Key Tools & Terms of Economics
ECONOMICS
 It is the social science concern. It is a study of
how people use their scarce resources to
satisfy their unlimited wants.
OR
 The study of the behavior of human beings in
producing, distributing and consuming
material goods and services in a world of
scarce resources.
 It is categorized mainly into two parts such as
Macroeconomics and Microeconomics
Dr. Mazharul Islam
10
Key Tools & Terms of Economics
MICROECONOMICS
• Microeconomics is the study that deals
with an individual industry, firm or
household. For example, talk about the
price of Al Baik. It means it talk about
individual decision maker in specific
markets, especially:
osupply and demand
opricing of output
oproduction process
ocost structure
odistribution of income.
Dr. Mazharul Islam
11
Key Tools & Terms of Economics
MACROECONOMICS:
It is a study that examine the economy as a whole. It
means that it is concerned with the overall
performance of the economy. Such as it does not
discuss about the price of Al Baik but about the
average price of all goods and services produced in
the economy. Especially talk about:
onational output (GDP)
ounemployment
oinflation
ofiscal and monetary policies
otrade and finance among nations
Dr. Mazharul Islam
12
Key Tools & Terms of
Economics
MANAGERIAL ECONOMICS
The use of economic analysis to make business
decisions involving the best use (allocation) of an
organization’s scarce resources.
ECONOMIC PROBLEM
 Basic economic problem is wants are virtually
unlimited while the resources available to satisfy
these wants are scarce.
SCARCITY
 Lack of enough resources to satisfy all the needs and
wants of a specified group of people. Since resources
are scarce, it follows that the goods and services we
produce must also be limited.
Dr. Mazharul Islam
13
Key Tools & Terms of
Economics
CHOICE
 Due to scarcity, we can’t have all that
we want. We must decide what we will
have, and what we must forgo. That is
why we make choices.
 Opportunity cost is the amount (or
subjective value) that must be
sacrificed in choosing one activity
over the next best alternative.
Dr. Mazharul Islam
14
Key Tools & Terms of
Economics
TWO BIG ECONOMIC QUESTIONS
Q1. How do choices end up determining
allocation decisions in scarcity? i.e how
to make three choices below?:
What should be produced?
How should it be produced?
For whom should be produced?
Q2. When do choices made in the pursuit
of self-interest ?
Dr. Mazharul Islam
15
Key Tools & Terms of
Economics
What?
The things that satisfy human wants that
means Goods and services needs to
produce.
– In 2011, Agriculture accounts for 2% of
total
Saudi
Arabian production,
Industry goods for 69.1%, and
Services for 28.9% (Source: Central
Intelligence
Agency
(CIA)
World
Factbook 2012).
Dr. Mazharul Islam
16
Key Tools & Terms of
Economics
How?
Goods and services are produced by using
productive resources that economists call
factors of production.
Factors of production are grouped into four
categories:
 Land
 Labor
 Capital
 Entrepreneurial Ability
Dr. Mazharul Islam
17
Key Tools & Terms of
Economics
LAND
It does not refer only a plots of ground but also
includes all other natural resources such as crude oil,
water, air, and minerals etc.
LABOR
It is not simply the number of human bodies but it
refers to the work time and work effort that people
devote to producing goods and services. It
categorized into two parts– physical and mental (9.56
millions out of 26.53 millions in 2010 where about
80% of the labor force is non-national - Source: CIA
World Factbook 2012).
Dr. Mazharul Islam
18

CAPITAL
In economics the term capital refers to final
goods produced for use in further
production. It also categorized into two
parts. These are:
– Physical capital: factories, machines, tools,
buildings, airports, highways and other
manufactured items employed to produce
goods and services.
– Human capital: consists of the knowledge
and skill people acquire to enhance their
labor productivity.
Dr. Mazharul Islam

Economics
ENTREPRENEURIAL ABILITY
– Special kind of human skill
– Talent required to dream up a new
product or find a better way to produce
an existing one.

customers most likely to purchase.
Dr. Mazharul Islam
22
Key Tools & Terms of
Economics
When is the Pursuit of Self-Interest?
Economics assumes that human behavior
reflects “rational self-interest”. It means that
people always try to make the best choices
they can, given the available information.
Moreover, Individuals try to maximize the
expected benefit achieved with a given cost
or minimize the expected cost of achieving
a given benefit. Peoples allocate their time,
energy, and money to maximize it.
Dr. Mazharul Islam
