Class 12 Micro Economics - Chapter Introduction to Micro Economics NCERT Solutions | What do you mean by the production possi

Distinguish between a centrally planned economy and a market economy.

Distinguish between microeconomics and macroeconomics.

Discuss the subject matter of economics.

What is a production possibility frontier?

What do you understand by normative economic analysis?

What do you understand by positive economic analysis?

Discuss the central problems of an economy.

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?

Explain market equilibrium.

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:

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

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?

What is the total product of input?

If the monopolist firm of Exercise 3 was a public sector firm. The government set a rule for its manager to accept the government fixed price as given (i.e. to be a price taker and therefore behave as a firm in a perfectly competitive market). And the government has decided to set the price so that demand and supply in the market are equal. What would be the equilibrium price, quantity and profit in this case?

What is the law of variable proportions? 

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? 

Suppose the demand and supply curve of commodity XX in a perfectly competitive market are given by:

qD =700 - p

qs = 500 + 3p for p ≥ 15

= 0 or 0 ≤ p <15

Assume that the market consists of identical firms. Identify the reason behind the market supply of commodity X being zero at any price less than Rs 15. What will be the equilibrium price for this commodity? At equilibrium, what quantity of X will be produced?

What do you mean by an ‘inferior good’? Give some examples

Suppose the price elasticity of demand for a good is – 0.2. If there is a 5 % increase in the price of the good, by what percentage will the demand for the good go down?

What is the ‘price line’?

Let the production function of a firm be Q=5L1/2K1/2Q=5L1/2K1/2 Find out the maximum possible output that the firm can produce with 100 units of LL and 100 units of KK.

If duo poly behavior is one that is described by Cornet, the market demand curve is given by the equation q = 200 - 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price.
