9. Suppose that the demand curve in a particular market is described by the following equation:

= 20 −

Where is the quantity demanded for the good or service and P is the price. If the price is currently $12, then the price elasticity of demand is ____________ and a reduction in price from $12 to $11 will _______________ total revenue.

A. 0.66; increase

10. The table below measures the distribution of wealth in the United States in 2010:

Household Quintiles

Share of Net

Worth (Wealth)

Cumulative

Share of

Households

Cumulative

Share of

Wealth

Bottom 20 percent 0.00 0.20 0.00

Second 20 percent 0.02 0.40 0.02

Third 20 percent 0.03 0.60 0.05

Fourth 20 percent 0.06 0.80 0.11

Top 20 percent 0.89 1.00 1.00

Note that these shares are not cumulative, but simply represent the share of wealth held

by each group. For example, the top 20 percent of the population has 89 percent of the

wealth. Using the Z-gradient approximation, the Gini coefficient for wealth in the United

States in 2010 is approximately:

A. 0.75

B. 0.80

C. 0.84

D. 0.89

11. The social savings approach to measure the importance of transportation developments

A. likely overestimates the true importance of transportation developments due to double counting.

B. likely underestimates the true importance of transportation developments because it only estimates the direct transportation savings and ignores

spillovers to other sectors of the economy.

C. has been found to be an accurate and unbiased measure of the importance of transportation developments,

D. likely overestimates the true importance of transportation developments due to measurement errors.

12. In 1870, half of all workers in the United States were employed in agriculture. Today, it is less than two percent. One piece of evidence contrary to the induced innovation hypothesis is:

A. the fact that the income elasticity of food is low.
