CHAPTER 00 / EMPTY LAND

The City of Choices

An economy begins on a small grid: limited land, limited time, unlimited wants. Scroll through this pixel city to see how choices turn into prices, banks, factories, ports, and exchanges.

Economics studies how people allocate scarcity. Every building in this city is a decision: what to make, what to save, where to work, and who to trade with.

CHAPTER 01 / THE MARKET

The Market Finds a Price

At the street stalls, buyers express demand and sellers reveal supply. The posted price moves until plans meet.

CHAPTER 02 / THE BANK

Money Sets the Tempo

A central bank adjusts the interest rate. Lower rates invite cranes and loans; higher rates slow new construction so prices can cool.

CHAPTER 03 / THE FACTORY

Productivity Multiplies Output

Factories turn land, labor, and capital into goods. When productivity rises, the same resources produce more blocks per day.

OUTPUT SPEED: 3X
CHAPTER 04 / THE PORT

Trade Connects Specialties

Ports let cities exchange what they make best. Comparative advantage means both sides can gain, even when one side is more efficient at everything.

COMPLETE CITY / DAY'S END

The Machine Is Human

Economics is not a spreadsheet floating above life. It is the city itself: stalls, banks, factories, ports, exchanges, wages, prices, and choices moving in one visible system.

Tomorrow, the grid begins again.
