Consider the following functions of the market for a good x. Q = 20 P - 1000. Q = 6000 - 30 P.
Identify the demand and the supply functions
Find the equilibrium price and quantity both algebraically and graphically.
What would happen ( Surplus or shortage) if this market was imposed :
A price ceiling of 100?
A price ceiling of 200?
A price floor of 180?
A price floor of 50?
Calculate the elasticities of demand and supply at the following prices
Price P = 75
Price P =150
Are your results in line with the theory of elasticity at lower (higher) prices for both demand and supply?
Consider the following market for good x (finely divisible). Q = 2 P; and ; Q=16/√P; Identify the demand and the supply functions
Find the equilibrium price and quantity
What would happen (Surplus or shortage) if this market was imposed:
A price of 5 dollars per unit?
Calculate the elasticity of demand at the price P= 8. (Elastic or Inelastic? Why?)
Consider the following cost and benefit functions: C(X, Y) = 150 X + 30 X2. B(X, Y) = 400 X - 10 X2 + 200 Y - 5 Y2 + 10 X Y . For Y = 5

Graph the following indifference curves for the given utility levels:
U (x, y) = x + y for U = 5, 6, 7, , 8, 9 and 10. (What kind of relationship exists between these goods? Substitutes, Complements?
U (x, y) = min { 3x, y} for U = 3, 6, 9, 12, and 15. (What kind of relationship exists between these goods? Substitutes, Complements?
Consider the utility function for a utility maximizing individual consuming two goods X and Y. U (X,Y) = X2Y + 15. This person pays 3 dollars for good X and 5 dollars for good Y with an income of 150 dollars. ( 3 X + 5 Y ≤ 150) Budget constraint.
