The Constant Growth Model
Commonly referred to as the Gordon Growth Model,the constant growth model assumes that dividends grow each period at a constant rate g,i.e.,D=D(1+g)and that this growth rate g is less than the expected rate of return r.This means that,given the first period dividend D and the growth rate g,all future dividends can be written.Notice that in this case the current share price is growth perpetuity,and so we have:
