A s individuals change jobs more frequently, it is increasingly important to understand what they carry from their prior work experience that affects their performance in a new organizational context. So far, explanations about the imperfect portability of experience have primarily been about firm specificity of knowledge and skill. We draw on psychological theory to propose additional sociocognitive factors that interfere with the transfer of knowledge and skill acquired from prior related work experience. As we hypothesized, we find that task-relevant knowledge and skill mediates the relationship between prior related experience and job performance and that it acts as suppressing mediator of a negative direct relationship between prior related experience and current job performance. We also find that the positive effect of prior related experience on task-relevant knowledge and skill is attenuated by higher levels of experience within the current firm.

An important area of investigation in the field of entrepreneurship examines how people and organizations exploit technological opportunities. Prior research suggests that alliances, the mobility of experts, and the informal mechanisms associated with geographic co-location can present firms with useful opportunities to source technological knowledge. This paper uses insights from strategic management and organizational theory to suggest that organizational size may have an important impact on the extent of external learning, since it differentially affects the likelihood of learning via formal and informal mechanisms. Examining a cross-section of semiconductor startups, we find that external learning increases with startup size. With regard to the specific mechanisms of learning, we find that firms learn from alliances regardless of their size. For the informal mechanisms of mobility and geographic co-location, however, learning decreases with firm size. These results suggest that as startups grow, they may have increasing opportunities to access and exploit external knowledge, but their motivation (and hence ability) to learn from more informal sources may decrease.

T he movement of personnel between firms has been shown to have important implications for firms, yet there has been little direct investigation of the underlying mechanisms. We propose that in addition to their human capital, mobile individuals carry social capital, affecting the outcomes of the firms they join and leave by altering the patterns of interaction between firms. In this study, we examine how job mobility affects firm influence in a technical standards setting committee for U.S. wireless telecommunications. We hypothesize and find that hiring individuals who are richer in social capital increases firm influence in technical standards setting committees by increasing the hiring firm's social capital. We also find the benefits of hiring social capital are attenuated when an interfirm relationship is maintained by multiple individuals. In contrast, we find that the loss of personnel does not affect a firm's social capital or influence over standards directly but that it does have an effect on firm social capital and influence contingent on changes in the firm's business strategy. In advancing these arguments, we address the broader question of individuals as carriers of social capital and the conditions under which interpersonal connections are appropriable by firms.

One of us or one of my friends: How social identity and tie strength shape the creative generativity of boundary-spanning ties AbstractSocial ties to colleagues on other work teams can spur creative ideas and workplace innovation by exposing an individual to diverse knowledge. However, for external knowledge to be recombined into innovation, the knowledge must first be recognized as potentially valuable. Going beyond traditional structural explanations, we predict that the use of diverse knowledge to generate creative ideas and solutions will depend in part on employees' psychological attachment to the organizational groups to which they belong, i.e. their social identity, and the strength of their social ties. We test our hypotheses in an R&D division of a global high-technology firm, finding that social identity influences the creative generativity of boundary-spanning ties. Specifically, stronger team identity renders interactions with colleagues on other work teams less generative of creative ideas, while identification with an overarching, superordinate group (e.g., a division) enhances creative generativity. We also hypothesize and find that tie strength attenuates the negative effect of team identity.
