Correct Answer:
Option B —
marginal returns
Understanding Ricardo’s LawDavid Ricardo, a classical economist, applied the Law of Diminishing Marginal Returns primarily to agriculture.
The Principle: As more units of a variable factor (like labor or capital) are added to a fixed factor (like a specific plot of land), the additional output generated by each new unit will eventually decrease.
Why it Happens: Ricardo argued that since the supply of fertile land is fixed, as a population grows, farmers are forced to either:
Cultivate the same land more intensely (Intensive Margin).
Move to less fertile "marginal" land (Extensive Margin).
The Result: In both cases, the cost of producing an extra unit of grain increases because the marginal productivity of the inputs decreases.
