Answer to Problem 9.7P

The equilibrium price is $400, producer surplus is $20,000 and consumer surplus is $16,000.

Explanation of Solution

The demand for the broccoli is given by,

  Qd=1,0005P , and supply is as follows,

  Qs=4P80 ,

Equilibrium is a point where the demand and supply curve meet. Hence this point will be,

  Qs=Qd

  4P80=1,0005P

  P=$120 ,

Hence the equilibrium price is $120. Now substitute this value in above equation, we get,

  Qs=4P80 ,

  Q=4×12080

  Q=48080

  Q=400

Hence the equilibrium quantity is 400 units. Now the total expenditure is calculated as follows,

  E=P×Q ,

  =400×120 ,

  =$48,000

Now the consumer surplus is calculated by as follows,

  Consumer surplus=12×Base×Height ,

  =12×Q×(PmP*)

  =0.5(200120)(400)

  =$16,000

Hence the consumer surplus is $16,000.

Now the producer surplus is calculated below,

  Producer surplus=12×Base×Height ,

  =12×Q×(P*Ps)

  =0.5(12020)(400)

  =$20,000

Hence, the producer surplus is $20,000.

Economics Concept Introduction

Introduction:Consumer surplus is a difference between the amount which consumer actually pays and the amount which he is willing to pay.

Producer surplus is the difference between what the consumer is willing to accept for a given quantity of money or good and the how much a person actually receives by selling the good in the market at the prevailing prices.

Answer to Problem 9.7P

Hence the new consumer surplus is $12,000 and new producer surplus is $15,000.

Explanation of Solution

Suppose Q= 300, the total consumer surplus is calculated as follows,

  Consumer surplus=12×Base×Height ,

  =12×Q*×(PmP*)

  =0.5(200120)(300)

= =$12,000

Thus the new consumer surplus is $12,000 and it is decreased by the amount of $4,000. Now the producer surplus is calculated by as follows,

  Producer surplus=12×Base×Height ,

  =12×Q×(P*Ps)

  =0.5(12020)(300)

  =$15,000

Thus the new producer surplus is $15,000 and it is decreased by the amount of $5,000.

Answer to Problem 9.7P

As the equilibrium price increases, consumer surplus will decreased by $7,000 and producer surplus will increased by $8,800. If price will be $95 then producer surplus is decreased by $8,750 and consumer surplus is decreased by $11,562.50.

Explanation of Solution

Let the equilibrium price P = $140, then consumer surplus is calculated as follows,

  Consumer surplus=12×Base×Height ,

  =12×Q*×(PmP*)

  =0.5(200140)(300)

  =$9,000

As the equilibrium price is increased, the consumer surplus will decreased by $7,000.

Now the producer surplus will be,

  Producer surplus=12×Base×Height

  =12×Q×(P*Ps)

  =0.5(14020)(480)

  =$28,000

As the equilibrium price is increased, producer surplus will increased by $8,800.

Now assume the equilibrium price is $95 then the consumer surplus will be,

  Consumer surplus=12×Base×Height

  =12×Q*×(PmP*)=0.5(20095)(525)=$27,562.50

Thus consumer surplus is decreased by $11,562.50. Now the producer surplus will be,

  Producer surplus=12×Base×Height

  =12×Q×(P*Ps)=0.5(9520)(300)=$11,250

Thus, the producer surplus is decreased by $8,750.

Economics Concept Introduction

Introduction: Consumer surplus is the difference between the amount a consumer spends to purchase a commodity versus the amount he willingly wants to spend on the purchase.

Producer surplus is the difference between what the consumervoluntarily want to accept for a particular amount quantity of money or quantity of good and how much a person actually generates by selling the good in the market at the existing prices.

Answer to Problem 9.7P

Thus the consumer surplus is increased by $2,000 and producer surplus is increased by $2,500.

Explanation of Solution

Let equilibrium quantity is Q=450, then consumer surplus will be,

  Consumer surplus=12×Base×Height

  =12×Q*×(PmP*)

  =0.5(200120)(450)=$18,000

Thus the consumer surplus is increased by $2,000. Now calculate the producer surplus,

  Producer surplus=12×Base×Height

  =12×Q×(P*Ps)=0.5(12020)(450)=$22,500

Thus the producer surplus is increased by $2,500.

Here, the price shows in Y-axis and quantity shows in X-axis. Here fig (a) shows the equilibrium point at 400 and the equilibrium price is $120. The fig (b) shows that the equilibrium price is reduced to 300 from 400. The blue area shows the loss. The fig (c) shows the variation in equilibrium price from $120 to $95. The fig(d) represents the increased quantity from 300 to 450.
