Microeconomics focuses on how individual households, firms, and industries make decisions to allocate limited resources. It examines key concepts such as supply and demand, where the price influences both the quantity supplied and demanded, leading to market equilibrium. Elasticity measures how sensitive demand and supply are to changes in price or income. Consumer behavior is analyzed through utility theory, exploring how individuals maximize satisfaction, while producer behavior focuses on cost structures, including fixed and variable costs, and economies of scale. The study of market structures covers perfect competition, monopolies, monopolistic competition, and oligopolies, highlighting their characteristics, pricing power, and barriers to entry. Factor markets, such as labor and capital, determine wages and interest rates based on supply and demand. Microeconomics also addresses market failures, including externalities like pollution or education, and the need for government intervention to correct inefficiencies through taxes or subsidies. Welfare economics looks at consumer and producer surplus, and deadweight loss from market distortions, while income distribution and inequality are measured using tools like the Lorenz Curve and Gini Coefficient. Finally, asymmetric information can lead to market failures, with issues like adverse selection and moral hazard, where one party has more information than the other, influencing transaction outcomes.
