In economics, Veblen goods are types of material commodities for which the demand is proportional to its high price, which is an apparent contradiction of the law of demand; Veblen goods also are commodities that function as positional goods. Veblen goods are types of luxury goods, such as expensive wines, jewelry, fashion-designer handbags, and luxury cars, which are in demand, because of the high prices asked for them, thus, increasing their desirability as symbols of the buyer's high social-status, by way of conspicuous consumption and conspicuous leisure; conversely, a decrease of the prices of Veblen goods would decrease demand for the products.
In an economy, the consumption of Veblen goods is a function of the Veblen effect (goods desired for being over-priced) that is named after the American economist Thorstein Veblen, who first identified conspicuous consumption as a mode of status-seeking in The Theory of the Leisure Class (1899) in the late 19th century.
A price increase may increase that high status and perception of exclusivity, thereby making the good even more preferable. At the other end of the spectrum, with luxury items priced equal to non-luxury items of lower quality, all else being equal more people would buy the luxury items, even though a few Veblen-seekers would not. Thus, even a Veblen good is subject to the dictum that demand moves conversely to price, although the response of demand to price is not consistent at all points on the demand curve.
- The snob effect: expressed preference for goods because they are different from those commonly preferred; in other words, for consumers who want to use exclusive products, price is quality.
- The bandwagon effect: preference for a good increases as the number of people buying them increases (a psychological effect).
- The network effect: value of a good increases as the number of buyers or users increases (e.g., as the number of people with telephones or Facebook increased, the value of having a telephone or being on Facebook increased since the user could reach more people).
- The common law of business balance: low price of a good indicates that the producer may have compromised quality, that is, "you get what you pay for".
None of these effects in itself predicts what will happen to actual quantity of goods demanded (the number of units purchased) as prices change—they refer only to preferences or propensities to purchase. The actual effect on quantity demanded will depend on the range of other goods available, their prices, and their substitutabilities for the goods concerned. The effects are anomalies within demand theory because the theory normally assumes that preferences are independent of price or the number of units being sold. They are therefore collectively referred to as interaction effects.
The interaction effects are a different kind of anomaly from that posed by Giffen goods. The Giffen goods theory is one for which observed demand rises as price rises, but the effect arises without any interaction between price and preference—it results from the interplay of the income effect and the substitution effect of a change in price.
Recent research has begun to examine the empirical evidence for the existence of goods which show these interaction effects. The Yale Law Journal has published a broad overview. Studies have also found evidence suggesting people receive more pleasure from more expensive goods.
