內容介紹
內容提要作者寫作本書的目的在於和讀者分享他本人過去20年在巨觀經濟
學研究工作中的收穫,並幫助讀者建立起關於總量經濟學的觀念和意
識。和其他總量經濟學教科書相比,本書包含了一些其他教科書未論
及的問題,如預期理論、現代經濟學的開放性等。而且本書經常在多
個層面上進行理論和實際的比較,引用了較多熔深度和趣味性於一爐
的實例。
作者以一個重要模型貫穿全書,其核心是商品市場、金融市場和
勞動市場的均衡條件。本書首先介紹IS-LM短期經濟模型,討論商品
市場和金融市場的均衡,並把對經濟的預期在巨觀經濟決策方面的作
用和增強現代經濟開放性的重要性作為其中的兩個主題。接著在中長
期理論中,介紹勞動市場均衡、總供給與總需求模型,分析高失業率
和高通貨膨脹率時期的特點,以及經濟成長中資本積累和技術進步的
作用。最後,讀者可用前面章節中學到的方法去分析當今世界最重要
的幾個經濟問題,回顧總量經濟學在過去50年中的演進過程,巨觀
經濟政策的作用及其所受到的限制,以及當前的研究方向。
本書既可作為經濟管理專業本科生和研究生的教學用書,也可供
其他經濟工作者參考。
