Step 1: Understanding the Concept:
David Ricardo was an influential 19th-century British classical economist.
He made significant contributions to classical economic theory, particularly regarding international trade and resource allocation.
Step 2: Detailed Explanation:
David Ricardo is highly celebrated in economic history for introducing the Theory of Comparative Advantage in his 1817 work, Principles of Political Economy and Taxation.
This theory argues that countries should specialize in producing and exporting goods for which they have a lower relative opportunity cost compared to other nations, even if one country has an absolute advantage in producing all goods.
By specializing and engaging in free trade based on comparative advantage, all trading partners can achieve higher levels of consumption and economic efficiency.
Let us differentiate this from other options for clarity:
- The Theory of Absolute Advantage was proposed by Adam Smith in his 1776 book, The Wealth of Nations.
- Capital-intensive modes of production are associated with modern industrial economics and the Heckscher-Ohlin model rather than Ricardo's initial classical model.
- "Slavonic approaches to trade" is not a standard classical economic theory associated with Ricardo.
Step 3: Final Answer:
David Ricardo is most well-recognized for his Theory of comparative advantage (Option C).
