Lack of resources. Emphasis
that there are not enough
resources to meet all people's
wants. As a result choices
has to be made.
Waste is expensive therefore they
have to use resources efficiently.
Opportunity cost
"The next best alternative
forgone when an economic
decision is made.
you have 100$ and you want
to buy a bag (98$) and a dress
(95$).You can't buy both so if
you buy the bag the dress will
be the opportunity cost.

Demand
Definition
Is the willingness and ability of
consumers to buy a quantity of a good
or service at a certain price. (in a given time period
Markets
Define as a process or institute in which
producers and consumers interact in order to
sell or buy a good or service.
The Law of Demand
Definition
As the price of a product falls, the quantity
demand of a product increases and when the
price of a product increases, the quantity
demanded falls.
Demand Schedule
Is a table giving the quantities
demanded at a range of
prices.
Demand Curves
It plots the information on a graph with the price on the Y-axis
and the quantity demanded on the X-axis.
A change in the price of the product will lead to a change in the quantity
demanded of the product. There is a movement along the demand curve.
Downward Slope
The Increase in Demand is due to:
Income
When the price of a good falls, people
will have have an increase in their
real-life income. Likely to buy more.
Substitution Effect
When the price of a product falls the product
will become more attractive to people than
other similar products whose prices have stayed the
same.
Non Price Determinant of Demand:
Income
Inferior Goods
As income rises, demand for the
product will fall as the consumers
starts to buy higher priced substitutes
instead.
Public Transport
Butter and Margarine
Rice and bread.
As income rises, the demand curve will
shift to the left.
own brand products at the
supermarket
2 types of products to consider when looking at how
a change in income affects the demand for a
product.
Normal Goods
As income rises, the demand for the
product will also rise.
As income rises, the
demand curve for normal
goods will shift -----> to the
right.
Size of shift depends on the good.
Leads to a shift in the demand curve
either to the right or to the left.
Make the ceteris paribus assumption
The price of other goods
Substitutes
If products are substitutes for each other, then a change in
the price of one of the product will lead to change in the
demand for the other product.
Coca Cola and Pepsi
Chicken and Beef
If there is a fall in the price of chicken, there
will be an increase in the quantity demanded
of chicken and a fall in the demand for beef.
This could lead to a
movement along the
demand curve for chicken.
And a shift to the
left of the demand
curve for beef.
Complements
Products purchased together.
Cars and petrol
DVD player and DVD's
Tennis racket and tennis ball
If the price of one product change it will lead to a change in
demand for for the other products.
If there is a fall in the price of DVD players, then there
will be an increase in the quantity demanded of DVD
player and also an increase in the demand for DVD's,
which are complements.
Unrelated Goods
Products that have nothing in common
A change in the price of one product
will have no effect upon the demand
for the other good
An increase in the price of rice will have no
impact upon the demand for clothes
Tastes and Preferences
Firms tries to attempt to influence tastes by marketing, so
that they can shift the demand curve for their product to the
right
Other Factors
The Size of the Population
pop size increases = demand
for most products will increase.
Shift to the right
Age structure of the population
Ageing pop
Demand more for walking sticks and nursing homes.
Young pop
Demand more for schools, teachers, clothes shops.
Supply
Definition
The willingness and ability of a
producer to produce a quantity
of goods or service at a certain
price (in given time period).
The law of Supply.
States as the price of
a product rise, the
quantity supplied will
usually increase,
ceteris paribus.
The curve will normally
slope upwards.
Can be illustrated by
schedule or a supply
curve
The Non-Price Determinant of Supply:
2.The Price of Other Goods.
Producers often have a
choice as to what they
are going to supply.
example: A producer of roller skates
may be able to produce stake boards
with minimal change in facilities.
If the price of the skateboards
rise, because there is more
demand for them, then it may be
that the producers will be
attracted by higher prices and
come to supply more
skateboards and fewer roller
skates.
There is a movement along the supply
curve for skateboards.
There will also be a fall in
supply for roller skates at all
prices
And the supply will shift to the left , even though
the price has not changed there is a fall in supply.
1. Cost of
Factors of
Production.
An increase price in wages
Will lead to a
fewer supply at all prices
It will shift the supply curve
to the left.
3. State Of Technology.
Improvements in tech
will increase in supply.
Improves productivity.
Productivity- os the amount
of output per unit of input.
Lead to a shift to the right.
4. Government Intervention.
Inderect Taxes
Taxes on goods and services that are added to the price of a product.
Increase in indirect tax will lead to increase the
cost of production.
Shift the supply curve to move upwards by the amount of the indirect tax.
Governments inverse in the
markets in ways that alter the
supply.
Regulations
Applying a rules and regulations to protect
consumers or the workers.
Extra cost to the firm
eg. cigarettes and alcohol
Supply Shocks
normal events that disrupt the supply of goods or services
Positive
Shift to the right.
discover minerals in soil
Negative.
Shift to the left
Natural disasters
Man-made environmental disaster
Conflicts such as wars
Subsidies
The government pays producer to make more of the good.
Reduces the cost of production
Shif supply curve to move downwards by the amount of subsidy.
More will be supplied
Production Possibilities
Curves/Production
Possibilities Frontier.
1. PPC shows the maximum
combinations of goods and
services that can be produced by
an economy in a given time
period.
2. Shows that there is a limit to
what a country can produce.
Scarcity of economic resources
limits output to points on or below
the PPC
Shifts
Left
1. Shows a decrease in its
productivity capacity.
Caused by:
War and natural disasters.
Right
1. Shows a country's
ability to produce more
goods and services.
Caused by:
Improvements in the
quality and quantity of
the factors of production.
