Consumer Choice Theory: Foundations of Economic Demand

Economics starts with understanding how individuals make choices under scarcity. This course provides a comprehensive introduction to the fundamental microeconomic theory of consumer choice. By the end of this course, you will be able to analyze consumer behavior using rigorous modeling tools, understand how changes in income and prices affect purchasing power, and confidently derive the basic principles of market demand. What you'll learn: * Understand the concept of constrained optimization and the role of scarcity in economic decisions. * Master the derivation and interpretation of budget constraints and their response to price and income shifts. * Learn how to represent consumer preferences using utility functions and indifference curves. * Apply the optimization rule (consumer equilibrium) to determine the optimal consumption bundle. * Analyze how income and substitution effects combine to explain the slope of the individual demand curve. * Practice calculating and interpreting key measures of responsiveness, such as price and income elasticity. The course begins by defining core terminology and establishing the constraints faced by consumers. It then moves into modeling preferences and utility before combining these elements to analyze consumer optimization and the resulting derivation of demand functions. This course is designed for absolute beginners in economics or microeconomics. No prior knowledge of economic theory or advanced mathematics is required; all concepts are explained clearly through written examples and practice exercises.
