※ 引述《superqm714 (耀楊)》之銘言:
※ 引述《vji (jack)》之銘言:
未飽和性也就是多多益善的意思
至於邊際效用在大於零的時候
增加消費仍然可以使總效用提升 這個時候消費這就會一直增加消費
如果拿掉預算限制的話 最終會消費到哪?
很明顯的在MU=0時就會停止消費了
因為繼續消費的效果只是帶來負的邊際效用(也就是從喜好品變成了厭惡品)
反而會降低了總效用
忘了在哪本書有看到同心圓 那個圓心就是極樂點
也就是X和Y的MU皆為0的臨界點
W大說"預算限制"帶給我ㄧ些啟發
第ㄧ點:極樂點存在而且在預算限制外.因為預算限制的關係,
消費者一直無法達到極樂點,
所以在預算限制下,消費者會採取未飽和性的策略.
第二點:極樂點會移動
消費者隨自身能力的增加,求得極樂境界所需的貨品也跟著增加
所以極樂點會移動
