We investigate how knowledge similarity between two individuals is systematically related to the likelihood that a serendipitous encounter results in knowledge production. We conduct a field experiment at a medical research symposium, where we exogenously varied opportunities for face-to-face encounters among 15,817 scientist-pairs. Our data include direct observations of interaction patterns collected using sociometric badges, and detailed, longitudinal data of the scientists' postsymposium publication records over 6 years.

Despite the widespread popularity of entrepreneurship education, there is thin evidence on its effectiveness in improving employment outcomes over the medium to long-term. A potential time lag between entrepreneurial intentions and actions is sometimes presented as a reason why employment impacts are rarely observed. Based on a randomized control trial among university students in Tunisia, this paper studies the medium-term impacts of entrepreneurship education four years after students’ graduation.
This paper hypothesizes that many productive firms in poor countries stagnate due to informational barriers to winning wholesale contracts.
Entrepreneurial motivation is important to the process of economic growth. However, evidence on the motivations of innovative entrepreneurs, and how those motivations differ across fundamental characteristics, remains scant. We conduct three interrelated field experiments with the Massachusetts Institute of Technology Inclusive Innovation Challenge to study how innovative entrepreneurs respond to messages of money and social impact and how this varies across gender and culture.
Cavendish Enterprise's Business Boost trial project involved providing young small firms - typically micro-businesses - with a treatment involving a series of workshops designed to enhance productivity. This was provided largely as a top-up to an advice and mentoring programme called 'Start and Grow'. The project was part of the government's Business Basics Programme which has the core aim of identifying cost effective, yet productivity enhancing, programmes of business support for SMEs which can be run at scale throughout the country.
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.
This paper explores what might motivate employees to participate in internal crowdsourcing, a peer-based approach to innovation.
This paper discusses implementing a lab-in-the-field experiment with 334 Turkish loan officers to test for the presence, and learn about the mechanisms, of gender discrimination in small business lending.
This paper investigates the role of information sharing among experts as the driver of evaluation decisions.
Identifying the most promising business ideas is key to the introduction of novel firms, but predicting their success can be difficult. It is argued that if entrepreneurs adopt a scientific approach by formulating problems clearly, developing theories about the implications of their actions, and testing these theories, they make better decisions.
In this paper, a randomised experiment measures the effects of workers at an automobile manufacturing firm evaluating their managers on worker and firm outcomes.
The main objective of this project is to test the effects of feedback with and without relative ranking scores on SMEs and first-time applicants performance in the funding program “General Programme” of the FFG, and business performance after the program. The feedback for each firm will be based on evaluations scores of the respective funding proposal from project evaluators in the FFG. The participants in the RCT are all Start-ups, SMEs, and large companies who are first-time applicants accepted into the funding program in the timespan of a year.
The study is an impact evaluation of a training program that induced SMEs to adopt broadband connections, establish presence on online retail and potentially export their goods or services.
This paper investigates the impact of management training programs on garment clusters in Vietnam and Tanzania.
Using survey and register data, this experiment estimates the effects of the information treatment brochure on awareness of WeGebAU, on take-up of WeGebAU and other training, and on subsequent employment.
Many Start Ups and Small & Medium Enterprises (SME) have an immature methodological approach to innovation and half of them present a clear deficit in innovation know-how, pointing towards a need for extra support. The efficacy of two approaches to building knowledge and increasing awareness of non-technical innovation among Start Ups and Small and Medium Enterprises (SME) will be tested.
This study investigates the extent to which training can be remotely taught to small groups via Zoom sessions, with a sample of female microenterprise owners recruited from throughout Mexico and Guatemala.
This article studies the effects of the adoption of artificial intelligence on teams and their performance and coordination in a laboratory experiment. We posit that automation decreases organizational performance, interferes with team member coordination, and leads to behavioral changes in human co-workers. We randomize the introduction of automated players and new hires into "laboratory firms" (Weber and Camerer, 2003) who must coordinate in teams playing a game on the Nintendo Switch console.
This paper reports on a large platform-based field experiment in which 97,696 U.S. university-educated individuals were given the opportunity to join a tech-related product development activity.
This paper asks to what extent firms are aware of readily available information on key competitor decisions, and how this information impacts firms’ strategic choices.
This trial proposes to evaluate a model for scaling up affordable access to effective STEM education through national online education platforms.
Innovative firms with good ideas may still struggle to fine-tune them to the stage where they can attract outside funding. We conduct a five-country randomized experiment that tests the impact of an investment readiness program. Firms then pitched their ideas to independent judges. The program resulted in a 0.3 standard deviation increase in the investment readiness score. Two years later, the average impacts on firm investment outcomes are positive, but small in magnitude, and not statistically significant.
In this study, we empirically examine the effect of sharing information with close or distant competitors as part of an incubation program. There is recent evidence of substantial heterogeneity in acceleration programs, with qualitative research highlighting that the main benefit for participants to these programs is the increased exposure to information and the feedback they obtain. Such exposure helps balance the bounded rationality of founders.
This paper evaluates the effect of joint tasks on the creation of network ties with data from a novel field experiment with 112 aspiring entrepreneurs.
Indian weaving firms are visited again nine years after a randomized experiment that changed their management practices.
This field experiment was conducted in a sales firm to test whether improving knowledge flows between coworkers affects productivity.
This trial investigates the best way to help agents perform better, as firms providing products and services to low income Base of the Pyramid (BOP) customers are increasingly utilizing independent contractor agents rather than employees in their distribution models.
This paper tests the role of three behavioral biases: present bias, limited memory, and overconfidence about memory.
A randomized control trial in central Tanzania, centered on the production and distribution of a ”Yellow Pages” phone directory with contact information for local enterprises.
The use of machine learning (ML) for productivity in the knowledge economy requires considerations of important biases that may arise from ML predictions. We define a new source of bias related to incompleteness in real time inputs, which may result from strategic behavior by agents. We theorize that domain expertise of users can complement ML by mitigating this bias. Our observational and experimental analyses in the patent examination context support this conjecture.
