If Susan bought nine gallons of gasoline at $1.50 per gallon, the car wash cost $1, but if she bought 10 gallons of gasoline, the car wash was free. Given that Susan is going to get the car wash, the marginal cost of the tenth gallon of gasoline is
$0.50
An airline ticket from Seattle to Miami costs $525. A bus ticket is $325. Traveling by plane will take 5 hours, compared with 25 hours by bus. Thus, the plane costs $200 more but saves 20 hours of time. (Hint: Note how we are "thinking at the margin" here by looking at the changes.) Other things constant, an individual will gain by choosing air travel if, and only if, each hour of her time is valued at more than
$10 per hour
Currently, federal and state gasoline taxes (imposed statutorily on the sellers of gasoline) amount to about $.45 per gallon. Suppose the current price of gasoline is $1.20 per gallon, and that if the tax was not in place, the price would be only $.80.
A $.05 burden is being borne by sellers and $.40 by consumers.
(I) The height of the demand curve for a commodity indicates the maximum amount the consumer would be willing to pay for each unit of the good. (II) The height of the supply curve for a commodity indicates the minimum price the seller would accept for each unit of the good.
Both I and II are true.
Criteria of ideal economic efficiency requires that (I) all actions generating more social benefit than cost be undertaken and (II) no actions generating more social cost than social benefit be undertaken.
Both I and II are true.
Which of the following actions is consistent with the basic economic postulate (the guidepost) that incentives matter?

A politician votes against a pay raise for himself because most of his constituents are strongly opposed to it and would vote against him in the next election. Farmers produce less corn because corn prices have declined. all of the above
a freeze in Florida devastates the orange crop at the same time a new study is released showing the health benefits of vitamin C (leading consumers to want to buy more orange juice).

In the mid-1940s, the marginal income tax rate in the top income tax bracket was 94 percent. In the 1960s, the top rate was lowered to 70 percent, and in the 1980s, the top rate was again lowered to 28 percent. The data show that as a result of these tax rate reductions, tax revenue (particularly from the rich) increased. This is consistent with the idea illustrated with the
Laffer curve

When economists use the term ceteris paribus, they indicate
all other factors are assumed to be constant

allowing the price to rise, so gas was rationed to those willing to pay the most for it.
Over the past 20 years both the quantity of health care provided and health care prices have been rising rapidly. Economic theory would suggest that the observed data could best be explained as
an increase in demand, while supply remained relatively constant.

capitalism.
The absence of well-defined and enforceable private property rights often
causes difficulties for society due to externalities.
When collective decision making (the political process) is used to resolve economic questions regarding the allocation of resources,
central planning and political bargaining will replace market forces.
Which of the following would cause the price of automobiles to rise?
consumer income increase
Suppose there is an increase in the excise tax imposed on cigarettes, a good for which the demand is relatively inelastic. The short-run burden of the tax increase will be borne primarily by
consumers, because the increase in market price will be large relative to the increase in the excise tax.

desire for the good exceeds the amount that is freely available from nature

economy is operating at a point inside its production possibilities constraint.
The more elastic the supply of a product, the more likely it is that the burden of a tax will
fall on buyers.
The problem created when it is difficult to exclude nonpaying customers is called the
free-rider problem.
an income tax is regressive if
high-income recipients pay a lower percentage of their incomes in taxes than those whose incomes are low.
Which of the following is a guidepost to economic thinking?
incentives matter
"If gasoline were taxed, the price of gasoline would rise. Consequently, the demand for gasoline would fall, causing the price to fall to the original level." This statement is
incorrect--demand and quantity demanded are confused. The price increase would reduce quantity demanded, not demand.
"If income were redistributed in favor of the poor, we would eliminate scarcity." The preceding statement is
incorrect; it confuses the elimination of poverty with the elimination of the constraint imposed by scarcity.
An increase in the demand for a product will cause output to
increase and both the demand for and prices of the resources used to produce the product to increase.
The law of comparative advantage suggests that
individuals, states, and nations can all benefit if they trade with others.

is the value of the highest valued alternative forgone as the result of the choice.

What is an example that represents a normative statement?
its too hot in this room
A decrease in the supply of a good will
lead to an increase in the price of the good.
Consider two goods--one that generates external benefits and another that generates external costs. A competitive market economy would tend to produce too
little of the good that generates external benefits and too much of the good that generates the external cost.
New products provide a classic case of the consumer information problem. However, in some cases consumers partially solve the problem by trusting the "brand name" of the producer of the new product. Because firms spend millions of dollars advertising and maintaining their brand names, the likelihood of a "brand name" firm intentionally selling a dangerous or shoddy new product is
low because the firm with a brand name has a lot to lose if word spreads about bad consumer experiences.
Which of the following would most likely decrease the price of beef?
lower prices of grains used to produce cattle feed
The market pricing system corrects an excess supply by
lowering the product price and decreasing producer profits.

Which of the following "goods" is the best example of a pure public good?
national defense
Competitive Behavior
occurs as a reaction to scarcity.
When the price of a good is legally set below the equilibrium level, a shortage often results. This shortage
occurs because the price ceiling prevents the market mechanism from establishing an equilibrium price.
The highest valued alternative that must be given up in order to choose an action is called its
opportunity cost
In the absence of government intervention, goods with external costs tend to be
overproduced
The English philosopher John Locke argued that
people own themselves as well as the fruits of their labor and thus the role of government is to protect these natural rights of individuals.
Positive economics differs from normative economics in that
positive economic statements are testable, and normative statements are not.
A legal minimum wage is an example of
price floor
If there was an increase in the excise tax on beer, what would be the effect on the equilibrium price and quantity of beer?
price increases, quantity decreases

price increases, quantity increases
John advertises his used car for $3,000 in the newspaper. He would be willing to sell his used car for as low as $2,000. He is offered $2,600 for it from a buyer and accepts it. In this trade, John receives

Rent controls generally fix the price of rental housing below market equilibrium. Economic analysis suggests these controls
reduce the future supply of rental housing.

The owners of private property will
use their property in ways that others value because the market will generally reward them with profits (or a higher selling price) if they do so.
In economics, the benefit (or satisfaction) that an individual gets from an activity is called
