Is it possible that capital, under stationary conditions and neutral time preferences, can be a permanent source of income, that is to say can a positive rate of interest exist in a stationary state?

(cp. Wicksell 1934, pp. 146, 154)

Wicksell does not give a formal or an explicit solution to the problem but he gives bits and pieces as an answer. Our purpose is to use these fragments as a basis for the construction of a formal solution, which should be located within a Wicksellian framework.
