question
partial list of some goods:
answer
a computer, a car, a watch, a television set, friendship, and love.
question
for something to be a good (whether tangible or intangible),
answer
it only has to give someone utility or satisfaction.
question
It takes ________ to produce goods
answer
resources
question
Sometimes resources are referred to as
answer
inputs or factors of production
question
economists divide resources into four broad categories:
answer
land, labor, capital, and entrepreneurship
question
Define land
answer
All natural resources, such as minerals, forests, water, and unimproved land. For example, oil, wood, and animals fall into this category.
question
Define labor
answer
The physical and mental talents that people contribute to the production process. For example, a person building a house is using his or her own labor.
question
Define capital
answer
Produced goods that can be used as inputs for further production. Factories, machinery, tools, computers, and buildings are examples of capital. One country might have more capital than another; that is, it has more factories, machinery, tools, and the like.
question
Examples capital
answer
Factories, machinery, tools, computers, and buildings are examples of capital. One country might have more capital than another; that is, it has more factories, machinery, tools, and the like.
question
Define entrepreneurship
answer
The talent that some people have for organizing the resources of land, labor, and capital to produce goods. Seeking new business opportunities. Develop new ways of doing things.
question
Scarcity is
answer
the condition in which our wants (for goods) are greater than the limited resources (land, labor, capital, and entrepreneurship) available to satisfy those wants.
question
Other words for scarcity
answer
we want goods, but not enough resources are available to provide us with all the goods we want.
question
Our wants (for goods) are ______, but our resources (which we need to produce the goods) are _____.
answer
are infinite; are finite
question
Scarcity is the result of
answer
our infinite wants hitting up against finite resources.
question
Economics
answer
the science of how individuals and societies deal with the fact that wants are greater than the limited resources available to satisfy those wants.
question
Economics is the s_____________
answer
science of scarcity
question
scarcity is the condition in which
answer
in which our wants for goods and services are greater than the resources available to satisfy those wants.
question
Scarcity can exist at the same time
answer
same time that wealth does.
question
Effects of Scarcity
answer
-the need to make choices, -the need for a rationing device -competition
question
A rationing device is
answer
a means of deciding who gets what of available resources and goods.
question
An example of a rationing device would be
answer
the dollar price
question
True or false? Scarcity is the condition of finite resources. Explain your answer.
answer
It takes two things for scarcity to exist: finite resources and infinite wants. If people's wants were equal to or less than the finite resources available to satisfy their wants, scarcity would not exist. Scarcity exists only because people's wants are greater than the resources available to satisfy their wants. Scarcity is the condition resulting from infinite wants clashing with finite resources.
question
How does competition arise out of scarcity?
answer
Because of scarcity, there is a need for a rationing device. People will compete for the rationing device. For example, if dollar price is the rationing device, people will compete for dollars.
question
How does choice arise out of scarcity?
answer
Because our unlimited wants are greater than our limited resources—that is, because scarcity exists—some wants must go unsatisfied. We must choose which wants we will satisfy and which we will not.
question
Opportunity costs
answer
The most highly valued opportunity or alternative forfeited when a choice is made
question
Economists believe that a change in opportunity cost can change
answer
a person's behavior
question
The higher the opportunity cost of doing something,
answer
the less likely it will be done
question
the word marginal is a synonym for
answer
for additional.
question
Marginal benefits
answer
additional benefits. The benefits connected to consuming an additional unit of a good or undertaking one more unit of an activity.
question
Marginal costs
answer
Additional costs. The costs connected to consuming an additional unit of a good or undertaking one more unit of an activity.
question
Decisions at the margin
answer
Decision making characterized by weighing the additional (marginal) benefits of a change against the additional(marginal) costs of a change with respect to current conditions.
question
the right amount of anything is
answer
is the optimal or efficient amount
question
the optimal or efficient amount
answer
the amount for which the marginal benefits equal the marginal costs.
question
you have achieved efficiency when
answer
when the marginal benefits equal the marginal costs.
question
efficiency, which is consistent with , is also consistent with
answer
maximizing net benefits.
question
An incentive is
answer
something that encourages or motivates a person to undertake an action.
question
Unintended effects
answer
A positive or negative outcome that was not anticipated
question
Exchange/Trade
answer
The process of giving up one thing for another
question
Economics is sometimes called the
answer
"science of exchange" because so much that is discussed in economics has to do with exchange.
question
Give an example to illustrate how a change in opportunity cost can affect behavior.
answer
Every time a student is late to history class, the instructor subtracts one-tenth of a point from the person's final grade. Economists predict that, if the instructor raises the opportunity cost of being late to class by subtracting one point from the final grade, then fewer students will be late to class. In sum, the higher the opportunity cost is of being late to class, the less likely it is that people will be late to class.
question
Studying has both costs and benefits. If you continue to study (say, for a test) for as long as the marginal benefits of studying are greater than the marginal costs, and you stop studying when the two are equal, will your action be consistent with having maximized the net benefits of studying? Explain your answer.
answer
Yes.
question
You stay up an additional hour to study for a test. The intended effect is to raise your test grade. What might be an unintended effect of staying up another hour to study?
answer
You might feel sleepy the next day, you might be less alert while driving, and so on.
question
When it comes to economic problems, the national debate usually proceeds along these lines:
answer
First, the problem is identified and defined or described. Second, individuals attempt to identify the cause of the problem. Third, individuals propose solutions to the problem.
question
The term ceteris paribus means
answer
"all other things constant" or "nothing else changes."
question
Ceteris paribus is
answer
an assumption used to examine the effect of one influence on an outcome while holding all other influences constant.
question
a theory is
answer
an abstract representation of the world designed with the intent to better understand the world.
question
abstract means that you
answer
omit certain variables or factors when you try to explain or understand something.
question
Abstract is the process
answer
(used in building a theory) of focusing on a limited number of variables to explain or predict an event.
question
What is the purpose of building a theory?
answer
The purpose of building a theory is to explain something that is not obvious. For example, the cause of changes in the unemployment rate is not obvious, so the economist would build a theory to explain changes in the unemployment rate.
question
How might a theory of the economy differ from a description of it?
answer
A theory of the economy seeks to explain why certain things in the economy happen. For example, a theory of the economy might try to explain why prices rise or why output falls. A description of the economy is simply a statement of what exists in the economy. For example, we could say that the economy is growing or contracting or that more jobs are available this month than last month. A description doesn't answer questions; it simply tells us what is. A theory tries to answer a "why" question, such as, "Why are more jobs available this month than last month?"
question
Why is it important to test a theory? Why not simply accept a theory if it sounds right?
answer
If you do not test a theory, you will never know whether you have accomplished your objective in building the theory in the first place. In other words, you will not know whether you have explained something accurately. We do not simply accept a theory if it sounds right, because what sounds right may actually be wrong. For example, no doubt during the time of Columbus the theory that the earth was flat sounded right to many people and the theory that the earth was round sounded ridiculous. The right-sounding theory turned out to be wrong, though, and the ridiculous-sounding theory turned out to be right.
question
Your economics instructor says, "If the price of going to the movies goes down, people will go to the movies more often." A student in class says, "Not if the quality of the movies goes down." Who is right, the economics instructor or the student?
answer
Unless stated otherwise, when economics instructors identify the relationship between two variables, they implicitly make the ceteris paribus assumption. In other words, the instructor is really saying, "If the price of going to the movies goes down, people will go to the movies more often—assuming that nothing else changes, such as the quality of movies, and so on." Instructors don't always state "ceteris paribus," because if they did, they would be using the term every minute of a lecture. So the instructor is right, although a student who is new to economics might not know what the instructor is assuming but not saying.
question
