We conducted a field experiment to identify the causal effects of extrinsic incentive cues on the sorting and performance of nascent social entrepreneurs. The experiment, carried out with one of the United Kingdom’s largest support agencies for social entrepreneurs, encouraged 431 nascent social entrepreneurs to submit a full application for a grant competition that provides cash and in-kind mentorship support through a onetime mailing sent by the agency.

How do different types of proximity impact collaboration and knowledge generation? How should we design research campuses to maximize the probability of breakthrough innovation taking place? Although information and communication technology has substantially lowered the cost of remote interactions, physical space and geographic proximity still play a major role in inventive activity. This project will explore how a research-intensive academic campus should be designed to increase the probability of breakthrough innovations taking place.

Crowdfunding is a recent and rapidly growing method of raising funds for early-stage companies. It minimises the cost and effort involved in raising start-up funds compared to traditional equity funding methods such as venture capital investment. Very little systematic, non-survey research has been conducted into these methods of funding new ventures, however. ‘The wisdom of crowds in equity crowdfunding’ aims to fill this gap.

Microentrepreneurs in developing countries face complex financial management challenges. Many entrepreneurs do not have the financial skills to address these challenges and traditional classroom-based financial training has not been shown effective in changing behavior or improving financial outcomes. What is the most effective way to equip microentrepreneurs with the necessary skills to address their financial management challenges? Traditional financial education curricula have shown very mixed results for improving knowledge and financial practices among microentrepreneurs.

Kuhn, J.M., Thompson, N.

Competition between firms to invent and patent an idea, or “patent racing,” has been much discussed in theory, but seldom analyzed empirically. This article introduces an empirical way to identify patent races, and provides the first broad-based view of them in the real world. It reveals that patent races are common, particularly in information-technology fields. The analysis is then extended to get the causal impact of winning a patent race, using a regression-discontinuity approach.

Working with one of the largest tech incubators in the UK, this trial will deploy a multi-site RCT in two different cities. After pre-selection, entry into the incubator will be randomised for 100 firms per site. The experiment will then explore post-treatment outcomes including survival, recombination, and changes in post-treatment revenue, employment and level of external finance raised.
Using interviews and surveys we will also explore whether different parts of the treatment vary in their effectiveness (e.g. mentoring versus peer to peer interactions).

Kaur, S., Kremer, M., Mullainathan, S.

Self-control problems change the logic of agency theory by partly aligning the interests of the firm and worker: both now value contracts that elicit future effort. Findings from a year-long field experiment with full-time data entry workers support this idea. First, workers increase output by voluntarily choosing dominated contracts (which penalize low output but give no additional rewards for high output). Second, effort increases closer to (randomly assigned) paydays.

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.

Many resources, such as business acumen are thought to feed into entrepreneurial success. However, an open question is whether the tools and frameworks available to nascent startups are causally related to their successes in the areas of financing, employment and revenue growth, valuations, etc. In this study, we use a large-scale RCT to assess the impact of entrepreneurship skills training on startup decisions and outcomes across the U.S. In the study, startups associated co-working spaces are offered payment to complete a series of surveys tracking their outcomes over two years.

Rosendahl Huber, L.

This study reports on a randomized field experiment conducted in the Netherlands to estimate the (long-term) effect of a short personalized tax training program on the performance and tax compliance of first-time entrepreneurs. The tax training was expected to have an impact on business performance and different aspects of tax compliance through better financial decision making and more relevant tax knowledge.

Heite, J., Rosendahl Huber L., Kleine, M.

The Innovation Voucher Program analyzed in this study operates as a randomized controlled trial (RCT). This allows estimating the causal effect of the voucher on innovation and growth measures of beneficiaries, as well as their business outcomes in general. As a result, the evidence might be used to enhance voucher schemes and to provide further policy advice on how to effectively support small and medium-sized enterprises and their innovation activities in the future.

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.

Micro-entrepreneurs in developing countries are often constraint by inefficient supply chains, facing high travel costs and high prices in purchasing their inventory. At the same time, due to their small scale, they buy in small quantities, limiting their benefit from economies of scale, whether in bulk discounts or transport efficiencies. Small-scale food vendors in Bogotá, whose customers are residents of low-income neighborhoods, face these very issues.

The Growth Impact Pilot, launched in April 2014, is a research project on the impact of business advice (coaching), supported by the UK Government. The Growth Impact Pilot will assess whether the provision of Growth Accelerator coaching is the reason why firms on the service achieve high rates of growth, or whether this growth would have happened anyway. It is designed to assess the impact of coaching by comparing two groups:

Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. We conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics. The rule-of-thumb training significantly improved firms' financial practices, objective reporting quality, and revenues.

This paper explores the effectiveness of goal setting and accountability within group-based entrepreneurship initiatives in creating human capital. The study uses a randomized cluster trial to compare the experimental and control groups of entrepreneurs. The results suggest that frequent goal setting and accountability in group settings provides a greater number of learning experiences and human capital development opportunities available to entrepreneurs than those that did not engage in the same level of goal setting.

We investigate the relationship between employees' and managers' training and firm performance using a policy intervention that randomly assigned training support to small‐ and medium‐sized enterprises in the UK accommodation and food service sector. Because the number of firms self‐selected into training exceeded available places, training was randomly assigned to some firms, resulting in a randomized natural experimental design that allowed us to identify the average effect of training on treated firms.

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.

Levitt, S., and Neckermann, S.

This meta-analysis of field experimental evidence on firm-employee relationships finds strong evidence that financial incentive increase output, and that non-financial approaches and social relations also have important impacts. However, many important topics have not been studied yet using field experiments, including recruiting, worker promotion, and training.

Dupas, P.

A randomised field experiment in Kenya uses differing levels of subsidies for an innovative bed net to suggest that temporary subsidies help short-term adoption rates of new (health) technologies and can perhaps have an effect on long-term adoption rates due to the learning experience.

Bareket-Bojmel, L., Hochman, G., Ariely, D.

In the context of a semiconductor factory in Israel, experimenting with different types of incentives yielded results that provide some guidance for organisations trying to motivate their employees, showing that incentives of small magnitude can motivate employees to perform better at low or insignificant cost. Also, simply allowing employees to choose their preferred form of incentive can neutralize the possible negative effect of cash bonuses on intrinsic motivation.
