It is widely believed that Okishio's theorem disproved Marx's theory that the rate of profit is necessarily falling with the technological advancement.

I have read the theorem from secondary sources so far. How can I find the original source by Okishio online?

(Secondary sources cite an article but when I check that citation in Google Scholar the page redirects to another article by a different person (John E. Roemer's treatment of the theorem).

Citation: Okishio, N. (1961). Technical changes and the rate of profit. Kobe University Economic Review, 7, 85–99
