Answer 9

Those who can reduce risk should have an incentive to do it: owners of power plants

Question 10

Reduce consequences of natural catastrophes

Answer 10

• Owners and operators of transmission system

- design systems to be able to withstand rare events : enough crews to repair the power system after a hurricane

Question 11

Security margin in power system operation

Answer 11

• Limits the consequences of rare but unpredictable and catastrophic events
• increases the daily cost of electrical energy
• does not cover all possible problems because that would cost too much

Question 12

Question 20

Spot market risks

Answer 20

• Market may not have much depth
• lack of depth causes large price fluctuations
• relying on the spot market for buying or selling large quantities is a bad idea

Question 21

Spot market may not have much depth

-small purchaser may have to buy at a high price
– price risk

Question 23

Forward contract

• Paid at time of delivery
• unconditional delivery

Question 24

How is the forward price set?

Answer 24

-Both parties look at the alternative: spot price

– both forecast what the spot price is likely to be

Question 25

Forward contracts: sharing risk

Answer 25

-In a forward contract, the buyer and the seller share the risk that the price differs from the expectation – difference between contract price and spot price at time of delivery represents a profit for one party and a loss for the other -however, in the meantime they have been able to get on with the business: buy new farm machinery, sell the flour to bakeries

Question 26

Attitude towards risk: expires less risk averse than seller

Answer 26

- Buyer can negotiate a forward price lower than the expected spot price - seller agrees to this lower price because it reduces its risk - difference between expected spot price and forward price is called a premium - premium equals price that seller is willing to pay to reduce risk

Question 27

Attitudes towards risk: if by a small risk averse than seller

Answer 27

- Seller can negotiate a forward price higher than the expected spot price - buyer agrees to this higher price because it reduces its risk - buyer is willing to pay the premium to reduce risk

Question 28

Question 29

Physical participants

Answer 29

-Produce, consume or can store the commodity | – face undiversified risk because they deal in only one commodity

Question 30

Traders a.k.a. speculators

Answer 30

- Cannot take physical delivery of the commodity - diversify the risk by dealing in many commodities - specialise in risk management

Question 31

Trading by speculators

Answer 31

- Cannot take physical delivery of the commodity - must balance their position and date of delivery: quantity bought must equal quantity sold, buy or sell from spot market if necessary - may involve many transactions - forward contracts limited to parties who can take physical delivery - need a standardised contract to reduce the cost of trading: future contract - future contracts (futures) allow others to participate in the market and share the risk

Question 32

Importance of information: speculators

Answer 32

-Speculators own some of the commodity before it is delivered -they carry the risk of a price change during that period -need deep pockets – without additional information, this is gambling -information helps speculators make money -example: global perspective on the harvest for wheat, long-term weather forecast and it’s effect on the demand for gas and electricity
