🔄 The Barter System
↑ Back to Top
🔄Barter System = exchanging goods/services for other goods/services — without using money
✏️Example: You have extra eraser → classmate has extra pencil → swap! That's barter!
🌾Ancient people: farmer gives wheat → gets pottery | shepherd gives milk → gets cloth

🌾 Ancient traders exchanging commodities
⚠️ Problems with Barter System:
❌Double coincidence of wants — both people must want exactly what the other has!
❌Hard to divide goods — how do you give half a cow for shoes?
❌Difficult to store value — food spoils, animals need feeding
❌No standard measure of value — how many apples = one pot?
