The document provides an overview of key economic concepts including microeconomics, macroeconomics, demand analysis, determinants of demand, the law of demand, demand curve, demand schedule, exceptions to the law of demand, individual demand versus market demand, circular flow of economic activity, and discusses how market research has found the law of demand is not always applicable in analyzing consumer behavior. It also outlines basic concepts such as scarcity, opportunity cost, productivity, and profit.
2. WHAT IS ECONOMICS?
• Economics is the study of allocation of
scarce resources among alternate uses.
• Economics is the study of how
individuals and groups make decisions with
limited resources as to best satisfy their
wants, needs and desires.
• Economics is on one side the study of
wealth and on the other and more important
side, a part of the study of man.
4. Macro Economics Micro Economics
Studies the economic Studies the behavior of
system in aggregate an individual decision
making unit like an
individual/household/
Looks at the total
firm
output of a nation and
the way the nation
allocates its resources
of land, labour, capital,
etc. to promote trade
and growth
5. MACRO ECONOMICS RELATES TO ISSUES SUCH
AS
NATIONAL INCOME GOVERNMENT
SAVINGS EXPENDITURE - To
curtail Fiscal Deficit
INVESTMENT
Raise taxes
EMPLOYEMENT Cut spending
TAX COLLECTIONS Borrow
FOREIGN TRADE Print
MONEY SUPPLY Easiest politically
Results in inflation
PRICE LEVEL It is a tax on those holding
money
6. Managerial Economics
Analyses the process
Through which a manager uses economic theories
to address the complex problems of business world
and then, take ‘rational’ decisions
in such a way that
the perceived objectives of the firm may be attained
7. THE MANAGER OF A FIRM FACES THE
FOLLOWING BASIC ISSUES
Choice of product
Choice of inputs
Distribution of the firm’s revenues
Rationing
Maintenance and expansion
8. OBJECTIVES OF A FIRM
Maximization of Profit
Maximization of sales revenue
Maximization of growth rate
Maximization of managers utility function
Making satisfactory rate of profit
9. GOALS OF A FIRM
Market share
Customer satisfaction
ROI
Technological advancement
Long run survival
Entry prevention & risk avoidance
Social/Environmental concerns
10. BASIC ECONOMIC CONCEPTS
1. CHOICES AND DECISIONS
RESOURCES
MONEY
MACHINE
MATERIALS
LABOUR
TIME
SKILL
TECHNOLOGY
CHOICES – ALTERNATE USES
WHETHER TO STUDY FULL TIME MBA OR MCA OR LAW
WHETHER TO KEEP MONEY IN SB OR TD OR INVEST IN BUSINESS OR SHARES
OPPORTUNISTIC COST
11. BASIC ECONOMIC CONCEPTS
2. HUMAN ACTION – PURPOSEFUL BEHAVIOUR
3. SCARCITY
If anything is scarce, it is a subject of economics.
Otherwise, it is not a subject matter of economics.
4. TRADE OFF
Economics is about trade off
If you get one thing, you cannot get another thing. You
have to give up one for the other.
12. BASIC ECONOMIC CONCEPTS
5. INCREMENTAL CONCEPT
While adding a new business/buying new input/adopting new process
6. DISCOUNTING CONCEPT
If a decision affects costs and revenues in the long run, they should be
discounted. A rupee in future is less in value
7. TIME PERSPECTIVE
Short term and long term impact due to decisions say pricing decision
8. MARGINAL CONCEPT
Marginal utility of the product. Marginal utility is derived from the additional unit
consumed.
13. BASIC ECONOMIC CONCEPTS
9. EFFCIENCY AND PRODUCTIVITY
How well resources are used in order to get maximum output.
Productivity means with one of input, how much output you get.
Productivity per worker
Productivity per machine
10. MEANS = RESOURCES = INPUT
TIME, MONEY, LAND, LABOUR, CAPITAL, NATURAL RESOURCES
11. UTILITY
Subjective benefit a particular person gets by using a particular goods
12. GOOD (ECONOMIC GOOD)
14. BASIC ECONOMIC CONCEPTS
13. MODEL
Theoretical abstract representation over relationship between two or more
economic variables.
Out put depends on in put (capital, labour, etc)
Every model has four fundamentals
Theory
Variables
Assumptions
Causation
Example: Inflation
Causation: Increasing money supply (Value of money falls, prices increase)
15. BASIC ECONOMIC CONCEPTS
14. ECONOMIC PROFIT Vs. ACCOUNTING PROFIT
Accounting profit ignores opportunity cost
Economic profit is arrived at after taking into account opportunity cost.
EXAMPLE
An individual sets up a shop in a building owned by him and puts in work by himself. The business makes a profit of Rs. 2 lacs. No rent for his premises
and no salary for his work were paid.
ACCOUNTING PROFIT Rs.2,00,000
LESS NOTIONAL RENT Rs.1,44,000
NOTIONAL SALARY Rs. 96,000
Rs.2,40,000
--------------
ECONOMIC PROFIT/LOSS (-) Rs. 40,000
--------------
POSITIVE ECONOMIC PROFIT = Revenue exceeds all costs including opportunity cost.
For economic purposes, economic profit and not accounting profit has to be used.
Opportunity cost is subjective. Accountants want documents to account.
16. BASIC ECONOMIC CONCEPTS
15. NORMAL PROFIT
Suppose one has invested capital. How much interest he will get
on his investment under competitive condition.
Interest on the capital + risk premium
16. EXCESS PROFIT -- GETTING MORE THAN NORMAL PROFIT
You cannot get excess profit in the long run because competition
will emerge.
Govt. also steps in to prevent excess profit being made by various
measures ,
EXAMPLE: Micro Finance, Financing against gold jewellery.
17. INCREMENTAL CONCEPT EXAMPLE
You want to purchase a machine costing
Rs.10,00,000/-. When you approached a
nationalised bank, they offered to lend to the
extent of 80% of the cost of machine at an
interest rate of 10%. You do not have margin
money of Rs.2,00,000/-. When you approached a
private sector bank, they agreed to lend 90% of
the cost of the machine but @ 12%. What is the
incremental cost in terms of % of interest on the
incremental amount of Rs.1,00,000 borrowed for
one year
18. Working for incremental
financing cost
Financing cost = Loan amount x Interest rate
First case = 8,00,000 x 0.10 = 80,000
Second case = 9,00,000 x 0.12 = 1,08,000
Incremental Financing Cost = 1,08,000 – 80,000
= 28,000
Incremental amt. borrowed= 1,00,000
Incremental Financing cost % = Incremental cost/
Incremental borrowing
28,000/1,00,000 = 0.28 = 28%
19. DISCOUNTING CONCEPT EXAMPLE
You are in a position to invest Rs.1 crore in a project. You
have choice of two projects and have to choose the most
profitable project. Discounting rate/Cost of funds is 15%.
Cash inflow over a 5 year period is as follows:
Year Project A Project B
I 10,00,000 0
II 10,00,000 5,00,000
III 10,00,000 5,00,000
IV 10,00,000 10,00,000
V 10,00,000 32,50,000
Which project you will choose?

Present Value = Cash flow/r to the power of n
21. CIRCULAR FLOW OF ACTIVITY
HOUSEHOLDS OWN AND CONTROL RESOURCES AND SELL
THEM TO BUSINESSES
BUSINESSES USE THE RESOURCES TO MAKE FINISHED
PRODUCTS
BUSINESSES TAKE FINISHED PRODUCTS AND SELL THEM TO
HOUSEHOLDS
GOODS AND SERVICES
HOUSEHOLDS BUSINESSES
RESOURCES
22. CIRCULAR FLOW OF ACTIVITY Continued
HOUSEHOLDS PURCHASE GOODS AND AVAIL
SERVICES RESULTING IN EXPENDITURE –
FLOW OF PAYMENTS TO BUSINESSES FROM
HOUSEHOLDS.
HOUSEHOLDS/INDIVIDUALS WORK FOR
BUSINESSES, RENT THEIR PREMISES TO
BUSINESSES AND INVEST IN BUSINESSES.
ALL THESE ACTIVITIES GENERATE INCOME –
FLOW OF PAYMENTS TO HOUSEHOLDS FROM
BUSINESSES.
THE FLOW OF PAYMENTS IN AN ECONOMY IS
A CIRCULAR FLOW
23. DEMAND ANALYSIS
DETERMINANTS OF DEMAND
PRICE
INCOME
PRICES OF RELATED GOODS i.e. SUBSTITUTE
AND COMPLEMENTARY GOODS
ADVERTISING AND SALES PROMOTION
24. DETERMINANTS OF DEMAND Contd….
POPULATION
AVAILABILITY OF CREDIT
SEASON OF THE YEAR
WEATHER
ONE’S STATUS
GEOGRAPHIC LOCATION OF THE BUYERS
EXPECTED FUTURE TREND IN PRICES
CHANGES IN CONSUMER TASTES
NEEDS AND PREFERENCES
CHANGES IN CONSUMER CREDIT FACILITIES
25. MEANING OF DEMAND
Demand in economics means desire to buy
backed by adequate purchasing power.
Mere desire or wish cannot buy goods. The
demand for goods, therefore, denotes that
someone is able and willing to buy the goods.
Example: Car
26. THE LAW OF DEMAND
The relation of price to sales is known in economics as the
‘Law of Demand’.
The Law of Demand states that “higher the price, lower the
demand and vice versa, other things remaining the same”.
Law of Demand states, ceteris paribus (keeping other
factors constant), there is an inverse relationship between
price and quantity demanded.
In simple terms it means, an increase in price will tend to
reduce the quantity demanded and a fall in price will lead to
an increase in the quantity demanded.
27. DEMAND SCHEDULE
PRICE QUANTITY
DEMANDED
Rs.500 1,000 units
Rs.400 1,200 units
Rs.300 1,500 units
Rs.200 2,000 units
28. DEMAND CURVE
The Law of Demand or the Price-Quantity Relationship is also
portrayed graphically in the form of a chart which is called the
‘Demand Curve’.
It is a convention among economists to portray price-quantity
relationship by representing physical quantity on the horizontal
(X) axis and the price on the vertical (Y) axis.
The Demand Curve slopes downward from left to right indicating
that when price rises, less is demanded and when price falls,
more is demanded. This kind of a slope is also called as ‘negative
slope’.
The demand curve concentrates exclusively on the price-quantity
relationship. The relationship between quantity demanded and
other variables are not shown by the ‘Demand Curve’.
29. DEMAND FUNCTION
The price-quantity relation is also expressed
algebraically in the form of the following
equation:
Q = f(P)
which means that quantity demanded is a
function of price.
30. CHARACTERISTICS OF LAW OF DEMAND
INVERSE RELATIONSHIP
PRICE IS AN INDEPENDENT VARIABLE AND
DEMAND IS A DEPENDANT VARIABLE
OTHER THINGS REMAIN THE SAME
REASONS UNDERLYING THE LAW OF DEMAND
Income Effect
Substitution Effect
31. EXCEPTIONS TO THE LAW OF DEMAND
GIFFEN GOODS
LUXURY OR VEBLEN GOODS - GOODS
PURCHASED FOR THEIR ‘SNOB APPEAL’ or
OSTENTATION. Example: Diamonds, art
work, BMW car
FEAR OF FUTURE CANGE - SPECULATIVE
MARKET
32. INDIVIDUAL DEMAND AND MARKET DEMAND
INDIVIDUAL DEMAND
The quantity demanded by an individual
purchaser at a given price is known as individual
demand.
MARKET DEMAND
The total quantity demanded by all the
purchasers together is known as market
demand.
33. MARKET DEMAND - EXAMPLE
Price Quantity demanded in dozen by Total
per A B C D E

34. MARKET RESEARCH AND LAW OF DEMAND
Law of demand is not the last word on
consumer behavior. Rather, sales executives
have often found the Law of demand
irrelevant for their purposes. Market research
has propounded, on the basis of empirical
investigations, certain propositions and
hypotheses.
Some of them are as follows:
35. MARKET RESEARCH AND LAW OF DEMAND Contd….
The more confidence a person has in price information as a
predictor of quality, the more likely he will be to choose a
high priced rather low priced item.
A person who perceives himself as experienced in
purchasing a product will generally choose a low priced
item, but an inexperienced person will select a high priced
one.
A person who selects a high priced item will (a) believe it is
more difficult to judge product quality and (b) feel that he
has less ability to make accurate quality judgments than
one who chooses a low priced item.
36. MARKET RESEARCH AND LAW OF
DEMAND Contd….
Consumer is not rational always. Consumer behavior
is baffling. Sometimes, low price results in low sales
and when the price is increased, sales increase. The
reason: Higher price was essential if the products
real advantages were ever to be noticed.
Consumer’s purchasing behavior is mostly repetitive.
This is against the formulation advocated in
economic theory that the consumer tries to reach
the optimum in every transaction and every time.
