Microeconomics: Cardinal Utility Analysis

Study Notes

Economics is the social science that studies how societies allocate scarce resources to satisfy unlimited wants and needs. It is broadly divided into macroeconomics and microeconomics.

Microeconomics

Microeconomics focuses on the behavior of individual economic agents, like consumers, firms, and industries. It examines how these agents make decisions in markets, considering factors like supply and demand, costs, and prices.
Key concepts in microeconomics include supply and demand, elasticity, market structures (perfect competition, monopoly, oligopoly), production, cost, and profit maximization.

Cardinal Utility Analysis of Demand

Cardinal utility analysis assumes that utility (satisfaction) derived from consuming a good can be measured and assigned numerical values, referred to as cardinal utility.
This approach argues that consumers can precisely quantify the satisfaction they get from different quantities of a good consumed. This contrasts with ordinal utility analysis, where only the relative preference among options is considered.
A fundamental assumption of cardinal utility analysis is that units of utility are comparable across different goods.
The concept of total utility and marginal utility is central to cardinal utility analysis.
- Total Utility: The overall satisfaction derived from consuming a certain quantity of a good.
- Marginal Utility: The extra satisfaction gained from consuming one additional unit of a good. Marginal utility typically diminishes as consumption increases
The law of diminishing marginal utility states that as a consumer consumes more of a good, the marginal utility derived from each additional unit decreases.
Consumer equilibrium under cardinal utility analysis occurs when the marginal utility per dollar spent is equal across all goods consumed. Consumers maximize their total utility when this condition holds.
Demand curves are derived by analyzing consumer equilibrium at various prices and then plotting the quantity demanded at each price. The demand curve illustrates the relationship between price and quantity demanded.
Marginal utility theory explains the downward slope of the demand curve. As the price of a good decreases, the marginal utility per dollar spent increases, encouraging consumers to buy more of the good.
Limitations of Cardinal Utility Analysis. This approach is considered less realistic compared to ordinal utility. It faces challenges in precisely measuring utilities and ensuring that utility units across goods are comparable. These limitations contributed to the later development of ordinal utility analysis.

Description

This quiz explores the key concepts of microeconomics, focusing specifically on cardinal utility analysis of demand. It examines how individual economic agents make decisions based on the quantifiable satisfaction derived from goods. Test your understanding of supply, demand, and the measurement of utility.
