Suppose the price of a quart of milk rises from $1 to $1.25 and the price of a T-shirt rises from $8 to $10. If the CPI rises from 150 to 175 people will likely buy 答案是: less milk and fewer T-shirts 我是先算牛奶跟t-shirt的CPI 都是125 但是我要怎麼去判斷那兩樣物品該 買多還是 買少... ... 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.160.164.156

相對價格不變 只有所得效果

所以單純只要看CPI的起伏來判斷效果嗎?
