问一道题:NO.PZ2018091702000038

问题如下:

 Weaver discusses how decisions are shaped by the decision-making process itself. She provides the following example:

A new client is interested in becoming an antique car investor and requested I make available $200,000 from his portfolio so he could start his collection. Shortly after the money was made available, the client visited an antique car auction not far from his home. Unfortunately, the auction had a limited number of cars meeting his requirements. He was drawn to one antique car in particular, even though it was missing several of the features he wanted. After some consideration he decided to purchase it anyway. Within an hour, his purchase was placed in storage for safekeeping.”

What behavior did Weaver’s new client most likely demonstrate when he purchased the antique car?

选项:

A.

Satisficing

B.

Utility maximization

C.

Using heuristics

解释:

A is correct.

Weaver’s client most likely demonstrated satisficing when he purchased the antique vehicle. Satisficing combines satisfy and suffice and describes decision, actions, and outcomes that may not be optimal, but are adequate.


选项A: Satisficing属于bounded rationality, 差不多就行。题干中说 “even though it was missing several of the features he wanted. After some consideration he decided to purchase it anyway.” 虽然古董车有一些不符合客户要求的地方,但是这个客户还是买了。A正确。

选项B:utility maximization 题干中没有表现出客户最大化utility, B 错误。

选项C:using heuristics 使用经验,根据过去的经验来决定买不买这辆车,题干中没有这样的表现,C错误。

请问using heuristics 是否也是属于bounded rationality的范畴呢?不也是行为金融学的有限理论吗?谢谢。

嗨,从没放弃的小努力你好


原版书中确实是在bounded rationality这部分提到using heuristics的。书上是这么说的:bounded rattionality指的是"people gather some (but not all) available information, use heuristics to make the process of analyzing the information tractable, and stop when they have arrived at a satisfactory, not necessarily optimal, decision."

这句话的意思是bounded rationality指的是人们收集(但不是全部)一些可用信息,use heuristics使信息分析过程变得容易处理,并停止在不一定是最佳的,但是也是可以接受的结果。

因此use heuristics 可以看成是bounded rationality的一个步骤。

 

做题的时候你要看题目到底是怎么说的, 看出题人想考查的是什么。这道题是协会以前的一道模考题。题目中说“He was drawn to one antique car in particular, even though it was missing several of the features he wanted. After some consideration he decided to purchase it anyway. ” 这个人被一辆古董车所吸引,尽管缺少他想要的一些功能,但是经过考虑他决定还是购买它。这里只说明了这个客户愿意妥协,差不多就行,并没有表现出使用了以前的经验,因此不是using heuristics.

 


 

虽然现在很辛苦,但努力过的感觉真的很好,加油!
