Derivatives Forward Question question, position, afternoon, positive, index

lunarfollies

In one of the schweser mock exams, i think book 2 afternoon sessions there's a question that asks about the growth of the dividend yield.

F = S x e power (rf - Dy ) n/N (index)

Will it be positive for the person holding the long position to have a higher dividend yield growth?

I don't really find it positive however schweser says it is ..

Any advice?
