Answer:
0.95
Explanation:
Given that,
Market demand for wheat: Q = 100 − 2p + 1pb + 2Y
price of wheat, p = $2
price of barley, pb = $3
Income, Y = $1000
Q = 100 − 2p + 1pb + 2Y
= 100 - (2 × 2) + (1 × 3) + (2 × 1,000)
= 100 - 4 + 3 + 2,000
= 2,099
Differentiating Q with respect to Y,
dQ/dY = 2
Income elasticity of wheat:
= (dQ/dY) × (Y ÷ Q)
= 2 × (1,000 ÷ 2,099)
= 0.95
