問題:Suppose two goods x and y are being produced efficiently and that
the production of x is always more labor intensive than the production of
y. Production depends only on two factors (capital and labor)these may be
smoothly substituted for each other.The total quantities of these inputs
are fixed.An increase in the production of x and a decrease in the production
of y will

a)increase the capital-labor ratio in each firm
b)decrease the capital-labor ratio in each firm
c)leave the capital-labor ratio for each firm unchanged
d)increase the capital-labor ratio in y and decrease the capital-labor
ratio in x

我的想法:

解答給的是A

但是我覺得既然X是勞動多用

那當x多生產時 L不是會上升嗎?

相對Y少生產時就是K下降阿

那capitaal-labor ratio= K/L


不就兩家廠商的K/L值都會下降嗎?

是我哪裡看錯了呢?

還是解答的問題?

麻煩大家了!

thx~
