沒有權限在Stock版PO文,可以請有權限的人幫轉股版嗎?謝謝:)
--以下正文--
據說跟鄉民認真的話就輸了,不過還是不小心認真了。
回到遠古以物易物的時代,假設俺是種田的,專種小麥,
有一天,我需要一個新的農具,我只好去城裡挨家挨戶找需要小麥的鐵匠,
然後跟它談定交易,假設談好價格,一公斤小麥換一個鋤頭。麥鋤兩訖,皆大歡喜。
到這裡為止。還是原PO認定的全套交易
小麥,工作機會
-------------------->
農夫 鐵匠
<-------------------
鋤頭,工作機會
不過 農夫後來發現自己的產品在城裡不太容易變現,
大家常常年頭小麥一買一百斤吃到然後吃到年底,所以常常找買主找到地老天荒。
經過觀察之後,農夫發現酪農的產品不太一樣,大家也一樣要常常吃牛奶,
不過牛奶不耐放,大家一次只能換一兩斤,吃完再去找酪農換,因此酪農要換東西很好換。
(以行話來說,牛奶的流動性較佳)
發現這件事情之後,農夫決定去找酪農,跟他談定,以一百斤的小麥換他一百斤的牛奶,
但是他的牛奶不會一次領回,而是有需要的時候再去找他拿。
到目前為止,也還是原PO認定的全套交易。
小麥,工作機會
-------------------->
農夫 酪農
<-------------------
牛奶,工作機會
不過之後農夫的生活就變得很愉快了,下次他又需要新的鋤頭的時候,
他就先去找酪農把麥換成牛奶,再拿牛奶去換鋤頭,因為牛奶大家每天都喝,
所以隨便找一個鐵匠都可以換的到。目前為止,還是全套交易。這應該沒有疑問吧?
(農夫不工作,就沒有小麥換牛奶,那就沒有牛奶換鋤頭,所以鐵匠收了牛奶,
就是給了農夫工作機會)
鋤頭,工作機會 小麥,工作機會
---------------> -------------------->
鐵匠 農夫 酪農
<-------------- <-------------------
牛奶,工作機會 牛奶,工作機會
然後我們把牛奶換成金幣,酪農換成金匠。
鋤頭,工作機會 小麥,工作機會
---------------> -------------------->
鐵匠 農夫 金匠
<-------------- <-------------------
金幣,工作機會 金幣,工作機會
(農夫不工作,就沒有小麥換金幣,就沒有金幣換鋤頭,所以鐵匠收了金幣,
就是給了農夫工作機會)
這有什麼疑問嗎?
所以原PO假設的前提:『半套交易』是不存在的,後面就不用討論了。
