Class 12 Micro Economics - Chapter Market Equilibrium NCERT Solutions | Suppose the market determined rent for a

How will a change in the price of coffee affect the equilibrium price of tea? Explain the effect on equilibrium quantity also through a diagram. 

When do we say that there is an excess demand for a commodity in the market?

Suppose the price at which the equilibrium is attained in exercise 5 is above the minimum average cost of the firms constituting the market. Now if we allow for free entry and exit of firms, how will the market price adjust to it?

Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.

When do we say that there is an excess supply for a commodity in the market?

How are equilibrium price and quantity affected when income of the consumers

a) Increase

b) Decrease

Explain market equilibrium.

Explain how price is determined in a perfectly competitive market with a fixed number of firms.

In what respect do the supply and demand curves in the labor market differ from those in the goods market?

Suppose the demand and supply curves of salt are given by:

(a) Find the equilibrium price and quantity.

(b) Now, suppose that the price of an input that used to produce salt has increased so, that the new supply curve is qs = 400 + 3p

How does the equilibrium price and quantity change? Does the change conform to your expectation?

(a) Suppose the government has imposed at ax of Rs 3 per unit of sale on salt. How does it affect the equilibrium rice quantity? 

Explain the concept of a production function

What would be the shape of the demand curve so that the total revenue curve is?

(a) A positively sloped straight line passing through the origin?

(b) A horizontal line?

Discuss the central problems of an economy.

What are the characteristics of a perfectly competitive market?

What do you mean by the budget set of a consumer?

What is the total product of input?

From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

What do you mean by the production possibilities of an economy?

How are the total revenue of a firm, market price, and the quantity sold by the firm related to each other?

What is budget line?

Suppose the price elasticity of demand for a good is – 0.2. How will the expenditure on the good be affected if there is a 10 % increase in the price of the good?

What do you mean by substitutes? Give examples of two goods which are substitutes of each other.

What are the average fixed cost, average variable cost and average cost of a firm? How are they related? 

Suppose there are 20 consumers for a good and they have identical demand functions: 

d(p)=10–3pd(p)=10–3p for any price less than or equal to 103103 and d1(p)=0d1(p)=0 at any price greater than 103.

Suppose there are two consumers in the market for a good and their demand functions are as follows:

d1(p) = 20 – p for any price less than or equal to 20, and d1(p) = 0 at any price greater than 20.

d2(p) = 30 – 2p for any price less than or equal to 15 and d1(p) = 0 at any price greater than 15.

Find out the market demand function.

How does the budget line change if the consumer’s income increases to Rs 40 but the prices remain unchanged?

At which point does the SMC curve intersect the SAC curve? Give a reason in support of your answer. 

What do you mean by the production possibilities of an economy?

What is the marginal product of an input? 

Explain why the budget line is downward sloping.
