Does going abroad slow your rise up the corporate ladder?

Here is a new study showing face time at headquarters is more important than an overseas experience. this was reported by BusinessWeek like this:

"The working paper, presented at the Academy of Management's annual meeting, held in Chicago Aug. 7-11, makes a good case that face time still counts for a lot in corporate life. Executives assigned to work abroad can lose out because they are unplugged from the valuable social networks at corporate headquarters—what Hamori and Koyuncu call "the out-of-sight, out-of-mind effect." This is consistent with previous studies that found that nearly half of repatriated executives left their company within two years of returning to their home country, largely because of concerns about career advancement.

The pair's advice for those who have their eyes on the corner office: Go ahead and take the job in Shanghai. But do it only for a year or two, and do it when you're young. And don't even think about jumping to another company when you get back."

and also by human resource executive online:

"The results show that executives with international-assignment experience take longer to reach the top echelon," the report states. "The more assignments they have and the longer time they spend outside their home organization, the slower they reach the CEO position."
