第二题，是问american put的下线可能是greater than 0 or ____
理论答案是min(0,X-S)，可选答案是
a.0
b instrinic value
c ex price minus present value of stock price
d stock price mnus ex price

 i think d. was stock price minus the PRESENT VALUE of ex price.

so the answer should be b. INTRINSIC VALUE.

did anyone remember this question?

there was another question about leasing instead of buying the planes.

what would be the benefits of doing so?

1. enjoying a lower tax bracket
2. because they gonna continue leasing the planes for a long time

(cant remember the other 2 choices.)

i picked "enjoying a lower tax bracket" cos leasing = more expenses = low incomes & lower tax.

did anyone have a different answer?

monopolistic competition---price searcher, yes

perfect competition---price taker, no

BearBee, may i know wt the questions is asking about ?

Thanks!

mmm... for monopolistic competition

short run - possible economic profits

long run - new firms enter -> zero economic profits

so it depends whether it was asking abt the long run or the short run

i remember that i picked "no" to both ie. it could be asking abt the long run impact

does anyone remember?
