1) An increase in input productivity will:
A.shift the aggregate supply curve leftward.
B.reduce the equilibrium price level, assuming downward flexible prices.
C.reduce the equilibrium real output.
D.reduce aggregate demand.
2) Suppose population A, consisting of Al, Bob, Curt, Doris, and Ellie, receive annual
incomes of $5,000, $2,500, $1,250, $750, and $500, respectively.
Refer to the above information. What percentage of total income is received by the
lowest 60 percent of the income receivers in population A?
A.60
B.50
C.25
D.18
3) compared to coffee, we would expect the cross elasticity of demand for:
a.tea to be negative, but positive for cream.
b.tea to be positive, but negative for cream.
c.both tea and cream to be negative.
d.both tea and cream to be positive.
4)
Refer to the above diagrams for two separate product markets. Assume that society’s
optimal level of output in each market is Q0 and that government purposely shifts the
market supply curve from S to S1 in diagram (a) and from S to S2 in diagram (b). The
shift of the supply curve from S to S2 in diagram (b) might be caused by a per unit:
A.subsidy paid to the producers of this product.
B.tax on the producers of this product.
C.subsidy paid to the buyers of this product.
D.tax on the buyers of this product.
