ABSTRACT
Akerman took a long step forward in the development of that branch of capital and interest theory with which we are here concerned by expounding his own theory in terms of durable goods, the most important form of capital goods. But since his book 1, which consists mainly of numerical calculations, is one of the most laborious in economic literature, it is no wonder that his contribution has attracted little attention and exerted hardly any influence. I t is not easy to give an adequate account of the contents of a book of this character, but I do hope that the following treatment of Akerman's work will make his method and conclusions understandable.
