ABSTRACT
We have so far discussed models of a one-product competitive growing economy on the assumptions that the rate and nature of technical progress, the growth rates of the population, and the savings ratios were all given and constant. But this is, of course, not so. Each of these quantities may itself be much affected by economic developments; and accordingly in this and the following chapters (Chapters X to XIV) we shall consider the way in which economic changes may themselves affect these three basic determinants of economic growth.
