📊 Budget Line, Budget Set & Consumer’s Budget | Shifts, Numericals & Lagrange Function In this lecture, we develop a comprehensive understanding of the Budget Line and its role in the Theory of Consumer Behaviour. The budget constraint represents the different combinations of goods that a consumer can afford, given the consumer’s income and the market prices of goods. The lecture explains the Consumer’s Budget, Budget Set, and Budget Line in detail, along with the slope and intercepts of the budget line. We also examine how changes in consumer income and commodity prices lead to parallel shifts and rotations of the budget line. Special emphasis is placed on numerical problems related to the budget equation, calculation of intercepts, slope, and changes in the budget line resulting from variations in income and prices. The lecture further introduces the Lagrange Function as a method of constrained optimization, explaining how consumers maximize utility subject to their budget constraint. This provides the foundation for understanding consumer equilibrium and utility-maximizing behaviour in Microeconomic Theory. This lecture is highly useful for students studying Consumer Behaviour and Microeconomic Theory and for those preparing for UGC NET Economics, JKSET Economics, CUET PG Economics, MA Economics, BA Economics, university examinations, and other competitive examinations.
