Class 12 Micro Economics - Chapter Production and Costs NCERT Solutions | What is the marginal product of an input

What is the total product of input?

Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve? 

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.

What does the average fixed cost curve look like? Why does it look so? 

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

When does a production function satisfy decreasing returns to scale? 

Explain the concept of a production function

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

Why is the short-run marginal cost curve 'U'-shaped? 

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

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.

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?

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?

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?

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

How are the equilibrium price and quantity affected when?

(a) Both demand and supply curves shift in the same direction?

(b) Demand and supply curves shift in opposite directions?

Discuss the central problems of an economy.

What will happen if the price prevailing in the market is?

i. Above the equilibrium price

Ii. Below the equilibrium price

Suppose a consumer’s preferences are monotonic. What can you say about her preference ranking over the bundles (10, 10), (10, 9) and (9, 9)?

What do you mean by a normal good?

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

What is the supply curve of a firm in the short run?

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.

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?
