Suppose you are in charge of a toll bridge that costs essentially nothing to operate. The demand for bridge crossing Q is given by P=15-(1/2)Q.
a. Draw the demand curve for bridge crossings.
b, How many people would cross the bridge if there were no toll?
C. What is the loss of consumer surplus associated with a bridge toll of $ 5?
d. The toll - bridge operator is considering an increase in the toll to $7. Al this higher price ,how many people would cross the bridge? Would the toll bridge revenue increase or decrease? What does your answer tell you about the elasticity of demand?
e. Find the lost consumer surplus associated with the increase in the price of the toll from $5to $7.
Another advantage of money is that it is a measure of value, that is, it serves as a unit in terms of which the relative values of different products can be expressed. In a barter economy it would be necessary to determine how many plates were worth one hundred weight of cotton, or how many pens should be exchanged for a ton of coal, which would be a difficult and time-consuming task. The process of establishing relative values would have to be undertaken for every act of exchange, according to what products were being offered against one another, and according to the two parties'desires and preferences. If I am trying to barter fish bananas, for example, a lot would depend on whether the person willing to barter fish for bananas, for example, a lot would depend on whether the person willing to exchange bananas is or not keen on fish.
Thirdly, money acts as a store of wealth. It is difficult to imagine saving under a barter system. No one engaged on only one stage in the manufacture of a person could save part of his output, since he would be producing nothing complete. Even when a person actually produced a complete product the difficulties would be overwhelming. Most products deteriorate fairly rapidly, either physically or in value, as a result of long storage; even if storage were possible, the practice of storing products for years on would involve obvious disadvantages-imagine a coal-miner attempting to save enough coal, which of course is his product, to keep him for life. If wealth could not be saved, or only with great difficulty, future needs could not be provided for, or capital accumulated to raise productivity.
Using money as a medium of exchange means that______.

听力原文:W: So what are the two main times of the day that you watch TV?
M: Well, a little around breakfast time and then it tends to be really late— eleven or even midnight—when I've finished work.
W: And what sort of programs do you go for?
M: Some news bulletins but I also really like to put my feet up with some of the old comedy shows.
W: Fine. And turning to the new channel...which type of programs would you like to see more of?
M: Well, I certainly don't think we need any more factual programs like news and documentaries. I think we need more about things like local in formation...you know, providing a service for the community. And in the same vein, perhaps more for younger viewers...you know, good quality stuff.
W: Ah ha. And if you had to give the new directors some specific advice when they set up the channel, what advice would you give theme
M: I think I'd advice them to pay more attention to the quality of the actual broadcast, you know, the sound system. They ought to do lots more of these kinds of interview, you know, talking with their potential customers.
W: Oh, I'm glad you think it's valuable!
M: Certainly...yeah.
W: Good. Ok, this will be a commercial channel of course, but how often do you think it is tolerable to have adverts?
M: Well out of that list I'd say every quarter of an hour. I don't think we can complain about that, as long as they don't last for ten minutes each time!
W: Quite. And…would you be willing to attend any of our special promotions for the new channel?
M: Yes, I'd be very happy to, as long as they're held here in my area.
W: Thank you very much for your time.
