Markets, Prices and Competition
How markets and competition work
Prices are a signalling system. They carry information about scarcity and desire that no central planner could collect, which is the strongest argument for markets.
The unit covers what a market is, how prices guide choices, competition, monopoly, and price controls.
This unit breaks down into 23 short steps and 119 questions, starting at difficulty 1 and building to 5. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
