Class 12 Micro Economics - Chapter Market Equilibrium NCERT Solutions | What will happen if the price prevailing

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?

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?

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

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

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?

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?

Consider a market where there are just two consumers and suppose their demands for the good are given as follows:

Calculate the market demand for the good.

What do you mean by ‘monotonic preferences’?

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.

Explain price elasticity of demand.

What is the law of variable proportions? 

What do the long-run marginal cost and the average cost curves look like? 

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

Explain why the budget line is downward sloping.

Suppose a consumer wants to consume two goods which are available only in
integer units. The two goods are equally priced at Rs 10 and the consumer’s
income is Rs 40.
(i) Write down all the bundles that are available to the consumer.
(ii) Among the bundles that are available to the consumer, identify those which cost her exactly Rs 40.

Explain the relationship between the marginal products and the total product of an input.
