if an individual's endowment of x and y is the amount he actually consumes, then a change in relative prices will always make the individual better off. True or false?

✔ 最佳答案
是 false.a change in relative prices 只是講緊 subsutition effect而沒有 income effect
即係沿住原本 tangent 果點 change the slope of budget line
ic curve 不會shift 左 or right
要計埋 income effect 至可以知 better off 定 worse off,
基本上兩個情況都有可能,所以是 false.
參考: 好似係咁,不大肯定

我覺得係fales..
因為佢依家consume左既就係佢既preferrence..
咁轉relative price佢既budget line就會shift..咁買既x同y會唔同左,,
應該會worse off~最多都係no change..唔會better off..
