Did Ricardo reject the concept of labor theory of value?

David Ricardo did not reject the labor theory of value; rather, he refined it. He argued that the value of a commodity is determined by the amount of labor required to produce it, but he also acknowledged that other factors, such as capital and land, influence production costs. Ricardo's contributions helped to differentiate between value and price, emphasizing that while labor is a key factor in determining value, market prices can fluctuate due to supply and demand dynamics. Thus, he maintained a version of the labor theory of value while expanding its application.
