When does a production function satisfy increasing returns to scale?
Increasing returns to scale (IRS) holds when a proportional increase in all the factors of production leads to an increase in the output by more than the proportion. For example, if both the labour and the capital are increased by ‘n’ times, and the resultant increase in the output is more than ‘n’ times, then we say that the production function exhibits IRS.
Algebraically, IRS exists when,
F (nL, nK) > n. f (L, K)

0 0 0 1 2 3 4 |
0 0 0 1 2 3 4 |
At what level of price do the firms in a perfectly competitive market supply when free entry and exit is allowed in the market? How is the equilibrium quantity determined in such a market?
At the market price of Rs 10, a firm supplies 4 units of output. The market price increases to Rs 30. The price elasticity of the firm’s supply is 1.25. What quantity will the firm supply at the new price?
How does an increase in the number of firms in a market affect the market supply curve?
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
