Bjorvatn, K., Cappelem, A., Helgesson Sekei, L., Ø. Sørensen, E., Tungodden, B.

This field experiment involved more than 2,000 secondary school students, where the treatment group was incentivised to watch an edutainment show.

Bechthold, L., Rosendahl Huber, L.

This study draws on social learning theory and research concerning role model effects to understand how exposure to female entrepreneurial role models influences the development of entrepreneurial self-efficacy, attitudes and intentions among female students. The results presented are from a field experiment including data from 547 students and 98 entrepreneurs.

Lafortune, J., Riutort, J., Tessada, J.

Using a randomized experiment in Chile we study the impact role models have in the context of a training program for micro-entrepreneurs. We show that being in a group randomly chosen to be visited by a successful alumnus of the program increases household income one year after, mostly due to increased business participation and business income.

Eesley, C., Wu, L.

Entrepreneurial activity is an important source of innovation in information technology products and services. Prior literature suggests that IT innovators should be agile, adaptive, willing to change direction frequently, and acquiring the necessary resources to facilitate the change. Social networks have been suggested as essential for acquiring information and resources and therefore in facilitating the venture development process.

Eesley, C., Wang, Y.

How do different sources of social influence impact the likelihood of entrepreneurship? Using a longitudinal field experiment with a pre-test/post-test design, random assignment to an entrepreneur mentor of a student increases the likelihood of entrepreneurial careers, particularly for students whose parents were not entrepreneurs.

Can improved access to credit jump-start microenterprise growth? We examine subjects in urban Hyderabad, India, six years after microfinance–an intervention commonly believed to lower the cost of credit and spark business creation–was randomly introduced to a subset of neighborhoods. We find large benefits both in business scale and performance from giving “gung-ho entrepreneurs” (GEs)–those who started a business before microfinance entered–more access to microfinance. Notably, these effects persist two years after microfinance was withdrawn from Hyderabad.

Hoogendoorn, S., Parker, S.C.

This paper explores the relationship between cognitive abilities and team performance in a start-up setting in a field experiment in which 573 students in 49 teams started up and managed real companies. Performance in this setting hinges on three tasks: opportunity recognition, problem solving, and implementation. Cognitive ability at the individual level has a positive effect on opportunity recognition and problem solving but no clear effect on implementation.

Åstebro, T., Hoos, F.

We use two sequential RCTs to study the impact of a twice-executed six-month intensive training program costing about 12,000 euros per participant to encourage social entrepreneurship among youth. The first year training effort provided no robust treatment effects. Results were used to redesign and improve the training. The second year effort provided treatment effects on venture actions, venture creation, one leadership characteristic, one non-cognitive skill, and on subsequent work experience in startups.

Boudreau, K., Lakhani, K., Menietti, M.

In the context of online developer tournaments this study found that added rivalry is likely to induce higher performance given that failing to exert effort will reduce the likelihood of winning a prize. Tournament organizers can leverage contest size, dividing competitors by ability, and opening entry to all, as policy tools to manipulate the performance of competitors, particularly when changes allow the reallocation of prize money.

Kesavan, S., Rout, S.

This RCT will pilot Self-Accelerated Startups (SAS), a new peer-selection based entrepreneurship support model for idea-stage companies and student startups that uses collective bootstrapping on the lines of self-help groups in the social sector. In this model, prospective entrepreneurs meet regularly in groups for a pre-defined mentorship period and make small monthly contributions to a “seed fund”. At the end of this phase, the self-mobilized corpus is awarded as startup capital to one or two members by the rest of the peer group in return for equity in these startups.

Valdivia, M.

With millions of women around the developing world thrown into self-employment but with low productivity, increasing the profitability of their businesses is highly relevant for poverty reduction and gender equity.

Gertler, P.

This study aims to carry out an evaluation of the long-term impacts of an innovative school-based intervention designed to enhance the ability of youth to engage and succeed in both formal employment and entrepreneurial activities in Uganda, ultimately leading to improvements in livelihood. The findings will inform future interventions (in Uganda, Rwanda, and Kenya) to help more young people overcome obstacles to successful entrepreneurship and labor market participation, such as gender-related barriers, thereby improving their livelihoods and socioeconomic security.

Huber, L. R., Sloof, R., van Praag, M.

This entrepreneurship education programme with final year primary school students in the Netherlands showed significant effects on student's non-cognitive entrepreneurial skills following the intervention.

Chioda, L., Gertler, P.

Using an OLS regression estimator with clustered standard errors, the analysis finds that, out of the twelve outcome variables used to assess the effectiveness of the program of achieving its stated goals, they have reached their target for the outcome variables of business ownership, overall income level, community project ownership, savings behaviour and self-efficacy but not for the indicators of paidemployment prevalence, business or employment income, holding of a school leadership position, business planning, financial literacy or creativity.

Crépon, B., Duflo, E., Huillery, E., Pariente, W., Seban, J.

The Paris School of Economics proposed a project to the Haut-Commissariat aux Solidarités Actives (French Minister for Active Solidarity against Poverty) to evaluate the impact of one of Adie’s programs, CréaJeunes. The “Association pour le droit à l’initiative économique” (Adie), is an NGO that aids people in creating their own business. The program is designed to encourage and support young people employment and entrepreneurship, particularly in poorer neighborhoods.
