Chapter 2 Consumer Equilibrium
Tutor | 7:03 AM | Chapter 2 Consumer Equilibrium | 28 comments
Q What do you mean by consumer equilibrium?
Q What is Budget line?
A It refers to attainable combinations of sets of two commodity at given prices of commodity and income of the consumer.
Q Explain the following :-
a) Indifference set
b) Indifference Curve
c) Indifference Map
A a) Indifference set is a set of two commodities which offers the consumer same level of satisfaction, so that he is indifferent between these combinations.
b) Indifference Curve is the diagrammatic presentation of an indifference set. it shows the set of two commodities that offers the consumer the same level of satisfaction, so that he is indifferent between these combinations.
c) Indifference Map refers to a set of indifference curve.
Q Explain relation between MU and TU. [Very Important] 3/4 marks
A Meaning of Consumer Equilibrium :- It is a situation in which a costumer is getting maximum satisfaction and he has no tendency to change his pattern of consumption.
Condition:- MUX = PX
Assumptions :-
a) Utility can be measured in terms of units.
b) Consumer is rational and wants maximum satisfaction.
c) Independent utility
d) MU of money is constant. MU of money is known as worth of a rupee.
e) Law of Diminishing Marginal Utility is applied here
Schedule:- Suppose a consumer is buying orange and the price of each unit of orange is rupee 4, hypothetical MU of orange is given as
Units | MUX | PUX |
1 | 8 | 4 |
2 | 6 | 4 |
3 | 4 | 4 |
4 | 2 | 4 |
Explanation of schedule :- It is evident from the schedule that consumer will purchase four oranges and reaches an equilibrium position.
In this situation the position of the consumer equilibrium MUX (in rupee) is equal to PX is satisfied.
Diagram:-
Q What changes does it make to the quation of consumer equilibrium when he decides to spend his income on two commodity rather than one?
OR
Explain consumer euilibrium in case of double commodity. Very important, 6 marks
Meaning of Consumer equilibrium:- It is a situation in which a consumer is satisfied and he has no tendency to change his pattern of consumption.
Condition:- MUx = MUY = MUM
Q Explain consumer equilibrium with the help of IC (indifference curev) analysis. Very Important( 6 marks)
A Meaning of consumer equilibrium :- it a situation in which a consumer is getting maximum level of satisfaction from a commodity and has no tendency to bring change in pattern of consumption.
Condition :- Px = MRS
Py
Budget Line:- It refers to the attainable combinations of a set of two goods at given prices of goods and income of the consumer.
Explanation of Diagram :- Q shows the equilibrium position where a consumer is getting maximum satisfaction from both the commodity, now if he moves to point T then he will get more satisfaction from good2 and less from Good 1 which is not a situation f equilibrium so he will remain at point Q where he is getting same level of satisfaction from both the commodities.

Points of Difference | Microeconomics | Macroeconomics |
Meaning | Microeconomics studies economic issues at individual level i.e individual firm, individual consumer or household. | Macroeconomics studies economic issues at the level of country as whole. |
Determination | Microeconomics is basically concerned with the determination of output and price for an individual firm or industry | Macroeconomics is basically concerned with the determination of aggregate output and general price level in the economy as whole. |
Constant thing | Study of Microeconomics assumes that macro variable are constant, e.g it is assumed aggregate output is given while we are studying determination of output and price of an individual firm or industry. | Study of Macroeconomics assumes that Micro variable are constant. eg it is assumed that distribution of income remains the constant when we are studying the level of output in the economy. |
Role | Market mechanism plays a significant role like problem of product prising | Government plays a vital role in fixing up the prices. |
Scarcity and choice are inseparable. Discuss
OR
Scarcity and choice goes together, how?
Yes, scarcity and choice are inseparable. It is further cleared by the following:-
i) At consumer level: Here scarcity is limited income and choice is using the income in such a way that a consumer gets maximum satisfaction from it.
ii) At producer lever: Here scarcity is limited resources and choice is allocation of resources in way that there is maximum production of a commodity and a producer gets maximum profit.
iii) At country level: Here scarcity is limited natural resources and choice is allocation of national resources in such a manner that there is maximisation of social welfare at the level of country as whole.
What is positive economic/sentences? Give two sentences.
And
What is normative economic/sentences? Give two sentences.

i) Positive statements do not pronounce value judgement.
ii) Positive statements cannot be verified from the real world.
Normative economic – it refers to what ought to be.
i) Normative statements pass value judgement
ii) These can be verified from the real world.
What are the central problems of the economy? [V.I]
Central problem of the economy are:-
i) What to produce: - Due to scare resources and allocation of resources to alternative use it is very important to decide what to produce and in how much quantity. It is very essential to decide which needs are to be given priority and which can wait.
a) Firstly, economy has to decide what goods and services are to be produce. For instance, it has to be deciding that from consumer goods like wheat, cloth, rice etc what to produce likely from capital goods like machines tractors, from peace time good bread, butter and from war time goods guns riffles what to be produced first.
b) After deciding what good to be produce it is very important to decide in what quantity is to be produced. For e.g. if it is decided that more of war goods will be produced like guns, rifles etc than less of educational goods will be produced like school, colleges etc.
ii) How to produce: - it is very important to decide by which method the production should take place as there two technique to perform the production process. These are :-
a) Labour intensive Technique: In this technique production is done through labours and by adopting this technique there is greater employment.
b) Capital intensive Technique: In this technique production is done through machines and by adopting this work is done efficiently and faster without much wastage of time.
An economy has to decide which technique is to be adopted according to the situation of their country.
iii) For whom to produce: - it is basically concerned with the distribution of the final goods or briefly distribution of the final production. It has two aspects :-
a) First aspect relate to personal distribution: How income generated through production is to be distributed among the society and different individual of household.
b) Second aspect relate to functional distribution: How income generated through production is to be distributed among the Factor of production like land, labour, capital, entrepreneur as a reward for the production.
These are the central problem of every economy.
