Critically evaluate scenarios in the free econ quiz to reinforce understanding of supply-demand equilibrium and market adjustments.
Cheat Sheet
- Law of Demand -
The law of demand states that higher prices lead to lower quantities demanded, forming a downward-sloping demand curve (Mankiw, 2018). Recall "DIME" as a mnemonic: Demand Inverse - price ↑ causes demand ↓, and vice versa. Try plotting P=$10 to $7 and observing Qd changes to reinforce the concept (Khan Academy).
- Law of Supply -
According to the law of supply, producers offer more goods at higher prices, resulting in an upward-sloping supply curve (Investopedia, 2020). Use "SPUD" (Supply Positive Upward Direction) to remember that price ↑ leads to quantity supplied ↑. For example, simulate P from $2 to $4 in a basic supply schedule to see Qs rise from 50 to 120 units.
- Market Equilibrium -
Equilibrium occurs where quantity supplied equals quantity demanded, determining the market-clearing price and quantity (University of Illinois, 2019). Solve algebraically by setting Qd = a - bP and Qs = c+dP to find P* and Q* (e.g., 100 - 2P = 20+3P yields P* = 16, Q* = 68). Graph both curves to visualize how excess supply or demand moves the price toward equilibrium.
- Shifts vs. Movements -
Recognize that price changes cause movements along curves, while non-price factors (income, tastes, input costs) shift the entire demand or supply curve (CORE Econ, 2021). For instance, an income rise shifts normal goods' demand curve to the right, increasing Qd at every price. Create flashcards of major shifters - TRIBE for demand (Tastes, Related goods, Income, Buyers, Expectations).
- Price Elasticity of Demand -
Elasticity measures responsiveness: PED = |%ΔQd / %ΔP|, with elastic (PED > 1) or inelastic (PED < 1) demand (NBER Working Paper, 2017). Practice the midpoint formula: ((Q2 - Q1)/[(Q2+Q1)/2]) / ((P2 - P1)/[(P2+P1)/2]) to avoid bias. Remember "Elastic East Bound" to recall that elastic demand curves are flatter.
