The snob effect is a phenomenon described in microeconomics as a situation where the demand for a certain good by individuals of a higher income level is inversely related to its demand by those of a lower income level. The 'snob effect' contrasts most other microeconomic models, in that the demand curve can have a positive slope, rather than the typical negatively sloped demand curve of normal goods.

The 'snob effect' contrasts most other microeconomic models, in that the demand curve can have a positive slope, rather than the typical negatively sloped demand curve of normal goods. This situation is derived by the desire to own unusual, expensive or unique goods. For consumers who want to use exclusive products, price is quality. These goods usually have a high economic value, but low practical value. The less of an item available, the higher its snob value. Examples of such items with general snob value are rare works of art, designer clothing, and sports cars.
