Economics

How money, choices, and the whole economy work - from needs and wants and saving your first coins, to supply and demand, markets, banking, trade, and university macroeconomics, one tiny step at a time.

Economics covers supply and demand, money, markets, trade, work, inflation, taxation, growth, inequality and the role of governments and central banks.

The early units deal with things you already encounter: prices, wages, saving and spending. The later ones move to the whole-economy view, where the same intuitions often stop working and need replacing with something more careful.

Economics is the study of choice under scarcity, which is most decisions. It is also the subject most often invoked in political argument by people using its vocabulary without its reasoning.

Study guide · 8 min readHow to Learn EconomicsEconomics is not about money, and treating it as though it is makes the whole subject harder. A guide to thinking at the margin, why supply and demand gets misapplied constantly, and how to tell the model from the world.

What you will be able to do

Explain what opportunity cost is and apply it to your own time
Say what shifts a supply curve as opposed to moving along it
Explain why two countries both gain from trade even when one is better at everything
Say what GDP measures and what it ignores

The thing people get wrong

That economics is about money. Money is a measuring device; the subject is about trade-offs, and most of its conclusions would still hold in an economy that had never invented currency.

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.
