What are the consequences of leveling in lower level areas?

I know guild wars 2 manages to scale (down only) your level acording to the area maximum level.

How will the experience for a level 30 player for instance, leveling on a level 5-15 area, be calculated ? Will the scalled down level 30 player level up as fast as the lvel 5-15 players in that area ?

Thanks in advance

EDIT: As per january 28th, the developers made some changes in the way level downscaling works. According to the article, the net effect is to make downscaling both more challenging /and/ more rewarding.

my experience when playing with my lvl. 15 friend and my level 50 character: I get less money from events and quest than in the higher area. But the drop seems to be balanced to my level and I level up as fast as my friend (approximately). And it's way more fun than playing alone.
