Understanding Microeconomic Market Dynamics

From the study guide

Supply and Demand Dynamics Revision Sheet

1. 📌 Essentials

  • Demand: Quantity consumers are willing to buy at prices; slopes downward.
  • Supply Quantity producers are willing to sell at various prices; slopes upward.
  • Price Elasticity of Demand (PED): Measures how much QD responds to price changes.
  • Elastic demand: PED > 1; small price change causes large QD change.
  • Inelastic demand: PED < 1; QD less responsive to price.
  • Unitarity: PED = 1; proportional change in QD to price change.
  • Perfectly inelastic: PED = 0; QD unchanged regardless of price.
  • Perfectly elastic: PED approaches infinity; QD drops to zero if price changes.
  • Income elasticity: Response of demand to income changes; positive for normal goods, negative for inferior.
  • Market response: Demand/supply shifts based on price, income, advertising, and policies.
