Cost: 由魯賓遜說起 (4)
總結: 分工前 (自給自足):魯賓遜每天可享用 2 尾魚 及 40 隻蕉,而 Friday 每天可享用 4.8 尾魚及 28 隻蕉。魚的總量是 6.8,蕉的總量是 68。 分工後:魚的總量是 9.6,蕉的總量是 80。兩人每天的 total output 增加了 2.8 尾魚和 12 隻蕉。 不過,總產出雖然多了,但魯賓遜只有蕉,而 Friday 只有魚。如果魯賓遜每天齋唷八十隻蕉,而 Friday 則淨食 9.6 尾魚,他們的生活質素肯定比自給自足時還要差! 聰明的讀�穸眶M猜到他們兩人必定會以交易來改善生活。 下集會討論 why voluntary trade is always mutually beneficial!再見!在此可點選以下的按鈕重溫 Adam Smith's Principle of Absolute Advantage。
Adam Smith:Division of labour and the principle of absolute advantage 阿當˙史密斯 (Adam Smith) 提出絕對優勢定律 (principle of absolute advantage) :
Adam Smith:Division of labour and the principle of absolute advantage A country should specialise in producing the good which it has an absolute advantage and export it to the other, and import the good which it has an disadvantage. As a result, total world's output increases and both countries can gain.
