First published in 1968, this is the second part of Professor Meade’s Principles of Political Economy, which presents a systematic treatment of the whole field of economic analysis in the form of a series of simplified models which are specifically designed to show the interconnections between the various specialist fields of economic theory. In this volume, Professor Meade is concerned with the theory of economic growth and the rates at which various economic quantities are growing. In order to do this, he introduces capital goods into the system and allows for growth through capital accumulation, population expansion and technical progress. His analysis is divided into two models: a one product model and a many-product model.
