Adam Smith is often regarded as the father of modern economics. His groundbreaking work, "The Wealth of Nations", was published in 1776. In this work, Smith introduced the concept of the invisible hand, which suggests that individuals, pursuing their own self-interest, unintentionally contribute to the economic well-being of society. His ideas on free markets, competition, and the division of labor laid the foundation for classical economic thought.
John Maynard Keynes profoundly impacted economic theory with several significant works. His first major contribution was "The Economic Consequences of the Peace" (1919), in which he critiqued the Treaty of Versailles and its economic implications for Europe post-World War I. In "The General Theory of Employment, Interest, and Money" (1936), Keynes introduced ideas that reshaped macroeconomic thought, emphasizing the importance of aggregate demand in determining national income and advocating for government intervention to manage economic downturns.
