What do you think about my answer?

Sorry, I was doing my C++.

Your theory is right, but I think both are not mandatory for living. (no harm without it), people do have to have al to live, or have fun or whatever. so it is more elastic.

And they are only drinks, not as water which is unignorable element.

我的回答是:

a) alcohol is more elastic than pepsi because there are more substitutes for pepsi such as coke, 7up ect

b)natural gas over the next 5 years is more elstic because in the short-run people would still purchase gas (maybe less than the amount they would normally pump in their cars), but in the long-run they would start taking public transportations / moving closer to work ect

b)doors cd is more elastic than all other rock cds because doors cd is a narrower market than the market for all rock cds, and narrow markets tend to have more elastic demand than broadly defined markets since its easier to find close substitutes for narrwly defined goods

d)doritos is more elastic than food,due to the same reason as in part c

not agree with B and C,, my answer is the other way round.

我觉得你的A好象矛盾了
书上的定义是说,Something has more substitutes is more elastic

That is right. But you need to think that pepsi and al. are both drink, so both is sub for the other.

So,you mean Al is more elastic than Pepsi?

 

[jackywyy]

sorry, read your writing wrong about C.

And about B, don't remember. I put next to zero effort, so ... you maybe right. But Al. is elastic for sure.

yes, think how many people drink pop instead of al.

 

[jackywyy]

And I think you 'd better ask people from your class instead of me. Anyhow, I am not in the class.

And, would you please explain B?
