《经济动力学导论》为学生提供了一个框架,帮助他们理解和领会经济模型背后的基本直觉,并使用 MATLAB® 中的模拟技术对这些模型进行实验。
本书超越了其他经济模型教材通常有限的范围,这些教材主要侧重于阐明静态均衡模型。比较静态分析会阻止学生询问如何从最初的非均衡位置实现均衡位置,并限制他们对此类分析背后的动态的理解。本书向读者介绍了十个成熟的宏观经济模型 - 包括凯恩斯乘数模型、萨缪尔森乘数和索洛增长模型 - 并引导读者了解每个模型背后的动态系统。每一章都以概述该模型旨在帮助解决的经济问题开始,然后解释该模型的数学原理。使用 MATLAB® 中的模拟和可视化技术提供解决方案,这些技术与分析有机交织在一起,并以循序渐进的方式介绍,以引导读者完成整个过程。附录提供了 MATLAB® 的介绍以及所有必要的代码。
本书非常适合经济动力学、宏观经济建模和计算经济学课程,以及对经济模型感兴趣的金融、数学和工程专业的学生。

Index
An Introduction to Economic Dynamics provides a framework for students to appreciate and understand the basic intuition behind economic models and to experiment with those models using simulation techniques in MATLAB®.
This book goes beyond the often-limited scope of other texts on economic models, which have largely focused on elucidating static equilibrium models. Comparative static analysis inhibits students from asking how the equilibrium position is achieved from an initial out-of-equilibrium position and limits their understanding of the dynamics that underlie such analysis. In this textbook, readers are introduced to ten well-established macroeconomic models – including Keynesian multiplier models, Samuelson’s multiplier and Solow’s growth model – and guided through the dynamical systems behind each model. Every chapter begins with an overview of the economic problem which the model is designed to help solve followed by an explanation of the mathematics of the model. Solutions are provided using simulation and visualisation techniques in MATLAB®, which are interwoven organically with the analysis and are introduced in a step-by-step fashion to guide the reader along the way. Appendices provide an introduction to MATLAB® along with all the necessary codes.
The book is ideally suited for courses in economic dynamics, macroeconomic modelling and computational economics, as well as for students of finance, mathematics and engineering who are interested in economic models.
