When does a production function satisfy decreasing returns to scale?
Decreasing returns to scale (DRS) holds when a proportional increase in all the factors of production leads to an increase in the output by less than the proportion. For example, if both labour and capital are increased by ‘n’ times but the resultant increase in output is less than ‘n’ times, then we say that the production function exhibits
DRS.
F (nL, nK) < n. f (L, K)
What is the total product of input?
Explain the relationship between the marginal products and the total product of an input.
Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve?
The following table gives the total product schedule of labour. Find the corresponding average product and marginal product schedules of labour.

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?
What do you mean by substitutes? Give examples of two goods which are substitutes of each other.
What is the relation between market price and average revenue of a price-taking firm?
A shift in demand curve has a larger effect on price and smaller effect on quantity when the number of firms is fixed compared to the situation when free entry and exits is permitted. Explain.
Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.
What will happen if the price prevailing in the market is?
i. Above the equilibrium price
Ii. Below the equilibrium price

bundles (10, 8) and (8, 6)?
Explain price elasticity of demand.
How does the budget line change if the price of good 2 decreases by a rupee

What are the characteristics of a perfectly competitive market?
Explain how price is determined in a perfectly competitive market with a fixed number of firms.
