: has been equal to the natural rate of umemployment for a number of years.
: Given this information , we know that ：
: A.the rate of inflation should neither increase nor decrease
: B.the rate of inflation will approximately be equal to zero

: 想法：直覺是想到菲律浦曲線，不過不曉得該怎麼解答...


應該是使用調整菲利浦曲線(adjusted phillips curve)

該模型說明：

當失業率為自然失業率的時候

代表物價變動率為0
^^^^^^^^^^
那物價變動率為0，則通膨率不變(假設其他條件不變之下)

所以答案應該是A




: 43.For this question , assume that there are decreasing returns to capital,
: decreasing returns to labor , and constant returns to scale. An increase
: in the capital stock will cause which of the following ?
: A.not change in output
: B.an increase in output per capita
: C.a reduction in output
: D.derease the capital-labor ratio
: 想法：直覺是(B), decreasing returns to capital 是什麼意思 ? 報酬遞減 ?
: 謝謝各位 !!


那句話是這樣翻譯應該沒錯

計算規模報酬是在勞動與資本"皆"增加固定比例後才能計算

這邊只說增加資本

資本投入增加，產出也增加

但勞動沒變

所以每人(每位勞工)的產出增加了
