Economics

The study of how societies use scarce resources — how prices form, how markets coordinate millions of decisions, how money and policy steer whole economies, and how nations trade. Nineteen chapters spanning a full learning ladder, from kindergarten to college — each built from first principles to mastery, with real diagrams, real numbers, and real reasoning.

Nineteen chapters, kindergarten to college.

A full learning ladder in one subject: start with wants and needs at age four, and finish with econometrics at university level. Each chapter stands alone but the sequence is deliberate.

Stage 1 of 5

Kindergarten — first ideas about wanting and having

For our youngest learners: simple words, real objects, and hands-on play with the very first ideas in economics.

In a nutshell

You can't have every toy you want, so you and your family choose what matters most first.

Your $10 Needs — 70% ($7) food, home, clothes, care Wants — 30% ($3) toys, treats, games
If you have $10, needs usually come first — the rest can go toward something you want.
Stage 2 of 5

Primary — money, jobs and trading in everyday life

Building on the basics with saving, earning and swapping — the everyday economics of a curious 7-to-10-year-old.

In a nutshell

Money keeps moving in a loop: people work to earn it, then spend it, which pays someone else to work.

You (a worker) Shop (a business) Work you do → ← Money you earn (and spend)
You work for the shop, the shop pays you money, and that money goes right back into buying things — a little circle of income.
Stage 3 of 5

Middle School — the first real models

Scarcity, supply and demand, elasticity and markets: the core toolkit of economic reasoning, built from first principles.

In a nutshell

Prices are the tug-of-war between buyers and sellers, and wherever supply and demand cross sets the price everyone pays.

Supply Demand P* Q* Price Quantity
Wherever the supply and demand lines cross marks the market price and quantity that balance buyers and sellers.
Stage 4 of 5

High School — firms, workers and the whole economy

Market structures, labour, and the macro dashboard — deeper models with real algebra and real-world stakes.

In a nutshell

Households and firms trade goods and labour for money in a constant loop, and that loop is what GDP measures.

PRODUCT MARKET Households (you & your family) Firms (businesses) Goods & services Spending ($) Labour, land & capital Wages, rent & profit ($) FACTOR MARKET
Households and firms trade goods and money one way, and labour and wages the other — the circular flow of income.
Stage 5 of 5

College — rigorous theory for the whole economy and beyond

Formal optimization, strategic behaviour, macro models and the statistical tools economists use to test them all.

In a nutshell

Formal models and statistics let economists turn a hunch like "prices keep rising" into a testable, precise theory.

Yr 1 Yr 2 Yr 3 Yr 4 Yr 5 Yr 6 CPI Time (years)
A steadily rising price index like this is inflation — the statistical tools of this stage let economists measure and test exactly how fast, and why.
