Complementarity,capabilities, and the boundaries of the firm: the impact of within‐firm and interfirm expertise on concurrent sourcing of complementary components

Theories of the firm raise conflicting arguments about how complementarities between two or more components affect firms' knowledge and production boundaries. Traditional arguments in the boundaries of the firm literature suggest that firms will tend to produce sets of complementary components internally, while more recent modularity studies argue that firms can outsource to gain flexibility. We resolve these views by examining concurrent sourcing, which arises when firms both make and buy the same components. We argue that concurrent sourcing of complementary components becomes more common in two cases: when firms have relevant knowledge about the components in conjunction with suppliers (interfirm expertise) and, perhaps more surprisingly, within the firm (within‐firm shared expertise). The results suggest that firms often need to make in order to know, but can partially outsource if they possess sufficient expertise. Copyright © 2009 John Wiley & Sons, Ltd.     

Cutting the Gordian knot: The effect of knowledge complexity on employee mobility and entrepreneurship

Employee entrepreneurship and employee moves to rival firms (employee mobility) have both been recognized as critical drivers of the transfer of knowledge. Drawing on a unique database of intra‐industry inventor entrepreneurship and mobility events in the U.S. semiconductor industry, I examine the effect of the complexity of inventors' prior patenting activities on their decisions to join a rival firm or found a start‐up. The findings show that even though complexity inhibits knowledge diffusion to rival firms through employee mobility, complex knowledge may be underexploited within existing organizations and may still flow to startups through employee entrepreneurship. This study sheds new light on how technology shapes patterns of employee entrepreneurship and mobility, with implications for knowledge flows and competitive dynamics.     

Heterogeneity in turnover: The effect of relative compensation dispersion of firms on the mobility and entrepreneurship of extreme performers

We explore the strategic implications of firm compensation dispersion on the heterogeneous turnover outcomes of employee mobility and entrepreneurship. We theorize that individuals' turnover decisions are affected by the interaction of individual performance with the firm's compensation dispersion relative to its competitors. We test our theory using linked employer-employee data from the legal services industry. We find that individuals with extreme high performance are less likely to leave firms that offer higher compensation dispersion than competitors, however, if they do leave these employers, they are more likely to create new ventures. In contrast, employees with extreme low performance are more likely to leave firms with more compensation dispersion than competitors, and these individuals are less likely to engage in new venture creation.
