• For the simple-interest method, we have i(t)= (1+rt)−(1+ r(t−1)) 1+r(t−1) = r 1+r(t−1), which decreases when t increases. • For the compound-interest method with annual compounding (i.e., m =1), we have (denoting r(1) = r) i(t)= (1+r)t −(1+r)t−1 (1+ r)t−1 = r, which is the nominal rate of interest and does not vary with t. 20
