Introduction to Consumer Theory in Microeconomics

Do you want to understand the fundamental laws governing demand and purchasing behavior in an economy? Consumer Theory provides the essential framework for modeling how individuals make choices about goods and services. This course provides a detailed, step-by-step introduction to classic Consumer Theory. By the end, you will be able to define concepts like utility and marginal rate of substitution, calculate consumer equilibrium, and analyze how changes in income and price affect market demand. What you'll learn: * Understand the concept of utility, differentiating between cardinal and ordinal approaches to measuring satisfaction. * Practice constructing and interpreting budget lines and analyzing the impact of price changes and income shifts on purchasing power. * Learn how to use indifference curves to map consumer preferences and derive the optimal point of consumer equilibrium. * Analyze the income effect and substitution effect, explaining how they combine to determine the final change in demand for normal and inferior goods. * Apply the core assumptions of rational choice theory and understand the limitations of the traditional consumer model. * Derive individual demand curves and understand their relationship to price consumption curves. The course begins with foundational definitions of scarcity and choice, progresses through utility analysis and the geometry of budget constraints, and concludes with the determination of consumer equilibrium and demand elasticity. You will work through practical examples and written exercises throughout each section. This introductory course is designed for absolute beginners in economics, including students and anyone seeking a solid foundation in microeconomic principles. No prior knowledge of economics or advanced mathematics is required. Start building your foundational understanding of economic behavior today.
