Introduction to Microeconomics Quiz

Introduction to Microeconomics

• Microeconomics studies the behaviour of individual economic agents (consumers, firms, industries).
• It examines decision-making in markets and how decisions influence prices and quantities of goods and services.
• Key concepts include supply and demand, equilibrium, elasticity, market structures (perfect competition, monopoly, oligopoly), production, costs, and market failures.
• Microeconomics provides tools for analysing economic phenomena.

Supply and Demand

• Supply and demand are central to microeconomics.
• Supply is the amount producers are willing and able to sell at various prices over a specific time.
• Demand is the amount consumers are willing and able to buy at various prices over a specific time.
• Supply and demand interaction determines market price and quantity traded.
• Equilibrium occurs when supply equals demand.

Market Equilibrium

• Market equilibrium is where quantity supplied equals quantity demanded at a specific price.
• There's no pressure for price or quantity to change at equilibrium.
• Any deviation from equilibrium triggers market forces to restore it.

Elasticity

• Elasticity measures responsiveness of one variable to changes in another.
• Price elasticity of demand measures percentage change in quantity demanded due to a percentage change in price.
• Price elasticity of supply measures the percentage change in quantity supplied due to a percentage change in price.
• Income elasticity gauges quantity demanded change due to consumer income changes.
• Cross-price elasticity shows how quantity demanded of one good changes due to another good's price change.

Market Structures

• Market structures describe market characteristics like the number of firms, product type, and entry/exit ease.
• Perfect competition features many buyers/sellers, homogeneous products, free entry/exit, and perfect information.
• Monopoly has a single seller of a unique product.
• Oligopoly involves a few large firms dominating the market.

Production and Costs

• Production transforms inputs (labour, capital, land) to outputs (goods/services).
• Cost is the expenditure in the production process.
• Short-run costs include variable costs (e.g., labor) and fixed costs (e.g., rent).
• Long-run costs encompass all adjustable costs.
• Production functions describe the relationship between inputs and output.

Market Failure

• Market failure happens when the market doesn't allocate resources efficiently.
• Causes include externalities, public goods, imperfect information, and monopolies.
• Externalities are costs or benefits imposed on third parties.
• Public goods are non-excludable and non-rivalrous.
• Imperfect information occurs when buyers/sellers have incomplete or inaccurate market/product knowledge.

Consumer Behavior

• Consumer behavior examines purchasing decisions (what, how much, when).
• Utility theory and concepts like indifference curves and budget constraints are used here.
• Consumer preferences and rationality are commonly assumed, though behavioral economics challenges this.

Firm Behavior

• Firm behavior analyses profit-maximizing decisions on production, pricing, and output.
• This involves production factor choices and cost minimization.
• Firms in different market structures (perfect competition, monopoly) face different challenges/opportunities.

Conclusion

• Microeconomics frames individual agent decision-making and its market impact.
• Tools like supply and demand, elasticity, and cost analysis help analyse real-world economics and inform policy decisions.
