CHAPTER 1: ECONOMICS – THE CORE ISSUES
OPPORTUNITY COST
SCARCITY
PRODUCTION POSSIBILITIES
WHAT / HOW / FOR WHOM
MICRO / MACRO
OPPORTUNITY COST
DEFINITION: The most desired goods or services that
are foregone in order to obtain something else. Opportunity cost is
the “NEXT BEST ALTERNATIVE” (what will be given up when we are
confronted with a choice). MONEY COST or PRICE is not
the same as the opportunity cost, it is only a part of opportunity
cost.
- For the INDIVIDUAL opportunity costs arise from
scarcity of time or income.
- For SOCIETY the problem is scarcity of resources; what we forego
when we have to shift resources away from something to the production
of something else. Our desire for goods is limitless but we have
limited resources to produce them. To produce more of one thing,
society must shift resources away from producing something else.
QUESTION:
-
You have an opportunity cost of being in this class.
Instead of sitting in front of your computer right now, what could you
be doing rather than studying today? (Time with family, money income
from a job, a chance to go to the movies with your friends, sleeping,
attending another class.)
-
What is your “next best alternative” to being here?
**Whatever your “next best alternative” is, it
represents the opportunity cost of taking this class. It’s much more
than just lost wages… Economics is the study of choice
under conditions of scarcity.
- Or the study of how to best allocate scarce resources among
competing issues.
- We all have scarce time, scarce spending power and scarce resources.
-
Why do you choose a short line at the campus
bookstore?
-
If you work, how do you schedule your work hours over
the course of a given week or over the course of a year? (no work
during class hours or maybe only during summer and holiday breaks). By
making a school/work schedule, you are allocating your scarce time.

SCARCITY: The core problem
of economics
Definition: The fact that available resources
are insufficient to satisfy all desired uses thereof. The U.S., like
any other country, has to deal with the problem of scarcity.
FACTORS OF PRODUCTION
The factors of production are the resource inputs used to produce
goods and services. Every business utilizes various combinations of
the factors of production to produce final goods or services.
There are FOUR basic factors of production:
-
LABOR is the time human beings spend producing goods
and services as well as the skills and abilities we use to produce
goods and services. Both the quantity and quality of human resources
included in “labor” factor.
-
CAPITAL is the long-lasting tools that people use to
produce goods and
services or final goods produced for use in the production of other
goods.
-
Physical Capital includes buildings, machinery and
equipment.
-
Human Capital includes the skills and training that
workers possess.
**Capital is long lasting (overhead projector). A raw
material is consumed in a short period of time – not long lasting
(chalk).
-
LAND is the physical space on which production takes
place, as well as
natural resources found under it or on it: crude oil, water, air,
minerals, iron, coal, lumber, etc.
-
ENTREPRENEURSHIP is the assembling of resources to
produce new or
improved products and technologies. Entrepreneurship determines how
well we use our resources.
LIMITS TO OUTPUT
Anything in the economy comes from some combination of these
resources. Because resources are limited, society must decide how to
ALLOCATE these scarce resources.
- Households have
limited incomes. - Business firms want to make highest
possible profit but they have to pay for their resources so they have
to decide what to produce, how much to produce and how to produce it.
- Government has limited budgets and must choose which goals to
pursue. - Three core issues that must be resolved:
-
WHAT to produce with our limited resources.
-
HOW to produce the goods and services we select.
-
FOR WHOM goods and services are produced; that is, who
should get them.
Scarcity, or the imbalance between our desires and
available resources, forces us to make economic choices.
EXAMPLE:
Ever heard the term “Guns vs. Butter”? Well, the basic idea is
that because our resources are scarce, if we want to produce more
defense (guns), we have to produce fewer consumer goods (butter).
Military spending gobbles up our scarce resources. The 1.4 million men
and women in armed forces not available for other jobs – building
schools, designing clothes, teaching economics, etc. Land, labor,
capital and entrepreneurship dedicated to producing military hardware
is not available to produce civilian goods. This is the guns vs.
butter dilemma.

PRODUCTION POSSIBILITIES
FRONTIER (Figure 1.1, Page 7)
DEFINITION: The alternative combinations of
final goods and services that could be produced in a given time period
with all available resources and technology.

Each point on the production possibilities curve depicts an
alternative mix of output in an economy that only produces two goods.
The production possibilities curve (PPC) illustrates:
-
Scarce resources – There is a limit to the amount we
can produce in a given time period with available resources and
technology.
-
Opportunity costs – We can obtain additional
quantities of any desired good only by reducing the potential
production of another good.
OUTSIDE POSITIONS
Positions outside the PPC are unattainable with current technology and
resources. In order to reach a point outside the curve we must either
have an increase in technology or an increase in available resources.
LAW OF INCREASING OPPORTUNITY COSTS
As we produce more of a good, the opportunity cost of producing more
of that good increases with each additional unit produced. The law of
increasing opportunity costs results in the CONCAVE SHAPE of the PPC
(slope). The PPC becomes steeper as we moved rightward and downward.
As we move from the edges, less has to be given up to get a lot more
of the other good.
-
Why do opportunity costs increase as we produce more
of a good?
Most resources by nature are better suited to some purposes than
others. If we look at the PPC above, if all of our resources are being
used to produce military goods but we begin to produce some
healthcare, first we will shift resources best suited to healthcare
(doctors, nurses, CT scans, etc.). There are some resources that are
better suited to healthcare.
-
Milton Friedman once said: “There is no such thing as
a free lunch.” He meant that even if a lunch is free, society is still
paying an opportunity cost by not producing other things with those
resources.
INSIDE POSITIONS
If we are producing at a point inside the PPC, then is productive
inefficiency (resources are being wasted due to underemployment of
resources, etc.) At points inside the PPC, we have the possibility to
produce more of both goods. We can a point on the PPC without any
opportunity costs.
-
EFFICIENCY – Any point on the curve tells us that we
are getting the maximum output of a good from the resources used in
production.
-
PRODUCTIVE INEFFICIENCY
A firm, an industry or an entire economy is productively inefficient
if it could produce more of at least one good without pulling
resources from the production of any other good. There can only be
productive efficiency if we are producing at maximum output in which
case we can’t produce one more good without giving up another. In
other words, the economy’s actual output less than potential output.
Example: Empty seats on an airline flight. We could be
producing more by carrying more passengers. Full capacity is not being
reached.
-
UNEMPLOYMENT
If there is unemployment, we would be producing at a point inside the
PPC. In 1992 Ten Million Americans were looking for work per week so
we had less output than we could have had. If those people were
employed, our economy could have been producing more goods and
services. In 2001 the U.S. was much closer to full employment.
-
RECESSIONS
A recession is a slowdown in overall economic activity, resulting in
unemployment. Factories shut down so we are not using all of our
available capital or land.
ECONOMIC GROWTH
As we said before, all
output combinations outside the PPC are unattainable with available
resources and technology. Over time, the population increases (more
labor), we build factories and machinery (the stock of available
capital increases), and the quality of labor can increase (education,
training). This will SHIFT the PPC OUTWARD – increasing potential
output. Economic growth is an increase in output (real
GDP) or an expansion of our Production Possibilities.

WHAT / HOW / FOR WHOM
THE “INVISIBLE HAND” OF THE MARKET ECONOMY
Adam Smith said the “invisible hand” determines what gets produced,
how, and for WHOM. The MARKET MECHANISM is the use of
market prices and sales to signal desired outputs (or resource
allocations). The market mechanism answers the WHAT TO PRODUCE
question. The market mechanism can also answer the HOW
and FOR WHOM questions because:
- PRODUCERS will seek to use the lowest-cost method of
producing a good.
- and the HIGHEST BIDDER or individuals who are willing and able to
pay the most for a good tend to get it in a pure market economy.
LAISSEZ FAIRE is the doctrine of “leave it alone”, of
nonintervention by government in the market mechanism.
GOVERNMENT INTERVENTION AND COMMAND ECONOMIES
Karl Marx
emphasized how free markets tend to concentrate wealth and power in
the hands of the few, at the expense of the many.
-
As Marx saw it, unfettered markets permit the
capitalists (those who own the machinery and factories) to enrich
themselves while the proletariat (the workers) toil long hours for
subsistence wages.
-
Marx argued that the government not only had to
intervene but had to own all the means of production.
John Maynard Keynes seemed to offer a less drastic
solution.
-
The market, he conceded, was pretty efficient in
organizing production and building better mousetraps.
-
However, individual producers and workers had no
control over the broader economy. He believed the cumulative actions
of so many economic agents could easily tip the economy in the wrong
direction.
-
In Keynes’ view, government should play an active but
no all-inclusive role in managing the economy.
THE DEBATE CONTINUES
-
Conservatives favor Adam Smith’s laissez-faire
approach.
-
Liberals tend to think government interventions are
likely to improve the answers.
-
Countries answer the basic economics questions
differently and their answers change over time.
A MIXED ECONOMY
-
Most economies use a combination of market signals and
government directives to select economic outcomes.
-
A MIXED ECONOMY is one that uses both market signals
and government directives to allocate goods and resources.
MARKET FAILURE
-
When market signals don’t give the best possible
answers to the WHAT, HOW, and FOR WHOM questions, we say that the
market mechanism has failed.
-
A MARKET FAILURE is an imperfection in the market
mechanism that prevents optimal outcomes.
GOVERNMENT FAILURE
-
Government intervention may move us closer to our
economic goals. But government intervention may fail as well.
-
GOVERNMENT FAILURE is government intervention that
fails to improve economic outcomes.
Examples of government failure include:
-
Forcing an industry to clean up its pollution in a manner that is
excessive.
-
Mandating pollution control technologies that are too
expensive or even obsolete.
-
Imposing excessive taxes and transfer payments so that
the total economic pie shrinks making society as a whole worse off.

MICRO VS. MACRO
Economics is divided into two major parts:
- MICROECONOMICS is concerned with the behavior of
individual households, business firms, and governments and how they
interact with each other.
For example: How do firms choose how much to produce or what kind of
products to produce is a microeconomics question.
-
MACROECONOMICS concentrates on behavior of the economy as a whole.
For example: unemployment, interest rates, how government spending
affects economy, GDP or total output of the economy are all
macroeconomic topics.
Macro and Micro are interrelated. Macro (aggregate)
outcomes depend on micro behavior and micro (individual) behavior is
affected by macro outcomes. THE ECONOMY TOMORROW
GOVERNMENT INTERVENTION:
Micro intervention:
Microsoft Antitrust case for suppressing innovation and harming
consumers. Microsoft said the market should decide what computer
products and produced and by whom.
Macro intervention:
The government regulates credit conditions. The Federal Reserve tries
to keep interest rates at the right level by regulating bank behavior
to be consistent with macroeconomic goals.
The benefits
of government intervention are not always clear. There will always be
questions of how much government intervention is necessary.
Questions to Consider:
-
Why are you attending college? (To get a good job in
the future??). Economists describe this behavior as Human Capital
Development.
-
Why do you choose to attend this particular college?
Are you maximizing the amount of learning, social experience, future
income? Do you have constraints: limited family income and wealth,
parental wishes or pressures, limited information (or the costs that
must be paid for more information about different colleges).
-
Usually the attendance on the first day of class and
on exam days is higher than other days. This is because of the
opportunity cost of missing class on these days is higher than other
days. What methods do your professors use to induce attendance? Do
these methods alter students’ choices of how to allocate their scarce
time?
