This article studies technology adoption in a cluster of soccer-ball producers in Sialkot, Pakistan. We invented a new cutting technology that reduces waste of the primary raw material and gave the technology to a random subset of producers. Despite the clear net benefits for nearly all firms, after 15 months take-up remained puzzlingly low.

Brudevold-Newman, A., Honorati, M., Jakiela, P., Ozier, O.

This study presents results from a randomized evaluation of two labor market interventions targeted to young women aged 18 to 19 years in three of Nairobi's poorest neighborhoods. One treatment offered participants a bundled intervention designed to simultaneously relieve credit and human capital constraints; a second treatment provided women with an unrestricted cash grant, but no training or other support.

We present novel evidence from the results of a randomized controlled trial on the role that information plays in the perceptions of the benefits and costs of exporting. We first present results from a baseline survey of approximately 1,000 UK manufacturing firms to show that non-exporters hold substantially more negative beliefs about the costs and benefits of exporting relative to exporters.

Accredited investors finance more than 75,000 U.S. startups annually. We explain how training aspiring entrepreneurs to pitch their new business ideas to these investors affects their odds of continued funding discussions. We model accredited investors’ decision to continue investigation as a real option whose value is a function of their experience and the information contained in the entrepreneurs’ pitches. We derive four hypotheses from the model, which we test through a field experiment that randomly assigns pitch training at four elevator pitch competitions.

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 Notably, these effects persist two years after microfinance was withdrawn from Hyderabad.

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.

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.

In the context of a basic, short-term data entry job, unannounced provision of public recognition to employees yielded an economically significant increase in performance. Results suggest that recognition works best when it is provided exclusively, but not too exclusively. The performance increases in exclusive recognition are mainly driven by strong positive responses of non-recipients, which is most likely due to conformity preferences.

Field experiments have the potential to provide unambiguous causal evidence on innovation topics while simultaneously assisting organisations with their innovation.

Boudreau, K., Guinan, E., Lakhani, K., Riedl, C.

This paper focuses on the evaluation of frontier scientific research projects and argues that the intellectual distance between the knowledge embodied in research proposals and an evaluator's own expertise systematically relates to the evaluations given.

Bechtold, S., Buccafusco, C., Sprigman, C. J.

All creativity and innovation build on existing ideas. Authors and inventors copy, adapt, improve, interpret, and refine the ideas that have come before them. The central task of intellectual property (IP) law is regulating this sequential innovation to ensure that initial creators and subsequent creators receive the appropriate sets of incentives. Although many scholars have applied the tools of economic analysis to consider whether IP law is successful in encouraging cumulative innovation, that work has rested on a set of untested assumptions about creators’ behavior.

Schaner, S.

I use a field experiment in rural Kenya to study how temporary incentives to save impact long run economic outcomes. Study participants randomly selected to receive large temporary interest rates on an individual bank account had significantly more income and assets 2.5 years after the interest rates expired. These changes are much larger than the short-run impacts on experimental bank account use and almost entirely driven by growth in entrepreneurship.

Gallus, J.

This natural field experiment tests the effects of purely symbolic awards on volunteer retention in a public goods context. The experiment is conducted at Wikipedia, which faces declining editor retention rates, particularly among newcomers. Randomization assures that award receipt is orthogonal to previous performance. The analysis reveals that awards have a sizeable effect on newcomer retention, which persists over the four quarters following the initial intervention.

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.

Field, E., Jayachandran, S., Pande, R., Rigol, N.

Women may face more constraints than men to becoming entrepreneurs, but are not poor entrepreneurs. A potentially important factor limiting financial inclusion efforts is inadequate peer support among many women who have potential as entrepreneurs.

Bulte, E., Lensink, R., Vu, N.

This trial evaluates the impact of a business training for female clients of a microfinance institution in northern Vietnam, and considers the impact on business knowledge, practices, and outcomes, as well as firm entry and exit decisions.

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.

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.

Nathan, M., Overman, H., Olmo, S.

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.

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.

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.
