This trial measures the impact of an edutainment program specifically designed to promote entrepreneurship among young adult viewers in Egypt.

This experiment tests the impact of a program with the main goal of helping firms to attract new customers, expand markets, adapt their business model, and bounce back from the COVID-19 pandemic by boosting demand for their products.

Do capital grants improve microenterprise productivity? We use the lens of a production function to re-examine two previous randomised controlled trials that allocated capital to microenterprises. We find that productivity is higher for treated firms, and accounts for about 20-30 percent of the revenue effects of capital grants. Although long-run estimates are noisy, point estimates indicate that these productivity effects are sustained six years after the grants.

The model shows that managers and entrepreneurs make better decisions under uncertainty if they adopt a scientific approach in which they formulate and test theories.

This project aims to understand the determinants of adoption of a new technology by firms in Bangladesh's leather goods and footwear industry.

A randomised controlled trial has been performed in which 580 randomly selected pupils (aged 14-15) have been randomly assigned to participate in online programmes that focus either on entrepreneurship or on environmental issues. . The short-term results show that the programme focusing on entrepreneurship had a significantly positive influence on the participants’ entrepreneurial intentions, venture creation self-efficacy, entrepreneurial attitudes and perceived knowledge about entrepreneurship

We examine how the behavior of software developers changes in response to removing gamification elements from GitHub, an online platform for collaborative programming and software development. We find that the unannounced removal of daily activity streak counters from the user interface (from user profile pages) was followed by significant changes in behavior. Long-running streaks of activity were abandoned and became less common. Weekend activity decreased and days in which developers made a single contribution became less common.

This paper compares how two common incentive schemes affect innovative performance in a field experiment run in partnership with a large life sciences company.

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.

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.

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.

This field experiment was conducted in a sales firm to test whether improving knowledge flows between coworkers affects productivity.

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.
