Market demand analysis is important for businesses to forecast sales, develop marketing strategies, and inform pricing and product decisions. Key factors that influence market demand include:
- Price of the product - Demand is typically higher at lower prices.
- Income levels and wealth distribution in the community - Higher and more evenly distributed incomes lead to greater demand.
- Common habits, tastes, and preferences in the community - Shifts in community preferences impact demand.
- Number of potential buyers in the market and population growth - A larger customer base means larger potential demand.
The document discusses food production and population growth in Bangladesh between 1972 and 2014. It notes that while the population grew 2.3 times during this period, food production increased 3.5 times even though available agricultural land decreased by 15%. The rest of the document appears to be part of a marketing presentation focusing on food adulteration issues in Bangladesh and developing an awareness campaign.
The topic was to design a nation-wide campaign against food-adulteration with a target of reducing adulteration by a significant percentage within the next five years. This presentation won us the biggest branding/marketing competition in the country, Brandwitz '14.
The document discusses analyzing a company's marketing environment. It identifies several factors in the macro environment including political, economic, social/cultural, technological, legal, and demographic factors. It also discusses micro environmental factors including the market/demand, customers, industry/competition, suppliers, and government policies. Regular environmental analysis is important for understanding opportunities and threats and formulating the right marketing strategy to align with the current environment.
This document provides an introduction to microeconomics. It defines economics as the study of how individuals and societies choose to employ scarce resources. It discusses four main definitions of economics from classical economists like Adam Smith to modern economists. It then distinguishes between microeconomics and macroeconomics, with microeconomics focusing on individual units like firms and resource allocation, and macroeconomics studying overall aggregates like total production and consumption. The document also covers different types of economies (capitalist, socialist, mixed), central economic problems of resource allocation, and production possibility curves to illustrate scarcity.
This document discusses demand for health care and factors that influence demand. It covers the distinction between need and want, Grossman's model of demand for health, and factors like income, prices of substitutes and complements, insurance, and elasticity. The key points are that demand is derived from demand for health, it is influenced by many individual and environmental factors, and having insurance decreases price sensitivity by consumers.
The document discusses factors that can affect demand beyond just price. These factors include consumer income, expectations, population change, and tastes/trends. Changes in these non-price factors do not cause movement along the demand curve, but instead shift the entire demand curve, either to the right if demand increases or to the left if demand decreases. Examples are given for how each factor can impact demand for certain goods.
The document discusses the key determinants of market demand for a product. It identifies 10 factors that influence demand: 1) price of the product, 2) price of related goods like substitutes and complements, 3) consumer income, 4) tastes and preferences, 5) advertising, 6) consumer expectations, 7) demonstration effect, 8) availability of consumer credit, 9) population size, and 10) distribution of national income. These determinants impact the total quantity demanded in the market through their influence on individual consumer demands.
This is a small and easy description of demand and its determinants. PLEASE MUST WATCH IT AND UNDERSTAND IT AND ASK YOUR QUARRIES ALSO , i would love to solve it and give your peaceful reviews regarding this presentation weather it is bad or good.

1) Demand refers to an effective desire for a commodity, backed by the ability and willingness to pay for it. Demand depends on factors like price, income, tastes, expectations about future prices, and advertising.
2) Individual demand refers to what one consumer will buy, while market demand is the total demand from all consumers. Market demand determines sales and prices.
3) Factors that influence demand include price, income, tastes, prices of substitutes and complements, expectations, advertising, number of consumers, and economic conditions.
The document discusses the concept of demand, including the three conditions for demand, types of demand (price, income, cross), and nature of demand. It provides examples of different types of demand including consumer vs producer goods, autonomous vs derived demand, durable vs perishable goods, firm vs industry demand, and short run vs long run demand. The document also discusses demand functions, the law of demand and its assumptions, exceptions to the law of demand, and the significance of the law of demand.
Demand analysis(determinants,change and law).pptxVivekKumar614401
This document provides an overview of demand analysis. It defines demand and explains that demand is relative to both time and price factors. It then discusses different types of demand such as individual vs market demand, autonomous vs derived demand, and short-term vs long-term demand. The document also examines the determinants that influence demand, such as price, income, tastes and preferences. It introduces the concept of demand schedules and curves. Finally, it covers the law of demand and some exceptions to this law.
This document discusses demand analysis and the law of demand. It begins by defining demand in economics as a desire backed by both willingness and ability to purchase. The law of demand states that quantity demanded increases when price decreases and decreases when price increases, assuming all other factors remain constant. The document then provides an example demand schedule and derives a demand curve from it. It lists several assumptions of the law of demand and possible exceptions, such as Giffen goods. Finally, it identifies 10 factors that can influence demand, including price, income, tastes, expectations, and business/economic conditions.
This document provides an overview of demand analysis. It defines key demand concepts like individual demand, market demand, direct vs derived demand, recurring vs replacement demand, complementary vs competing demand, demand function, demand schedule, demand curve, and law of demand. It outlines the assumptions and possible exceptions to the law of demand. Finally, it discusses how demand analysis serves important managerial purposes like sales forecasting, demand manipulation, product planning, and determining pricing policy.
This document discusses demand, supply, and the laws of demand and supply. It begins by defining demand and the factors that influence demand, including income, population, and expectations. It then defines individual and market demand. Similarly, it defines supply and discusses factors that influence supply. It introduces the laws of demand and supply - the inverse relationship between price and quantity demanded, and the direct relationship between price and quantity supplied. The document also discusses supply and demand schedules and curves, and how equilibrium price is determined by the intersection of the supply and demand curves.
This document defines demand and discusses the key factors that influence it. It provides:
1. A definition of demand as the desire, ability, and willingness to purchase a product.
2. An explanation of the law of demand, which states that as price increases, quantity demanded decreases.
3. Details several factors that can cause a shift in the demand curve, such as changes in income, tastes, prices of substitutes and complements, and number of consumers.
4. Discusses concepts like price elasticity, inelastic demand, and unitary elasticity in measuring responsiveness of quantity demanded to price changes.
This document discusses demand analysis and supply analysis. It defines demand as a relationship between price and quantity demanded, outlines the three things essential for desire to become effective demand, and describes the three alternative ways to express demand: demand function, demand schedule, and demand curve. It then discusses factors that affect demand, types of demand, and exceptions to the law of demand. The document also defines supply, outlines the law of supply, and explains how supply curves depict the relationship between price and quantity supplied. It concludes by interpreting how changes in demand and supply can shift the equilibrium price and quantity in a market.
The document discusses different types of demand, including individual demand versus market demand, total market demand versus market segment demand, derived demand versus direct demand, industry demand versus company demand, short-run demand versus long-run demand, price demand versus income demand, and cross demand. It provides definitions and examples for each type of demand.
This document discusses the concept of demand, types of demand, factors affecting demand, and elasticity of demand. It defines demand as the desire, ability, and willingness to purchase a product. The two main types of demand are individual demand and market demand. Market demand is the total of individual demands. Factors that influence demand include price, income, tastes, availability of substitutes, and expectations of future prices. Elasticity of demand refers to the responsiveness of quantity demanded to price changes. There are different types of elasticities such as perfectly inelastic, relatively elastic, and unitary elastic demand.
Demand refers to how much of a good or service consumers are willing and able to purchase at a given price. It depends on consumers' desire and ability to pay, as well as the good being available at a certain price, place, and time. Demand is determined by factors like price, income, prices of related goods, tastes, expectations, and the number of buyers. The relationship between price and quantity demanded is shown through a demand schedule and demand curve, which has a negative slope as per the law of demand. A change in any determinant can cause the demand curve to shift, changing the overall relationship between price and quantity demanded.
Demand analysis is important for business success as sales depend on market demand. Failure to properly estimate demand can negatively impact business, as seen with Kellogg's and McDonalds in India in the 1990s. Demand serves several purposes including sales forecasting, product planning, and determining pricing. The law of demand generally states that as price increases, quantity demanded decreases, and vice versa. However, there are some exceptions including Giffen goods, goods with snob appeal, and situations involving speculation. A demand curve graphically shows the relationship between price and quantity demanded.
The document discusses key concepts in microeconomics including demand, the law of demand, demand schedules, demand curves, determinants of demand, elasticity of demand, and how to measure elasticity. Specifically, it defines demand as the quantity of a good consumers are willing and able to purchase at various prices in a given time period. It explains that the law of demand states that as price increases, quantity demanded decreases, and vice versa. Demand schedules and curves illustrate the relationship between price and quantity demanded. Factors like income, tastes, prices of related goods, and expectations can cause shifts in the demand curve. Elasticity refers to the responsiveness of quantity demanded to price changes, and can be elastic, inelastic,
1) Demand refers to how much of a good or service is desired by buyers at various prices. It is represented by a demand curve showing the relationship between price and quantity demanded.
2) Demand is determined by factors such as price, income, tastes, prices of substitutes and complements, and expectations about future prices and income.
3) The law of demand states that, all else equal, quantity demanded is inversely related to price - as price increases, quantity demanded decreases, and vice versa.
1. Demand refers to how much of a good or service is desired by buyers at various prices and is determined by factors like price, income, tastes, and expectations of buyers.
2. The relationship between price and quantity demanded is known as the demand curve, which slopes downward as quantity demanded decreases when price increases.
3. A shift in the demand curve occurs when a change in a determinant of demand causes a different quantity to be demanded at each price, while movement along the curve refers to changes in quantity demanded due to price changes with other factors held constant.
Laws are rules that are recognized as binding by the governing authority in a society or state. They aim to guide behavior, and if broken, can result in punishment being enforced through the court system or other government agencies. The development of laws plays an important role in regulating human interactions and maintaining order, safety, and justice within a community.
The document discusses the economic concepts of demand and supply. It defines demand as the quantity of a good or service that consumers are willing and able to purchase at various price points. Supply is defined as the quantity of a good or service that producers are willing to supply at various price points. The price of a good or service is determined by the interaction of supply and demand in the market. Demand curves slope downward to show that as price increases, quantity demanded decreases, assuming other factors remain constant. A change in demand results from factors like income, tastes, or prices of related goods, causing the entire demand curve to shift.

2. DEMAND
The success of a business largely depends on
sales. Sales depend on market demand
behavior. Market demand analysis is a core
topic in managerial economics, for it seeks to
search out and measures the determinants of
demand, thus, forces governing sales of a
product.
3. Market Demand analysis serves the
following managerial purposes :
• It is an important technique for sales
forecasting with a sound base and greater
accuracy.
• It provides a guideline for demand
manipulation through advertising and sales
promotion programmes.
• It shows direction to product planning and
product improvement
4. CONTD.
• It is useful in determining the sales quotas and
appraisal of performance of the personnel in
Sales Department.
• It is an anchor for the pricing policy.
• It indicates the size of the market for given
product and the market share of the concerned
firm.
• It thus, reflects the scope of business
expansion and competitive position of the firm
in market trend.
5. MEANING OF DEMAND
The economics meaning of demand refers the
effective demand, i.e., the amount the buyers
are willing to purchase at a given price and
over a given period of time.
From managerial economics point of view,
thus, the concept of demand may be looked
upon as follows :
6. 1. Demand is the Desire or Want Backed
up by Money.
Demand means effective desire or want for
a commodity, which is backed up by the
ability (i.e., money or purchasing power)
and willingness to pay for it.
7. 2. Demand is Always Related to Price and
Time.
Demand is not an absolute term. It is a
relative concept. Demand for a commodity
should always have a reference to price and
time. For instance, and economist would
say that the demand for grapes by a
household, at a price of Rs.40 per kg, is 10
kilograms per week.
8. 3. Demand may be Viewed Ex-Ante or
Ex-Post.
Demand for a commodity may be viewed as
ex-ante, i.e., intended demand or ex-post,
i.e., what is already purchased. The former
denotes potential demand, while the latter
refers to the actual amount purchased.
9. INDIVIDUAL DEMAND AND MARKET DEMAND
Consumer demand for a product may be viewed at
two levels :
(i) Individual demand, and
(ii) Market demand
10. Individual demand refers to the demand for a
commodity from the individual point of view. The
quantity of a product consumer would buy at a given
price over a given period of time is his individual
demand for that particular product. Individual demand
is considered from one person’s point of view or from
that of a family or household’s point of view.
Individual demand is a single consuming entity’s
demand.
11. Market demand for a product, on the other hand, refers
to the total demand for all the buyers, taken together.
Market demand is an aggregate of the quantities of a
product demanded by all the individual buyers at a
given price over a given period of time.
Market demand function is the sum total of individual
demand function. It is derived by aggregating all
individual buyer’s demand function in the market.
12. Market demand is more important from the business
point of view. Sales depend on the market demand.
Business policy and planning are based on the market
demand. Prices are determined on the basis of market
demand for the product. In a competitive market,
interaction between total or market demand and
market supply determine the equilibrium price.
13. Under monopoly also the seller has to determine the
price of his product with due consideration to the
position of market demand. He simply cannot
determine any high price, disregarding the market
demand for product.
14. Usually, under market mechanism, resources would be
automatically channeled in producing those goods
which has a greater intensity of market demand and
consequently, higher prices and more profitability.
Market demand, thus, serves as a guidepost to
producers in adjusting their supplies in a market
economy.
15. DETERMINANTS OF DEMAND
Demand for a commodity depends on a number of
factors. Several factors may affect the individual
demand for a product. Likewise, the market demand
for a product is influenced by many factors. We shall
identify some of the major determinants of demand as
under :
16. Factors Influencing Individual Demand
All individual’s demand for a commodity is generally
determined by such factors as :
Price of the Product. Usually, price is a basic
consideration in determining the demand for a
commodity. Normally, a larger quantity is demanded
at a lower price than at a higher price.
17. Income. A buyer’s income determines his/her
purchasing capacity. Income is, therefore, and
important determinant of demand. Obviously, with the
increase in income one can buy more goods. Rich
consumers usually demand more and more goods
than poor customers. Demand for luxuries and
expensive goods is related to income.
18. Tastes, Habits and Preference. Demand for many
goods depends on the person’s tastes, habits and
preferences. Demand for several products like ice-
cream, chocolates, beverages and so on depends on
individual’s tastes. Demand for tea, betel, cigarettes,
tobacco, etc.is a matter of habits.
19. People with different tastes and habits have different
preference for different goods. A strict vegetarian will
have no demand for meat at any price, whereas a non-
vegetarian who has liking for chicken may demand it
even at a high price. Similar is the case with demand
for cigarettes by non-smokers and smokers.
20. Relative Prices of Other Goods – Substitute and
Complementary Products. How much the consumer
would like to buy of a given commodity, however, also
depends on the relative prices of other related goods
such as substitute or complementary goods to a
commodity.
When a want can be satisfied by alternative similar
goods, they are called substitutes. For example, peas
and beans, groundnut oil and til oil, tea and coffee,
jowar and bajra, etc. are substitutes of each other.
21. The demand for a commodity depends on the relative
price of its substitutes. If the substitutes are relatively
costly, then there will be more demand for this
commodity at a given price than in case its substitutes
are relatively cheaper.
Similarly, the demand for a commodity is also affected
by its complementary product. When in order to
satisfy a given want, two or more goods are need in
combination, these goods are referred to as
complementary goods.
22. For example, car and petrol, pen and ink, tea and sugar,
shoes and socks, sarees and blouses, gun and bullets, etc.
are complementary to each other. Complementary goods
are always in joint demand. If a given commodity is a
complementary product its demand will be relatively high
when its related commodity’s price is lower than otherwise.
Or, when the price of one commodity decreases, the
demand for its complementary product will tend to increase
and vice versa. For example, a fall in the price of cars will
lead to an increase in the market demand for petrol.
23. Consumer’s Expectation. A consumer’s expectation
about the future changes in the price of a given
commodity also may affect its demand. When he
expects its prices to fall in future, he will tend to buy
less at the present prevailing low price. Similarly, if he
expects it price to rise in future, he will tend to buy
more at present.
24. Advertisement Effect.
In modern times, the preferences of a consumer can
be altered by advertisement and sales propaganda,
albeit to a certain extent only. In fact, demand for
many products like toothpaste, toilet soap, washing
powder, processed foods, etc. is partially caused by
the advertisement effect in a modern man’s life.
25. Factors Influencing Market Demand
The market demand for a commodity originates and is
affected by the form and change in the general demand
pattern of the community of the people at large. The
following factors affect the common demand pattern for
a product in the market.
• Price of the Product.
At a low market price, market demand for the product
tends to be high and vice versa.
26. Distribution of Income and Wealth in the
Community.
If there is equal distribution of income and wealth, the
market demand for many products of common
consumption tends to be greater than in the case of
unequal distribution.
27. Community’s Common Habits and Scale of
Preferences.
The market demand for a product is greatly influenced
by the scale of preferences of the buyers in general.
For example, when a large section of population shifts
its preferences from vegetarian foods to non-vegetarian
foods, the demand for the former will tend to decrease
and that for the latter will increase.
28. General Standards of Living and Spending Habits
of the People.
When people in general adopt a high standard of living
and are ready to spend more, demand for many
comforts and luxury items will tend to be higher than
otherwise.
29. Number of Buyers in the Market and the Growth of
Population.
The size of market demand for a product obviously
depends on the number of buyers in the market. A
large number of buyers will usually constitute a large
demand and vice versa. As such, growth of
population over a period of time tends to imply a rising
demand for essential goods and services in general.
30. Age Structure and Sex Ratio of the population.
Age structure of population determines market
demand for many products in a relative sense. If the
population pyramid of a country is broad based with a
large proportion of juvenile population, then the
market demand for toys, school bags, etc. goods and
services required by children will be much higher than
he market demand for goods needed by the elderly
people.
31. Similarly, sex-ratio has its impact on demand for many
goods. An adverse sex ratio, i.e.females exceeding
males in number (or, males exceeding females as in
Mumbai) would means a greater demand for goods
required by the female population than by the male
population (or the reverse).
32. Future Expectations. If buyers in general expect that
prices of a commodity will rise in future, then present
market demand would be more as most of them would
like to hoard the commodity. The reverse happens if a
fall in the future prices is expected.
33. Level of Taxation and Tax Structure. A
progressively high tax rate would generally mean a
low demand for goods in general and vice versa. But,
a highly taxed commodity will have a relatively lower
demand than an untaxed commodity-if that happens
to be a remote substitute.
34. • Inventions and Innovations. Introduction of new
goods or substitutes as a result of inventions and
innovations in a dynamic modern economy tends to
adversely affect the demand for the existing products,
which as a result of innovations, definitely become
obsolete. For example, the advent of electronic
calculators has made adding machine obsolete.
35. • Fashions.
Market demand for many products is affected by
changing fashions. For example, demand for
commodities like jeans, salwar-kameej, etc. is based
on current fashions.
36. Climate or Weather Conditions. Demand for certain
products is determined by climatic or weather
conditions. For example, in summer, there is a greater
demand for cold drinks, fans, coolers,e tc. Similarly,
demand for umbrellas and rain coats is seasonal.
Customs. Demand for certain goods is determined by
social customs, festivals, etc. For example, during
Dipawali days, there is a greater demand for sweets
and crackers and during Christmas, cakes are more in
demand.
37. Advertisement and Sales Propaganda. Market demand
for many products in the present day is influenced by
the sellers’ efforts through advertisements and sales
propaganda. Demand is manipulated through sales
promotion. When these factors change, the general
demand patterns will be affected, causing a change in
the market demand as a whole. Of course, there is
always a limit.
38. DEMAND FUNCTION
A demand function in mathematical terms expresses
the functional relationship between the demand for the
product and its various determining variables.
Dx = f(Px,Ps,Pc,Yd, T, A, N, u)
39. THE DEMAND CURVE
A demand curve is a graphical presentation of a
demand schedule. When price quantity information of a
demand schedule is plotted on the graph, a demand
curve is drawn. Demand curve thus depicts the picture
of the data contained in the demand schedule. It
relates the amount the consumer is willing to buy at
each alternative conceivable price for the commodity
over a given period of time.
40. THE LAW OF DEMAND
The law of demand describes the general tendency of
consumers’ behavior in determining a commodity in
relation to the changes in its price. The law of demand
expresses the nature of functional relationship between
two variable of the demand relation, viz, the price and
the quantity demanded. It simply states that demand
varies inversely to changes in price. The nature of this
inverse relationship stressed by the law of demand
which forms one of the best known and most significant
laws in economics.
41. THE LAW OF DEMAND
Statement of the Law of Demand. Ceteris Paribus, the
higher the price of a commodity, the smaller is the
quantity demanded and lower the price, larger the
quantity demanded.
In other words, the demand for a commodity extends
(i.e., the demand rises) as the price falls and contracts
(i.e. demand falls) as the price rises. Or briefly stated,
the law of demand stresses that, other things remaining
unchanged, demand varies inversely with price.
42. The conventional law of demand, however, relates to
the much simplified demand function :
D = f (P)
Where,D represents demand,P the price and f,connotes
a functional relationship. It, however, assumes that
other determinants of demand are constant, and only
price is the variable and influencing factor.
43. The relation between price and quantity of demand is
usually an inverse or negative relation, indicating a
larger quantity demanded at a lower price and smaller
quanity demanded at a higher price.
44. Assumptions Underlying the Law of Demand
The law of demand is conditional. It is based on certain
conditions as given. It is, therefore, always stated with
the ‘other things being equal.’ It relates to the change
in price variable only, assuming other determinants of
demand to be constant. The law of demand is, thus,
based on the following ceteris paribus assumptions :

demand to be constant. The law of demand is, thus,
based on the following ceteris paribus assumptions :
46. Assumptions Underlying the Law of Demand
No Change in Consumer’s Income. Throughout the
operation of the law, the consumer’s income should
remain the same. If the level of a buyer’s income
changes, he may buy more even at a higher price,
invalidating the law of demand.
No Change in Consumer’s Preferences. The
consumer’s taste, habits and preference should remain
constant.
47. No Change in the Fashion. If the commodity
concerned goes out the fashion, a buyer may not buy
more of it even at a substantial price of reduction.
No Change in the Price of Related Goods. Price of
other goods like substitutes and supportive, i.e.
complementary or jointly demanded products remain
unchanged. If the prices of other related goods
change, the consumer’s preferences would change
which may invalidate the law of demand.
48. No Expectation of Future Price Changes or
Shortages.
The law requires that the given price change for the
commodity is a normal one and has no speculative
consideration. That is to say, the buyers do not expect
any shortages in the supply of the commodity in the
market and consequent future changes in the prices.
The given price change is assumed to be final at a
time.
49. No Change in Size, Age Composition and Sex Ratio
of the Population. For the operation of the law in
respect of total market demand, it is essential that the
number of buyers and their preferences should remain
constant. This necessitates that the size of population as
well as the age structure and sex ratio of the population
should remain the same throughout the operation of the
law. Otherwise, if population changes, there will be
additional buyers in the market, so the total market
demand may not contract with a rise in price.
50. No Change in the Range of Goods Available to the
Consumers.
This implies that there is no innovation and arrival of
new varieties of product in the market which may distort
consumer’s preferences.
No Change in the Distribution of Income and Wealth
of Community.
There is no redistribution of incomes either, so that the
levels of income of the consumers remain the same.
51. No Change in Government Policy. The level of
taxation and fiscal policy of the government remains the
same throughout the operation of the law. Otherwise,
changes in income-tax, for instance, may cause
changes in consumer’s income or commodity taxes
(sales tax or excise duties) and may lead to distortion in
consumer’s preferences.
52. No Change in Weather Conditions.
It is assumed that the climatic and weather conditions
are unchanged in affecting the demand for certain goods
like woolen clothes, umbrellas,etc.
