking is based on a survey of business schools and alumni who graduated in 2009, rated by criteria ranging from career progression and school diversity to idea generation.
In first place for the fourth consecutive year is the joint EMBA run by the Kellogg school in Illinois and the Hong Kong University of Science and Technology. Its alumni have the highest average salary, are top for aims achieved, have the second best work experience and comprise one of the most diverse cohorts.
