Consumer preferences are based on a few assumptions that help simplify consumer behavior.
A market basket or a bundle refers to a combination of goods and services a consumer can purchase, such as food, clothing, and entertainment.
The completeness assumption states that a consumer can compare and rank two or more baskets. This allows for consistent decision-making in economic models.
For example, Nicole is considering two baskets. Basket A has an expensive smartphone with standard earbuds. Basket B contains a mid-range smartphone with premium earbuds.
With the completeness assumption, Nicole can rank these options: she may prefer Basket A over Basket B, favor Basket B over A, or be indifferent between the two.
The assumption of monotonic preference implies that a consumer considers an increase in consumption better. It means a consumer prefers to have more of something rather than less.
For example, Nicole highly values vacation days. She is considering two jobs, if Job A offers 20 vacation days and a $50,000 salary, while Job B offers 30 vacation days and a $55,000 salary, monotonic preferences would imply Nicole chooses Job B, as it offers more of both goods.
