Zorluk: ZorRevenue Concepts and Relationships

A firm operating in an imperfectly competitive market expands its output from 2020 units to 2525 units, causing its average revenue to fall from ₦50\text{₦}50 to ₦44\text{₦}44. What is the firm's marginal revenue per unit over this range of output?

  1. ₦20\text{₦}20Cevap
  2. B
    ₦44\text{₦}44
  3. C
    ₦100\text{₦}100
  4. D
    ₦6\text{₦}6

Cevap

The marginal revenue per unit over this output range is ���20\text{���}20.
Total revenue at 2020 units is 20×₦50=₦1,00020 \times \text{₦}50 = \text{₦}1,000, and at 2525 units it is 25×₦44=₦1,10025 \times \text{₦}44 = \text{₦}1,100. The increase in total revenue is ₦100\text{₦}100 across 55 units, yielding a marginal revenue of 1005=₦20\frac{100}{5} = \text{₦}20 per unit.

Adım Adım Çözüm

1
Calculate initial total revenue (TR1TR_1) and final total revenue (TR2TR_2)
TR1=Q1×AR1=20×50=₦1,000TR_1 = Q_1 \times AR_1 = 20 \times 50 = \text{₦}1,000 and TR2=Q2×AR2=25×44=₦1,100TR_2 = Q_2 \times AR_2 = 25 \times 44 = \text{₦}1,100
Total revenue is the product of output quantity and average revenue (price).
2
Determine the change in total revenue (ΔTR\Delta TR) and the change in quantity (ΔQ\Delta Q)
ΔTR=1,100−1,000=₦100\Delta TR = 1,100 - 1,000 = \text{₦}100 and ΔQ=25−20=5 units\Delta Q = 25 - 20 = 5\text{ units}
Marginal revenue measures the rate of change of total revenue with respect to output.
3
Calculate marginal revenue (MRMR)
MR=ΔTRΔQ=1005=₦20MR = \frac{\Delta TR}{\Delta Q} = \frac{100}{5} = \text{₦}20
Marginal revenue formula is MR=ΔTRΔQMR = \frac{\Delta TR}{\Delta Q}.
