Bmillan,
You might take this ranking with a grain of salt. The Economist is one of my favorite publications, but their MBA ranking (EIU) system lacks credibility. Eighty percent of the weight of their ranking comes from unaudited information that the schools provide. And the schools come up with some pretty egregious stuff: For example, if I recall correctly, HEC gives an
average salary on exit of $124,000. Hmmm...
You know what they say: garbage in, garbage out. So, IESE gets ranked 1st, Wharton 9th, Vierick Leuven (????) 10th, INSEAD 23rd, Oxford 47th, UCLA 50th, etc, etc.
Unfortunately, I haven't seen an international ranking system that really nails it. Until then, I would recommend that prospective MBA candidates do their homework rather than expect dodgy figures to make the decision easy: figure out why you want an MBA and then talk with prospective employers, look at the (auditable) placement statistics, and speak with the schools. Oxford students land great jobs, and did so even during the worst economy in recent memory (see the link below). That's all that matters to me.
