2.1. The role of markets in allocating resources
• definition of a market • examples of markets • roles of buyers and sellers
2.2. Demand
• definition of demand • link between individual demand and market demand • drawing and interpretation of the demand diagram
• causes of extensions and contractions in demand • diagrams that illustrate movements along a demand curve
• causes of decreases and increases in demand • diagrams that illustrate shifts of a demand curve
2.3. Supply
• definition of supply • link between individual supply and market supply • drawing and interpretation of the supply diagram
• causes of extensions and contractions in supply • diagrams that illustrate movements along a supply curve
• causes of decreases and increases in supply • diagrams that illustrate shifts of a supply curve
2.4. Price determination
• how the price mechanism provides answers to the basic resource allocation decisions of what, how and for whom to produce
• equilibrium price and equilibrium quantity in a market: • definition of market equilibrium • interpretation of equilibrium using demand and supply schedules • drawing and interpretation of equilibrium using demand and supply curves
• disequilibrium prices and quantities: • definition of market disequilibrium • interpretation of disequilibrium using demand and supply schedules • drawing and interpretation of disequilibrium using demand and supply curves • shortages (demand exceeding supply) and surpluses (supply exceeding demand)
2.5. Price changes
• how price changes are caused by changes in demand and supply
• effect of price changes on sales • use of demand and supply diagrams to illustrate the impact of changes in market conditions
2.6. Price elasticity of demand (PED)
• Definition of PED
• calculation of PED using the formula • interpretation of the significance of the PED value: perfectly inelastic, inelastic, unitary, elastic, perfectly elastic • drawing and interpretation of demand curve diagrams to show different PED
• main influences on whether demand is elastic or inelastic
• effect of price changes on the amount spent by consumers and revenue raised by firms, shown both in a diagram and as a calculation • relationship between PED and the amount spent by consumers and revenue raised by firms
• implications of PED for decision-making by consumers, workers, producers/firms and government
2.7. Price elasticity of supply (PES)
2.7.1Definition of PES
• Definition of PES
2.7.2Calculation of PES
• calculation of PES using the formula • interpretation of the significance of the PES value: perfectly inelastic, inelastic, unitary, elastic, perfectly elastic • drawing and interpretation of supply curve diagrams to show different PES
2.7.3Determinants of PES
• main influences on whether supply is elastic or inelastic
2.8. Market economic system
• Definition of the market economic system
• advantages of the market economic system • disadvantages of the market economic system
2.9. Market failure
• Definition of market failure
• public goods, merit goods, demerit goods, private benefits, external benefits, social benefits, private costs, external costs, social costs, monopoly
• causes relating to public goods, merit goods, demerit goods, external costs and external benefits, abuse of monopoly power
• implications of misallocation of resources in relation to: • the over-consumption of demerit goods and goods with external costs • the under-consumption of merit goods and goods with external benefits • the non-provision of public goods • restricted supply causing higher prices under a monopoly Note: demand and supply diagrams relating to market failure are not required.
2.10. Mixed economic system
• Definition of the mixed economic system
• advantages of the mixed economic system • disadvantages of the mixed economic system
• definitions, drawing and interpretation of diagrams, advantages and disadvantages of: • maximum and minimum prices in product markets • indirect taxation • subsidies • definitions, advantages and disadvantages of: • regulation • privatisation • nationalisation • direct provision of goods and services • quotas, e.g. for the extraction of natural resources
