Social structure,reasonable gain,and entrepreneurship in Africa

In the context of desperate poverty, characterized by households at subsistence level that experience economic loss and social fracture, explanations for why individuals undertake entry into entrepreneurship are limited. We find that individuals rely on their social relationships to enable entrepreneurial activities that have the potential to create a reasonable income gain. In a sample of 1,049 households in rural Kenya, we test whether the disintegration of social structure attenuates entrepreneurial behavior. When coupled with factors such as income loss, gender of the household head, and access to communal resources, social structure plays a pivotal role in entrepreneurial action. We propose that the search for reasonable income gain is a key driver of entrepreneurial action at subsistence levels, thereby adding to behavioral explanations of entrepreneurship.

Appropriability and the retrieval of knowledge after spillovers

Research summary: Firms create and capture value through innovation. In technology‐driven firms, there has been an explicit emphasis on appropriability through imitation deterrence and cumulative inventions that build on prior firm innovation. We introduce systematic empirical evidence for a third mechanism of appropriability namely, knowledge retrieval, which is defined as the re‐absorption of previously spilled knowledge. We extend previous studies which consider technological complexity and organizational coupling as predictors of appropriability by examining their impact on knowledge retrieval. We find that technological complexity has a curvilinear relationship with retrieval while organizational coupling has a negative relationship. We discuss the implications of these findings for theories of absorptive capacity, organizational design and appropriability of innovation. Managerial summary: It is a widely held assumption that knowledge should be protected and held tightly within the firm to ensure value creation and value capture. The implicit recognition is that knowledge spillovers, or knowledge leakage, is detrimental to performance. By examining the patterns of citations among patents of 142 semiconductor firms, we study how organizational structure and technological complexity play a role. We find that moderate technological complexity improves appropriability. If imitation deterrence is paramount, then the optimal structure would be a tightly‐coupled organization. In other instances, loosely‐coupled organizations may be superior because they foster internal cumulative innovations and, if spillovers were to occur, they also maximize knowledge retrieval. Our findings suggest that all is not lost when spillovers occur and that firms can continue to benefit in downstream innovations. Copyright © 2015 John Wiley & Sons, Ltd.
