(B) Karl Marx
Explanation:
David Ricardo's theories on wages (Iron Law of Wages) and rent (Theory of Economic Rent) significantly influenced Karl Marx's economic thought, particularly his:
a. Labor theory of value (adapted from Ricardo)
b. Analysis of class struggle (capitalists vs. workers)
c. Concept of surplus value (linked to Ricardo’s rent theory)
Information Booster :
(A) Adam Smith
Smith was Ricardo's predecessor (wrote Wealth of Nations in 1776, before Ricardo's work)
Ricardo actually built upon and modified Smith's ideas, not the other way around
Smith's wage theory was more optimistic than Ricardo's "Iron Law"
(C) J.S. Mill
While Mill was influenced by Ricardo generally, his focus was different:
Mill incorporated more social reform elements
His wage theory considered human capital and education
On rent, he followed Ricardo but didn't develop it further significantly
