HWe have to give at least another 6-8 years to the ESCP MBA to see how it performs globally. If it shows consistent good performance then we can admit that it's a good MBA programme but at the moment we don't have much information about its "GLOBAL REPUTATION" having said that in France it's regarded a good MBA programme but then again many programmes are regarded good in the regional market but the global scenario is totally different.
This thread isn't really about global reputation: it's about one person who wants to work in the European luxury market. Their most immediate choices are things like the ESCP MBA and the Imperial College MSc in marketing. And the key variable here is really which programme has the best student, alumni and employer network to place them. Ranking are really useful, but it's mistaken to subordinate this role-focussed view to rankings. UCLA might be higher ranked and more enduringly than ESCP, but it's a weaker choice for this person's goal.
The ESCP and EAP MBAs have not been set up for success in the FT ranking. They are small programmes, reflecting the modest demand for monolingual anglophone talent in France, and they have lacked at times the scale and cohort structure needed for the FT ranking.
If you think that the Imperial MSc is a better option for entry into European luxe than the ESCP MBA, then please say a bit more about that.
