Alfred Marshall was a pioneer in economics, even by today’s standards. In 1890 he published Principles of Economics which, compiled from years of study and contemplation, proved to be his magnum opus on economic thought. The work was so fastidiously compiled that it served as a standard in which all economic thought over the next century would respectfully consider. This essay will delve into the concept and history of the growth in wealth. A brief outline of Marshall’s descriptive analysis of wealth accumulation will provide a basic framework that can be used for comparing Marshall’s thoughts to that of other economists.
