Economics & Finance

The forces that shape markets, wealth, and inequality — from supply and demand to compound interest and speculative bubbles.

Economics studies how societies allocate scarce resources. From Adam Smith's 'invisible hand' (1776) to modern monetary theory, the discipline provides frameworks for understanding markets, prices, growth, and inequality. Its mathematical models — supply-demand equilibrium, compound growth, and game-theoretic interactions — reveal the emergent patterns of billions of individual decisions.

Financial mathematics adds another layer: the power of compound interest ('the eighth wonder of the world,' attributed to Einstein), the dynamics of speculative bubbles, and the measurement of inequality through indices like the Gini coefficient. These tools are essential for understanding personal wealth, market crashes, and global inequality.

These simulations let you manipulate fundamental economic models: watch prices emerge from supply and demand, see how compound interest creates exponential wealth, observe the anatomy of market bubbles, and measure inequality with the Lorenz curve.
