Research Summary: This study investigates incumbent responses to a main rival’s exit. We argue that long‐time rivals have developed an equilibrium by offering a mix of overlapping and unique products and by choosing geographic proximity to each other. A rival’s exit, however, disrupts this equilibrium and motivates surviving firms to expand in both product and geographic spaces to seek a new equilibrium. Using data from all U.S. Best Buy stores before and after the exit of Circuit City, we find that Best Buy uses product variety expansion as its major response in markets where Circuit City was colocated, but it more often responds by opening new stores in non‐colocated markets. Regardless of preexisting market structures, the magnitude of product variety expansion decreases with the opening of new stores.
Managerial Summary: How do surviving firms respond to a major rival’s exit? By studying Best Buy’s responses to Circuit City’s withdrawal, we find the survivor expands in both product space (increasing product variety) and geographic space (opening new stores), due to two motives. First, the survivor strives to fill in “holes” left in the market. Second, the survivor experiences uncertainty in the post‐exit world wherein its reference point is gone, threat of potential entry looms, and it lacks information about new entrants. Thus, it must deter potential entry ex ante by preempting many prime product and geographic locations. Best Buy also responds according to preexisting market structures, primarily through product variety expansion in markets wherein Circuit City was colocated and through opening new stores in non‐colocated markets.

Strategic management research traditionally uses experiential learning arguments to explain the existence of a positive relationship between repetition of an activity and superior performance. We propose an alternative interpretation of this relationship in the context of discrete corporate development activities, which are generally self-selected on the basis of superior performance expectations. We argue that firms are likely to choose to repeat successful activities, thereby accumulating high experience with them. To demonstrate this ‘self-selection’ effect, we examine the performance of 437 aircraft projects launched through three introduction modes. We show that the positive performance effect of the firm’s experience with the focal mode vanishes after accounting for experience endogeneity. We suggest that in a general case, experience with corporate development activities may be tinged with both learning as well as selection effects. Therefore, omitting experience endogeneity may lead researchers to draw incorrect conclusions from an “empirically observed” positive experience-performance relationship.

M&A and organic growth are two common strategies for firms to achieve horizontal growth. In this study, we disentangle two distinct sources of firm performance corresponding to different theoretical perspectives on firm size: firms’ bargaining power with respect to suppliers and customers, and operating efficiency arising from scale economies. We conceptually argue and empirically show that relatively, M&A enhance bargaining power while organic growth enhances operating efficiency. We also find that M&A’s disadvantage on operating efficiency persists over time. In order to disaggregate these effects, we use accounting rather than financial or managerial data and test our predictions in the global retail industry over a 20 year period. We examine implications of these results for sustainability of size-based competitive advantages.

Product variety is an important strategic tool that firms can use to attract customers and respond to competition. This study focuses on the retail industry and investigates how stores manage their product variety, contingent on the presence of competition and their actual distance from rivals. Using a unique data set that contains all Best Buy and Circuit City stores in the United States, the authors find that a store’s product variety (i.e., number of stock-keeping units) increases if a rival store exists in its market but, in the presence of such competition, decreases when the rival store is collocated (within one mile of the focal store). Moreover, collocated rival stores tend to differentiate themselves by overlapping less in product range than do non-collocated rivals. This smaller and more differentiated product variety may be because of coordinated interactions between collocated stores. In summary, this paper presents evidence of both coordination and competition in retailers’ use of product variety.
