Fabio Caldieraro, Ling-Jing Kao, & Marcus Cunha Jr. Harmful Upward Line Extensions: Can the Launch of Premium Products Result in Competitive Disadvantages? Companies often extend product lines with the goal of increasing demand for their products and responding to competitive threats. Although line extensions may lead to cannibalization and reduction of overall profit, the bulk of theoretical and empirical research has suggested that product line extensions result in a net gain of overall demand and market share. To mitigate cannibalization, the extant literature prescribes the addition of premium versions of products, or “upward line extensions,” with the intention of achieving gains not only in demand and market share but also in overall profit. In this research, the authors employ analytical and empirical methods to make the case that upward line extensions aimed at matching a competing product’s attribute may lead consumers to reassess their perceptions about the brand and the attributes of products in the market in a way that erodes the advantages of the extending firm. Ultimately, this can result in a loss of demand, market share, and profit for the extending firm.

The appeal of by showing that upward product line extension decisions may launching a premium product with attributes similar to those lead to a loss of overall sales and market share and may of a competitor’s product (and dissimilar to the main brand’s negatively affect profit.
