I am primarily concerned with the FIN area at Buffalo: http://mgt.buffalo.edu/degree-programs/phd-in-management/finance/alumni.html. Aren't these impressive enough?
Sorry for the typo. The approximately 150 should also include R2 schools and overseas schools considered as being equivalent to R1 and R2 schools . Even if the two you mentioned are excluded (thank you for pointing this out; even I didn't know myself), the number should still hold.
HK and Singapore schools are as competitive as top schools in North America. There are several very strong universities in Turkey, and they have faculty with degrees from top schools worldwide. If you do not believe, go check. As for South America, I don't know about it.
再补充一下。现在找工作很多人已经不把目光仅仅盯在美国。先说新港学校,难度和美国 TOP School 相当,更何况这些学校一般仅考虑 TOP 学校的毕业生,这是事实吧。回国内的,如果是清北一类,大家知道清北一类招海外PhD一般只考虑美国 Top 30或其他国家相当排名的。很多回国是自己的选择。加拿大的好学校除了那几所最好的,其他如 Alberta, McMaster等也很不错,足以胜过很多美国所谓R1。英国名校也不少,besides LBS, 在UTD TOP 100就有六家. 法国德国好学校也不少。
