為什麼 short run 入面我地會用marginal cost而唔係average total cost去做supply curve既??
above average total cost唔係就已經有錢賺架喇咩 @@?
many thanks!!

✔ 最佳答案
Average total cost is marginal cost plus fixed cost, in the short run, price above marginal cost is already make profit and can keep the company running. Hence, we use marginal cost curve to represent supply curve in the short run.

supply curve shows quantity supplied at different prices.
Average cost 只能決定在某PRICE要不要生產
意思就是在某PRICE以上的RANGE都能生產,不能決定是哪一個數量
FIRM的目標是要profit max,MR=MC
在perfectly competitve的情況下,MR=P
所以MC=P,佢先可以reflect到個supply.
