2.
a. Calculate the TR and MR per download
| Price per download | Downloads demanded | Total revenue | Marginal revenue |
|---|---|---|---|
| $10 | 0 | $0 | $0 |
| $8 | 1 | $8 | $8 |
| $6 | 3 | $18 | $5 |
| $4 | 6 | $24 | $2 |
| $2 | 10 | $20 | $-1 |
| $0 | 15 | $0 | $-4 |
At $6 we have 2 extra downloads than at $8. The difference in revenue between the download at $8 and $6 is $10 divided by the 2 extra units sold yields a marginal revenue of $5.
At $4 we have extra 3 downloads than at $6 ($24 - $18 =6 / 3 =2)
At $2 we have extra 4 downloads than at $4 ($20 - $24 = -4 / 4 = -1)
At $0 we have extra 5 downloads than at $2 ($-20 of lost revenue / 5 = $-4)
b. A ought to charge $0 to have the maximum 15 downloads.
c. B would choose the $4 price and would get 6 downloads with a revenue of $24.
d. C should charge $6 hence getting 3 downloads since if he had more downloads, marginal revenue would be lower than the marginal cost of $4.
e. D ought to charge $4 for an efficient price and he would get 6 downloads. Revenue which is equal to the marginal cost ($6 * $4 =$24 revenue.)
