Meaning of Duality The term duality is habitually used to denote a dissimilarity between two correlated concepts, such as duel characteristics of developing economies. It means duality is related to looking for a particular thing in different two alternative ways. Thus, in consumer theory, duality is the alternative way of looking at the consumer’s utility […]

In our situation of good X, good Y, and money income M; if money income and the price of good Y stays the same but the price of good X rises, then the consumer will feel poorer, and if the price of good X falls, then the consumer will feel richer. This observation has led

Learning Objective To explain the derivation of income consumption and Engel curve for a normal and inferior good This issue deals with the impact of change in income on the quantity demanded of good measured along the x-axis (generally quantity demanded of good X). If we hold all the prices of goods constant and increase
Income Consumption and Engel Curve Read More »
Introduction In the analysis of consumer’s equilibrium, price and income are exogenous variables, and changes in the values of these variables have a direct effect on the consumer’s equilibrium or the consumer’s optimal choice of the goods. The effect of change in money income on the consumer’s optimal purchase decision is traced by the income
Change in Prices and Derivation of Demand Curve Read More »
Introduction The theory of consumer behavior and demand is grounded on the assumption that consumers try to allot limited money income among available goods and services to maximize satisfaction. The consumer purchases to maximize satisfaction subject to the constraint that these purchases do not exceed the consumer’s limited money income. Thus, for the theory of

Introduction A consumer attains his/her equilibrium when he/she maximizes his/her total utility, given his/her income and the prices of the two commodities. We combine the indifference curves and the budget line on the same diagram to illustrate the consumer’s equilibrium graphically. The indifference curve in the utility analysis assumes that the consumer tries to maximize
Consumer’s Equilibrium with Indifference Curve Approach Read More »
Learning Objective To explain the technique and solution of the consumption decision problem Once the consumer identifies his or her preference concerning several consumption bundles represented by the indifference map and which bundles can or cannot be afforded represented by the budget line, the decision problem is now related to the consumption decision. The straightforward

Background and Concept of Preference Ordering Learning Objective To explain the concept of preference ordering and axioms of preference ordering Every individual consumer or each household has a fairly accurate notion of money income for a reasonable period. It also has some notion (perhaps not well defined) of the goods and services it wants to

Learning Objective To explain the similarities and differences between cardinal and ordinal utility analysis (cardinal utility versus ordinal utility) Ordinal utility analysis is considered the improved form of cardinal utility analysis and is also considered a superior method to study consumer’s behavior. Indifference curve analysis is more objective, more scientific, and more applicable because
Cardinal Utility Versus Ordinal Utility Read More »
Besides the analysis of consumer behavior and consumer demand, the technique of the indifference curve can be used in the analysis of several other economic phenomena and issues. Mainly the technique of indifference curves is applied in the areas like consumer’s surplus, the individual labor supply curve, numerous doctrines of welfare economics, the burden of
