Suppose the market demand function is given by D(PD) =60 − PD and S(PS) = 2PS.

a. (2 points) Find the market equilibrium without taxes (that is,when PD = PS).

b. (3 points) Suppose now the supplier is required to play a per unit tax of t = 3. Draw a graph to show the change in the supply curve. Find the equilibrium quantity and prices, q ∗ , P ∗ S , and P ∗

D.How much of the per unit tax is passed on to the consumer?

(Hint: in this case, the vertical axis is the demand price.)

c. (2 points) Suppose now the demander is required to play a per unit tax of t = 3. Draw a graph to show the change in the demand curve. Find the equilibrium quantity and prices, q∗, P∗S,and P∗

D. (Hint: in this case, the vertical axis is the supply price.)

Compare your answers in parts b and c.

d. (5 points) Calculate the change in consumer’s surplus, change in producer’s surplus, tax revenue, and deadweight loss as a result of the policy change. Illustrate them on a graph.
