| Question | Answer |
|---|---|
| Changes in Equilibrium Step 1 | Sketch Supply and Demand Diagram BEFORE event |
| Changes in Equilibrium Step 2 | decide whether the event will affect supply OR demand |
| Changes in Equilibrium Step 3 | decide whether effect on supply or demand is negative or positive |
| Changes in Equilibrium Step 4 | Compare new equilibrium price + quantity to original ones |
| demand curve | relationship between quantity demanded and price in given market on a graph |
| supply curve | relationship between the quantity supplied at price in given market on a graph. |
| Equilibrium | Occurs when the supply and demand curves cross on the graph |
| Surplus | Price of quantity supplied is MORE than quantity demanded. Economic pressures will push back towards equilibrium. |
| Shortage | Price of quantity supplied is LESS than the quantity demanded. Economic pressures will push back towards equilibrium. |
| Ceteris Paribus | Assuming other factors do not change in any given event. |
| changes in taste, population, income, prices of substitute or complement goods, expectations about future conditions/prices. | Factors that shift DEMAND curve |
| input prices, natural conditions, changes in technology, and government taxes, regulations, or subsidies. | Factors that shift SUPPLY curve |
| Price ceiling | Prices prevented from rising ABOVE a certain level, if set below equilibrium price - shortage will occur. |
| Price floor | Prices prevented from falling BELOW a certain level, if set above equilibrium price - excess will occur. |
| Deadweight loss | loss in surplus that occurs when economy creates inefficient quantity |
| Social surplus | Consumer surplus + producer surplus |
| Producer surplus | gap between price producers will sell a product (cost basis) and the current market equilibrium price |
| Consumer surplus | gap between price consumers will pay (preference basis) and the current market equilibrium price |
