PERSONAL INCOME AND NATIONAL INCOME: Personal income (PI) is the total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time. National income (NI) is the total income earned by the citizens of the national economy resulting from their ownership of resources used in the production, which may or may not be received by members of the household sector. Personal income can be derived from national income by subtracting income earned but not received (IEBNR) and adding income received but not earned (IRBNE).

A principle stating that monopolistically competitive firms seek to maintain similarities between products at the same time they promote differences.

This principle is also termed Hotelling's paradox.
