Class 12 Micro Economics - Chapter Market Equilibrium NCERT Solutions | At what level of price do the firms in 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. 

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?

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

Suppose the market determined rent for apartments is too high for common people to afford. If the government comes forward to help those seeking apartments on rent by imposing control on rent, what impact will it have on the market for apartments?

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.

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

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

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?

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

The market demand curve for a commodity and the total cost for a monopoly firm producing the commodity are given in the schedules below. 

Use the information given to calculate the following:

(a) The MIR and MC schedules

(b) The quantities for which MIR and MC are equal

(c) The equilibrium quantity of output and the equilibrium price of the commodity

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

The following table gives the average product schedule of labour. Find the total product and marginal product schedules. It is given that the total product is zero at zero level of labour employment. 

The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.

What do you mean by a normal good?

A monopoly firm has a total fixed cost of Rs 100 and has the following demand schedule:

Find the short run equilibrium quantity, price and total profit. What would be the equilibrium in the long run? In case the total cost is Rs.1000, describe the equilibrium in the short run and in the long run.

The following table shows the total cost schedule of a firm. What is the total fixed cost schedule of this firm? Calculate the TVC, AFC, AVC, SAC and SMC schedules of the firm.

What is the marginal product of an input? 

Explain why the budget line is downward sloping.
