differential advantages of employing them. 
They are properly termed rents, according 
to the modefn use of the term, because they 
are payments for differential advantages. 
It will be observed, moreover, that the 
complexities which were involved in the case 
of land considered above when we took into 
account the different amounts of labour and 
capital that would be applied to different 
qualities of land are involved also, to some 
extent, in the case of workmen. More doses
