顯示性偏好理論 - 經濟

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?
