Consider a market with two firms. In the following table, columns labelled as SS1 and SS2 give the supply schedules of firm 1 and firm 2 respectively. Compute the market supply schedule.
Price (Rs.) | SS1 (kg) | SS2 (kg) |
---|---|---|
0 1 2 3 4 5 6 7 8 |
0 0 0 1 2 3 4 5 6 |
0 0 0 0 0.5 1 1.5 2 2.5 |
Price | SS1 (kg) | SS2 (kg) | Market Supply = SS1 + SS2 |
---|---|---|---|
0 | 0 | 0 | 0 + 0 = 0 |
1 | 0 | 0 | 0 + 0 = 0 |
2 | 0 | 0 | 0 + 0 = 0 |
3 | 1 | 0 | 1 + 0 = 1 |
4 | 2 | 0.5 | 2 + 0.5 = 2.5 |
5 | 3 | 1 | 3 + 1 = 4 |
6 | 4 | 1.5 | 4 + 1.5 = 5.5 |
7 | 5 | 2 | 5 + 2 = 7 |
8 | 6 | 2.5 | 6 + 2.5 = 8.5 |
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?
How does the imposition of a unit tax affect the supply curve of a firm?
What is the supply curve of a firm in the long run?
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?
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 |
