Consumer Equilibrium: The Ordinal Approach

Understanding why consumers choose certain goods over others is fundamental to microeconomics, but the underlying theories can seem complex. This course provides a complete foundational explanation of the Ordinal Approach to consumer theory, enabling you to analyze consumer behavior, preferences, and optimal consumption bundles using the powerful tool of indifference curves. Upon completion, you will be able to interpret and apply the core principles that govern rational consumer decision-making. What you'll learn: * Understand the core concepts of utility, preferences, and the fundamental assumptions of the ordinal approach. * Master the construction, properties, and interpretation of indifference curves and indifference maps. * Analyze the concepts of the budget line, budget set, and the Marginal Rate of Substitution (MRS). * Apply the necessary conditions to determine consumer equilibrium using the tangency rule. * Practice analyzing the effects of changes in income and price on consumer choices. * Differentiate between the income effect and the substitution effect derived from price changes. The course begins with foundational definitions of preferences and utility, progressing systematically through the geometry of indifference curves and budget constraints. Finally, you will apply these tools to solve for the optimal consumption bundle and analyze how consumers react to market changes. This course is designed for absolute beginners in economics, as well as students seeking a clear, detailed explanation of consumer theory fundamentals.
