Question

Suppose that demand for chicken cesar salad can be expressed by
(the normal) demand function: Q=10-P. Further Suppose that the
(normal) supply function can be expressed: Q=2P-2.

Graph the Situation.

1. What is the initial equilibrium price?

2. What is the initial equilibrium quantity?

3. Suppose that a tax of $3/salad is levied on the producer.
What will be the new price paid by consumers after the tax?

4. What will be the new price received by the producer after
the tax?

5. What will be the tax revenue collected from this tax?

6. What is the deadweight loss associated with this tax?

7.By how much was consumer surplus reduced because of the
tax?

8. By how much was producer surplus reduced by this tax?

Answer #1

Sol : 1. Demand = Supply

10 - P = 2P - 2

12 = 3P

**$4 = P ( Equilibrium Price)**

Sol : 2. Q = 2P - 2

**= 8 - 2 = 6 (Equilibrium quantity
)**

Sol 3 : New Price paid by the consumer is $6 { q = 10 - P , Q = 4 , P = $ 6)

Sol 4: New price received by the producer after tax = $3 ( $6 consumer pays - $3 Tax)

Sol 5 : Tax revenue collected = 4 x 3 = $12

Sol 6 : Deadweight loss = 2 x 3 = $6

Sol 7 : Consumer loss is reduced by = $12 ( $2 x 6 = $12)

Sol 8 : Producer surplus reduced by = $6 ( $1 x 6 )

suppose the demand for chicken ceasar salads at home can be
expressed by the (normal) demand function: Q=10-P. Further suppose
that the (normal) supply function can be expressed: Q=2P-2. A tax
of $3/salad is levied on home(the producer) what will be the new
price paid by consumers after the tax?

A.1. a. Suppose the demand function P = 10 - Q, and the supply
function is: P = Q, where P is price and Q is quantity. Calculate
the equilibrium price and quantity.
b. Suppose government imposes per unit tax of $2 on consumers.
The new demand function becomes: P = 8 – Q, while the supply
function remains: P = Q.
Calculate the new equilibrium price and quantity. c.
Based on (b), calculate the consumer surplus, producer surplus, tax...

Suppose that the demand equation: P = 6 – Q and supply equation:
P = Q.
a. Calculate the price elasticity of demand at
equilibrium.
b. Calculate the equilibrium price and quantity, and consumer
surplus and producer surplus.
c. Suppose government imposes a unit tax of $1 on producers. Derive
the new supply curve and also calculate the new equilibrium price
and quantity.
d. Calculate tax revenue and the deadweight loss of this tax.

Using the following information to calculate a)-n). Demand: P =
45- ½ Q Supply: P = 2Q
a) P*=_________
b) Q*=_________
c) Initial Consumer Surplus=__________
d) Initial Producer Surplus=__________
e) Total Surplus =_________________
Now the government imposes a $15 per unit tax on consumers.
Calculate the following.
f) Tax Distorted Competitive Equilibrium Quantity=_____
g) Price (consumers pay with tax)=________
h) Price (producers get with tax)=________
i) Consumer surplus with tax=_________
j) Producer surplus after tax=__________
k) Tax Revenue=_____________
l) Total...

Suppose the demand curve for a good is Q =9 −pand the supply
curve is Q =2p. The government imposes a specific tax of =1 per
unit. What would be the equilibrium? What effect does the tax have
on consumer surplus, producer surplus and deadweight loss?

1). The market demand function for a good is given by Q = D(p) =
800 − 50p. For each firm that produces the good the total cost
function is TC(Q) = 4Q+( Q2/2) . Recall that this means
that the marginal cost is MC(Q) = 4 + Q. Assume that firms are
price takers.
(a) What is the efficient scale of production and the minimum of
average cost for each firm?
Hint: Graph the average cost curve first.
(b)...

The demand for skateboards in Vermillion is Q = 500−2P and the
supply curve is Q = 1/2 P. The government 2
decides to raise revenue by taxing consumers $25 for each
skateboard purchased.
(a) Graph the supply and demand curves and calculate the
consumer and producer surplus that would exist if there were no tax
in the market.
(b) Show how the tax will change the market equilibrium price
and quantity. Identify the price paid by consumers and the...

Suppose that in the short run, demand for chicken sausage is
given by Q = 100, 000 − 5, 000P and supply by Q = 80, 000 + 5,
000P, and that the equilibrium price and quantity in the market are
$2/lb. and 90,000 lbs. respectively.
(i) Suppose a $0.50 per-unit tax is imposed on consumers in the
market. Find the post-tax quantity, the price paid by consumers,
and the price received by producers.
(ii) How much of the tax...
