Economies are constantly in flux, and economists have long sought reliable means of analyzing their dynamic properties. This book aims to provide a succinct and accessible exposition of modern dynamic (or intertemporal) macroeconomics. The authors use a microeconomics-based general equilibrium framework, specifically the overlapping generations model, which assumes that in every period there are two generations which overlap. This model allows the authors to describe economies over time and to employ traditional welfare analysis to judge the effects of various policies. By choosing to keep the mathematical level simple and to use the same modelling framework throughout, the authors are able to address many subtle economic issues. They analyze savings, social security systems, the determination of interest rates and asset prices for different types of assets, Ricardian equivalence, business cycles, chaos theory, investment, growth, and a variety of monetary phenomena. Each result is illustrated with analytical derivations, graphically, and by worked-out examples. Exercises, which are strategically placed, are an integral part of the book.

經濟是不斷變化的，和經濟學傢長期以來都在尋找自己的動力特性分析的可靠手段。這本書的目的是提供一個現代化的動態（或跨）宏觀經濟簡潔，方便的闡述。作者使用一個微觀經濟學的一般均衡的框架內，特彆是世代交疊模型，假設在每個時期有兩代人的重疊。這種模式使作者可以描述隨時間效益，並聘請傳統的福利分析判斷各種政策的影響。通過選擇保持簡單的數學水平，並使用相同的模型框架各地，作者能夠解決許多微妙的經濟問題。他們分析儲蓄，社會保障製度，對利率和資産，不同類型的資産價格的決心李嘉圖等價，商業周期，混沌理論，投資，經濟增長，以及各種貨幣現象。每個結果是說明與分析推導，圖形，以及製定齣的例子。演習，這是戰略性部署，是該書的一個組成部分。
