包包要買限量版，跑車偏愛特別設(shè)計，衣服必須專門定制……想擁有只有少數(shù)人才能享用的或獨一無二的商品，這種偏好就是“虛榮效應(yīng)”。

Snob effect refers to the desire to purchase something only because it is extremely expensive or extremely rare.
購買一樣商品只因為它特別昂貴或者極度稀缺，這種購物欲望就是“虛榮效應(yīng)”。

Snob effects is the phenomenon that a thing becomes more desirable because fewer people can afford it or can find one.
在“虛榮效應(yīng)”現(xiàn)象中，由于非常少的人才能買得起或者買得到，會導(dǎo)致人們購買這件物品的欲望更為強烈。

This situation is derived by the desire to own unusual, expensive or unique goods. 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.
這來自于人們想擁有非同尋常的、昂貴的或者獨特的商品的愿望。這些商品通常很昂貴，但卻沒那么實用。一件商品越稀缺，其“虛榮價值”就越高。藝術(shù)珍品、專門設(shè)計的服裝、和跑車屬于此列。
