This book is a companion volume to « The Dynamics of Keynesian Monetary Growth. Macro Foundations by Chiarella & Flaschel, CUP 2000. It describes the computer package, Simulating Nonlinear Dynamics, designed to simulate the various high order macrodynamic models of that book. The package is quite general and can be applied to any well-defined continuous and discrete time dynamical system. One feature of the package is a set of powerful interactive graphical facilities. The first part of the book outlines the philosophy and mode of use of the package, the second part provides an extensive set of applications to the macrodynamic models referred to in the title. The package is downloadable from http: //www.business.uts.edu.au./finance/staff/carl.html. Contents: SND: A Tool for the Analysis of High Order Dynamic Macrosystems - Tobin, Keynes-Wicksell, IS-LM, Keynes-Kaldor and Keynes-Metzler Models of Monetary Growth - The SND Menu Structure and the Start-Up Guides.
