Enlightenment

of study
 Macroeconomics – branch of economics that
deals with economic theory and the economic
decisions of large bodies like the government.
 Theories of Economics
 Countries and their governments
 Trade between countries
 Microeconomics – branch of economics that
deals with behavior and decisions of smaller
unit like individuals and businesses.
 Families, businesses, and communities
 Domestic economies

6. Microeconomics: Studies the behaviors of
INDIVIDUALS within an economy: Consumers and
producers in particular markets.
Examples of microeconomic topics:
•The Automobile market in Switzerland or Japan,
•The market for movie tickets in India,
•The market for airline tickets between the US and
Europe,
•The market for vacations to Spain,
•The market for international school teachers.

7. Macroeconomics: Studies the total effect on a
nation's people of all the economic activity within that
nation. The four main concerns of macroeconomics
are:
1.total output of a nation,
2.the average price level of a nation,
3.the level of employment (or unemployment) in the
nation and
4.distribution of income in the nation
Examples of macroeconomic topics:
•Unemployment in Pakistan, inflation in Sri Lanka,
economic growth in China, the gap between the rich
and the poor in North & South America

Microeconomics vs. Macroeconomics
The two main units in your economics course can be broken
down into many smaller topics. Some of them are identified
below.

9. ““The Economic Problem”The Economic Problem”
 Scarcity… What is it?
 Limited resources but unlimited wants
 Scarcity arises when something is both limited in
quantity yet desired
 Unlimited wants VS Limited Resources
 You can’t buy 10 candy bars if the store only has
5 candy bars to sell.
 Can’t buy 3 burgers if you only have enough
money for 1.

10. Scarcity means…Scarcity means…
We must use things efficiently in order to
maximize the number of goods and services we
can produce.
 Don’t waste…
The Economic Problem (Scarcity)–
 We can’t have everything we want!!
 Because of this… we need to make choices.
 What we want (need) VS what we can give
up (live without)

11. ResourcesResources –– Factors of ProductionFactors of Production
 Natural resources (Land)– “free gifts of nature”
 Land, minerals, oil, forests, air, and timber
 Capital Resources – “manufactured aids to production”
 Tools, machines, equipment, factories
 Things used in producing goods and services and
getting them to consumers.
 Human Resources (Labor)– “mankind’s physical and
mental talent”
 These are the skills people have that are used to
produce goods and services.
 Entrepreneurship – the individual who combines the
factors of production in order to produce goods or
services.
 Risk taker, policy maker, and innovator

14. Parts of the Business CycleParts of the Business Cycle
 Peak (boom)– Highest point in the
economic cycle.
 Economy is at its best and will likely begin to
contract.
 Recession (contraction)– decline in the
economies performance that could lead to
depression.
 Not long term and does not always impact
other economies

15.  Trough (depression)– A sustained
economic downturn that impacts our
economy and that of other countries.
 Lowest economic point
 Recovery (expansion)- Economic activity
begins to pick up and depression begins
to end.
 Economic growth occurs

16. 3 Basic Economic Questions3 Basic Economic Questions
 What to produce?
 With limited resources, deciding what is
needed the most is often a factor in
determining what will be produced. What is
the need or want of this product?
 What is the point of making a product that no
one is going to buy. Businesses need to
make money…so they choose products that
people want.

17. 3 Basic Questions Cont…3 Basic Questions Cont…
 How should it be produced?
 Technology, labor, capital, ect.
 getting the lowest cost to make the product.
 Are we going to make the product from
scratch or will a machine be making the
product.
 What will each option cost?
 Will having new technology allow us to lower
our expenses?

18. 3 Basic Questions Cont…3 Basic Questions Cont…
 Whom should it be produced for?
 Who is going to use this product?
 Did Apple market the ipod to the large population
of elderly people in the U.S. or the youth? Why?
 Most goods and services are distributed to
individuals through a price system.
 If you want it and can afford to buy it…you will.
 Products can also be distributed through other
means; force, first come, lottery, majority, ect.

19. InflationInflation
 The rate at which the general level of prices for
goods and services is rising, and, subsequently,
purchasing power is falling.
 As inflation rises, every dollar will buy a
smaller percentage of a good. For example, if
the inflation rate is 2%, then a $1 pack of gum
will cost $1.02 in a year.

20. Economic Growth vs. Economic Development
Two of the key areas of study in economics are those of growth
and development. Sometimes these concepts are thought of as
the same, but they are not.
Economic Growth: This refers to the increase in the total output
of goods and services by a nation over time.
•It is also sometimes defined as an increase in household
income over time.
•It is purely a monetary measure of the increases in the material
well being of a nation.
Economic Development: This refers to the improvement in
peoples’ standard of living over time.
•Measured by improvements in health, education, equality, life
expectancy and so on
•Incorporate income as well, but is a much broader measure
than growth
