顯示性偏好理論 - 經濟

※ 引述《looksir (123)》之銘言：
: revealed preference theory內容到底是在討論什麼?
: 是在探討有沒有違反WARP(weak axion of revealed preference)嗎?
: 還是在討論消費者有沒有理性
: 舉個例題
: 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?
: 這樣子我該怎麼判斷呢?

A(5,20) B(20,5) C(10,10)
────┼─────┼────┼─────
(4,2) │ 60 │ 90 │ 60 (A prefer C B買不起)
────┼─────┼────┼─────
(2,4) │ 90 │ 60 │ 60 (B prefer C A買不起 )

所以這裡沒有違反WARP
