Multiplier = 1 / (MPS + MPT + MPM). MPS = 1 – MPC = 0.25. k = 1 / (0.25 + 0.1 + 0.05) = 1 / 0.4 = 2.5. ΔGDP = 40M × 2.5 = $100 million. Question 3 (International) Export price index rises from 100 to 120. Import price index rises from 100 to 110. Calculate Terms of Trade.

[ \textYED = \frac%\Delta QD%\Delta Y ] Repack Annotation: YED > 1 = luxury (income elastic). 0 < YED < 1 = necessity. ib economics hl formula booklet repack

"The more leakages (S, T, M), the smaller the multiplier."
