A social science studies human society and the relationships with people and organizations over
time. It is difficult to isolate variables because people and societies are so complex. Economics
is a social science because it studies how people interact to produce and allocate resources.

3) Identify the three fundamental economic questions.
What to produce? How to produce? For whom to produce?
                                                                                    Name: ______________________

In a market economy, production is decided by supply and demand, while in a command economy,

5) Explain the role of ceteris paribus in economic models.
Ceteris paribus means to “hold all other things equal”. Since economics deals with individuals, it
is hard to isolate factors and causes. We use the ceteris paribus assumption to create simpler
and more functional economic models.

Macroeconomics is a study of a whole economic system, such as a country. In other words,

want the next unit. When the marginal benefit is less than the marginal cost, we don’t want the
next unit.

8) Why did the chicken cross the road? Explain your answer using economic reasoning.
Lots of variety in answers, so long as there is appropriate terminology use.

The chicken crossed the road to maximize his own utility, or happiness.

The chicken crossed the road because the opportunity cost, the next best choice he had, was too

The chicken crossed the road because the marginal benefit of crossing the road outweighed
(=was more than) the marginal cost.

9) What is a production possibilities curve (PPC)?
A production possibilities curve is an economic model showing the possible use of resources
between two products or sectors.

A PPC is a model showing the possible output in two sectors or products using available

10) Draw a production possibilities curve (PPC) for capital and consumer goods. Identify points at which production is
inefficient, where production is efficient, and where it is not possible at this time.
                                                                                 Name: ______________________
11) Define economic growth. Illustrate this on your PPC, and explain why this shows economic growth.
Economic growth is an increase in production.

12) Explain the difference between economic growth and economic development.
Economic growth is an increase in production, while economic development is growth which
leads to a higher standard of living for the whole population. (Economic growth is quantitative,
while economic development is qualitative.)

13) What is sustainable development? In your answer, try to give some specific examples.
Sustainable development is when growth leads to a higher standard of living for the population,
but does not sacrifice the needs of future generations. For example, sustainable development in
Brazil would require some protection of the rainforest for future generations.

Sustainable development is development which does protects the interests of future generations.
For example, development which doesn’t use up all of a non-renewable resource, such as lumber,
minerals, oil, or water. For example, development which does not create huge environmental
problems for future generations.

14) What is opportunity cost? Give a specific example in your answer.
Opportunity cost if the cost of the next best option/choice. For example, when I came to school
today, my opportunity cost was time spent cleaning my home. For example, when I chose to go to
soccer practice, my opportunity cost was the time I could have spent studying. For example, the
opportunity cost of my new $200 iPod was 10 new CDs.

15) Define the four factors of production and give a specific example of each.

    1.   Land – “unaltered gifts of nature” – grain, milk, land(on which to put a factory)
    2.   Labor – the work done by people – plumber, teacher, factory worker
    3.   Capital – a man-made good used to produce something else – factory, assembly machine
    4.   Entrepreneurship (Enterprise) – person who brings the other three factors together (takes
         the the risk, gets the reward) – Bill Gates, Martha Stewart.
