Lecture I

Supply &
Demand

The invisible choreography of markets — where the desires of millions converge into a single price point. When supply meets demand, equilibrium emerges not by design but by the aggregate whisper of individual choices.

— Alfred Marshall, Principles of Economics, 1890

Lecture II

Opportunity
Cost

Every choice carries a shadow — the road not taken. The true cost of anything is the value of the next best alternative forgone. Economics begins the moment scarcity forces a decision.

— Friedrich von Wieser, Theorie der gesellschaftlichen Wirtschaft, 1914

Lecture III

Comparative
Advantage

Nations trade not because one is better at everything, but because each is relatively better at something. David Ricardo's elegant insight: specialization and exchange make all parties richer, even the less efficient ones.

— David Ricardo, On the Principles of Political Economy and Taxation, 1817

Lecture IV

The Invisible
Hand

Self-interest, channeled through competitive markets, produces outcomes no individual intended but from which all benefit. Adam Smith's metaphor endures because it captures a profound paradox: private vice yields public virtue.

— Adam Smith, The Wealth of Nations, 1776

Self-organizing market equilibrium
Lecture V

Creative
Destruction

Capitalism is, by nature, a process of creative destruction — the incessant revolution of economic structure from within, destroying the old, creating the new. Innovation is the essential fact about capitalism.

— Joseph Schumpeter, Capitalism, Socialism and Democracy, 1942
