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?
