QCM : Consumer Choice and Utility Theory — 10 questions

Explication

Consumer utility maximization is the process where consumers choose the combination of goods and services that provides the highest utility possible within their budget constraint, guided by the condition that marginal utility equals the price (MU = p). This ensures they allocate their resources optimally to achieve maximum satisfaction.

Explication

von Neumann & Morgenstern (1944) are credited with formalizing the utility function within expected utility theory, providing the mathematical foundation for representing preferences under risk.

Explication

Utility measurement and indifference serve to represent consumer preferences in a mathematical form, enabling analysis of choices and decision-making, especially under risk and uncertainty.

Explication

Expected utility theory was first established by Bernoulli in 1738, marking the beginning of formal analysis of decision-making under risk, which underpins the concepts of utility maximization and budget constraints.

Explication

The Law of Demand states that there is an inverse relationship between price and quantity demanded, meaning demand generally decreases as price increases. Elasticity, on the other hand, measures how much demand responds to a change in price, i.e., the sensitivity or responsiveness of demand to price changes.

Explication

Alfred Marshall is credited with formalizing the concept of price elasticity of demand in his work on demand and supply, making him the key figure associated with its development.

Explication

An increase in consumer income causes demand for normal goods to rise because consumers have more purchasing power, leading them to buy more of these goods. Conversely, demand for inferior goods decreases because consumers shift away from cheaper alternatives when they can afford better options. This is a fundamental cause-effect relationship in the theory of types of goods and income effects.

Explication

When the price of a substitute increases, consumers tend to buy more of the other substitute, so demand for the good increases. This reflects the substitutive relationship where higher prices of substitutes make the other more attractive.

Explication

Rational decision-making assumes that consumers have complete and transitive preferences, which allow their choices to be represented by a utility function, ensuring consistency and comparability in their decisions.

Explication

Expected Utility Theory is primarily understood as a model where consumers evaluate risky prospects by calculating the probability-weighted average of their utility outcomes, not just monetary values. This approach captures decision-making under risk by focusing on utility, as introduced by Bernoulli in 1738.
