Defining Market Surplus: Causes, Effects, and Economic Examples

📚 Understanding Market Surplus

Market surplus occurs when the quantity of a good or service supplied exceeds the quantity demanded at a given price. This typically leads to a decrease in price to clear the surplus.

• 📈 Definition: A situation where the quantity supplied is greater than the quantity demanded.
• 💸 Cause: Prices set above the equilibrium price or decreased consumer demand.
• 📉 Effect: Downward pressure on prices as suppliers try to sell excess inventory.
• 📊 Measurement: Calculated as the difference between quantity supplied and quantity demanded at a specific price: Surplus = Quantity Supplied - Quantity Demanded.
• 💡 Example: Imagine farmers produce more apples than consumers want to buy at the current price. This results in an apple surplus.
