我室友問了我一個經濟的問題~~我..我答不出來... 之前就有點似懂非懂的困擾了~~ Q:Sue consumes only sandwiches and soda and is at her best affordable point. Suppose that sandwiches are plotted on the x-axis. Now the price of a sandwich halves. The income effect is ? A: Sue buys more of both goods. 為什麼呢??三明治的價格下降依照所得效果三明治的需求量會上升沒錯但 ""soda的價錢並沒有下降為什麼需求也會上升呢??"" 可以請好心人幫我回答一下嗎??謝謝~感激不盡!! <(_ _)> -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.238.18
