最近經濟老師給了我們一個題目 不太會做 希望有人可以幫我...
The practice of open grazing in the Western United States was discovered when cattlemen let
their cattle loose during the civil war during their absence. On returning to the ranch many
discovered that their cattle had gained more weight on the open range than they had on closed
fields. Does this accidental discovery of a new ranching method mean that the farmers were
not maximizing their wealth before the discovery? ( 抱歉 ...不會翻譯)
不知道哪為大大可以教一下...
