Question 1

(a) Discuss how microeconomic theory can help to explain the effects of lowering the minimum wage for teenage employees in the retail industry (b) How is the usefulness of a theory evaluated

Question 2

(a) Distinguish between positive analysis and normative analysis. (b) The following statements were overheard in a conversation between two students.

(b) Illustrate the equilibrium using a diagram.

Question 4

The market demand function for is given by the following equation:

QC = 500 - 200PC + 0.25Y + 100PW

The current values are: PC= $5, Y = $10 000, and PW= $2.50.

(a) Find the quantity demanded.
(b) Calculate the price elasticity of demand. Comment on the price elasticity coefficient. (c) Calculate the income elasticity of demand. Comment on the nature of the commodity. (d) Calculate the cross-price elasticity of demand.
