Question 2

Between 1950 and 2017 the productivity of wheat farmers in the United States more than doubled. This means that
A) the amount of land and other resources devoted to wheat production more than doubled.
B) the incomes of wheat farmers more than doubled.
C) the total amount of wheat produced more than doubled.
D) the amount of wheat produced by the average farmer more than doubled.

Accepted Answer

Productivity refers to the amount of output per unit of input. In this case, the productivity of wheat farmers doubled, which means that they were able to produce twice as much wheat with the same amount of inputs (land, labor, machinery, etc.) The doubling of productivity does not necessarily mean that the total amount of wheat produced or the amount of resources devoted to wheat production also doubled. Therefore, the correct answer is D - the amount of wheat produced by the average farmer more than doubled.

Question 8

If a soda tax is implemented and demand for soda is price elastic, the decline in equilibrium quantity would be ________ and the increase in equilibrium price would be ________ than if demand were inelastic.
A) larger; larger
B) larger; smaller
C) smaller; larger
D) smaller; smaller

Accepted Answer

When demand is price elastic, consumers are more sensitive to changes in price and therefore the decline in equilibrium quantity would be larger compared to when demand is inelastic. However, the increase in equilibrium price would be smaller as consumers are more likely to switch to substitute goods.

Question 12

The demand for most farm products is relatively inelastic. All else constant, what is the effect on farm revenues as a result of the introduction of new and better farm equipment which increases productivity?
A) Farm revenues increase.
B) Farm revenues decrease.
C) Farm revenues remain constant because consumers will not increase their consumption of farm products by much.
D) Farm revenues could increase or decrease depending on the cost of this new equipment.

Accepted Answer

Question 13

A soda tax is more effective at reducing soda consumption when demand is price ________ and is more effective at raising tax revenue when demand is price ________.
A) elastic; elastic
B) elastic; inelastic
C) inelastic; elastic
D) inelastic; inelastic

Accepted Answer

A soda tax is more effective at reducing soda consumption when demand is price elastic, meaning that consumers are sensitive to changes in price and will decrease their consumption in response to a price increase. On the other hand, a soda tax is more effective at raising tax revenue when demand is price inelastic, meaning that consumers will continue to purchase soda even with a price increase. Therefore, option B is the correct answer as a tax on soda will work best in reducing consumption of soda and raising tax revenue when demand for soda is elastic.

Question 16

Assume that a 2 cent per ounce percent soda tax led to a large increase in its price and only a small decrease in the quantity of soda demanded. Economic analysis would lead one to conclude that
A) soda should be taxed because the benefits of the tax would exceed the costs.
B) soda should not be taxed because the benefits are uncertain.
C) soda should not be taxed on ethical grounds since ethical benefits and costs can't be measured.
D) the benefits of taxing soda is a normative issue. Economic analysis can be used to contribute to discussion of this issue but cannot decide it.

Accepted Answer

Economic analysis can provide information on the effects of a soda tax, but ultimately the decision to tax soda is a normative issue based on ethical and political considerations that cannot be fully decided through economic analysis alone.

Question 18

If a soda tax is implemented and demand for soda is price elastic, the effect on discouraging soda consumption would be ________ and ________ tax revenue would be collected than if demand were inelastic.
A) larger; more
B) larger; less
C) smaller; more
D) smaller; less

Accepted Answer

If demand for soda is price elastic, a soda tax would lead to a larger decrease in consumption as consumers are more responsive to changes in price. This would result in less tax revenue collected as overall sales would decrease, but the tax rate remains the same. Therefore, a larger effect on discouraging soda consumption would occur, but less tax revenue would be collected than if demand were inelastic.
