像是長期的菲利普曲線,賴景昌老師的定義是
(dP/P)=B(Un-U)+(dP/P)*
但像我補班的教材(高昇)則把其定義為
(dP/P)=f(Un-U)+B(dP/P)*
===========================================
像是第一式有指出當(dP/P)=(dP/P)*
則Un=U,但文中似乎沒有交代B會怎麼變化??
而第二式高昇是把B當成是預期的程度來討論長期菲利普曲線
的斜率!!
(前面幾句有點題外....)
我的意思是說為什麼兩個公式會有如此差別??
那一個才是對的呢?
因為我發現假如當做法則與權衡的題目,結果好像會有差別。
============================================
Un=自然失業率
(dP/P)*=預期物澎率
B表BETA,像某係數這樣。
