如下: 在一個封閉的環境下有兩個產業分別是衣服跟鋼鐵產業 每一個成品的價格都是一塊錢 衣服的MP = 1 鋼鐵的MP = 12L(-1/2平方)-2 而勞動數量有限 L鋼鐵 + L衣服 = 25 第一題問的是 假如是一個完全競爭的勞動市場 那各個產業各會雇用多少勞動量 是用 MP衣服 / P衣服 = MP鋼鐵 / P鋼鐵 這個公式算對吧? 出來之後鋼鐵跟衣服產業是 16 跟 9 這邊應該沒什麼大礙至於第二題我就真的有問題了 (2) Suppose that workers in the steel sector form a union,which acts as a monopolist in suppling labor to the steel industry.the union chooses a level of employment that maximizes then total wages of its members.How many workers will the union allow to be employed in the steel sector?how many will now be employed in the clothing sector? What wage rate will workers in each sector receive? 應該是在問鋼鐵產業的工人想成立一個公會 然後使這個產業成為獨佔產業進而增加勞工的薪資這樣想法對嗎? 那怎麼求薪資會多多少阿... 第三小題是 if workers in clothing had unionized in order to increase their wage rate instead of workers in steel,what should have happened to employment and wages in each sector ? explain why ? 這一題說真的我也看不太懂...= = 請了解的人幫我解答一下 謝謝大家!! --
