Virtual and Face-to-Face Peer Interactions to Improve the Quality of Business Proposals among Entrepreneurs in 49 Countries across Africa

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.
Innovation is thought to play an important role in enterprise growth and it is widely considered a key driver of economic development. One of the many ways to encourage innovation is through peer networks, as they have the potential to stimulate innovation through cooperation, learning, and competition. Peers can be a source of motivation, new information, and diverse perspectives. While interaction among peers who are similar may foster support through familiarity, competition for funding may affect the extent of collaboration. Similarly, while some diversity in peer networks may stimulate innovation, too much diversity could suppress it. Thus, the structure of the channels through which peers interact and communicate matters.
Context of the evaluation
Entrepreneurs from all over Africa were recruited to take part in an online entrepreneurship course through a variety of channels, including: a large social media campaign, encouraging registered participants to recruit others, and information events on the ground. In total, 4,958 participants from 49 different African countries registered for the course, although not all regions were proportionally represented. In particular, 53 percent of participants were from West Africa while only 1 percent were from Northern Africa. 80 percent of participants had completed university and the average age was about 30 years old. 31 percent of participants were female and 63 percent already had a business when they were recruited. Additionally, while most of the participants had savings in a bank account (90 percent), only 9 percent had ever received a loan from the bank. Participants also had an average of more than 5 years of work experience, and 55 percent were employed.
Details of the intervention
Researchers conducted a randomized evaluation to understand the impact of an online entrepreneurship course and different forms of peer interaction on the quality of ideas, innovation efforts and entrepreneurship of African participants.
All participants were enrolled in a ten-week online entrepreneurship course led by Bocconi professors and African venture capitalists. The course taught participants how to take a startup idea from its inception through the presentation of a business plan.
At the beginning of the course, participants submitted an initial draft of a business plan. Then, they were randomly assigned to different interaction treatments and a comparison group. The subgroup of entrepreneurs who submitted the initial business plan before an announced deadline are considered “motivated individuals.” The results section focuses on these motivated participants because any effects are more likely to be detected in this subgroup, as they were more likely to participate in the interaction treatments.
At the end of the course, participants were asked to submit official business proposals, which were evaluated by a panel of 15 African professionals experienced in entrepreneurship programs. Proposals were evaluated on a scale of 1-5 in increasing order of quality. The proposals that received grades of 4 or 5 moved to a second-stage evaluation by investors, with the possibility of obtaining funding.
To understand how different channels and structures of communication between peers affect entrepreneurship, researchers tested three forms of peer interaction:
- The face-to-face groups met in person for two hours every other week.
- The virtual-within groups consisted of individuals of the same nationality who interacted through customized online platforms.
- The virtual-across groups consisted of individuals of mixed nationality who interacted through customized online platforms.
- The comparison groups participated in the online course but were not exposed to peer interaction.
Participants who received one of the peer interaction interventions were placed into randomly formed groups of 60 individuals. The peer interaction lasted for ten weeks, beginning two weeks after the start of the online course.
In order to test for whether the group composition matters for innovation, researchers first divided the sample into the following three samples based on nationality, then randomized the peer interaction intervention within each sample:
- The Uganda Sample: This sample consisted of 568 individuals living near Kampala. Individuals in this group were then randomly assigned to three equal-sized subgroups as follows: a comparison group, a face-to-face group, and a virtual-within group.
- The Large-Country Sample: This sample consisted of 3,333 individuals living in one of five countries designated as “large.” “Large” countries are those with enough participants to form groups of their own nationality. Individuals in this group were randomly assigned to a comparison group, a virtual-within group, and a virtual-across group.
- The Small-Country Sample: 1,057 individuals living in one of the 44 countries not designated as “large” were randomly assigned to two groups: a comparison group and a virtual-across group.
Researchers measured the likelihood of submitting a proposal and the first-stage grading of proposals as indicators of innovation performance.
Results and policy lessons
Results indicate that among motivated entrepreneurs, peer interaction was effective at increasing submission rates when the composition of groups was more similar (virtual-within country) and the interaction was most direct (face-to-face). Only virtual-within country interaction significantly increased business proposal quality.
Submission: In the Uganda Sample, the likelihood of submitting a proposal for participants in the face-to-face treatment group was 15 percentage points higher than the comparison group base of 55 percent. Those in peer groups of the same nationality (virtual-within country) for the Large-Country Sample had submission rates 4.8 percentage points higher than the comparison group base of 58 percent. Those in peer groups of mixed nationality (virtual-across) had no impact on submission rates.
Business proposal quality: Entrepreneurs in peer groups of the same nationality (virtual-within country) increased the quality of business proposals submitted compared to those who were not exposed to peer interaction. Virtual-across and face-to-face peer interactions did not have significant impacts on quality.
Group characteristics: The average baseline quality and the average experience of groups, as measured by whether or not participants had a business prior to the intervention, negatively affected the quality of proposals. Neither average quality nor average experience impacted submission rates. Researchers hypothesized that peers with prior business experience tended to provide discouraging feedback that may have negatively affected business quality of the proposals of their peers.
Additionally, an instrumental variable analysis of the exhaustive networking/communication data generated during the intervention showed that bilateral peer effects were significant, but operated differently depending on the treatment: they were significantly positive on submission only for same-nationality groups, and on business quality only for cross-country groups.
Researchers also employed a machine-learning procedure to further understand the type of discussions that were more useful for the formation of networks, what sort of communication methods they undertook, and how this impacted their innovation performance.
By analyzing face-to-face, virtual-within country, and virtual-across country peer interaction, the study can help policymakers understand how peer networks can promote innovation and entrepreneurship. Future research could further unpack the mechanisms through which peers interact and examine different types of interaction that could improve the design of peer networks.
