High School Business: Market Surplus Study Guide & Questions

📚 Quick Study Guide

• 📈 Definition: Market surplus occurs when the quantity supplied of a good or service exceeds the quantity demanded at a given price. Think of it like having too much of something!
• 💲 Price Impact: A surplus typically leads to a decrease in price as sellers try to get rid of excess inventory.
• ⚖️ Equilibrium: Surplus indicates that the current market price is above the equilibrium price (the price where supply and demand are balanced).
• 📐 Calculating Surplus: Surplus can be visually represented and estimated on a supply and demand graph. It's the area between the supply curve, the market price, and the quantity supplied.
• 💡 Formula for Producer Surplus (related concept): Producer Surplus = Total Revenue - Total Variable Costs.
• ⏰ Causes: Surpluses can be caused by government intervention (like price floors), overproduction, or a decrease in demand.
• 🎯 Consequences: Persistent surpluses can lead to wasted resources, storage costs, and ultimately, lower profits for producers.
