Exercise 2

Suppose that this year's nominal GDP is $16 trillion. To account for the effects of inflation, we construct a price-level index in which an index value of 100 represents the price level five years ago. Using that index, we find that this years real GDP is $15 trillion. Given those numbers, we can conclude that the current value of the index is:
A) Higher than 100.
Bthan 100.
C) Still 100.
