This project simulates a small virtual economy where entities work, manufacture, trade, and pay taxes, all in pursuit of a better quality of life. The system is built with an Entity-Component-System (ECS) architecture to make behavior extensible and modular.
In this simulation:
- Entities represent economic agents such as individuals and banks.
- They produce, trade, buy, and sell materials.
- Each entity aims to maximize its quality of life, calculated as the sum of the logarithms of its material quantities.
- Entities pay taxes to banks and operate under simple economic rules.
- A visualization allows you to watch the economy evolve over time.
-
Quality of Life:
QoL = Σ log(material_quantity + 1) -
Trading Logic:
Buyers choose which resource to buy based on which one will increase their quality of life (QoL) the most, or based on the resources they need to manufacture something new.Sellers offer only one resource for sale which is the one whose loss will reduce their QoL the least. However, if all of a seller’s resources are of equal quantity, they will not be willing to sell anything that day.
-
Taxes:
A portion of each transaction is collected as tax by the bank which is paid by the seller of that transaction. -
Entity-Component-System (ECS):
Each entity is composed of reusable components (e.g., Inventory, SkilledWorker, UnskilledWorker), and systems process behavior for all relevant entities.
