Question

A demand curve and supply curve for video games are given respectively as follows:

QD= 72‒ 2P + 2M

QS = 8 + P

Where M represents consumer income. Suppose that last year, consumer income was M= $40. Find the equilibrium price and quantity of video games at that income level. In addition, suppose that this year, consumer income is M= $55. Find the equilibrium price and quantity of video games at this new income level. Draw the graph of both the demand and supply curves before and after the change in income. Clearly label any shifts or movements, as well as all curves and equilibrium points as well as numerical values for the equilibrium prices and quantities.

Answer #1

1. Consider a demand curve of the form QD = 40 - 2P, where QD is
the quantity demanded and P is the price of the good. The supply
curve takes the form of QS = -4 + 2P, where QS is the quantity
supplied, and P is the price of the good. Be sure to put P on the
vertical axis and Q on the horizontal axis. a. What is the
equilibrium price and quantity? Draw out the supply...

The demand and supply for a good are respectively QD = 16 – 2P +
2I and QS = 2P – 4 with QD denoting the quantity demanded, QS the
quantity supplied, and P the price for the good. Suppose the
consumers’ income is I = 2. 6) Determine the price-elasticity of
demand if P = 2. 7) Determine the income-elasticity of demand if P
= 2. 8) Determine the price-elasticity of supply if P = 4. 9)
Determine consumers’...

Question 2. The market supply and demand curves for a product
are:
QS=0.5P (supply curve)
QD=60–2P (demand curve)
where Q is the quantity of the product and P is the market
price.

Suppose the demand curve is given by Qd=75-5P and the supply
curve is given by Qs=P-3. SHOW YOUR WORK in the space below (type
it out, line by line), and solve for the equilibrium price, the
equilibrium quantity, the consumer surplus, the producer surplus,
and the total surplus.

a) Find the equilibrium price and quantity. Suppose that the
government decided they wished to levy a $2 tax on suppliers.
b) Find the new price paid by the consumer and the price
received by the seller.
c) Based on the tax sharing burden by both the consumer and the
seller, comment on the relative...

The demand and supply curves for a good are given by QD = 50 –
2P and QS = P – 1.

price.
Calculate the price elasticity of supply at the equilibrium
price.

b. At the market equilibrium, what is the price elasticity of
demand?
