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.

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
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
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
GOALS OF A FIRM

 Market share
 Customer satisfaction
 ROI
 Technological advancement
 Long run survival
 Entry prevention & risk avoidance
 Social/Environmental concerns

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

     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.
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.
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
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%
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

 DETERMINANTS OF DEMAND

 PRICE
 INCOME
 PRICES OF RELATED GOODS i.e. SUBSTITUTE
  AND COMPLEMENTARY GOODS
 ADVERTISING AND SALES PROMOTION
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
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
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.
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
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’.
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.
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
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
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.

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:
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.
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.

    THE LAW OFDEMAND  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.

    DEMAND CURVE  TheLaw 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’.

    DEMAND FUNCTION  Theprice-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.

    MARKET RESEARCH ANDLAW 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:

    MARKET RESEARCH ANDLAW 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.

    MARKET RESEARCH ANDLAW 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.
