The supreme merit of this paper lies in the elegance of the mathematical solution of a highly generalised problem in theoretical economics. But the paper is of considerable interest to economists as well as to mathematicians, because it deals simultaneously with questions on several fields of economics, which until this paper was first read, (in 1932) had seldom been considered together as parts

At the same time he demonstrates the mechanism which determines the rate of interest and the rate of expansion of the whole economy.
