INTRODUCTION
Economics is asocial science that
studies how individuals, businesses,
governments, and societies make
choices about allocating resources.
It encompasses a wide range of
topics, including production,
consumption, distribution, and the
behavior of economic agents.

Analyze the impactof government intervention in
economic activities.
Explore the concepts of opportunity cost and trade-offs.
Examine the different types of economic systems.
Scarcity
The basic economicproblem
that arises because resources
are limited while human wants
are unlimited. Scarcity forces
individuals and societies to
make choices about how to
allocate resources effectively.
7.
Opportunity
Cost
The value ofthe next best
alternative that is forgone when
a choice is made. For example, if
a student chooses to spend time
studying instead of working a
part-time job, the opportunity
cost is the income they could
have earned during that time.
8.
Market Equilibrium
The pointat which the quantity
of a good or service demanded
by consumers equals the
quantity supplied by producers.
At this point, the market is said
to be in balance.
9.
Elasticity
A measure ofhow much the
quantity demanded or supplied
of a good responds to changes in
price. Goods can be elastic
(sensitive to price changes) or
inelastic (not sensitive to price
changes).
Supply
Supply refers tothe quantity of a good or
service that producers are willing and able
to sell at various prices. The law of supply
states that, all else being equal, an
increase in price results in an increase in
quantity supplied. This relationship can be
illustrated with a supply curve, which
typically slopes upward from left to right.
13.
Demand
A measure ofhow much the
quantity demanded or supplied
of a good responds to changes in
price. Goods can be elastic
(sensitive to price changes) or
inelastic (not sensitive to price
changes).
14.
Market Equilibrium
Market equilibriumoccurs when
the quantity supplied equals the
quantity demanded. At this point,
the market price stabilizes, and
there is no tendency for it to
change unless an external factor
affects supply or demand.
15.
Shifts in Supply
andDemand
Factors such as consumer
preferences, income levels, and
the prices of related goods can
cause shifts in the demand curve.
Similarly, changes in production
costs, technology, and the
number of suppliers can shift the
supply curve.
17.
Price Controls
These includeprice ceilings
(maximum prices) and price
floors (minimum prices)
that can lead to shortages
or surpluses.
18.
Taxes and Subsidies
Taxescan discourage
consumption of certain
goods, while subsidies
can encourage
production or
consumption.
Opportunity Cost andTrade-offs
Every economic decision involves
trade-offs, as choosing one option
typically means giving up another.
Understanding opportunity cost is
crucial for making informed
decisions.
Traditional Economy
An economythat relies
on customs and
traditions to make
economic decisions.
Production methods are
often passed down
through generations.
23.
Command Economy
An economywhere the
government makes all
economic decisions,
including what to produce,
how to produce it, and for
whom to produce.
24.
Market Economy
An economywhere
decisions are made based
on supply and demand,
with minimal government
intervention. Prices are
determined by the market.
25.
Mixed Economy
An economythat
incorporates elements of
both market and
command economies.
Both private and public
sectors play a role in
economic decision-making.
