Managerial Purpose of Demand AnalysisImportant technique for sales fore-casting with a sound base and greater accuracy.Provides a guideline for demand manipulation through advertising and sales promotion programmes.Directs product planning and product improvement.Useful in determining the sales quota and performance appraisal of personnel in sales department.Serves as an anchor for the pricing policy.Indicates the size of market for given products & the market share of the concerned firm.Reflects the scope of business expansion and competitive position of the firm in market trend

Definition of DemandA schedule of the quantities of a good that buyers are willing and able to purchase at each possible price during a period of time, all other things held constantDemand can also be perceived as a schedule of the maximum prices buyers are willing and able to pay for each unit of a good.Demand for product implies:a) Desires to acquire it,b) Ability to pay for it, andc) willingness to pay for itThus demand for a product refers to the amount of it which will be bought per unit of time at a particular price.

Three facts of Demand Demand is an effective desire backed by ability & willingness to pay. Or we can say want backed by money.Demand is always related to price & timeThe demand may be viewed Ex-ante or Ex-post.Ex-ante demand / intended demand/ potential demandex-post demand / already purchased or the actual amount paid.

Demand Function and Demand DeterminantsDemand function is a comprehensive formulation which specifies the factors that influence the demand for the product. For example,

Dx = f (Px, Ps, Pc, Yd, W, A, E, T, U)Here Dx, stands for demand for item x (say, a car)Px, its own price (of the car)Ps, the price of its substitutes (other brands/models)Pc, the price of its complements (like petrol)Yd, the Disposable income (the income left after direct taxes or budget of the purchaser/consumer)W, the wealth of the purchaserA, the advertisement for the product (car)E, the price expectation of the userT, taste & preferences of userU, all other factors like Climate & weather condition, customs & tradition, habits .

Law of demandSuppose you want to buy mangoes. at Rs.100 per dozen you buy 6 dozens. If the price of mangoes increase to 200/- then how much will you buy? Definitely less quantity of goods. What kind of relationship is there between the price and quantity demanded?There is inverse relation.Here we consider only two factors i.e. price and quantity demanded.

Law of demandThe law of demand states that Ceteris paribus (other things remaining the same), higher the price, lower the demand and vice versa. The law is stated primarily in terms of the price and quantity relationship. The quantity demanded is inversely related to its price.

Assumptions-

All the other factors which determine are assumed to be constant. Which are those factors?Income of the consumer is constant.There is no change in the availability and the price of the related commodities (i.e. complimentary and substitutes)There are no expectations of the consumers about changes in the future price and income.Consumers taste and preferences remain the same.There is no change in the population and its structure.

Demand Function and Demand scheduleBy assuming the non price determinants of the Demand function we reduce the function to Qd = f (Px) Or Dx = f(Px)In the slopeintercept from, the demand curve which may be stated asDx = + Px, where is the intercept term and the slope which is negative because of inverse relationship between Dx and Px.Suppose, = (-) 0.5, and = 10Then the demand function is : D=10-0.5P

Demand schedule Its a tabular representation of the price and the quantity demanded. It tells us the relation between the price of the product and the quantity demandedTwo types of demand schedule1. Individual demand schedule2. Market demand schedule

A change in price results in a movement along a fixed demand curve. This is called as a change in quantity demanded. A change in any other variable that influences quantity demanded produces a shift in the demand curve or a change in demand. Shift in Demand vs Change in Quantity Demanded

Factors that can shift a demand curveChange in consumer incomes: an increase (decrease) in income shifts the demand curve to the right (left). Change in wealth of the consumer: To maintain more electrical equipments a household demands more electricity.Population change: an increase (decrease) in population shifts the demand curve to the right (left). Consumer Preferences: if preference for a particular good increases (decreases), the demand curve will shift to the right (left).

Factors that can shift a demand curveConsumer Preferences: if preference for a particular good increases (decreases), the demand curve will shift to the right (left). Prices of Related Goods: Substitutes: goods that can be consumed in place of one another. If the price of a substitute increases (decreases), the demand curve for the original good will shift to the right (left). Example: Pepsi and Coke. Complements: goods that are normally consumed together, i.e. Television sets and cable connections. If the price of a complement increases (decreases), the demand curve for the original good will shift to the left (right).

Definition of Supply By supply we mean various quantities of a commodity which producers will offer for sale at a particular time at various corresponding prices.In simple words, supply ( like demand ) refers to the quantity of commodity offered for sale at some price during a given period of time.

FACTORS INFLUENCING SUPPLYThe price of the productCosts of productionTechnologyThe number of suppliers in the marketSeasonsThe attractiveness of other marketsMeans of transportation and communication.Taxation Policy.Future expectations of rise in prices.

Important determinants of supply supply function : ..Sx = f (Px,F,T,G,N )Sx refers to Supply of a commodity (say X) Px price of the commodity,F prices of the factors of production T technical know-how" and G Government Poilicies regarding Taxes & Subsidy. N Other factors like the number of firms.

Supply Function : Each of the factors influences supply in a different' way. To isolate the effect of other factors we take these other factors as constant while considering the relationship between supply and one of the above variables.Sx = f (Px)Exactly

Qs = c + dP

Law of supply explains the relationship between price of a commodity and its quantity supplied. Price and supply are directly related. A rise in price induces producers to supply more quantity or the commodity and a fall Prices, makes them reduce the supply. The higher is the price of the commodity the larger is the profit that can be earned, and, thus the greater is the incentive to the producer' to produce more of the commodity and offer It in the Market.

Law of Supply

Supply curveBased on the assumption that there is direct relationship between price and supply. i.e. with increase in price, the quantity supplied is increasing and with decrease in price the quantity supplied is decreasing.supply curve exhibits the information graphically instead of arithmetically. It shows the relationship between price and the quantity supplied. Quantity suppliedPriceSS14O101218103018cba

Shift/Change in SupplyA shift in supply curve occurs when the producers are willing to offer more or less of a commodity because of reasons other than the price of the commodity. It is also known as the increase or decrease in supply.SS101830Quantity suppliedPrice18141210O7S1S1

Factors that Shift the Supply CurveChange in cost of inputs: an increase (decrease) in inputs costs shifts the supply curve to the left (right). Increase in technology: an increase in technological progress shifts the supply curve to the right. Change in size of the industry: if size of an industry grows (shrinks) the supply curve will shift to the right (left).

The demand and supply functions for a product areQd = 4200 100PQs = 3000 + 20PIf the government imposes a specific tax of Rs.10 per unit, What would be the new equilibrium price of the product?

SolutionWhen tax is imposed, the supply function becomes Qs = 3000 + 20(P 10)Thus, at equilibrium, 3000 + 20 (P 10) = 4200 100P4200 3000 + 200 = 120POr, P = 1400/120 = 11.67.

Case: Maruti Suzuki shares slip over 1% on falling demand concernThe company has shut the third shift at its diesel engine plant at Manesar, which has an annual capacity of 3,00,000 units. The prolonged slump in the automobile market has resulted in dip in sales coupled with increase in prices of diesel which has resulted in tapering off demand for diesel vehicles. MSI had reported a 12.6 per cent decline in total sales in June at 84,455 units. During the month, its domestic sales declined 7.8 per cent at 77,002 units.
