Introducing Economics



                        1
Definition of Economics
The study of how society
chooses to allocate its
scarce resources to the
production of goods and
services in order to satisfy
unlimited wants

What is
  Ceteris Paribus?
A Latin phrase that means
that while certain variables
can change, “all other
things remain unchanged”

                               4
BASIC CONCEPTS:
•   Scarcity - the fundamental
economic problem that human      wants
exceed the availability of  time,
goods, and resources.
•    Choice – Because individuals
and society can never have everything
they desire, they therefore are forced
to make choices
•    Opportunity cost – the second best
     alternative foregone for a chosen
option.                                   5
Factors of Production
1. Land Resource - any natural resource
   provided by nature
2. Labour - The mental and physical capacity
   of workers to produce goods and services
3. Capital - The physical plants, machinery,
   and equipment used to produce other
   goods
   (Financial capital - The money used to
   purchase capital)
4. Entrepreneurs - The creative ability of
   individuals to seek profits by combining
   resources to produce innovative products 6

Graph
Graphs provide a means to clearly
show economic relationships in two-
dimensional space. Economic analysis
is often concerned with two variables
confined to the upper right-hand
(northeast) quadrant of the coordinate
number system.

                                     8
A shift in a curve occurs only
when the ceteris paribus
assumption is relaxed and a third
variable not on either axis of the
graph is allowed to change



                                      9
Marginal Analysis
- An examination of the
  effects of additions to or
  subtractions from a
  current situation

                           10
Production Possibilities
        Curve:
- A curve that shows the
  maximum combinations of
  two outputs that an
  economy can produce,
  given its available
  resources and technology
                         11
Technology:
The body of knowledge
 and skills applied to
 how goods are
 produced

Production Possibilities Curve
• A production possibilities curve
illustrates an economy’s capacity to
produce goods, subject to the constraint
of scarcity.
• The production possibilities curve is a
graph of the maximum possible
combinations of two outputs that can
be produced in a given period of time,
subject to three conditions:
                                      14
(1) All resources are fully
employed
    (2) The resource base is not
allowed to vary during the time
period.
    (3) Technology, which is the
body of knowledge applied to the
production of goods, remains
constant.
                                   15
Points “inside”, “along” and
 “outside” the PPC
• Inefficient production occurs at any
point inside the production possibilities
curve.
• All points along the curve are efficient
points because each point represents a
maximum output possibility.
• All points outside the curve are
unattainable due to scarcity of resources.
                                        16
The shape of PPC
• PPC is usually concave to the origin
because of the law of increasing opportunity
costs that states that the opportunity cost
increases as the production of an output
expands.
•The explanation for the law of increasing
opportunity costs is that the suitability of
resources declines sharply as greater
amounts are transferred from producing one
output to producing another output.
                                         17
Economic Growth
• The ability of an economy to
  produce greater levels of output,
  represented by an outward shift of
  its production possibilities curve as
  a result of an increase in resources
  or an advance in technology

Basic Economic Problems
- The fundamental economic questions facing any
economy are What, How, and For Whom to
produce goods.
- The WHAT question asks exactly which goods
are to be produced and in what quantities.
- The HOW question requires society to decide the
resource mix used to produce goods.
-The FOR WHOM problem concerns the division
of output among society’s citizens.
