b)when the supply curve has a zero elasticity
c)when the demand curve has a zero elasticity
d)when the tax is collected from the seller

The following three questions refer to the accompanying diagram of a competitive market.

Refer to Figure 3 above. A per unit tax is imposed on consumers. The initial price and quantity are P0 and Q0, respectively. After the tax is imposed, the equilibrium quantity is Q1, firms receive the price Ps, and consumers pay the price Pd.

2.Area C + D + F + G is
a)the tax revenue collected by the government
b)the total value that consumers receive from their purchases c)the fall in producers' surplus
d)the deadweight loss due to the tax

3.Refer to Figure 3 above. Which is the deadweight loss from the imposition of the tax? a)E
b)E + H
c)H
d)J
e)E + H + J
