本書著重講解如何構建模型、如何求解經濟主體優(yōu)化問題、理解模型的經濟學含義、如何分析模型動態(tài)特征等，除此之外，本書還會介紹Dynare工具箱，并詳細講解如何使用Dynare獲得模型數(shù)值解，并通過解析解和數(shù)值解的對比，讓讀者理解通過Dynare獲得的數(shù)值解的含義。希望通過本書的出版降低宏觀經濟學研究的門檻。全書可以分為五個部分。第一部分為引言，目的在于厘清宏觀經濟學的研究范式和研究內容，以及動態(tài)隨機一般均衡模型與宏觀經濟學研究的關系，并介紹DSGE模型求解過程中使用到的Matlab軟件和Dynare工具箱。第二部分是實際經濟周期（RBC）模型，旨在通過簡單的RBC模型講解DSGE模型的模型構建、模型求解和模型分析范式，厘清以生產率沖擊為代表的經濟沖擊的傳導渠道。第三部分是新凱恩斯模型，即在RBC模型的基礎上引入名義黏性，包括價格黏性和名義工資黏性，旨在明確引入名義黏性后經濟沖擊傳導渠道的變化及對經濟的影響。第四部分是新開放宏觀經濟學模型，將封閉經濟模型擴展到開放經濟模型，包括對稱兩國模型、非對稱兩國模型和小國模型，旨在厘清經濟沖擊傳導渠道的變化以及經濟波動的跨國傳導渠道。第五部分是專題系列，包括福利專題和金融摩擦專題，福利專題講述了現(xiàn)有研究中常用的測度社會福利的方法的準確性和存在的問題，金融摩擦專題講述了抵押融資約束在房地產模型和一般模型中的應用。
