This volume presents a mathematical analysis of cumulative processes of economic growth. In continuous time, the fundamentals of economic growth models are expressed by systems of nonlinear differential equations. With homogeneous dynamic systems as the unifying mathematical framework, the long-run stability properties and the phase portraits of the solutions to classical, neoclassical and Keynesian growth models are analyzed. The general structure and the solutions of two-sector growth models are also treated, with special attention given to output composition and factor allocation issues involved in general equilibrium dynamics. Among other results, this work shows that the dynamic structures and the kinematics of prototype growth models are globally robust. The monograph is divided in two sections: (1) Basic Economic Growth Models -- An Axiomatic Approach; (2) Basic Dynamic Systems. For scholars in economics and applied mathematics; recommended as a reference book for researchers and as a supplementary graduate textbook in economics and mathematics. A familiarity with calculus, ordinary differential equations, and the basic concepts of linear algebra is assumed.

This updated and expanded book examines the fundamentals of economic growth models as expressed by dynamic systems of nonlinear differential equations. With homogeneous dynamic systems as the unifying mathematical framework, the time paths and long-run stability properties of the solutions to classical, neoclassical, and modern macroeconomic growth models are analyzed. The general structure and solutions of two-sector and multi-sector growth models are also explored, with special attention given to the evolution of output compositions and sectoral factor allocations involved in Walrasian general equilibrium dynamics. Ramsey optimal growth (saving) models with variable intertemporal substitution (non-homothetic utility) are discussed to demonstrate the ability to generate a realistic historically observed evolution of economic per capita growth rates and saving rates. The book aims to highlight how basic economic growth models can be extended widely, including international trading economies, world market prices, commodity trade patterns, and issues related to globalization, migrations, and international factor movements. It will be relevant to students and researchers interested in economic growth and trade policy.

Two central problems in the pure theory of economic growth are analysed in this monograph: 1) the dynamic laws governing the economic growth processes, 2) the kinematic and geometric properties of the set of solutions to the dynamic systems. With allegiance to rigor and the emphasis on the theoretical fundamentals of prototype mathematical growth models, the treatise is written in the theorem-proof style. To keep the exposition orderly and as smooth as possible, the economic analysis has been separated from the purely mathematical issues, and hence the monograph is organized in two books. Regarding the scope and content of the two books, an "Introduction and Over view" has been prepared to offer both motivation and a brief account. The introduc tion is especially designed to give a recapitulation of the mathematical theory and results presented in Book II, which are used as the unifying mathematical framework in the analysis and exposition of the different economic growth models in Book I. Economists would probably prefer to go directly to Book I and proceed by consult ing the mathematical theorems of Book II in confirming the economic theorems in Book I. Thereby, both the independence and interdependence of the economic and mathematical argumentations are respected.
