What does the price elasticity of supply mean? How do we measure it?
Price elasticity of supply (es ) is defined as the degree of the responsiveness of quantity supplied, to the change in the price of a good.
It is expressed as:
es =
=
=
Where,
∆Q = change in quantity supplied
∆P = change in price
P = initial price
Q = initial supply
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.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?
What is the supply curve of a firm in the long run?
How does the imposition of a unit tax affect the supply curve of a firm?
What is the relation between market price and average revenue of a price-taking firm?
What is the relation between market price and marginal revenue of a price-taking firm?
How does an increase in the number of firms in a market affect the market supply curve?
How does an increase in the price of an input affect the supply curve of a firm?
Compute the total revenue, marginal revenue and average revenue schedules in the following table. Market price of each unit of the good is Rs 10.
Quantity Sold | TR | MR | AR |
---|---|---|---|

Can there be some fixed cost in the long run? If not, why?
At which point does the SMC curve intersect the SAC curve? Give a reason in support of your answer.
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?
Briefly explain the concept of the cost function.
How do the equilibrium price and the quantity of a commodity change when the price of input used in its production changes?
Explain how price is determined in a perfectly competitive market with a fixed number of firms.
Explain market equilibrium.
