发帖数: 3 | 1 If I am an energy-conservation-minded consumer who can't
afford to rent a new car, should I rent a 10-year old Buick
($100/year, 20 miles per gallon) or a 10-year old Toyota
($300/year, 40 mpg)? What does my choice depend upon?
Explain. | j******u

1/20mpg and 1/ 40 mpg as flexiable cost

发帖数: 10 | 3 it depends on your utility function. Given that you are very energy-conservative
minded, your utility function places more weights on how energy conservative
your car is.. and depending how much the weight is, you have different
conclusions. i mean, it all boil down to how you set up your model..
