Abstract:        
This paper is concerned with the meaning and validity of the 'Ricardo effect'.  
It is shown that the machinery substitution effect contemplated by David Ricardo  
(a) is not caused by a rise in the real wage rate, (b) is independent of the  
so-called 'price effect', and (c) presupposes very special assumptions about the  
available set of production methods. The paper also investigates whether  
Ricardo's machinery substitution argument anticipates the principle of factor  
substitution with regard to capital and labour in marginalist theory.
