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 @@?

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
