16) Suppose that in 2007, Ford sold 500,000 Mustangs at an average price of $18,800
per car; in 2008, 600,000 Mustangs were sold at an average price of $19,500 per car.
These statements:
A.suggest that the demand for Mustangs decreased between 2007 and 2008.
B.suggest that the supply of Mustangs must have increased between 2007 and 2008.
C.suggest that the demand for Mustangs increased between 2007 and 2008.
D.constitute an exception to the law of demand in that they suggest an upsloping
demand curve.
17)
Refer to the diagram of the market for product X. Curve St embodies all costs
(including externalities) and Dt embodies all benefits (including externalities)
associated with the production and consumption of X. Assuming the equilibrium output
is Q2, we can conclude that the existence of external:
A.costs has resulted in an overallocation of resources to X.
B.benefits has resulted in an overallocation of resources to X.
C.costs has resulted in an underallocation of resources to X.
D.benefits has resulted in an underallocation of resources to X.
18) The post hoc fallacy and the correlation problem both relate to:
A.the calculation of marginal costs and marginal benefits of any economic activity.
B.the issue of determining causation.
C.the frequent inability of households and businesses to behave rationally.
D.the trade-off problem associated with competing goals.
