Country X's export price index rose by 10% and its import price index rose by 10%, while the quantity of its exports rose by 20% (base period = 100 for all). Its income terms of trade (Px/Pm x Qx, with base 100) in the later period are:

Income terms of trade are 120. The net barter terms are unchanged at 100 because both price indices rose equally by 10 percent, and the export quantity index of 120 then scales this to 120, showing greater import capacity from exports.

  1. A110
  2. B120Correct
  3. C100
  4. D132

Explanation

Income terms of trade = (Px/Pm) x Qx. Px/Pm = 110/110 = 1, so NBTT stays at 100. Multiplying by export quantity index 120/100 gives 100 x 1.20 = 120. Option D (132) wrongly multiplies the 10% price rise into the result as well. Option C ignores the rise in export volume.
