question
Points outside (or beyond) the PPF are
answer
unattainable.
question
If increasingly more units of good Y must be given up as each successive unit of good X is produced, then the PPF for these two goods is
answer
a downward-sloping curve that is bowed outward.
question
Consider the following combinations of guns and butter that can be produced: 0 guns, 20,000 units of butter; 5,000 guns, 15,000 units of butter; 10,000 guns, 10,000 units of butter; 15,000 guns, 5,000 units of butter; 20,000 guns, 0 units of butter. The PPF between guns and butter is
answer
a downward-sloping straight line.
question
Consider two points on the PPF: point A, at which there are 10 apples and 20 pears, and point B, at which there are 7 apples and 21 pears. If the economy is currently at point A, the opportunity cost of moving to point B is
answer
3 apples.
question
Suppose the economy goes from a point on its production possibilities frontier (PPF) to a point below that PPF. Assuming that the PPF has not shifted, this could be due to
answer
an increase in unemployment of some resources.
question
An increase in the quantity of resources
answer
shifts the PPF rightward.
question
Which of the following is an illustration of the law of increasing opportunity costs?
answer
As more cars are produced, the opportunity cost of each additional car is greater than for the preceding unit.
question
The PPF between goods X and Y will be a downward-sloping
answer
curve that is bowed outward if increasing opportunity costs exist.
question
A PPF is more likely to be a downward-sloping curve that is bowed outward than a downward-sloping straight line because most resources are
answer
better suited for the production of some goods than others.
question
Which of the following statements is false?
answer
If there are only two goods, guns and butter, it is possible to produce more of both goods if the economy is currently operating at a productive efficient point.
question
An economy is productive efficient if it produces
answer
maximum output with given resources and technology.
question
Refer to the image. The PPF illustrates
Refer to the image. The PPF illustrates
answer
constant opportunity costs between guns and butter.
question
Refer to the image. A movement from point B to point D
Refer to the image. A movement from point B to point D
answer
could only happen through economic growth.
question
Refer to the image. The opportunity cost of moving from point B to A is
Refer to the image. The opportunity cost of moving from point B to A is
answer
20,000 units of butter.
question
Farming today in the U.S. is __________ productive compared to a century ago, resulting in there being __________ farmers today than at the turn of the previous century.
answer
much more; fewer
question
Within the production possibilities frontier (PPF) framework, choice is depicted by the
answer
need to select among the points making up the PPF.
question
In an eight-hour day, Andy can produce either 24 loaves of bread or 8 pounds of butter. In an eight-hour day, John can produce either 8 loaves of bread or 8 pounds of butter. The opportunity cost of producing 1 pound of butter is
answer
3 loaves of bread for Andy and 1 loaf of bread for John.
question
Jose has one evening in which to prepare for two exams and can employ two possible strategies: Strategy Score in Econ Score in Stat A 94 79 B 77 90 The opportunity cost of receiving a 94 on the Economics exam in terms of the number of points on the Statistics exam is
answer
11
question
The law of increasing opportunity costs states that as
answer
more of a good is produced, the higher the opportunity costs of producing that good.
question
What is the reason for the law of increasing opportunity costs?
answer
Resources have varying abilities and those with lower opportunity costs of producing a good will be used to produce it before resources with higher opportunity costs produce it.
question
If an economy is operating on its production possibilities frontier (PPF), are there any unemployed resources in the economy?
answer
No, because if there were any unemployed resources the economy would be producing below its PPF.
question
If Sean can bake bread at a lower opportunity cost than Jason, and Jason can produce paintings at a lower opportunity cost than Sean, it follows that
answer
Sean has a comparative advantage in baking bread and Jason has a comparative advantage in producing paintings.
