People shift their spending across food, housing, transportation, health care, and other goods and services categories as family income rises. The law known as:

Question

Accepted Answer

The correct option is 1:

Engel's Law is the correct choice because it directly addresses the relationship between a family's rising income and the resulting composition of their expenditure. Formulated by the German statistician Ernst Engel, this observation is a cornerstone of consumption economics. The law states that as household income increases, the proportion of income spent on food declines, even though the absolute amount spent on food may increase. This decline in the relative expenditure on the necessity of food frees up a larger share of the budget, allowing for a proportionally greater increase in spending on what are considered luxury goods, discretionary items, and non-food necessities like housing, transportation, healthcare, and education. This shifting of spending priorities from basic necessities to higher-level goods and services is the exact phenomenon described in the question.

The incorrect option is 2:
Peter's Law, often referred to as The Peter Principle, is a concept from organizational management, not consumer economics. It famously states that in a hierarchy, employees tend to be promoted until they reach a level at which they are no longer competent. This law focuses on career progression and managerial incompetence within a corporate structure. Therefore, it has no application to the changes in a household budget or the consumption patterns of families based on their income levels.

The incorrect option is 3:
John's Law is not a recognized or standard principle in the fields of economics, management, or sociology related to consumer expenditure. In the context of academic or competitive examinations, terms like this are often used as non-existent distracters to test the candidate's knowledge of the established theories. Therefore, it provides no explanation for the observed shift in spending as family income rises.

The incorrect option is 4:
Right's Law, or the experience curve/learning curve, is a principle related to manufacturing and production efficiency. It suggests that production costs decline systematically with every cumulative doubling of production volume, indicating a learning process within the factory. This economic law focuses on the cost-effectiveness of mass production over time and the reduction in unit cost. It does not analyze or predict consumer and family spending habits as income changes.
