LOI : 2 The Role of
Supply and Demand
Price Change:
•
Price may change when demand, supply, or both
change.
•
An increase in demand cause prices to increase.
•
An increase in supply cause prices to decrease.
•
If demand and supply both increase but the demand
change is larger, price will increase it will act as if the
only change had been a change in demand.
•
If demand and supply both increase but the supply
change is larger, price will decrease it will act as if the
only change had been a change in supply.
•
Ex. Suppose the government allowed a certain amount
of imported steel to enter the economy. This would cut
down on supply and result in a higher steel price. Also,
if there was a decrease in potato prices it would
suggest an increase in quantity demanded and a
decrease in quantity supplied.
•
What makes prices rise and fall?
•
Do candy makers have a meeting and decide how much
they will charge for their candy? Or does the
government command candy makers to lower their
prices?
•
Who determines the prices of the stuff we buy? It might
seem like mysterious forces are at work, but that's not
the case.
Prices for most goods and services are determined in
markets
by what economists call supply and demand.
Supply and demand
work together
to determine prices.
In fact, supply and demand are among the most
fundamental concepts in economics, so being familiar with
these terms will help you better understand the economic
world around you .

What is an economy?
An economy is a system for
allocating
resources
to meet people's
needs and wants
.
It determines how goods and services are
made and exchanged
. The study of the
economy is called economics and a person
who studies economics is called an
economist
.
The Economy
You've probably heard people talk about "the
economy." When people say this they are usually
referring to the
economy of the country
where they
live. A
good economy
is generally one where there are
lots of good-paying jobs, businesses are making money,
and the overall economy of the
country is growing
. A
bad economy is one where people are losing their jobs,
businesses are shutting down, and the overall
economy isn't growing.

Micro vs. Macro
Economics is often divided up into
macroeconomics and microeconomics.
Microeconomics
studies how
individuals
and
businesses
make
decisions
within the
economy. Examples of microeconomics
include:
•
Why someone chooses to buy one product over another?
•
How the supply and demand of products work
together?
•
What price a company charges for its product?
•
Why different jobs make different amounts of money?
Macroeconomics
looks at a bigger picture
than microeconomics. It looks at the
economy as a whole
and not individuals or
small businesses. Examples of
macroeconomics include:
•
The Gross National Product of a country
•
Unemployment rates
•
Net imports and exports for a country and how this affects jobs
•
The current rate of inflation
Types of Economies
–
Traditional
- A traditional economy is typically based on
bartering, trading, and farming
. The
economy is largely determined by how things have been done in the past with little change.
People in traditional economies tend to do the same jobs as their parents.
–
Market
- A market economy (sometimes called a "
free market
") is one based on
supply and
demand
. Consumers are free to buy whatever product they want. Companies can make
whatever product they want. There is little government intervention allowing the economy to
sort itself out through competition.
–
Command or Planned
- A command economy is one where the
government
closely
controls the
economy
. The government determines what goods are manufactured, the price they will be sold,
and who gets the profits. The government owns many of the major industries.
–
Mixed
- A mixed economy is a
combination
of a
market and a command economy
. Some
industries are owned and controlled by the government, while other industries are allowed to be
determined by the market. Mixed economies vary in how much control and regulations the
government has

Difference between producers
and consumers
Producers
are the people who
create the jobs and the
opportunities and the benefits that
others consume.
Consumers
are
not just people who go out and
shop and buy, but even the jobs
they have were created by
someone else. They are
"
consumers
" of employment. They
consume a job.
Prices in markets are determined by the forces of supply and demand, where changes in one or both factors impact price levels. This concept is essential in economics to comprehend the dynamics of pricing, production, and resource allocation within an economy. The economy revolves around the efficient allocation of resources to meet the needs and wants of people, with economists studying these interactions to understand economic systems better.
