Principles of Microeconomics

This introductory lecture establishes the foundational principles of microeconomics, defining its scope and rigorously developing the core concepts of supply and demand to analyze market mechanisms.

This lecture introduces the foundational concepts of consumer preferences and utility functions within microeconomic theory. It develops indifference curves, their properties, and the crucial relationship between marginal utility and the marginal rate of substitution.

This lecture, part of MIT's Principles of Microeconomics, develops the core economic model of consumer choice under explicit budget constraints, detailing the implications for utility maximization and demand.

This lecture derives individual and market demand curves, examining the critical concepts of price elasticity of demand and the decomposition of price changes into income and substitution effects.

This lecture introduces core concepts in producer theory, detailing the production function, short-run vs. long-run production, and the technical rate of substitution. It further examines returns to scale and measures of productivity within microeconomic frameworks.

This lecture, part of MIT's Principles of Microeconomics, extends producer theory by detailing the derivation and implications of short-run and long-run cost curves, including concepts such as total, average, and marginal costs.

This lecture concludes the analysis of production costs from prior sessions, then formally introduces the model of perfect competition. It details the conditions for short-run profit maximization for firms operating within such a market structure.

This lecture explicates the core tenets of perfect competition, examining short-run profit maximization, short-run equilibrium dynamics, and the long-run implications of competitive markets.

This session introduces the fundamental concepts of supply and demand curves, meticulously deriving and illustrating consumer surplus and producer surplus in market analysis.

This lecture systematically explores the principles of welfare economics, demonstrating how competitive markets maximize societal welfare and analyzing the effects of government interventions.

This lecture transitions from perfect competition to monopoly, focusing on the distinct mechanisms of monopoly profit maximization and the subsequent welfare effects on the economy.

This session delves into the origins of monopolies, examining various regulatory approaches and analyzing the concept of contestable markets as a potential constraint on monopoly power.

This lecture provides an introduction to oligopoly market structures, employing game theory principles and detailing the Cournot model for analyzing firm behavior and equilibrium outcomes.

This lecture extends the analysis of oligopolies, examining the formation and stability of cartels, comparing different equilibrium types, and exploring price competition among many firms.

This lecture initiates the study of factor markets, specifically focusing on the labor market by explicating the determinants of factor demand and factor supply for labor.

This session continues the examination of factor markets, illustrating key principles through the practical example of minimum wage policy and its effects on the labor market.

This lecture explores intertemporal decision-making, demonstrating how capital markets and the pricing of future resources influence economic choices in real-world scenarios.

This lecture addresses strategies for increasing savings as a driver of economic growth and provides an initial framework for understanding the fundamental concepts of international trade.

This session rigorously analyzes the welfare economics of international trade, focusing on comparative advantage and how these principles inform and shape trade policy decisions.

This lecture explicates the economic framework for decision-making under uncertainty, introducing core concepts that model agents' choices when outcomes are not guaranteed.

This lecture introduces the critical concepts of efficiency and equity in resource allocation, discussing the identification of socially optimal allocations, sources of inequality, and leakage.

This lecture extends the discourse on equity and efficiency, analyzing the mechanisms of government redistribution programs and the economic impacts of taxation within the United States.
