It is often conceded that heavily advertised products cost more than those that are not advertised extensively. But there is considerable disagreement concerning what this difference means. Advertising's critics often claim it is evidence of monopolistic control over supply and prices, while advertising's defenders generally contend it reflects the higher quality of advertised brands. Surprisingly, there has been almost no research into whether or not heavily advertised goods are of better quality. As a preliminary inquiry into this interesting question, this paper attempts to examine the relationship between advertising expenditures and product quality.
