强帖强帖，第一次来论坛就让我瞄到这个贴。哈哈。

有福啊~

估计是现实中恋爱不成，跑来做理论分析来了

Such a good economic application addressing campus love issues!

I thought 2 more questions last night: 

Question (1)how about the elasticity of demand & supply? Generally, long-run demand or supply suffers less impacts of some short-term factors, such as once or twice bad performance before the girls or boys you like.After all, in some cases, if a male/female doesn't think you are his/her perfect match for the first glance, I guess the probability of your success wouldn't change very dramatically in the short run(say several months), regardless of how many dinners you have paid for him/her.But as she/he understands you more & long enough(several years?), your figure may change in her/his mind gradually.In another word, you give her/him a period of time to balance between yr weakness & advantages comprehensively and then make the decision,which can't be modified by your coincident good performance but some fix character & personality.So basically, the No.1 factor for campus love should be the one can bear the test of time.

Question (2): Whether it makes sense to quantify the relationship between dependent variable (e.g. success or failure in chasing a girl) & independent variable (physical attractiveness, talent, capacity...) We can detect who tends to attract more appreciation from the opposite sex.

For instance, if a girl gives more weight on the "good looking" , then the boys handsome in her eyes will receive more scores;if another girl emphasizes more on the "talent","potential of future earning power" etc.,then such guys will benefit. After all, from intuition, we have known some factors' importance.But can we find some empirial evidence to support our intuition. From example, is there some boundery for the effects of "physical attractiveness"? Say some beautiful girls/boys also remain single for a long time, how to explain?maybe due to the distance formed for some reason bet.them with the "normal-looking"classmates. 

要是能在恋爱中做一个理性人，那就是强人勒。。。都说恋爱中的人智商为零，也许真的进入角色了就不可能去按照所谓经济学的思路去剖析自己，剖析对方，所谓“当局者迷，旁观者清”。

恋爱时“当局者迷，旁观者清”这个说法似是而非。为何一般人都选择外表漂亮、有内涵、有修养、有个性又能使双方都满意，能长期合作的伴侣呢？而不是胡乱选择一个了事呢？

“当局者迷”的说法，我认为是没有具体了解当局者的具体条件，没有了解当局者在具体条件下的用值及成本约束所导致的，你一个“旁观者清”与他“当局者迷”所处的具体条件与具体成本，是不同的，要解释现象，个人认为要从当事者的角度解释，要从当事者所处的具体条件与成本约束来解释当事者的恋爱行为。

同意楼上，创新才是王道，望LZ再接再厉！另祝LZ考研顺利！

还是比较好玩的

爱情是个烫手的芋头

呵呵，好有意思~~~~楼主想象力挺丰富

善于观察啊

挺有意思的,经济学引入爱情里。

楼主能不能把这些成本进行量化一下，那就简单易懂了

写的很好啊，顶啊
