Module 2: |
| |
| 1. The cost curve of a generator is C(q)=25q2+2000q=500INR , where C is the total cost and q is the quantity produced. What is the marginal cost of a generator at 50 MW?
|
| |
| 2.In a perfectly competitive market, the market price can be manipulated by |
| |
- a) A single player
- b) Some dominant players
- c) Nobody
d. All players
|
| |
| 3. Average cost curve of a generator is given by the function:AC(q)=(50q2+2000q+800)/q . At what generation level will the marginal cost (MC) curve meet average cost (AC) curve? |
| |
| 4.Marginal cost (MC) of a generator isπ(q)=5q+50INR/MW. If, for a perfectly competitive market, MCP is 100 INR/ MW, what is the marginal revenue of that generator? |
| |
| 5. The cumulative supply function is: . The cumulative demand function is: . Calculate supplier surplus and the demand surplus in INR. |
| |
| 6.Comment on which demand is ‘more price elastic’? |
| |
- a) the one having larger absolute slope for demand function
- b) the one having smaller absolute slope of demand function
|
| |
| |
| 7. Three Gencos (all having infinite power generating capacity) provide bids into market as follows: |
| |
| Genco A: 10 INR / MW |
| Genco B: 5 INR / MW |
| Genco C: |
| Calculate MCP for inelastic demand of 10 MW. |
