What is Microeconomics?
Every business operates in a market where consumers make choices, firms compete for customers, prices fluctuate, and resources are limited. Microeconomics is the branch of economics that studies these individual economic activities and explains how consumers, producers, and businesses interact to determine prices, production, and the efficient allocation of resources. It helps students understand the economic principles that influence everyday business decisions and market behavior.
In BBA 1st Semester, this subject introduces students to the core concepts of consumer behavior, demand and supply, production, cost analysis, market structures, factor pricing, and welfare economics. Students learn how businesses respond to changing market conditions, how prices are determined, why consumer preferences matter, and how firms maximize profits under different competitive environments. These concepts provide a strong analytical foundation for finance, marketing, business strategy, and managerial decision-making.
These notes will help you understand important topics such as:
- Introduction to Microeconomics: Understanding the nature and scope of economics, basic economic problems, production possibility curve (PPC), economic systems, and the distinction between microeconomics and macroeconomics.
- Consumer Behaviour and Demand Theory: Cardinal and ordinal utility approaches, indifference curves, consumer equilibrium, law of demand, determinants of demand, and shifts in the demand curve.
- Elasticity of Demand and Supply: Price, income, cross, and advertising elasticity of demand, elasticity of supply, market equilibrium, price ceiling, price floor, consumer surplus, and producer surplus.
- Production and Cost Theory: Production functions, law of variable proportions, returns to scale, isoquants, economies of scale, cost concepts, and short-run and long-run cost analysis.
- Market Structures: Features and price determination under perfect competition, monopoly, monopolistic competition, and oligopoly, along with concepts such as price discrimination, game theory, and market efficiency.
- Factor Pricing and Distribution Theory: Marginal productivity theory, wage determination, theories of rent, interest, profit, and the functioning of factor markets.
- Welfare Economics: Pareto optimality, market failures, externalities, public goods, information asymmetry, and government measures to improve economic welfare.
