Answer:
Follows are the solution to the given question:
Explanation:
For point a:
When efficient level Q1 is produced, the dollar amount of the total surplus (production company excess plus its consumer excess) is provided
Surplus consumer area + Surplus manufacturer area
= Triangle Area ABC:
[tex]= \frac{1}{2}\times ac \times Q_1 \\\\= \frac{1}{2}\times (85 - 5) \times 20 \\\\= \frac{1}{2}\times 80 \times 20 \\\\= \$ 800[/tex]
So, the total amount of surplus in 5.4a is $800. The dollar value of its surplus is calculated by the output Q1
[tex]= \frac{1}{2}( \text{choke price} - \text{equilibrium price}) \times \text{equilibrium quantity}\\\\= \frac{1}{2}\times (85 - 45)\times 20 \\\\ = \frac{1}{2}\times 40 \times 20 \\\\=$400[/tex]
so, the consumer surplus = $400.
For point b:
Whenever the output level Q2 is produced, the unit price of the loss of demise is calculated by the sheltered region in figure 5.4 a
= Triangle Area dbe:
[tex]= \frac{1}{2} \times(de) \times (Q_1-Q_2) \\\\= \frac{1}{2} \times (55 - 35) \times 5 \\\\= \frac{1}{2} \times (20) \times 5 \\\\ = \$50[/tex]
So, the deadweight loss = $50. The total surplus for output Q2 is determined by the trapezium suitable area
[tex]= \frac{1}{2} \times (ac + de) \times Q_2\\\\= \frac{1}{2} \times (80 + 20) \times 15\\\\= \frac{1}{2} \times 100 \times 15\\\\= \$ 750.[/tex]
So, the total surplus is $750
For point c:
The value of its deadweight loss in dollars in Q3 can be seen in figure 5.4b in the shaded area provided by
= The triangle area bfg
[tex]= \frac{1}{2} \times (fg) \times (Q_3-Q_1)\\\\= \frac{1}{2} \times (59 - 31) \times 7 \\\\= \frac{1}{2} \times 28 \times 7 \\\\ = \$98[/tex]
The deadweight loss is $98.
The total excess at output level Q3 is calculated by removing the deadweight loss from the maximum excess. It implies a quantity of between $800 - $98 = $702.
In the incident of oversupply, the consumer supply is, therefore, $702.
