Q1. Let the demand and supply curve for some market be given by the equations below:
Demand: Qd = 8 - 2 * P
Supply: P = 2 + 4 *Qs
Answer the questions below using both graphs and algebra. You should show the solution both graphically and by solving the appropriate equations.
a. Find the equilibrium price and quantity.
b. Suppose that there is an increase in income. After the change in income the demand curve is given by Qd = 14 - 2 * P. Find the equilibrium price and quantity
c. What does this change in demand tell us about the good?
d. Suppose that a new and related good is introduced to the market. After the introduction of this new good the demand curve shifts to the left by 3 (i.e. at each price consumers are willing to buy 3 units less of the good). Find the new equilibrium price and quantity.
e. Using a class concept, can you think of an explanation for why the new good may have caused this change in demand?
Q2. The demand and supply curves for fixed gear bikes in Huntington are QD = 225 -1.5⋅ P and Qs =1.5⋅ P - 45 respectively.
A. Find the equilibrium price and quantity
B. What is the Consumer surplus at the market equilibrium calculated in part (1)
Producer surplus, and at the market equilibrium calculated in part (1)
Total welfare at the market equilibrium calculated in part (1)
