Key Concepts

Indifference Curves

Indifference curves represent combinations of different goods between which a consumer is indifferent, as each combination provides the same level of utility or satisfaction. They are used to illustrate consumer preferences and trade-offs, and their typical convex shape reflects the principle of diminishing marginal rates of substitution between goods.

Budget Constraints

Budget constraints depict the set of all combinations of goods that a consumer can afford given their income and the prices of the goods. The slope of the budget line is determined by the ratio of the prices of the two goods, and shifts in income or prices affect the position of the constraint, which in turn influences consumption decisions.

Normal Goods

Normal goods are those for which demand increases as consumer income rises. In the framework of indifference curves and budget constraints, an increase in income shifts the budget line outward, allowing the consumer to reach a higher indifference curve by increasing consumption of normal goods.

Inferior Goods

Inferior goods are characterized by a decrease in demand when consumer income increases. However, it is conceptually inconsistent for all goods to be classified as inferior because if every good were inferior, an increase in income would not lead to an increase in overall utility. This contradicts the observed behavior that consumers can always reach higher satisfaction levels with higher incomes, thereby implying that at least some goods must be normal.
