LESSON 1 · How the Economy Actually Works

Markets Never Sleep

Supply and demand operate every second of every day across millions of markets at once. The stock market processes billions of price signals daily, each one a tiny negotiation between a buyer and a seller.

Digital marketplaces make this visible. Watch a concert ticket on StubHub and the price moves in real time as the event approaches.

Even labor markets follow these rules. When a city booms, wages rise as employers compete for workers. When an industry shrinks, wages stall and workers must retrain or relocate. The invisible hand never stops adjusting.
