Macroeconomics can best be described as the
study of the large aggregates of the economy or the economy as a whole

positive and correct
Ben says that 'an increase in the tax on beer will raise its price.' Holly argues that 'taxes should be increased on beer because college students drink too much' we can conclude that:
Holly's statement is normative, but Ben's is positive
The economizing problem is:
the need to make choices because economic wants exceed economic means
The economizing problem is one of deciding how to make the best use of:
limited resources to satisfy virtually unlimited wants
When the economist says that economic wants are insatiable, this means that:
these wants are virtually unlimited and therefore incapable of complete satisfaction
The alternative combinations of two goods which a consumer can purchase with a given money income is shown by:
a budget line
The budget line shows:
all possible combinations of two goods that can be purchased, given money income and the prices of the goods
Any combination of good lying outside of the budget line:
is unattainable, given the consumer's income
Which of the following lists includes only capital resources and therefore no labor or land resources?
autos owned by a car rental firm; computers at the car rental agency; the vans that shuttle rental customers to and fro the airport
Which of the following in NOT a main function of the entrepreneur?
make routine pricing decisions
The production possibilities curve illustrates the basic principle that:
if all the resources of an economy are in use, more of one good can be produced only if less of another good is produced.
A production possibilities curve shows:
the maximum amounts of two goods that can be produced assuming the full use of available resources
When an economy is operating under conditions of full employment, the production of more of commodity A will mean the production of less of commodity B because:
resources are limited
Any point inside the production possibilities curve indicates:
that more output could be produced with available resources
Which of the following is NOT correct? A typical production possibilities curve:
specifies how much of each product society should produce
The negative slope of the production possibilities curve is a graphical way of indicating that:
to produce more of one product we must do with less of another
The production possibilities curve tells us:
the combinations of two goods that can be produced with society's available resources
Which one of the following statements is correct?
The central concept underlying the production possibilities curve is that of limited resources
Refer to the graph your brilliant instructor has graciously drawn on the board: This production possibilities curve is:
Concave to the origin because of increasing opportunity costs and Abell said so
Refer to the graph your brilliant instructor has graciously drawn on the board: The combination of computers and bicycles shown by point G is:
unattainable, given currently available resources and technology
Refer to the graph your brilliant instructor has graciously drawn on the board: If society is currently producing the combination of bicycles and computers shown by point D, the production of 2 more units of bicycles:
will cost 1 unit of computers
Refer to the graph your brilliant instructor has graciously drawn on the board: the combination of computers and bicycles shown by point F:
is attainable, but implies that the economy is not using all its resources
Refer to the graph your brilliant instructor has graciously drawn on the board: the movement down the production possibilities curve from point A to point E suggests that the production of:
both bicycles and computers are subject to increasing opportunity costs
The law of increasing opportunity costs exists because:
resources are not equally efficient in producing various goods
Opportunity cost is best defined as:
the amount of one product that must be given up to produce one more unit of another product.
Which of the following would be most likely to shift the production possibilities curve to the right?
an improvement in the literacy level and general level of education
Which of the following will shift the production possibilities curve to the right?
a technological advance that allows farmers to produce more output from given inputs
Other things equal, which of the following would shift an economy's production possibilities curve to the left?
a law requiring mandatory retirement from the labor force at age 55
Which of the following statements, if any, is correct for a nation that is producing only consumer and capital goods?
other things equal, the more capital goods a nation produces, the greater will be its future growth rate
All of the following could immediately or eventually lead to an inward shift of a nation's production possibilities curve, EXCEPT:
an increase in the average skill level of all occupational groups
A nations production possibilities curve might shift to the left (inward) as a result of:
the depletion of its soil fertility due to overplanting and overgrazing
Which of the following might shift a nation's production possibilities curve inward?
devastating by war
Free products offered by firms:
may or may not be free to individuals, but are never free to society
The assertion by economists that 'there is not free lunch'
remains true even for good given away free by firms
The "after this, therefore because of this" fallacy states that:
because event A precedes event B, A is necessarily the cause of B.
The safest way for an individual to leave a burning theater is to run for the nearest exit;it is therefore also the nest means of escape for a large audience. This assertion illustrates the:
fallacy of composition.
Which of the following has to do with the idea that generalizations that apply to individuals are also always valid for a group?
the fallacy of composition.
The fallacy of composition states that:
generalizations pertaining to individuals always apply to the group.
If you leave a football game at the end of the third quarter, you will avoid traffic and get home more quickly. Therefore, everyone should leave the game early. This assertion illustrates the:
fallacy of composition.
Which of the following has to do with the problem of distinguishing cause and effect in economic reasoning?
the post hoc fallacy.
Which of the following best illustrates the post hoc fallacy?

The post hoc fallacy and the correlation problem both relate to:
the issue of determining causation.
A caller to a radio talk show states that protesters against globalization are a collection of "anarchist punks, naive college students, and trade union radicals." This is an example of"
A study found that the incidence of skin cancer increases along with the amount of time people work under fluorescent light, leading some people to conclude that fluorescent lighting is a cause of skin cancer. But further analysis found that people who work in offices, where fluorescent light is common, suffer more sunburn on their vacations than other workers. The sunburns, not the fluorescent light, were the cause of higher incidence of skin cancer. The original conclusion illustrates:
confusion of correlation and causation.
