In 2004 and 2005, the then Ministry of Economic Affairs issued innovation vouchers to SMEs to promote cooperation and knowledge exchange between companies and knowledge institutes in the field of innovation. The underlying idea was that more new products, services and/or processes can be developed with more knowledge exchange. This innovation can in turn lead to an increase in turnover and productivity, which ultimately leads to more prosperity.

Lack of secular economic opportunity is believed to be related to social unrest, engagement in terrorism, and association with radical groups. In conflict areas, difficulties accessing economic opportunity and employment are often exacerbated by movement restrictions and investor concerns about safety of physical plant and other capital investments that might enhance employment opportunities. Recent advances in cloud-computing and software-driven services present the promise of a solution through cloud-based entrepreneurial activity.

The engagement with industry actors is a key element in the transition towards an entrepreneurial university model. The purpose of this paper is to explore the university–industry collaboration (UIC) drivers from the industry side. It analyses how, and to what extent, policy interventions could increase the engagement of industry actors in UICs.

What is the effect of exposing motivated youth to firm management in practice? To answer this question, we place young professionals for one month in established firms to shadow middle managers. Using random assignment into program participation, we find positive average effects on wage employment, but no average effect on the likelihood of self-employment. Within the treatment group, we match individuals and firms in batches using a deferred-acceptance algorithm. We show how this allows us to identify heterogeneous treatment effects by firm and intern.

Bertrand, M., Crépon, B.

We assess whether imperfect knowledge of labor regulation hinders job creation at small and medium-sized firms. We partner with a labor law expert in South Africa that provides information to local firms about major topics regarding labor regulation via newsletters and access to a specialized website. We randomly assign 1800 firms to receive free access to this information service for a 21-week period. Three-quarters of the firms offered the service took it up.

Organizations constantly strive to unleash their entrepreneurial potential to keep up with market and technology changes. To this end, they engage employees in practices like corporate crowdsourcing, incubators, accelerators or hackathons. These organizational practices emulate independent “green-field” entrepreneurship by relinquishing hierarchical control and granting employees autonomy in the choices of how to conduct work.

We study gender and race in high-impact entrepreneurship within a tightly controlled random field experiment. We sent out 80,000 pitch emails introducing promising but fictitious start-ups to 28,000 venture capitalists and business angels. Each email was sent by a fictitious entrepreneur with a randomly selected gender (male or female) and race (Asian or White). Female entrepreneurs received an 8% higher rate of interested replies than male entrepreneurs pitching identical projects. Asian entrepreneurs received a 6% higher rate than White entrepreneurs.

Differences in productivity may be driven by heterogeneity in skills but also the extent to which individuals are motivated to do their job over and above financial compensation. The proposed research will unpack the sources of intrinsic motivation and test whether these can be leveraged to increase productivity. To do so we will run a cross-country field experiment in collaboration with a multinational company that offers one-day workshops that guide employees on how to connect their individual purpose with their work.

Despite mounting interest in growth mindset interventions, this approach has yet to be applied to the domain of entrepreneurship. In the present research, we developed and tested if a growth mindset intervention could be leveraged to promote students’ entrepreneurial self-efficacy and if this, in turn, predicted career development (i.e., academic interest, career interest, task persistence, and academic performance). We report on our findings, from an Open Science Framework (OSF) preregistered study, that is a randomized controlled trial implementing a growth mindset intervention.

Tobro, T., Ulltveit-Moe, K., H., Moxnes, A.

This study is a randomized controlled trial (RCT) on the effects of mentoring on SMEs in Norway. We aim to get a better understanding of firm development and dynamics in the presence of public interventions. Does mentoring affect firm performance and firm-survival? Does it matter what type of state aid a firm is granted; mentoring versus the financial equivalent of the service?

We explore how variation in entrepreneurs' displayed passion affects informal investor interest in start-up ventures by examining neural responses to entrepreneurs' pitches using functional Magnetic Resonance Imaging (fMRI). We find that founders displaying high passion increase investor neural engagement by 39% and investor interest in the venture by 26% over those displaying low passion. A one standard deviation increase in neural engagement is associated with an 8% percent increase in investors' interest in investing in a start-up company relative to the mean.

We construct a model of technology adoption with agents differing on two dimensions: their cognitive ability and their receptiveness to advice. While cognitive ability unambiguously speeds adoption, receptiveness to advice may speed adoption for individuals with low cognitive ability, but slow adoption for individuals with high cognitive ability. We conduct economic experiments measuring US farmers' cognitive ability and receptiveness to advice and examine how these characteristics impact their speed of adoption of genetically modified (GM) corn seeds.

Graff Zivin, J., Lyons, E.

Existing theories and empirical research on how innovation occurs largely assume that innovativeness is an inherent characteristic of the individual and that people with this innate ability select into jobs that require it. In this paper, we investigate whether people who do not self-select into being innovators can be induced to innovate, and whether they innovate differently than those who do self-select into innovating.

Ebert, C., Prabhu, J., KC, R.

This study explores how individuals develop habitual perspectives from repetitive tasks they enact over time, and how these deeply ingrained habits of perspective influence creativity. Further, this study proposes that habits of perspective are resistant to the creativity-stunting effect of financial incentives.

Anderson, S.J., , Bilal Z., Chandy, R.

This paper examines the impact of improvements in marketing skills relative to finance skills among small-scale entrepreneurs. It addresses three important questions: (1) What is the impact of marketing or finance skills on business profits? (2) How do improvements in marketing and finance skills respectively affect different business outcomes? (3) When are increases in marketing relative to finance skills more beneficial?

We use a randomized controlled trial to demonstrate that inexperienced female microenterprise owners in a Kenyan slum benefit from mentorship by an experienced entrepreneur in the same community. Mentorship increases profits by 20 percent on average with initially large effects that fade as matches dissolve. We conduct a formal business education intervention, which has no effect on profits despite changes in business practice.

Increasing evidence indicates the importance of management in determining firms’ productivity. Yet, causal evidence regarding the effectiveness of management practices is scarce, especially for high-skilled workers in the developed world. In an eight-month field experiment measuring the productivity of captains in the commercial aviation sector, we test four distinct management practices: (i) performance monitoring; (ii) performance feedback; (iii) target setting; and (iv) pro-social incentives.

What determines the adoption of electronic-payment instruments? Do these instruments impact business outcomes, in particular access to finance? To shed light on these questions, we conducted a Randomized-Controlled-Trial with Kenyan SMEs. Our experiment released barriers to adopt a novel payment instrument. We uncover that the adoption barriers were binding for a large portion of the firms and that firms' financial transparency interacted with the decision to adopt. After sixteen months, treated businesses were more likely to feel safe and had more loans.

This paper studies whether small-scale businesses can learn and adopt protable practices of their successful peers. We identify such practices through a detailed business survey in urban Indonesia and disseminate the information to a randomly selected sample of small retailers through a professionally developed handbook. An orthogonal subgroup is provided additional support through business role models, and another through individualized business counseling. We find a significant increase in the adoption of profitable practices in all sub-groups of retailers.

We investigate the impact of a program providing asset transfers and business training to low income individuals in Chile, and asked whether a larger asset transfer would magnify the program's impact. We randomly assigned participation in a large scale, publicly run micro-entrepreneurship program and evaluated its effects over 45 months. The program improved business practices, employment, and labor income. In the short run, self-employment increased by 14.8/25.2 percentage points for a small/large asset transfer.

As the largest encyclopedia in the world, it is not surprising that Wikipedia reflects the state of scientific knowledge. However, Wikipedia is also one of the most accessed websites in the world, including by scientists, which suggests that it also has the potential to shape science. This paper shows that it does. Incorporating ideas into Wikipedia leads to those ideas being used more in the scientific literature.
