In this study we assess the effects of a decentralized extension program and an additional video intervention on the adoption of integrated soil fertility management (ISFM) among 2,382 farmers in Ethiopia using a randomized controlled trial. ISFM should enhance soil fertility and productivity by combining organic and inorganic soil amendments. We find that both extension-only and extension combined with video increase ISFM adoption and knowledge.

A classical approach to collecting and elaborating information to make entrepreneurial decisions combines search heuristics such as trial and error, effectuation, and confirmatory search. This paper develops a framework for exploring the implications of a more scientific approach to entrepreneurial decision making. The panel sample of our randomized control trial includes 116 Italian startups and 16 data points over a period of about one year.

This paper studies the impact of a financial education program for top managers of medium and large enterprises in Mozambique through a randomized controlled trial (RCT). We use survey data and financial reporting data to show consistent evidence that managers adjust some financial policies in response to the education program. The largest treatment effects are on short-term financial policies related to working capital, generating a positive impact on cash flows due to reductions in account receivables and inventories.

A field experiment in Sri Lanka provided wage subsidies to randomly chosen microenterprises to test whether hiring additional labor benefits such firms, and whether a short-term subsidy can have a lasting impact on firm employment. Using 12 rounds of surveys to track dynamics four years after treatment, we find that firms increased employment during the subsidy period. Treated firms were more likely to survive, but there was no lasting impact on employment, and no effect on profitability or sales either during or after the subsidy period.

While prior research shows a significant gender gap in traditional equity financing, with mostly male investors who prefer male founders, emerging evidence indicates that gender gaps in funding may not translate to rewards-based crowdfunding, where female entrepreneurs may have an advantage, particularly with female investors. We seek to examine founder gender preferences in the context of equity crowdfunding, which represents a direct counterpart to traditional equity financing and which is a “higher-stakes” context than rewards-based crowdfunding.

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.

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.

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.

Many innovative start-ups and small and medium-size enterprises have good ideas, but do not have these ideas fine-tuned to the stage where they can attract outside funding. Investment readiness programs attempt to help firms to become ready to attract and accept outside equity funding through a combination of training, mentoring, master classes, and networking.

We design two laboratory experiments to analyze the causal effects of competition on step-by-step innovation. Innovations result from costly R&D investments and move technology up one step. Competition is inversely measured by the ex post rents for firms that operate at the same technological level, that is, for neck-and-neck firms. First, we find that increased competition leads to a significant increase in R&D investments by neck-and-neck firms.

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.

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.

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.

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.

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.
