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?

墨尔本考，上下午感觉难度相当,比Mock简单很多，和sample差不多难度。 很多题都不用转弯，直接套数字就行了...什么么唉

上午一个半小时做完，下午的也用了差不多的时间。 反正都检查了一遍，然后正好3个小时用完：）

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?

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?

it asks if  the companies have "any" power, no matter it's short/long run, in monopolistic market, there are price-searchers with differential products, the companies got to find the right prices for their products.therefore, they have power to determine their products' prices.
