“…According to RBV, both of product extensions and brand extensions are important strategic devices that allow a firm to grow, not only by leveraging its current customer base and current (parent) brand image (Balachander & Ghose, 2003;Park, Jaworski, & MacInnis, 1986), but also through utilizing other operating resources, such as technology, logistics, and manufacturing capabilities (Essig, Glas, Selviaridis, & Roehrich, 2016;Kaipia, & Turkulainen, 2017;Lacoste, 2016;Srivastava, Shervani, & Fahey, 1998). However, in contrast to product extensions, brand extensions require technological and product-market expertise and configurations of business relationships that are different across sectors and face a different set of competitors from those of the existing product (Fleming, Lynch, & Kelliher, 2016;Kohtamäki, & Rajala, 2016;Mudambi, et al, 2017;Nerkar & Roberts, 2004;Peters, Pressey, & Johnston, 2017). This will introduce differential effect of product extensions and brand extensions on firms' performance.…”
