Responding to Digital Transformation by External Corporate Venturing: An Enterprising Family Identity and Communication Patterns Perspective

Digital transformation increasingly requires activities located outside firm boundaries, for example via alliances with start‐up companies. Despite this, German Mittelstand firms, primarily owned and managed by enterprising families and seen as role models of innovation, appear reluctant to place strategic emphasis on venturing outside the firm’s boundaries when it comes to digital transformation. Drawing on the concepts of identity and communication patterns, we theorize on the mechanisms behind this behaviour. Applying structural equation modelling to a sample of 254 members of the next generation in enterprising families from Germany, we find that family communication patterns impact the strategic priority for or against external corporate venturing via identity‐related considerations.

The impact of cognitive age on Internet use of the elderly: an introduction to the public policy implications

Despite the growth of the Internet, one area that has not really been discussed is the elderly's use of the Internet. Given the rapid growth of this population as well as the potential the Internet holds for them, it is a subject worth consideration. However, seniors cannot be defined simply by their chronological age, but by their cognitive age. This paper discusses the impact of cognitive age of a national random sample of American elderly consumers on their Internet use. The results suggest that those seniors with a younger cognitive age use the Internet more than those seniors with an older cognitive age. Additionally, seniors with a younger cognitive age have more social contact off‐line (but not online) than those seniors with an older cognitive age. Finally, in terms of demographic variables, chronological age is positively associated with cognitive age and women report a younger cognitive age than men. These results suggest that for policy makers interested in increasing the participation of seniors, they can utilize the Internet to reach those who are younger in terms of cognitive age; however, they will not be able to reach all seniors in this manner and they need to utilize the Internet as a complementing media to their traditional communication sources.
