Recognition of the firm's tendency toward local search has given rise to concepts celebrating exploration that overcomes this tendency. To move beyond local search requires that exploration span some boundary, be it organizational or technological. While several studies have encouraged boundary-spanning exploration, few have considered both types of boundaries systematically. In doing so, we create a typology of exploration behaviors: local exploration spans neither boundary, external boundary-spanning exploration spans the firm boundary only, internal boundary-spanning exploration spans the technological boundary only, and radical exploration spans both boundaries. Using this typology, we analyze the impact of knowledge generated by these different types of exploration on subsequent technological evolution.In our study of patenting activity in optical disk technology, we find that exploration that does not span organizational boundaries consistently generates lower impact on subsequent technological evolution. In addition, we find that the impact of exploration on subsequent technological evolution within the optical disk domain is highest when the exploration spans organizational boundaries but not technological boundaries. At the same time, we find that the impact of exploration on subsequent technological development beyond the optical disk domain is greatest when exploration spans both organizational and technological boundaries.

Recent research suggests that, due to organizational and relational constraints, firms are limited contextually---both geographically and technologically---in their search for new knowledge. But distant contexts may offer ideas and insights that can be extremely useful to innovation through knowledge recombination. So how can firms reach beyond their existing contexts in their search for new knowledge? In this paper, we suggest that two mechanisms---alliances and the mobility of inventors---can serve as bridges to distant contexts and, thus, enable firms to overcome the constraints of contextually localized search. Through the analysis of patent citation patterns in the semiconductor industry, we first demonstrate both the geographic and technological localization of knowledge. We then explore if the formation of alliances and mobility of active inventors facilitate interfirm knowledge flows across contexts. We find that mobility is associated with interfirm knowledge flows regardless of geographic proximity and, in fact, the usefulness of alliances and mobility increases with technological distance. These findings suggest that firms can employ knowledge acquisition mechanisms to fill in the holes of their existing technological and geographic context.Knowledge, Alliances, Mobility, Patents, Localization

Do firms balance exploration and exploitation in their alliance formation decisions and, if so, why and how? We argue that absorptive capacity and organizational inertia impose conflicting pressures for exploration and exploitation with respect to the value chain function of alliances, the attributes of partners, and partners' network positions. Although path dependencies reinforce either exploration or exploitation within each of these domains, we find that firms balance their tendencies to explore and exploit over time and across domains.

Organizational research advocates that firms balance exploration and exploitation, yet it acknowledges inherent challenges in reconciling these opposing activities. To overcome these challenges, such research suggests that firms establish organizational separation between exploring and exploiting units or engage in temporal separation whereby they oscillate between exploration and exploitation over time. Nevertheless, these approaches entail resource allocation trade-offs and conflicting organizational routines, which may undermine organizational performance as firms seek to balance exploration and exploitation within a discrete field of organizational activity (i.e., domain). We posit that firms can overcome such impediments and enhance their performance if they explore in one domain while exploiting in another. Studying the alliance portfolios of software firms, we demonstrate that firms do not typically benefit from balancing exploration and exploitation within the function domain (technology versus marketing and production alliances) and structure domain (new versus prior partners). Nevertheless, firms that balance exploration and exploitation across these domains by engaging in research and development alliances while collaborating with their prior partners, or alternatively, by forming marketing and production alliances while seeking new partners, gain in profits and market value. Moreover, we reveal that increases in firm size that exacerbate resource allocation trade-offs and routine rigidity reinforce the benefits of balance across domains and the costs of balance within domains. Our domain separation approach offers new insights into how firms can benefit from balancing exploration and exploitation. What matters is not simply whether firms balance exploration and exploitation in their alliance formation decisions but the means by which they achieve such balance.

Theories of innovation diffusion no longer focus exclusively on explaining the rate at which innovations diffuse or the sequence in which they are adopted. They also focus on explaining why certain innovations diffuse extensively, becoming de facto standards, whereas others do so partially or not at all. Many of these theories specify a bandwagon process: a positive feedback loop in which increases in the number of adopters create stronger bandwagon pressures, and stronger bandwagon pressures, in turn, cause increases in the number of adopters. Factors affecting if and how many times this feedback loop cycles explain if and how many potential adopters jump on a bandwagon. We argue that one important factor has not yet been incorporated into theories explaining bandwagons' extent: the structure of social networks through which potential adopters of innovations find out information about these innovations which can cause them to adopt these innovations. We advance a theory of how the structure of social networks affects bandwagons' extent. We propose that both the number of network links, as well as small, seemingly insignificant idiosyncracies of their structures, can have very large effects on the extent of an innovation's diffusion among members of a social network.
