Consider the following equations:
SUPPLY: Q=10+2P
DEMAND: Q=60-3P
a) Compute the consumer's surplus at equilibrium. Show it on a graph.
Setting QD=QS
60-3P=10+2P
60-10=2P+3P
50=5P
P=10
Q=10+2(10)=30
When QD=0,P=60/3=20
CS=0.5X30X(20-10) = 150
Consider the following equations: SUPPLY: Q=10+2P DEMAND: Q=60-3P a) Compute the consumer's surplus at equilibrium. Show...
Consider the following equations: SUPPLY: Q=10+2P DEMAND: Q=60-3P b) If the government imposes a ceiling price (P max) of $8.50 per unit. Would it result in a shortage or a surplus or a surplus? Show in the graph.
Consider the following equations: SUPPLY: Q=10+2P DEMAND: Q=60-3P c) Assume there is not enough control from the authorities, so there is a black market. Compute the black market price. Show it on the graph.
Consider the following equations: SUPPLY: Q=10+2P DEMAND: Q=60-3P d) The government imposes a tax of 2 dollars per unit produced to the suppliers. Compute the new equation and graph.
The demand and supply curves are given by q=130−3p and q=2p−60, respectively; the equilibrium price is $38 and the equilibrium quantity is 16 units. A sales tax of 2% is imposed on the consumer. (a) Find the equation of the new demand and supply curves. b) Find the new equilibrium price and quantity. (c) How much is paid in taxes on each unit? How much of this is paid by the consumer and how much by the producer? (d) How...

Question 1: In a perfectly competitive market, the demand curve is given as: Q=100-5P, the supply curve is given as Q=3P-12. Compute the total social surplus of this market. If the government impose a tax on the producers, and the tax rate is $2 per unit produced. What is the deadweight loss? If the government impose a tax on the consumers, and the tax rate is $2 per unit purchased, graphically show the change in the market equilibrium and the...
Consider a market where supply and demand are given by Q(s) = -10 + 3P(x) and Q(d) = 130 – 2P(x) where P(x) is the price of good X. Assume that the government imposes a price ceiling of $50. What is the impact on the market (make sure to calculate the appropriate surplus or shortage, if needed)?
Suppose the demand for video games is q=40-2p and the supply is q=3p, and there is a quantity tax, $5 per unit of the video game. 1. Compute the equilibrium quantity and price before the tax; 2. Compute the equilibrium quantity and prices for both buyers and sellers after the tax; 3. Compute the total tax revenue raised by the government and the fraction of tax the buyers need to paytax paid by buyers/total tax revenue). 4. Compute the dead...
