Best Is Average, Better Is Best: Difference between revisions

According to US government regulations, certain products are considered commodity items (in technical jargon, ''parity products''), with no noticeable variation in quality from manufacturer to manufacturer. As far as the government is concerned, there is no functional difference between one product and another in a given parity class. Aspirin, toothpaste, toilet paper and a host of other consumer goods fall into this category. Economics would call this item one that causes Perfect Competition, so manufacturers, to sell their brand, must differentiate it from the others.
