8. 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 5 years ago. Using that index, we find that this year’s real GDP is $15 trillion. Given those numbers, we can conclude that the current value of the index is: LO27.5

a. Higher than 100.

b. Lower than 100.

c. Still 100.
