"Peer networks are seen as important for stimulating innovation and entrepreneurship, but little is known about how the structure and composition of networks affect innovation performance. Researchers compared the effects of face-to-face and virtual peer interaction on the submission and quality of business proposals by individuals from 49 African countries enrolled in an online entrepreneurship course. They found that face-to-face networks and the virtual interaction of groups of entrepreneurs of the same nationality increased the submission of business proposals to a funding competition, but that virtual interaction had no effect when groups were formed with entrepreneurs of different nationalities. Virtual interaction among entrepreneurs of the same nationality was also found to increase the quality of submitted business proposals."
