The salaries for the HKUST - Kellogg program are stellar. Maybe these results are also skewed by PPP though.

Clearly the difference in salaries between countries has a high role in the ranking. For HEC probably Qatar students help a lot ;-)

It makes me wonder about some of the EMBA options, like Bradford in Manila, Cornell in Bogotá and Lancaster in Ghana. Countries with a high Gini coefficient or above average inequality in salaries could seriously tweak the PPP calculations.

It probably also has an effect on the salaries for some of the programs currently in the ranking (The BI Norwegian / Fudan program for example, and Hult, which reports average salaries of over $170k)
