ABSTRACT
This book is about the assessment of profitability when investment is undertaken in either or both mechanizing production and expanding the scale of production to take advantage of economies of scale. This book introduces, and presents the case for, a new concept of profitability assessment, here called the ‘efficiency rate of profit’, to be used in this assessment of profitability. As part of this argument, this book also considers, and resolves, the question of interest as a cost.
