In economics, a Veblen good is a member of a group of commodities for which people's preference for buying them increases as their price increases (as greater price confers greater status) instead of decreasing according to the law of demand. A Veblen good is often also a positional good.
Some types of luxury goods, such as high-end wines, designer handbags, and luxury cars, are Veblen goods, in that decreasing their prices decreases people's preference for buying them because they are no longer perceived as exclusive or high-status products. Similarly, a price increase may increase that high status and perception of exclusivity, thereby making the good even more preferable. Often such goods are no better or are even worse than their lower priced counterparts. However, this 'anomaly' is mitigated when one understands that the demand curve does not necessarily have only one peak. The goods generally thought to be Veblen goods are still subject to the curve since demand does not increase with price infinitely. Demand may go up with price within a certain price range, but at the top of that range the demand will cease to increase before it begins to fall again with further price increases.
At the other end of the spectrum, where 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: 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.
None of these effects in itself predict 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.
