※ 引述《looksir (123)》之铭言：
: revealed preference theory内容到底是在讨论什麽?
: 是在探讨有没有违反WARP(weak axion of revealed preference)吗?
: 还是在讨论消费者有没有理性
: 举个例题
: Suppose a consumer spends all of her income in good X and good Y.
: Let bundle A be 5 units of X and 20 units of Y and be written as
: A=(5,20). Similar explanation for the following bundles:
: B=(20,5), C=(10,10)
: the consumer chooses bundle A at price (4,2),the consumer choose B
: at price (2,4). What can you say about consumer's behavior?
: 这样子我该怎麽判断呢?
A(5,20) B(20,5) C(10,10)
────┼─────┼────┼─────
(4,2) │ 60 │ 90 │ 60 (A prefer C B买不起)
────┼─────┼────┼─────
(2,4) │ 90 │ 60 │ 60 (B prefer C A买不起 )
所以这里没有违反WARP
有错请指教搂CC
